渗透压差

释药孔孔径和包衣工艺对药物释放无影响。对其释药机制进行探讨，证明TROROS的释药动力为膜内外的渗透压差。

The release mechanism is discussed and it is indicated that the release rate of TR from OROS device is driven by the osmotic pressure difference across the membrane .

从理论和数值模拟上证明了渗流速度不仅仅和渗透压差有关，还和试件的围压与端部的水压有关，其根本原因就是围压和端部水压使得裂隙的开度发生了变化。

Prove that the flow velocity not only depends on the osmotic pressure difference , it also depends on the confining pressure and the hydraulic pressure of the specimen . The fundamental reason is the confining pressure and the hydraulic pressure change the fissures opening .

结论：血浆渗透压差的监测可有效地预防急性肾功能衰竭的发生。

Conclusion : Monitoring the serum osmolality can prevent ARF .

试验发现随着渗透压差的增大，渗透系数增大。

Results suggest that hydraulic conductivity increased with the increase of osmotic pressure .

在低于最适生长温度时，耗氧率可以反映出机体内外渗透压差大小与能量需求的关系；

Only at lower temperature could Oxygen Consumption Rate reflect the relationship between osmotic difference and energy requirement .

其次，通过模拟计算更系统的研究不同渗透压差条件下岩石试件的渗流破坏规律。

Secondly , more system of study on the law of seepage failure under different osmotic pressure conditions through simulation calculation .

研究表明内外水相间的渗透压差会引起水在两相间的扩散，并且同时促进了聚并的发生，显著地影响多重乳液的形貌和稳定性，所以有必要对渗透压下的水扩散进行控制。

Experimental studies indicate that the coalescence under osmotic pressure is obvious and the control of water transport is needed so as to keep the stability of multiple emulsions .

这个现象提供了一个实现载药W/O/W多重乳液体系控制释放的手段，即通过调节内外水相间的渗透压差来控制液膜聚并速度，最终实现药物的控制释放。

The osmosis pressure almost has no effect on the morphology but on the coalescence . This phenomenon provides a way of controlling the release of drug from W / O / W multiple emulsions .
