| 摘 要： | 本文利用电磁场能动张量本征矢量的类时、类空和类光的性质来判断有无电磁辐射,并推广到引力辐射,即利用引力场Weyl张量本征双矢量主方向的性质来判定各类引力场有无引力辐射。

| Abstract: | In this paper,we use the timelike character of the eigenvector of energy-me-mentum tensor to judge whether the electromagnetic field have radiation.This me-thod can be generalized to the gravitational radiation.Analogically,we can deter-mine whether the gravitational field have radiation with the character of theprincipal direction of the eigen bivector that belongs to Weyl tensor. |
