摘要
讨论质量与重量、体积与容积、体积质量与容重、含量与百分率等物理量的含义与区别。指出现在所说的与力无关的重量均应改为质量,体积与容积2个概念的主体不同,容重、比重均应统一为体积质量,含量应分情况改为质量分数、体积分数等。
Meaning and distinguish of several units in physical quantity,including mass and weight,volume and cubage,volumic mass and bulk weight,content and percent,volume fraction and volume concentration were discussed.It indicated that all units about weight irrelevant with power should be changed into mass;the subject of volumic mass and cubage are different,bulk weight and specific gravity should be volumic mass;nature should be judged when content was used,volume fraction is difference from volume concentration,and volume concentration will be replaced by volume fraction.
