detach和dispatch作派遣讲如何区别？

区分英语词汇词义时，一定不要仅看“英汉”而望文生义。如这两个词，根据韦氏词典的解释，区别点一目了然：
detach
: to separate (something) from something larger
: to separate (yourself) from someone or something

dispatch
: to send (someone or something) quickly to a particular place for a particular purpose
: to defeat (a person or team) in a game, contest, etc.
: to kill (a person or animal) quickly

很显然，同为表达汉语的“派遣”之意时，detach强调的是“separate ...from”,即从一个整体中的“分离”感；而dispatch则强调的是“去执行”感，不含有更不强调“脱离”意味。
