摘 要 ：采用二氧化碳重量法测定瓦楞子不同火候煅制品碳酸钙的分解率。建立了简易判断贝壳类煅制品碳酸钙是否发生分解的水浸液ｐＨ值测定法。并对６城市贝壳类煅制品外观与内在质量进行了考察和比较。

Abstract:The decomposition rates of CaCO₃ in Concha Arcae calcined at various temperatures were determinedby CO₂ gravimetry,and a simple methed was established to judge the decomposition of CaCO₃ in calcined shell drugs.In addition,the quality of shell drugs obtained commercially from six cities was compared.
