正交映射与绕点的旋转

Orthogonal Mapping and Rotation about a Point O

本文首先阐迷正交映射的一些基本性质,其次证明一个重要的定理。 定理 空间绕点O的旋转都是绕过O的一条直线的旋转。

This paper at first describes some fundamental properties of the orthegonal mappings. Then we prove an important theorem as follows. Theorem,The rotation about a point O in space is a rotation about a line which through the point O.
