用等离子发射光谱法对其5种石决明样品分别测定了无机微量元素, 并用X衍射仪进行了结构的测定分析.结果表明均含两类成分, 即三方晶系CaCO3(方解石)及斜方晶系CaCO3(文石).同时还进行了红外光谱测定及差热分析.结果表明5种石决明样品图谱特征亦相似.

Inorganic trace element in 5 samples of Abalone She ll were determined by ICP and their structures analyzed by X-ray diffractometer. Result of the study showed that all samples were compose d of two different crystalline structures: the trigonal CaCO3 crystals (calcit e) and rhomboidal CaCO3 crystals (aragonite). Results of IR spectra and diffe r ential thermal analysis of the 5 samples also showed similar atlas characteristi cs..
