It is necessary to include as a heat source in the thermodynamic energy equation a term which represents the time rate of release of the latentheatofcondensation of water vapor.
有必要把代表水汽凝结潜热释放的随时间变化率的一项作为热源项包括进热力学能量方程中。

The latentheatofcondensation and the water vapor don't play decisive roles in formation of the vortex, but play key roles in vortex maintenance and structure characteristics evolvement.
凝结潜热、水汽对低涡的形成不具有决定性影响，但对低涡的维持以及结构特征演变起关键作用；

Most part oflatentheatof the vapor and the sensible heat of water can be utilized several times because multi-stage falling film evaporation and condensation processes are utilized.
