The Energy-momentum Pseudo-tensor of the Cylindrical Gravitational Waves Based on HU Ning's Expressions 基于胡宁表述的柱面引力波能量动量赝张量
Using the expression of energy-momentum pseudo-tensor of cylindrical gravitational waves of both the polarized states, the authors got the expression of the energy and momentum after a great lot of calculations. 利用Rosen-virbhadra(R-V)给出的引力场能量动量赝张量的一般表达式,计算得到了双极化态柱面引力波能量动量的具体形式,并讨论了其正定性问题与渐进行为。
However, the result derived from the second kind of energy-momentum pseudo-tensor cannot guarantee that the radiated power is always positive and it doesnot coincide with Bondi's conclusion. 然而,由满足能量局域条件的第二类能量动量膺张量导出的结果都不能保证辐射功率恒正,且与Bondi的结论不符。
