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
由於線性或非線性的電磁場方程可以轉化成無限維的hamilton系統，其結果可以看作是定義在相空間里的時間上保持辛結構的hamilton流，因而在對場方程構造數值演算法時就不應忽略這樣重要的性質。 -
The symplectic integrator method is the new time - domain method which is specialized to a hamiltonian system and can preserve the symple ctic structure of the phase space
辛演算法正是用來保持hamilton系統相空間辛結構的一種新的數值方法，並且在計算精度、時間上具有優越性。 -
At the same time, we try to analysis the relations between the special cases of dirac structure and the poisson structure or symplectic structure, moreover the sufficiency and necessary condition in which the dirac structure is integrable is given
