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 principle of resistance measurement is adopted to determine saturation, a micro-probe is selected finally by evaluating multiple materials and samples.
采用电阻测量原理，确定了饱和度测量方法；考察了多种材料和样品，最终选定了一种微型探针。

On the grounds of the pinch-off voltage, the cut-off point of variable resistance area and saturation area can be fixed, so the field effect tube can reliably work in the saturation area.
