electromagnetic field equations meaning in Chinese

麦克斯韦辰程

Since the linear or nonlinear electromagnetic field equations can be written as an infinite - dimensional hamiltonian system , whose solution can be viewed as a hamiltonian flow in the phase space which preserves the symplectic structure in the time direction . such important features should not be neglected during the construction of numerical methods for the field equations
由于线性或非线性的电磁场方程可以转化成无限维的hamilton系统，其结果可以看作是定义在相空间里的时间上保持辛结构的hamilton流，因而在对场方程构造数值算法时就不应忽略这样重要的性质。
