| 摘 要： | 本文介绍了作者利用电子显微镜对三层式Ｔｉｎ类Ｐｒｏｆｕｓｕｌｉｎｅｌｌａ旋壁超微构造的研究，阐述了Ｐｒｏｆｕｓｕｌｉｎｅｌｌａ三层式旋壁超微结构的特征。电子显微镜研究表明，Ｐｒｏｆｕｓｕｌｉｎｅｌｌａ旋壁中致密层属于原生构造，而内、外疏松层及旋脊具有次生性质。

| Abstract: | An SEM study has been conducted to examine the ultrastructure in the spirotheca of Pro- fusulinella and to reveal the ultra- features of the basic layers comprising the spirotheca of Pro- fusulinella.The study has demonstrated thatthe spirotheca of Profusulinella,the tectum is the primary structure and the outer and inner tectorium and chomata could be considered as a sec- ondary structure |
