| 摘 要： | 利用胡宁表述求得了单极化态柱面引力波能量动量赝张量的具体形式,通过对其正定性、 渐近行为及总能量的分析和讨论,发现适用于史瓦西球对称引力场的胡宁表述对于柱面引力波尚不能避免由引力场总能量不确定性带来的困难.

| Abstract: | By using HU Ning's expressions ofenergy-momentum pseudo-tensor (EMPT), we obtained the concrete forms of EMPT ofcylindrical gravitational waves of single pola-rized states. By analyzing and discussingthe positive definite property, asymptotic beha-vior and the total energy of EMPT, wefound that HU Ning's expressions of EMPT which are suitable to the Schwarzchildgravitational fields in spherical coordinates can not avoid the difficulty when the totalenergy of cylindrical gravitational waves is uncertain.. |
