Conservation of mass, momentum, and energy are used to solve for the liquid film thickness, velocity, and temperature.
通过求解质量守恒、动量守恒、能量守恒方程，获得液膜厚度、速度与温度等参数。

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。

There is a very positive correlation between the task of conservation of external volume and the task of the mass of liquid keeping in the same in the thermometer, as it is heated.
