The angular coordinate used a DVR based on Legendre polynomials and the radial coordinates utilized a DVR based on sine basis functions.

角度部分的DVR基组选择勒让德多项式形式，而径向坐标采用正弦函数形式。

All classic orbital elements and usual angular motion parameters can be calculated with the new set of generalized coordinates and their rates.

经典的质心轨道根数，以及系绳在质心轨道面内与轨道面外的摆动角，均可由上述六个广义坐标及其广义速度确定。
