每个大成年树木就如同一个巨大的水泵，通过其叶或针的蒸发，将成百万加仑的水回放到大气中去。

Applying frequency governor to bottom pump of evaporation tower and feed pump of furnace, the result showed that it is the effective way to improve the automatic level in clay unit.
The interlaced heat pump flow has a total temperature difference that is lower than other heat pump flows and can be applied to the low - temperature evaporation for the heat - sensitive materials.
