摘　　要：对非饱和带水 气二相流动的关键参数确定 ,尤其是二相流动中气相参数确定的实验方法进行了探索 ,得出了相应的参数结果 ,建立了气压自动采集系统 ,为进一步的非饱和带水气二相流动的实验模拟与数值模拟提供了参数依据。The algorithms of key parameters identification for two-phase flow in unsaturated zone are studied, especially the experimental method of air-phase parameter identification is approached, and the corresponding parameters are obtained. The auto-monitoring and data collecting system for air pressure is set up. The parameters obtained can serve as basis for further experimental simulation and modeling of two-phase flow.
