  重采樣，是從高分別率向低分辨率采樣好嗎？

  記得采樣時(shí)，信息會(huì)丟失。但是已經(jīng)記不清：是向高分辨率采樣信息損失大呢？還是向低分辨率采樣信息損失大呢？記得以前老師講過(guò)這樣一個(gè)問(wèn)題，但是現(xiàn)在患糊涂了。... 記得采樣時(shí)，信息會(huì)丟失。但是已經(jīng)記不清：是向高分辨率采樣信息損失大呢？還是向低分辨率采樣信息損失大呢？記得以前老師講過(guò)這樣一個(gè)問(wèn)題，但是現(xiàn)在患糊涂了。 展開(kāi)

Top 10 Take Aways for Air Sampling. 1. There are two principle means of monitoring the microbiological population of the air ? passive monitoring ? active sampling 2. Active monitoring requires the use of a microbiological air sampler to physically draw a known volume of air over， or through， a particle collection device. 3. The most important sources of contamination in any manufacturing operation are air， people， raw materials and water. 4. Passive monitoring is usually done using ‘settle plates’. 5. There are two types of active monitoring devices ? Impingers ? Impactors 6. It is essential that air samplers are properly validated and regularly calibrated to ensure accuracy. 7. The choice of sampling method is application dependent， according to ISO 14698-1， and must take into consideration: ? appropriate flow rate impact velocity ? collection accuracy and efficiency ? effect of the sampling method on the surrounding environment 8. Choice of monitoring locations should be based upon a documented risk assessment. 9. The flow rate of the sampler pump or fan should be properly calibrated and validated against a certified flow meter. 10. Airborne bacterial and fungal cells and spores may be present in droplets as “bio-aerosols”， as very small individual particles that stay suspended for long periods， or as larger clumps and aggregates that settle rapidly onto surfaces. 展開(kāi)
