Therefore, osmotic phenomenon exists in the system of shale and water based fluid, but shale is a non-perfect semipermeable membrane.
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。
The membrane cannot maintain the osmotic balance of nutrients (sugar) inside the yeast cell and the by-products (alcohol) outside.
渗透膜不能保持营养平衡(制糖)酵母细胞内的副产品(乙醇)之外。
Methods Core tablets containing osmotic active agent were prepared by direct compression and spray coated with swelling layer and semipermeable membrane subsequently.
方法粉末直接压片法制备含渗透活性物质的片芯，滚转包衣锅法分别包溶胀层和控释衣层。
