对蒸发器的流动和传热现象进行了可视化实验，结果表明，蒸发器内的压力波动与肋顶面处产生的蒸汽逸出状况密切相关；在实验过程中，在毛细芯的背面始终未出现蒸汽。

Evaporation quantum of liquid is expressed as mass source for vapor in vapor mass conservation equation, while it is dealt with mass sink for itself.

在建立多孔介质各相质量守恒方程时，液体蒸发量相对于蒸汽相而言为质量源，对液相本身而言为质量汇。

For the FA, the results indicated that the VPD calculation using mean of 24 hourly temperature values as saturation vapor pressure, and wet-bulb depression as actual vapor pressure yielded the lowest error, the least range, and the most frequency with the highest WI. These outcomes were as well as the SIA with the lowest EMSE, R^2 higher than 0.99 and the highest CE.

分析结果显示，以频率分析法而言，各地农业气候分区均呈现，VPD计算式以24个时温度日平均为饱和蒸汽压力，与湿球下陷量为实际蒸汽压力，具误差最少、全距最小、出现频率最多及最高权重指数，性能表现最佳，这样的结果，对照统计指标法之检测评估，同样具最低RMSE、R^2值0.99以上及最大CE，性能表现优於其他所有VPD计算式，两者，结果一致。

Two problems are encountered in a vacuum distillation. The volume of vapor formed from a given amount of liquid is pressure dependent; i.e., the volume of vapor formed from one drop of liquid will be about 30 times as great at 25 torr as it was at 760 torr.

在真空蒸馏中会遇到两个问题：己知量的液体所形成的蒸气体积是依赖於其气压的；例如一滴液体在25陶尔时所形成的蒸气的体积是它在760陶尔时所形成的体积的30倍。

所用的测定装置具有汽相循环，体积自动补偿及汽液相样连续在线分析之优点，所得数据较可靠。

It is foaming in layer gutters when megatemperature frother and nitrogen gas are filling in. HS foam film blanks off high permeability zone or high capacity channel, which represses vapor going into high permeable bed and makes it turning to low ones. Wherefore the displacement volume includes and vapor sweep area expands and reservoir development improves.

通过加入高温泡沫剂和氮气，在地层孔道中产生泡沫，高强度的泡沫膜封堵高渗透层或大孔道，有效地抑制蒸汽进入高渗层、高渗段、高渗带并转向低渗层、低渗段、低渗带等未驱替带，增加驱替体积，提高蒸汽波及面积，改善油藏开发效果。

When air padding is allowed and appropriate, it is imperative that clean, oil-free, cooled, dry compressed air be introduced into the vapor space through its vapor valve to transfer the liquid.

压缩空气通过蒸气阀门进入蒸气空间，来转移液体。
