relation 和association有什么区别

relation和 association在表示两者（人 ，国家 ，ETC）关系这个意思上面，如果没有什么感情的意思是可以混用的。比如中美关系，两者都可以

和FRIEND，FRIENDSHIPMEMBER，MEMBERSHIP的关系类似，但要复杂一点，主要原因是在于RELATION本来就是抽象的东西。FRIENDSHIP可以看成FRIEND之间的一种关系。RELATIONSHIP也可以看成RELATION的关系，就是关系的关系。

比如：

THE RELATIONSHIP BETWEEN ME AND MY FATHER，我和父亲的父子关系上的感情层面的关系，可以用好或者不好来形容

THE RELATION BETWEEN ME AND THIS MAN IS SON AND FATHER。表示一种客观存在的联系，就是父子联系。就没有好和不好的概念，因为它是客观存在的关系。

因此，RELATIONSHIP可以带有感情的意思，比如用来指一段恋情。
