摘要
为比较扬子鳄受精卵及未受精卵卵壳，用扫描电镜观察其超微结构。结果表明：其卵壳由外致密层、蜂窝层、乳突层、外壳膜和内壳膜５层组成。并就经孵化的卵壳外致密层表面出现的腐蚀坑和裂纹产生的原因及生理意义进行了讨论。
The ultrastructure of the eggshell of fertilized egg and unfertilized egg of Alligator sinensis was studied by scanning electron microscopy. The eggshell consists, from the surface inward, of an outer densely calcified zone, a honeycomb zone, a mammillary zone, external eggshell membrane and internal eggshell membrane. The formation and physiological function of the erosion craters and the crackles of the eggshell′s outer densely calcified zone during incubation were also discussed.
