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 。By using HU Ning's expressions of energy_momentum pseudo_tensor (EMPT), we obtained the concrete forms of EMPT of cylindrical gravitational waves of single pola_rized states. By analyzing and discussing the positive definite property, asymptotic beha_vior and the total energy of EMPT, we found that HU Ning's expressions of EMPT which are suitable to the Schwarzchild gravitational fields in spherical coordinates can not avoid the difficulty when the total energy of cylindrical gravitational waves is uncertain..
