一般稳态空时中的拉普拉斯算子

Laplace Operator in Generally Steady State Space-Time

从欧氏空间梯度与散度的基本概念出发,导出四维弯曲空时中的梯度与散度,得到一般稳态空时中的标量、逆变矢量与协变矢量的Laplace算子.

Starting from the basic conceptions of gradient and divergence in Euclidean space,we drive out the gradient and divergence in 4-D curve space-time,and the Laplace operator of a scalar,or converter and covariant vector in generally steady state space-time are obtained.
