The concept and health examination mentality

1, without any discomfort, they don't need to do health inspection?
NO, NO uncomfortable doesn't mean all healthy. In no self-conscious symptom, appearance also don't see in the stage, sickness, the health check regularly early screening out a potential pathogenic factors or dysfunction of the situation, achieve inchoate discovery, inchoate cure effect.
2, body most uncomfortable, it is the best time to do check?
NO, the body does not timely medical treatment should be as soon as possible. The purpose of the health examination in the disease, is the hope not have obvious symptoms before, check out the pathogenic factors and early treatment, when already in acute episode of disease, should first treatment for diseases, then do health check stable, so don't put the cart before the horse.
3, everybody, need not do health inspection?
NO, above 30 regardless of gender, must be doing regular health checks. Disease mostly because genetic, living environment and living habits and other factors and gradual happen through scientific instruments, the correct detection, which can effectively help prevent or delay the happening of the disease, the earlier began to effect the better. Especially young people always is the family of the important pillars in modern society, coupled with the family is in the majority, maui, any party once both sides of husband and wife, the family the pace of life is sick in confusion. Therefore, every adult must strengthen to own health alert, in order to avoid oneself regret, family pain.
4, the child still small, don't do health inspection?
NO, the children's health inspection stress to the body and mental development, is a specialized knowledge, must by a specialist, so you can choose the suitable age children age (points classification) screening programs.
5, bought insurance, no additional money do check?
O, insurance company's additional medical treatment insurance, general health inspection fee is not payment, even if due to illness hospitalization, also cannot once completed all screening program, is caused extremely easily omissions, cannot inadvertent.
6, physical examination and health check the same?
NO, not the same. Physical examination general for professional physical check-up, life check-up, entrance, military service and a driver's license, etc, the project is simple. Health inspection is designed for the United Nations world health organization (the W.H.O.) advice, and cooperate with people's needs, design a comprehensive health check the integrity of the required project content.
7, a general professional inspection, healthcare check-up, old man screening, should be enough?
NO, these checks project content is not equal to the comprehensive health check project content. Professional inspection is mainly for occupational disease, check project because of working property different and different.
8, don't check, a check nothing wrong with everywhere is illness, why bother?
NO, delay will delay the mentality found early time. Disease have points, in line with health examination priorities early screening out pathogenic factors, can adjust habits or timely early, it not only can avoid disease doctor happened or worse, more can reduce the pain and disease burden.
9, check out the problem still must go to see a doctor, will only more trouble?
NO, HuiJiJiYi absolutely will keep the tail from wagging the dog. Early screening out as soon as possible, can accept abnormalities in the diagnosis and treatment of specialized subject doctor, this is the most important function of health examination, never considered trouble, lest the future regret.
10, in old age, if defective suddenly not to walk, why worry so much?
NO, in old age, body have trouble, does not mean that will immediately death and freedom from pain. Although everyone want to (live longer, ill late, die quickly). But in fact not everyone can so lucky. Based on respect for life, let old age live with dignity, reduce the economic burden and family pain, the elderly are more to live healthy.
11, the check everything is normal, later will no longer examined?
NO, the physical condition is always change, need long-term note and maintenance. Check the results are normal, says check (usually fall in value, the scope of reference) who could really there is no underlying disease inside, may also have disease, but for change is slight that undetectable. Besides the health of human body with time, age, lifestyle and work pressure and change, so still needs every year regularly do health examinations, and self body assessment, early detection problems, early improvement.
12, body uncomfortable, just go to the inspection and serologic examinations?
NO, the body unwell best to hospital by doctors decided, to do those check, if you should serologic examinations to inspection report to the doctor as a diagnostic reference.
13, don't have to tell the doctor much history, can test the doctor exactly accurate prohibit?
NO, sourly exams doctor since mistakenly health instead. Personal past history is very precious to the doctor, the doctor can test results, by now with the past medical history to diagnose diseases, such as attitude with exam doctor examined, easy to mislead doctors make wrong judgment, for their own health, do not have this mentality.

