semi-permeable

基本解释

Pressurized water is passed over a semi-permeable membrane which allows the passage of water molecules while rejecting the passage of larger ions.
受壓水經過半滲透膜，使得水分子能通過，而更大的離子卻不會通過。
The conventional method involves boiling and then distilling water. An alternative works by reverse osmosis, in which water is forced through a semi-permeable membrane.
傳統技術用的是蒸餾，新興的替代技術是通過迫使鹹水通過一個反滲透薄膜以達到過濾。
This involves tapping both freshwater and seawater at the mouths of Norway’s many rivers and fjords, and diverting it to tanks on either side of a semi-permeable membrane.
這種技術的操作原理是：在挪威衆多的河流與峽灣口抽取淡水與海水，然後將這些水資源輸轉到半透膜任意一邊的儲水庫中。
