ambient wind velocity 中文意思是什麼
ambient wind velocity
解釋
環境風速-
Not satisfied by measuring ambient temperature with an obsolete system, ameri - cans invented the wind - chill factor, which combines degrees fahrenheit with air velocity to create a num - ber that ' s much more impressive
美國人不滿足於用過時的系統來衡量溫度，因此發明了風寒因素，即把華氏度與空氣速度結合在一起，所得數字給人的印象要深刻得多。 -
Experimental constants include : ambient temperature 291k ~ 301k, rh 15 % ~ 21. 2 %, wind velocity 3. 2m / s at the nozzle position and horizontal to the spray fan, others are same as the fore experiment. the tendency of the two experiments results is consistent with the tendency from simulation. that indicate the improved shield spray is better than the original shield spray in reducing spray drift, and also more better than conventional spray without shield
風洞試驗參數：噴霧藥液為含1 bsf的水溶液，風速1 . 4m s ，風向垂直於噴霧扇面，溫度281k 288k ，相對濕度rh9 20 ；室內試驗參數：噴霧藥液為含2 bsf的水溶液，噴頭處風速為3 . 2m s ，風向平行於噴霧扇面，溫度291k 301k ，相對濕度rh15 21 . 2 ；分別在噴頭下風向噴幅外的空中和地面布點收集飄失和飄移沉積的霧滴量，作為評價減少霧滴飄失效果的指標：試驗結果表明：改進后的罩蓋噴霧減少霧滴飄失的效果好於雙圓弧未開口罩蓋噴霧，常規無罩蓋噴霧的霧滴飄失量大於開口罩蓋噴霧。 -
The captured droplets weight is regarded as evaluating indicator. experimental constants include : ambient temperature 281 - 288k, rh 9 % ~ 20 %, wind velocity 1. 4m / s and vertical to the spray fan
風洞和室內試驗比較了結構改進前後的罩蓋噴霧減少霧滴飄失的效果，並和常規無罩蓋噴霧對比。
