内膜渗透性 inner membrane permeability
外层渗透性视网膜病变 external ex-udative retinopathy
设计一种适合的膜非常困难：一方面要足够坚韧，以承受压力；但同时还要有渗透性，而且只能透水，不能透盐。
Devising a suitable membrane-tough enough to withstand the pressure while remaining permeable to water but not to salt-is harder than it sounds.
试验结果证实了页岩与水基流体之间存在着渗透现象，且页岩是一个非理想性的半透膜。
Therefore, osmotic phenomenon exists in the system of shale and water based fluid, but shale is a non-perfect semipermeable membrane.
在渗透胁迫下能维持较高的相对含水量（RWC）和较高的保护酶（SOD）活性，质膜相对透性较小，膜伤害较轻。
Under osmotic stress, It could maintain a higher RWC level and a higher activity of superoxide dismutase(SOD), and lessen membrane injury.
