principle 和mechanism做原理讲的时候区别是什么

首先，我们看一下当principle原理来讲时的英文含义
牛津高阶：a law, a rule or a theory that sth is based on
柯林斯：The principles of a particular theory or philosophy are its basic rules or laws.

然后我们再来看一下mechanism
牛津高阶：a method or a system for achieving sth
a system of parts in a living thing that together perform a particular function
柯林斯：A mechanism is a special way of getting something done within a particular system
A mechanism is a part of your behaviour that is automatic and that helps you to survive or to cope with a difficult situation.

可以说principle是我们做事的指导原则，是核心思想，是理念；
而mechanism则是我们为完成目标，解决问题题而采用的实际方法
作为老板，领袖，更多的要考虑principle
而工程师们则满脑子的mechanism

mechanism侧重机械原理

严格来说，“mechanism”没有“原理”的含义，
其相关含义为“方式、方法”，
中文对应的“机理”是被引申出来的。
