摘要: 本文试图从微分几何的角度探讨矢量微分算符▽在各种正交坐标系的梯度、散度、旋度和拉普拉斯符中的不变形式;并探讨了运用△↓算符时容易出现混乱的根源,提出了‘括弧矢量优先’的判断与解决方法.从而扫除了运用△↓算符的若干障碍.

关键词: 矢量微分算符△↓, 矢量分析, 微分几何, 正交曲线坐标系

Abstract: The invariable form of vector-differential operator △↓ in gradient,divergence,rotation and Laplace operator of various orthogonal coordinate systems with differential geometries is studied,and the origin of confusions appeared in the operator △↓ used is also discussed.The opinion and solution of vector operation priority in bracket are advanced,which will remove some misconceptions in the operator △↓.

Key words: vector-differential operator△↓, vector analysis, differential geometry, orthogonal coordinate system
