摘要
通过分析坐标系转轴换算原理和导线测量坐标计算原理,导出同一坐标系下全曲线各点和法线平行线与切线平行线交点的坐标计算公式。并利用Casiofx-4500p和Casiofx-4800p计算器进行编程,加快了计算速度,并提高了计算精度。
Trough the analyseing the principle of coordinate system conversion and the principle of conductor measure conclusion, leading the calculation formula of the whole curve's point and the crossing point of tangent parallel lines with vertical parallel lines under the same coordinate system. moreover, utilizing casiofx-4500p and casiofx-4800p calculator to edit the program, compute the speed quickly, and increases to compute the accuracy.
