贵刊于 1999年第 2 1卷第 8期第 4 35页曾刊登过王焕江同志的一篇冠名“对清膏相对密度测定方法的改进”的文章 ,我们研读后 ,结合自己的经验分析 ,提出一点不同意见 ,供探讨。在实际操作中 ,若清膏密度较大或者粘稠度较高时 ,用传统的比重瓶法、韦氏比重秤法、简易比重计法测 Your article entitled Comrade Wang Huanjiang’s “Improvement of the Method of Determining the Relative Density of Clear Ointment” was published in your magazine, Vol. 21, No. 8, No. 8, Page 4 of 1999. After we studied it, we combined our experience with it. Give a little different opinion for discussion. In actual operation, if the paste has a high density or a high viscosity, use the traditional pycnometer method, Wechsler scale method, and simple hydrometer method.