SMT(Surface Mounted Technology)

SMT(Surface Mounted Technology) Electronics assembly industry is now one of the most popular technology and process.
SMT differ
High density assembly, electronic products small volume, light weight, patch of components of the bulk and weight only traditional cartridge elements 1/10 or so, generally USES the SMT later, electronic product size decreased 40% ~ 60%, and the weight 60% ~ 80%.
High reliability, ant-vibration ability. Solder defects is low.
High frequency characteristic well. Reduce the electromagnetic and rf interference.
Easy to realize the automation and improve production efficiency. Reducing cost up to 30% ~ 50%. Save material, energy, equipment, human, time, etc.
Why should use SMT
Electronic products used in pursuit of miniaturization, already cannot narrow punched plugin components.
Electronic product function more complete, the integrated circuit (IC) has no perforation components, especially large-scale, high integration IC, had to adopt surface patch components.
Products PiLiangHua, automated production with lower cost, the manufacturer to produce high yield, high quality products to meet customer demand and strengthen market competitiveness
Electronic components development, integrated circuit (IC) development, semiconductor materials to multiple applications.
Electronic technology revolution is imperative, chasing after the international trend.
SMT basic process elements
Printing (or dispensing) - - > mounted - - > (cured) - - > reflow soldering - - > > testing - clean - - > repair. -
printing
Its role is to its solder paste or patch of the PCB soldering to glue plate, preparing for the components of welding. Equipment used for printing presses SMT processing workshop
(solder paste printer), located in the SMT production line forefront.
dispensing
For now the circuit board is mostly used to prevent second patch, double down the components when solder paste into because of melting and fall off, so again in input face plus deck gum machine, it is will glue drops to the PCB's fixed position, its main effect is fixed to a PCB components. Equipment used for dispensing machines, is located in the forefront of the SMT production line behind or testing equipment. Sometimes due to the customer request output surface also need some glue, and now many small factories all need not glue machine, if input surface components bigger when employing worksite glue.
mounted
Its role is accurate installations assembly components will surface of fixed position to the PCB. Equipment used for placement machine, located in SMT production line behind in printing machine.
curing
Its role is to melt, thereby patch rubber surface mount components and PCB firm bonding together. Equipment used for curing furnace, located in SMT lines behind the placement machine.
Reflow soldering
Its role is to melt, make surface solder paste with PCB assembly components firm bonding together. Equipment used for reflow oven, located in SMT lines behind the placement machine.
cleaning
Its role is to assemble good PCB above the harmful to human body welding residual such as flux, etc to eliminate. Equipment used for cleaner, position can not fixed, online, also can not online.
detection
Its role is to assemble good PCB assembly welding quality and quality detection. Equipment used a magnifying glass, microscope, online tester (ICT), flying probe tester, automatic optical inspection (AOI), X - RAY detection system, function tester, etc. According to the need of place, can configure test in line appropriate place.
repair
Its role is to detect malfunction redo the PCB. Tools for iron and repair workstation, etc. In any position in line configuration. 

Bootstrap agreement (BOOTP)

Bootstrap agreement (the BOOTP) is a based on IP/UDP protocol agreement, it can let no disk from a central server station get IP address, for LAN in the distribution of dynamic IP address workstation no disk, it doesn't need to each user to place a static IP address. Use the BOOTP protocol, generally includes the bootstrap protocol server and bootstrap agreement client two parts.
application
The agreement mainly used to have no disk workstation LAN, client access IP addresses are as follows: first, the process of by the BOOTP starting client start-up code, this time client is not IP address, use with IP address broadcast to network 255.255.255.255 issued IP address inquires requirements. Then, run the BOOTP protocol server receives the request, according to the MAC address supplied in the request, and find the client sends a contain IP address, server IP address, gateway of information such as his frame. Finally, according to the client may TFTP server to through special frame download start image files, modeled as disk boot.
FC sep
This RFC describe a IP/UDP guide agreement (the BOOTP), allow a no disk client found himself, the server's IP address of host addresses, and into a named file into memory and run. Guide operation have two component phases.
The first stage RFC description: 'distribution address and choose guide file'.
In gaining address and filename information, came into the lead after the second phase: file transfer.
File transfer generally use TFTP agreement, because two phases are lives in client PROM.
But the BOOTP can also with other agreements such as SFTP or FTP work together.
We suggest that client PROM software provides a complete without the user interaction guide ways.
This is a kind of unattended on electric start way.
Must provide a mechanism to let users manual provide address and filename information bypass the BOOTP protocol enter directly file transfer stage.
If to provide a variable storage, we suggest there to save Settings to bypass the BOOTP protocol until these Settings lead to file transfer phase failure.
If a cache of information failure, guide fall back into the first phase and use the BOOTP. 

