After the material balance for any a mixing pool, the analytical solutions of concentration on the evaporating surface, the distillate rate and the residue rate obtained.

对每个混合池进行物料衡算，可以得到蒸发壁面上浓度的变化和轻、重馏分流量和含量解析解。

Water is part of a large cycle: it travels over land via rivers and lakes and through the oceans before evaporating \ into \ the atmosphere and eventually returning to the surface by precipitation.

水是一个大循环的一部分：水蒸发到空气中，最终又通过雨雪等降水方式回到地表，在进入这个循环之前，水通过河湖流过陆地，进入海洋。

Since the header on the evaporating heating surface adopts pre-separation structure, the effectiveness and speed of water-steam separation in the drum are improved.

同时，锅炉的蒸发受热面上集箱采用预分离结构，提高了汽包的分离效果和分离速度。

The song seems to uncoil when Finn and Barnes hit the bridge, with ideas evaporating off the surface faster than they can be spotted, let alone captured.
