摄动项 meaning in Chinese

perturbing term

2 ) based on the maxwell equations of nonlinear media , high - order coupled equations governing the evolution of two orthogonal polarization components of the same wave are derived by using multi - dimension derivation expansion method of singular perturbation theory , and the suitable application range is presented
2 )利用奇异摄动多重尺度导数展开法，从非线性介质中的maxwell方程组出发，导出了包含高阶摄动项的同一光波不同偏振分量的耦合高阶非线性薛定谔方程，并给出了其适用范围。
