Selection of high thermal conductivity of the heat sink material is very helpful to improve the efficiency of heat conduction.

散热片选用较高导热系数的材料对提高热传导效率很有帮助。

Mantle material can sink at a plate boundary, and then flow back upward farther away, pushing on the crust - a process called small scale convection.

地幔，这种物质可以在板块边界处下沉，然后向上回流到较远的地方，再与地壳相碰撞——这个过程被称为小规模的对流。

Lake sediment nevertheless constitutes an important "carbon sink," serving to store - sometimes for a very long time - a significant portion of the carbon-containing material that does not decompose.

然而湖泊沉积物又是一个重要的“碳汇”，用来存储-有时存储很长的时间-相当大部分不能分解的含碳物质。

Lakes also act as a sink for water and material inputs from diverse sources from their surrounding drainage basins.
