摘要
研究了工程上常用的回转体,给出了判别回转体的方法;明确了回转体正截面的交线为一组相互平行的圆;沿主轴方向对称的椭圆型二次曲面体的截交线为两组圆。
This paper studies on usual bodies of rotation in engineering.Presents the method of discriminatory analysis about usual bodies of rotation.Presents the limes of intersection of normal section about usual bodies of rotation,they are only group of parallel circles.When some bodies are symmetric along direction of axis,presents the lines of intersection of section about bodies of elliptic quadratic surface,they are two groups of circles.
