A machine equipped with a semipermeable membrane and used for performing dialysis. 渗析器配备有半透膜并用来进行渗析的机器
When separated by a semipermeable membrane (e.g. a cell membrane) water moves by osmosis into the hypertonic solution from the hypotonic solution. 当用半透膜（如细胞膜）将两种溶液隔开，水分就会在渗透压的作用下从低渗一侧向高渗溶液流动。
Seawater is forced through a semipermeable membrane that separates salt from water. 用半透膜将海水里面的水分和盐分分开。
Desalination is carried out by simply lowering into the ocean a long, hollow pipe capped at the lower end by a semipermeable membrane. 用一根长空心尼龙管插入海水里，并用半透膜封住较低的一端来进行海水淡化。
Diffusion of fluid through a semipermeable membrane until there is an equal concentration of fluid on both sides of the membrane. 渗透:液体通过一个半透膜进行的扩散,直到膜两边液体的浓度相同为止。
