有挠引力场之能动张量密度及自旋密度的再研究

Further study of energy momentum tensor density and spin density of gravitational field with torsion

在有挠情况下对引力场的能动张量密度及自旋密度进行了再研究，肯定了定义Ｔ（Ｇ）μｉｄｅｆδＬＧ／δｈｉμ及Ｃ（Ｇ）μｉｊｄｅｆ－２δＬＧ／δΓｉｊμ的合理性，导出了引力波虽存在但不携带能量、动量及自旋的结论．

The energy momentum tensor density and the spin density of gravitational field with torsion are restudied; the rationalities for definitions T (G) μ i defδL G/δ h i μ and C (G) μ ij def -2 δL G/δ Γ ij μ are confirmed; the conclusions that gravitational wave does not carry energy momentum and spin are deduced.
