国内外药典相对密度测定法比较研究

通过对比中国兽药典、中国药典、美国药典和欧洲药典中相对密度测定法，了解四部药典的异同点，旨为中国兽药典引入新方法提供参考。分别对四部药典的收载情况、测定法原理、应用范围等进行比较和讨论。四部药典收载的测定法略有差异，中国兽药典收载的测定法在测定黏稠液体时具有一定局限性。建议中国兽药典在充分调研基础上，引入振荡型密度计测定法。

Analysis on the test of relative density methods among CVP, CP, USP and EP

By comparing the test of relative density methods among Chinese Veterinary Pharmacopoeia(CVP), Chinese Pharmacopoeia(CP), U. S. Pharmacopoeia(USP) and European Pharmacopoeia(EP), understand the similarities and differences between CP and other pharmacopoeia. Compare and discusses the collection situation, the principles of determination and the scope of application, et al. There are little varieties in different pharmacopoeias, and the determination which was collected in CVP have limitations in testing the viscous liquids. It is suggested that U-tube oscillating densitometer in measuring density should be introduced into Chinese Veterinary Pharmacopoeia on the basis of sufficient investigation.
