stress和pressure有什么区别(意思上及用法上)
有区别。stress 和 pressure 在表达压力的意思时有词义的区别。
stress 和 pressure 在英汉词典里的注释都是“压力”,但在实际应用中这两个并不是同义词。它们最大的词义差别是“压力”的形成源。stress 的压力产生于自身,而 pressure 指来自外部的压力。物理学在使用这两个词上就分得很清楚,物质材料因外力作用而产生变形,外来的力量称作 pressure,而材料内部的变化,无论是拉扯还是挤压,称作 stress。例:
A body collapses if pressure exceeds stress. Though stress, or internal resistance is due to external forces, or pressure, it needs to be equal to it. (当外部压力大于材料本身的张力时,物体会垮塌。尽管张力(内部抗压力)是因为外力(外部压力)而产生,但这两个力需相等。)
在引申词义上,stress 和 pressure 也同样有词义和使用的差别。stress 用于精神压力。尽管这种压力可能因外部事物造成的,但却是自身内部的压力。pressure 则是造成 stress 的外部压力,如工作压力,人际关系压力,经济压力等等。这些都有可能造成人的精神压力,即 stress。例:
Stress may be caused by the pressures of examinations or work deadlines. (精神压力可能是因考试或工作期限的压力所造成的。)
stress和pressure的区别
1、压力的侧重点不同stress侧重指承受外来的压力,也指由于某种原因而引起的心理、生理或情绪上的紧张。
pressure在科学上,指单位面积上所受到的压力。用于引申时,指某事物所产生的压力或影响力等。
2、动词的意思不同pressure动词是施压的意思,stress是强调的意思,并且名词还有重音的意思。
3、从句的不同stress作为动词可以引导从句。
