一般球对称引力场中的拉普拉斯算子

The Laplace Operator in General Spherically Symmetric Gravitational Fields

从三维平直空间中的梯度算子出发,推导出四维弯曲空时中的梯度算子,进而推导出四维弯曲空时中的Laplace算子;作为特例,得到了一般球对称引力场中的Laplace算子.

Starting from the grade operator in 3 - D fiat space - time is obtained. Further, the Laplace operator is calculated out the Laplace operator in general spherically symmetric gravitational - time, the grade operator in 4 - D curved space in this space - time. For a example, we give out fields.
