| Abstract: | The correlation between the tangent perpendicularity coordinate and the calculating deflective angle of a spiral point was analyzed in this paper.When the calculating deflective angle of a spiral point exceeds 90°,the integral formulae of the coordinate should be used.The formulae of the curve’s element of intersection point with any local spiral were derived. |

| Keywords: | local spiral tangent perpendicularity coordinate calculating deflective angle trigonal series calculator integral |
