Lower temperatures will reduce surface evaporation of constituents minimizing the capillary action that draws constituents to the surface where they would be volatilized.
较低的温度可减少成分的表面蒸发，使那种将成分吸到表面并挥发掉的毛细管现象降到最小。

Based on a review of existing micropumps, in the work systematic studies were conducted on PDMS pneumatic micropumps, micropumps based on evaporation and absorbion, micropumps based on capillary and .
This paper introduced both mechanisms of dewatering and evaporation, and filtering. The main drives for binder migration were discussed in detail, which are capillary force and penetration pressure.
