摘　　要：建立了用热重法测定石油磺酸钙中有效组分含量的方法,该方法和SH/T 0034-90《添加剂中有效组分测定法》(橡胶薄膜渗透法)结果基本一致,相关系数达到0.9787.精密度试验表明,本方法具有较好的重复性.A thermogravimetric method for testing the effective fraction of petroleum calcium sulfonate was established. The method is consistent with ＂effective fraction determination in the additive＂ of SH/T0034- 90 （rubber membrane infiltration method）. Its correlation coefficient is 0. 9787. Precision testing indicates that this method has better repeatability.
