Water Flow Resistance

All the phenomena show: water flow resistance is the important prerequisite to cause transpiration fluctuation, and the latter can be the result of stomatal oscillation.

这些现象说明，水流阻力是蒸腾波动产生的重要前提条件，而蒸腾波动则可能是气孔开合波动的直接结果。

The flow resistance of foam is affected by those parameters such as surfactant concentration, oil saturation, temperature, permeability, water and gas phase velocity, etc.

泡沫的流动阻力受泡沫剂浓度、温度、油饱和度、渗透率以及水相和气相达西流速的影响。

The engineering thermal calculation, the calculations of different operating conditions, of the resistance of water flow and vapor flow, and of the air leak amount were made.
