应用于fluent两相流相变，定义气液两项之间质量传递。(Used in fluent two-phase flow phase transition, the definition of gas-liquid between the two mass transfer.)

c++编写的质量源项控制传质过程，fluent模拟计算可加载，过程强化行业可应用(Mass transfer process is controlled by quality source term written in C + +, fluent simulation can be loaded, and process strengthening industry can be applied)
