They use solar power and a purification technology called reverse osmosis.

Teachers can imagine that they learned to read through osmosis when they were children.

细胞外的渗透作用会引起很大的变化。

All of these things require the movement of substances by either diffusion, osmosis, or active transport.

所有这些都需要物质通过扩散、渗透或主动运输的方式进行运动。