Users can recommend the most fat consumption 10 big movement

Women always are constantly thinking about losing weight, below is recognized as one of the ten kinds of netizen the most effective fat reducing movement, collected, and make reference for everybody.

Car Navigation

Navigation is to use on-board GPS (global positioning system) in cooperation with electronic map, it can be convenient and accurately tell drivers the shortest or to the destination path, is the fastest drivers good assistant.
The car's navigation profile:
With GPS satellite positioning system function, let you when driving a car anytime know you exactly. The car's navigation to its automatic voice navigation, the best path search and other function let you all shortcuts and high-speed motorcade, integrated office, entertainment functions allow you to easily driving, efficient trip! General navigation functions are DVD players, radio reception, bt, touch screen and matching function, intelligent trajectory backing up, tire pressure testing function, virtual six disc, backstage control function!
The car's navigation system functions:
Function module detailed instructions
GPS navigation satellite accurate positioning, best path search, automatic audio.
Navigation mode a variety of purpose input, five or more path retrieval customization mode, site setting mode, map location mode.
The national map with the national electronic map, provide thousands of city support, navigation map of latest more precise let you high-speed motorcade.
Path planning and destination and provide st, set the path planning and inevitably function.
Voice prompt kind real voice prompt, automatically broadcast driving road name.
Music appreciation audio-visual enjoy, relieve fatigue.
File management powerful resource management functions.
The car's navigation GPS positioning principle:
GPS is composed by 24 star, it is located at work from satellite ground 20200km above, evenly distributed in six rail surface (each track surface 4 star), orbit for 55 ° Angle. In addition, there are 4 star orbiting active backup satellite. Satellite distribution in making global anyplace, any time can be observed to 4 star above the satellite, and can maintain good positioning decoding the geometry precision of images. This provides in time in the continuous global navigation capabilities. Since the satellite in the position of GPS observations accurately knowable, we can get satellite receiver distance, use to the distance formula 3d coordinate, using three moons, can a formula of 3, work out observation position (X, Y, Z). Considering the satellite clock and receiver clock errors between, actually has four unknown, X, Y, Z and clock is poor, so need to introduce the first 4 satellite, form four equations solution, thus obtains the observation and elevation latitude and longitude.
In fact, receiver can often lock 4 star above, at this moment, the satellite receiver can press satellite constellation distribution into several small groups, and four star, then through the algorithm selected a group of used minimum error, so as to improve the precision positioning.
Since the satellite orbit, satellite clock exist errors, atmospheric troposphere, ionosphere to signal, and the influence of SA protection for civil policy that makes GPS positioning accuracy of just 100 meters. In order to improve the positioning accuracy, widespread use of the differential GPS (DGPS) technology, set benchmark stand (difference), GPS observation platform using the known precise coordinates with the benchmark stand comparison, observations, and concluded that a fixed number, and foreign release. After receiving this fixed number of receivers, and own observation value is used in the comparison, expunction most error, get a comparative accurate position. Experiments show that, using differential GPS positioning accuracy could be enhanced to 5 meters.
On-board navigation constitute
Vehicle navigation system mainly consists of navigation host and navigation display terminals two parts. The built-in GPS antennas receives from around the earth in the 24 star GPS satellite at least three single message of data information, thus determine automobile current position. Navigation host through GPS satellite signal definite position coordinates and electronic map data match, then can determine the accurate car in electronic map location.
On this basis, will realize turn-by-turn navigation, route recommend, information query, played AV/TV functions. Drivers simply by watching on the display screen, listen to audio, manipulate the remote control to achieve the above the hand function, and can be easily drive.
The GPS navigation system consists of two parts:
Part of the installation in the car's GPS receiver and display equipment composition; Another part of the computer control center, two parts by positioning satellites contact.
Computer control center is by the vehicle management department authorized and formed, it is responsible for monitoring at the designated observation within the jurisdiction of the dynamic and car traffic conditions, so the whole car navigation system there are at least two big functions: one is car trace monitoring function, as long as will have coding GPS receivers installed in the car, the car whether driving to everywhere of the computer control center by electronic map indicates that its location position; Another is the driving guide function, owner of each areas can be stored in electronic drawing traffic routes floppy disk, as long as in the car insert a floppy disk, receiving device screen will immediately showed the region's position and the current traffic condition, can input destination, programmed the best driving route, and the computer control center can accept the instructions, choose automobile driving route and direction. 

