【摘要】 讨论了近年来在冶金书刊中作为国际单位制推行的质量分数和传统的质量百分浓度的关系,指明了出现计算错误的可能性,并联系热力学函数的标准状态进行了分析。也提出了冶金学中使用国际单位制目前还存在的若干问题。更多还原

【Abstract】 The mass friction was recommended as a SI unit in metallurgical literature in China receutly. The relationship between the mass fraction and traditional weight percent is studied. The possibility to have calculation errors in metallurgy by using these two units is discussed with the analysis on the standard states of thermodynamic functions. Some problems existing in the application of international unit system in metallurgy are also pointed out.更多还原
