逆渗透作用则是逆转这个过程。

Now reverse osmosis, it's the reverse of this natural process.

渗透作用就是有两个不同的空间，将两种不同浓度的盐溶液分开。

And osmosis is where you have two chambers that separate two levels of salt concentration.

在这种情况下，渗透作用使得鱼儿不停地失水以平衡体内外盐的浓度。

In this case, osmosis causes the fish toconstantly lose water in order to equalize salt concentration inside and outside the fish.

水通过渗透作用进入鱼儿的身体，在这一过程中，水从高浓度的地方扩散至低浓度的地方。

Water gets into a fish's body through osmosis, the process in which water diffuses from a higher to a lower concentration.

方法：采用小鼠离体皮肤作为渗透屏障，研究不同浓度氮酮对新斯的明渗透作用的影响。

METHODS:Using isolated mouse skin as permeation barrier, the influence of different concentrations of azone on percutaneous permeation of neostigmine was studied.

氮酮作为一种新型的渗透促进剂，由于能增加水或脂溶性化合物皮肤渗透作用，且无不良反应，发展成为较为理想的皮肤渗透促进剂。

As a new penetration enhancer, azone can enhance percutaneous absorption for aqueous or fatty compound but no harmfulness, so gradually become an ideal entrance of cutaneous penetration.

酒石酸及其钾盐是有渗透作用的泻剂.

Sodium potassium tartrate and tartaric acid are osmotic laxatives.

酒石酸及其钾盐是有渗透作用的泻剂。

Sodium potassium tartrate and tartaric acid are osmotic laxatives .

结论: 茶碱贴片体外经皮渗透作用较好.

Conclusion: Theophylline transdermal patch has good permeation in vitro.

方法采用两室扩散池装置，以离体大鼠腹部皮肤为渗透屏障，用预处理皮肤法考察山茶油的促渗透作用；

Methods The percutaneous penetration experiment was performed on a 2-chamber diffusion cell in vitro with the application of camellia oil to the skin as a penetration enhancer.