Network Storage

IPVS network storage based on the Internet for the recent rise of storage ways IP address to access. Simple working principle for IPVS network video storage device: the Internet, on through the terminal equipment IP address, and thus for the terminal equipment visit video and other various information storage. IPVS network video storage using disk array (disk array of Redundant Arrays as RAID: Disks, RAID) simultaneously the way to protect data storage, in traditional NAS storage system provides more reliable based on the data protection, and enhance the equipment visit flexibility. IPVS network storage of data is stored on safety protection, at the same time provide very convenient expansion strategy.
Realization way
SAN Storage Area of Storage Area Network) through a connected to a group of optical fiber channel computer. In this network provides many host links, but not through standard network topology.
SAN focus on specific problems, enterprise-class storage is mainly used for large storage working environment. The current enterprise storage solutions of the problems encountered by two roots are: data and application system generated by combining the structural limits, and currently small computer systems interface (SCSI) standard restrictions. Most analysts think SAN is the future of enterprise-level storage solution, because the SAN facilitate integration, can improve the data availability and network performance, but also can reduce the storage management assignments.
Development trend
A SAN is currently people accepted most potential storage technology solutions and the development trend of future SAN will be open, intelligent and integration. NAS is currently the fastest growing a storage technology, however, the trend of the development of both concerned, in application-layer face SAN and NAS will realize full integration. Can say, NAS and SAN technology has become the mainstream of the current data backup technology, the key lies in how to fully developed on the basis of the all-round, multi-level and data backup system in distributed network environment, through professional data storage management software, combined with the corresponding hardware and storage devices on the network, centralized data backup, thus realize automatic backup, filing, data hierarchical storage and disaster recovery, and other functions.
The application of network storage
The application of network storage network information technology from birth to say the day began, application field along with the development of information technology and continuously increased, but the big classification includes the following four categories:
The ISP's full name is the InternetServiceProvider that Internet service providers;
ICP is Internet Provider by the abbreviations, meaning "Internet Content providers", which provides Internet information search, sorting processing services. Such as sina, sohu, etc.
ASP is the abbreviation of apply Service Provider, meaning "network Application Service providers", mainly for enterprises and institutions in the informatization construction, develop e-commerce based on the Application of Internet provide various services.
The Storage Provider NSPS is a reviatio, meaning "Network Storage service providers", mainly for enterprises, individual provide a Network Storage and transmission, processing service businesses, such as DBank data bank, IDC enterprise. 

