摘　　要：就影响重复性的关键因素、测试次数、m值和标准程序作了探索,对测试次数与用回归系数m值来评价聚合物抑制性的合理性作了讨论。试验表明,重复性差的另一个原因是搅拌杯漏失。用改进的搅拌杯、国产滤纸,测试5次,结果可以在±3％以内定量重复。用此法已将3个CST试验程序标准化。根据回归系数m值来评价聚合物的抑制能力是一种可行的推荐作法。The main reason causing poor repeatability is the leakage of stirring cup. Tests indicate that the repeatability can be improved effectively (repeat quantitatively in the range of ± 3 %) by using modified stirring cup, Chinese-built filter paper instead of imported one while testing five times. Three standard procedures for CST are given. It is shown that the value of regression coefficient can be used to evaluate the inhibition property of polymer .
