摘　　要：根据引力场能量动量的Landau-Lifshitz表述,求出了笛卡尔坐标系中的双极化态柱面引力波能量动量密度及角动量的具体形式;结果表明:采用笛卡尔坐标系可以合理地描述双极化态柱面引力波。Acording to Landau -Lifshitz prescription of energy- momentum of gravitation field, the concrete forms of energy - momentum densities and angular momentum of cylindrical gravitational waves of the double polarized states have been obtained in Cartesian coordinates system. The results of calculation show that the cylindrical gravitational waves of the double polarized states can be described reasonably by adopting the Cartesian coordinates.