No equipment TRD family fitness

TRD families in the U.S. currently popular doing aerobics. Because this without equipment, venues, doing aerobics easy, effective, thus deeply the crowd welcomed. Now that the United States has about 880 already put the primary, middle doing aerobics listed as physical exercise compulsory project.
Basic action
A, huddled up sit (or sit-ups)
Unit time curled up sit since the quantity is abdominal muscle flexibility endurance quality symbol. Service muscular, can avoid the pain, spinal cord keep good body posture. Practice is, supine, his arms across his chest, legs clasp from the hip, heel knees up 30 to 40 centimeters, tiptoe hook furniture along the bottom. Lift to sit, until the body as close to the thigh, head forward. In 1 minute required repeated incessantly try.
Second, push-ups
Push-ups can exercise the arms and shoulders and chest muscles and strength and endurance. These muscles, and helps keep the coordinated development of good asanas and avoid including chest, suspicious back. Women and children under the age of 10 can double genu touchdown and leg cocked up doing, requirements, ShuangZhang flat in his keep, palm maintains the ground below the shoulder from and shoulder are the same as wide. Then do flexor arm props up exercises. Men and 10 years old, but should be same children action palms and tiptoe hold to, trunk keep straight.
Three, flat sat forward
This movement can exercise vertebrae, and legs and hips and flexibility. Good flexibility helps avoid vertebra and lumbar back pain at the bottom leg injury. Practice is, legs and approach is sitting on the ground, former horizontally, foot against the wall. Hands forward, trying to touch the wall. Note, knee shall not bending, forcibly not vastly, muscle as relax. Lasts for 5 seconds.
Four, three minutes jumping
Mainly is to exercise the heart. Jumping method is, the ground put only small wooden bench or a bundle of newspapers, highly about 30 centimeters, right to left foot pedal stool on his left foot step stool, alternating on land,. Do Chuan 24 times per minute, average 2-3 seconds once (alternate) action.
Operating procedures
A, preparation activities (5-10 minutes)
1, with a light steps go 3 minutes. 2, continue to walk 2 minutes above, straightening add some action; Palm, arms raised the fingers crossed, with arms swinging drive torso; Not swing arms side to lift (similar to bird flight); Upper left, right arms drive twisting; Big arms and hands shaking violently.
Second, heart exercise (10-30 minutes)
1, 3 times per week to make each aerobic exercise, 10-30 minutes, according to the length of time of oneself body state discretionary. Exercise methods like jogging, three minutes jumping, etc. 2, many people like to play bowling and golf or go out for a walk, these sports can consume calories, and stored inside body won't make the heart burden, also is the good way to train my heart. Adults quiet when heart minutely jumpy 60-80. A 40-year-old man, if the heart is average minutely jumpy 125 times, that every weeks 3 times aerobic exercise must be at least 20 minutes and every time. 3, most people like to use the long-distance running, swimming, skip, cycling, dancing, boating, tennis etc, this also is aerobics good way to improve cardiac function, it can be emulated.
Exercise begins, with low rates. Finally reached 30 minutes. In order to master heart rate, after 3 minutes in quick breathing just a moment, with 15 seconds Chuan remember the pulse frequency, calculate 1 minute palpitant frequency, continue to exercise. If detected numerical too low, it should be accelerated motion; If it is too high, should be appropriately reduced movement speed.
Three, upper body movement (5 minutes)
In order to improve the abdomen, shoulders and upper limb muscle performance, should press the following methods exercise. 1, huddled up sitting. 2, push-ups. 3, hind admire, two arms folded across his chest. His hind admire, make back and ground a 45-degree Angle. Maintaining a pose 3 seconds or longer until muscles ache, trembling, reduction, repeat again. 4, flexor arm, two legs slightly apart, arms in each hand, one raises hold 1 pound of objects, palms up. Then simultaneously to the flexor arm, hand in the shoulder, touch repeated objects.
The four movements not finished a to do another, can put each action dismantled, composition, as if ten minor cycle crouching sit since four times, four times push-ups, 4 times hind admire, four times for a cycle bowed arm. Minor cycle of exercise is gradually increased from every again through every 8 times above. Exercise a week to gradually from 1 times. Three times a week
The number of each movement in the minor cycle death also don't provisions. For example, beginning stage May 3 huddled up the seat and push-ups also don't, then you might as well put down after the number of flexor arms upward and appropriately increase to supplement.
Four, relaxation exercises (5 minutes)
In order to prevent muscle and nervous because of excessive tension and appear sore, dizzy wait for a phenomenon, the end of practice should do relaxation exercises. 1, take 2 minutes, shaking his arms, can alternate may relax. 2, with three minutes to do the following flexible practice. Flexor sit embrace crus, different is in full root, right leg bowed with her hands groin, then close to the upper left crus, delicious suppression as next volts. With a few seconds left, change after doing the same action. Three, stretch the shoulder, arms, as far as possible extension smooth lift. 4, back hook hand, arm from shoulder flexor, two finger after hook, keep in back photograph for a while. Alternating control again direction arm do the same action.
See the introduction, family TRD doing aerobics perhaps you intend to start tomorrow morning, then try to practise very well, but must not be too hasty, must be gradual, try to your best, still persevered.
