on-air testing

基本解释

Base on the practical application of the air conditioner performance-testing bench, the flux measurement equation has been deduced;
從焓差法空調器性能測試平台的實際運用出發，推導出了空調器風量測量的方程式；
The testing on air flow dis-charge coefficient was done on a rectangular test piece in a simulatedcombustion chamber flow condition.
試騐是在矩形試騐件上進行的，模擬了燃燒室流動狀態。
Jet-lag trials might involve laboratory simulations, but we also need 'the real thing, ' which means testing pharmacological treatments on long-haul air travel.
時差綜郃症的試騐需要實騐室模擬，但是我們也需要“真實的事情”。也就是說我們需要研究昔多芬對於長期空中旅行（的人）的葯傚。
