摘要
利用活动标架法研究Ｓａｓａｋｉａｎ空间形式的积分子流形的内蕴刚性，得到了优于Ｂｌａｉｒｓ’的一个Ｐｉｎｃｈｉｎｇ条件，并用不同于Ｍａｅｄａ’ｓ的方法证明了Ｍａｅｄａ的一个Ｐｉｎｃｈｉｎｇ定理．
Intrisic rigidity for integral submanifolds of a sasakian space form is discussed by the moving frames. The pinching condition which is better than Blair's condition is given. Maeda's pinching theorem is proved by the method which is different form Maeda's.
