| Abstract: | This paper suggests a possibility that odd points exist on a tube-shaped helical surface outline.And they are analysed by means of differential geometry.Thus, a conclusion is reached quantitatively. |

| Keywords: | differential geometry tube-shaped helical surface odd points curvature radius |
