论文摘要
我们研究了静态曲率的空间形式的第二基本形式的行为，使外部曲率为阴性。如果浸入式束扁平束，我们证明其第二种基本形式将成倍增长。
We investigate the behavior of the second fundamental form of an isometric immersion of a space form with negative curvature into a space form so that the extrinsic curvature is negative. If the immersion has flat normal bundle, we prove that its second fundamental form grows exponentially.
