【摘要】 广义协变的能量动量守恒定律和作者建立的广义协变的角动量守恒定律克服了其它各种表述形式的困难，本文利用它们研究了Ｒｏｂｅｒｔｓｏｎ－Ｗａｌｋｅｒ宇宙的能量动量和角动量．由于本文采用的守恒定律是广义协变的，所以与坐标选择无关，这与其它文献不同．结果表明Ｒ－Ｗ宇宙的能量动量和角动量皆为零，并给出了零结果的物理诠释．更多还原

【Abstract】 The generally covariant conservation law of energymomentum and the generally covariant conservation law of angularmomentum established by the author overcome the difficulties of other definitions. The present paper studies the energymomentum and angularmomentum of the RobertsonWalker universe. Being different from other discussions, our discussion is coordinate independent due to the general covariance of the conservation laws. It shows that the energymomentum and angularmomentum of the RW universe are both vanishing. Some discussions and interpretations are also given.更多还原
