本文报道了笔者对四十六枚现生和化石四组介形类标本(现生海洋、现生淡水湖泊、化石海相、化石陆相介形类)壳体的内表皮层(即钙质层)进行能谱无机成份定量分析的结果。初步研究表明:介形类钙质壳体中各微量元素的出现频度、平均含量、钙镁比值等有关指数与它们的生活环境有密切关系。 In this paper, we report the inner epidermis (ie, calcareous layer) of the shells of forty-four present and fossil groups of four types of ostracods (present marine, freshwater lakes, fossil marine facies, The results of the quantitative analysis of the inorganic components of the spectrum were performed. Preliminary studies have shown that the occurrence frequency, average content, calcium-magnesium ratio and other related indices of each trace element in the calcareous shell of the astrophy are closely related to their living environment.
