| 摘 要： | 本文认为,大质量活动天体的电磁辐射也携带强烈的时空弯曲信息,为此,先将给出表征时空弯曲信息的Riemann曲率辐射功率表示式;次将它置于二维时空情况做具体计算,表明它内边含有丰富的红移因子;最后为了能同观察比较,再将亮度与恒星星等联系起来。

| Abstract: | An active celestial body has always a rather large mass. Hence the spacetime curvature effect of it is very strong according to the gravitational theory of Einstein. Furthermore, the electromagnetic radiation of it must bring the information of the spacetime curvature clearly. At first, in this paper, an expression for the power of Riemann curvature radiation, which characterizes the spacetime curvature, is given. Then the concrete calculations of the power are made in the case of two-dimension spacetime. It can be seen that the various red-shift factors are included in the result. Finally, in order to compare it with observation, the luminosity ( i. e. power) is linked to the magnitude of the star. |
