摘要：

本文利用扫描电子显微镜和Ｘ－能谱仪观测南极阿德雷企鹅的卵壳以了解阿德雷企鹅卵壳的微结构和各壳层的主要成分，结果表明：阿德雷企鹅卵壳的外表面和内表面分别为板块状结构的外皮层和致密的纤维网状结构的内膜层，中间为结构不同、成分组成不同和含量不同的三层结构，其中外层和中层的主要成分为钙，含量分别为９５．８１％、９７．８１％，同时含有少量的磷，含量分别为４．１９％、１．８７％，外层显示与其他鸟类或爬行类卵壳基本相似的碳酸钙方解石片层结构，而内层的主要成分是硫酸钙，呈现与其他鸟类或爬行动物的卵壳较大的差别，硫含量高达８４．２６％。

Abstract:

An analysis is made of the fine structure and element composition of egg shell of adélie pengiun, Pygoscelis adeliae by SEM and EDX. The results show that the outer and inner surfaces of the egg shell are irregular platelet like cortex and compactly reticulated fibriform endomembrane respectively. There are three layer structures, in which the texture and compostion exist distinct differences, between the outer cortex and the endomembrane. Among them,the outer and mid layer are mainly composed of calcium carbonate and a small amount of calcium phosphate, The content of calcium and phosphorus is Ca: 95.81% and 97.81%, P:4.19%and 1.87%, SEM observations reveal that the calcium carbonatecalcite layer structure in the outer layer is similar to that in egg shell of other birds or reptiles. However, the main component of the inner layer in the egg shell of adelie pengiun, which is greatly different from the egg shell of other birds or reptiles, is calcium sulphate, containing up to 84.26% sulphur.
