inhibit和restrain,constrain有何区别？

inhibit在柯林斯字典中的解释是：
To inhibit someone from doing something means to prevent them from doing it, although they want to do it or should be able to do it.

例句： It could inhibit the poor from getting the medical care they need...

restrain
If you restrain someone, you stop them from doing what they intended or wanted to do, usually by using your physical strength.

例句：Wally gripped my arm, partly to restrain me and partly to reassure me...

constrain:
To constrain someone or something means to limit their development or force them to behave in a particular way. (FORMAL)

例句：Women are too often constrained by family commitments and by low expectations...

区别在上面的解释中很明显inhibit强调阻止人们做应该做的事，restrain强调用身体或者力量去阻止。constrain比较正式，指限制发展或强迫做某事。

inhibit抑制
eg.A substance used to kill or inhibit the growth of algae.
杀藻剂用来杀死或制止水藻生长的物质

Constrain表示力劝，强迫，常用于constrain sb. to do sth.；
eg.She trie
