During the water vapor diffusion stage, the range of water evaporation loss increases with the increase of gravel content.

在蒸发的水汽扩散阶段，砾石含量越多，蒸发损失量随时间波动幅度越大。

The water vapor evaporation and condensation at the bubble wall and the water vapor diffusion versus the noble gas inside the bubble are also considered.

同时考虑了水蒸气在气泡壁上的凝结与蒸发以及水蒸气在气泡内相对惰性气体的质量扩散。

When various manipulations disturb the thermal boundary layer inside or the condensate film and gas-vapor diffusion layer outside, the heat transfer effect will be better or be worse off.

各种操作条件只有影响到管程的温度边界层或壳程的冷凝液膜层和气-汽扩散层，才能强化或恶化传热过程。
