The research results are highly reproducible owing to the repeatable micro-model technique.(2) Quantifying the Kr-S-P curves in two-phase flow. The validity and adaptability of multi-phase curves are verified using micro-model testing bed tailored to adequate scale of pores. Results obtained from the P-S micro-model tests generally agree with the threshold values of displacement mechanism offered by researchers using geometric shapes. The hysteresis of .experimental Kr-S curves of numerous two-phase flows are depicted in terms of connectivity and humidification. The P-S and Kr-S curves of two-phase flow are well-derived in conjunction with micro-model test results and empirical van Genuchten model. For the curve expressing the relation between saturation and capillary pressure, experimental results of water-air flow system corresponds to the theoretical data.

2二相流体对微模型实验之Kr-S-P关系：包括以孔颈尺寸比例组成微模型板实验平台去证实多相流流动主要特性曲线正确性与适用性；验证水和空气二相流之P-S微模型实验，与前人以几何形状所推估出来的置换机制门槛值大致吻合；以连通性及润湿性等解释多组二相流体对Kr-S曲线实验之迟滞现象；以微模型实验结果配合van Genuchten特性曲线经验式互推估二相流体对之P-S与Kr-S 曲线，推估结果良好；以比例原则推估多组二相流体於毛细压力-饱和度曲线的结果，显示在水和空气二相流体对为参考流体对时，推估其他组流体对吻合度最佳。

Dynamic pressure is a function of velocity and air density, which in turn is dependant upon altitude and temperature.

动态压力是一个功能的速度和空气密度，而这又是取决于海拔高度和温度。

Further, a vapor discharge opening and a vapor discharge valve mechanism are provided in that part of the pump channel which is between the air discharge opening and an inlet section of the pump channel. The vapor discharge valve mechanism is closed in the start of the pump, preventing negative pressure at a fuel suction opening from being reduced, and the mechanism is opened in the start of fuel pressurization, discharging fuel containing vapor to the outside of the pump channel.

另外，在上述空气排出口和泵流路的入口部之间的泵流路上设置蒸汽排出口，此外设置蒸汽排出阀机构，其在燃料泵启动时闭阀而防止燃料吸入口的负压降低，如果燃料加压开始则开阀，从而将含有蒸汽的燃料向泵流路的外部排出。
