到底哪个之精神上的，哪个指物理上的？为什么每个人回答都不同？？？？？、
两个词都可以用在精神上，也都可以用在物理上。你可以自己看看词典的解释来证实： http://www.google.com/dictionary?langpair=zh-CN%7Cen&q=stress&hl=en&aq=f http://www.google.com/dictionary?langpair=en%7Czh-CN&q=pressure&hl=en&aq=f 在物理学上，stress 翻译成“应力”，特别指一种使材料变形的压力，而 pressure 则翻译成“压强”，一般指“垂直作用在物体单位面积上的压力的值”。 应用在精神层面，stress 的着重点是主体本身的感受（使主体精神状态“变形”的力），比较指主观感受。而 pressure 一般是指环境的压力，就像大气一样压得人喘不过气来的那种压力，比较指客观环境。一般心理学上说的“精神压力”用 stress。对别人施加“压力”，只能用 pressure。
