解析 specific weight = weight/volume就是比重,单位是 (N/m^3或者 lb/ft^3)而gravity 指的是地心引力,所以不是用力来算的,而是用密度,所以,specific gravity=density /density of water @4 摄氏度,可翻译为相对密度,,没有单位(无量纲)。 结果一 题目 specific weight与 specific gravity的区别 答案 首先,w...

举例:The density ratio of the sample to water is 1.5. “specific weight”:虽然这个词不如“specific gravity”常用,但在一些特定领域,比如地质学,也可能用来指比重。 举例:The specific weight of the rock sample was measured to be 2.7.
