| 摘 要： | 利用弯曲时空的Maxwell方程，计算了荷电球对称质量外部区域的电磁场能量动量张量，得出了球外空间的电磁场总能量．以致密星(compact star)为例，计算了其外部区域的电磁场总能量，并给出了电磁场能量密度分布曲线，与平直时空的相关结论进行了对比．

| Abstract: | Electromagnetic (EM) energy momentum tensor and total EM energy in external region of charged spherical symmetric mass is calculated based on Maxwell's equation in curved space-time. By numerical calculation for a compact star, total EM energy and distribution curve in external region are discussed. The results in curved space-time are compared with them in flat space-time. |
