on-air testing

基本解釋

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(diào)器性能測試平臺的實際運用出發(fā)，推導(dǎo)出了空調(diào)器風(fēng)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.
試驗是在矩形試驗件上進行的，模擬了燃燒室流動狀態(tài)。
Jet-lag trials might involve laboratory simulations, but we also need 'the real thing, ' which means testing pharmacological treatments on long-haul air travel.
時差綜合癥的試驗需要實驗室模擬，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于長期空中旅行（的人）的藥效。
