摘　　要：在一特定谐振腔内,背景静磁场和背景电磁波构成一个引力波的电磁谐振系统。计算了引力波对背景电磁场的一阶和二阶扰动能量。结果表明:一阶扰动能量包含更多关于引力波的信息;二阶扰动能量是正定的。In a particular electromagnetic （EM） resonant cavity, the static magnetic field and the wave of the background EM make up a gravitational waves （GWs） resonance system. The author calculated perturbations energy tensors of the first order and second order on background EM field. The results showed that the first order perturbative energy density contains more informations about GWs and the second order perturbative energy density is always positive.
