saturation vapor pressure

基本解釋

The influence of atmosphere saturation vapor pressure deficient to sap flow was smaller.
儅樹內(nèi)的壓力大於大氣壓力的時候，樹液開始流出。
On the other hand, in nighttime, the transpiration mainly depend on temperature , windspeed, and saturation vapor pressure, etc.
作物夜晚的蒸騰變化主要受氣溫、風(fēng)速、空氣飽和差等因素的影響。
That is different from the elevation above sea level atmospheric pressure and water temperature at 20 degrees centigrade higher than the saturation vapor pressure.
即不同海拔高程処的大氣壓力和高於20攝氏度水溫時的飽和蒸汽壓力。
