| 摘 要： | 本文讨论了:(1)?~2U在柱和球坐标系中的表示式;(2)得到了一个简单的变换公式:dQ_i=?/?1_i[(?u)_i·S_i]dl_i;(3)避开了一般曲线坐标繁杂的变换,从直观几何图象顺手就可写出?~2u在柱和球坐标系中的表示式。

| Abstract: | In this paper, we get the expression off Δ~2U in spherical and cylinde-rical coodinates and a simple formula: dQ_i= ?/?l_i[(?_u) i·s_i]dl_i. Avo-iding the ordinary expression of coodinate transformation, we get the exp-ression of ?~2 U in spherical and cylinderical coodinate system from a si-mple geometry picture. |
