| Abstract: | In this Paper, we expound the deep internal relation between natural coodinates and curvatures, we advance and prove in all the different natural coodinate systems on orbit curves, the judging method of the positive-negative of curvic curvatrres. We open up a path for the degrees of freedom in the forming of coodinate system by using intrinsic equatins to sovie curvilineal restrictal.￣ems. |
