摘　　要：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.发现:R-V的笛卡尔坐标形式是对双极化态的柱面引力波能量动量更为合理的表述.Using the expression of energy-momentum pseudo-tensor of cylindrical gravitational waves of both the polarized states, file authors got the expression of the energy and momentum after a great lot of calculations. The results are discussed, from these discussions, it is concluded that Cartesian coordinates is better than cylindrical coordinates to describe the cylindrical gravitational waves of both the polarized states.
