摘要
对包括编辑学界在内的科学界中至今仍有人把ppm作为单位来使用的原因进行了归纳和分析。认为4种糊涂认识是导致ppm继续存在于科学文献中的主要原因:一是对ppm的语言学缺陷问题无认识;二是对量纲一的量的性质认识有误;三是不了解习惯上将B的质量浓度单位“mg·L-1”写作ppm的特定条件;四是对国际科学界取缔ppm的要求不了解,误以为“不用ppm”的规定是中国的“土政策”。
The reasons of using 'ppm' as a unit in the scientific community are summarized and analyzed in this paper. There are four wrong opinions about 'ppm' , i.e., knowing little about the linguistics shortcomings of ' ppm ', misunderstanding the characteristics of quantities of dimension one, being unfamiliar with the special conditions of regarding the mass concentration unit, 'mg·L-1', of B as 'ppm' and thinking the provisions of disusing 'ppm' were issued only by China.
