coulomb gauge meaning in Chinese

库仑规范

The paper proves that in the 2d non - linear case , the coulomb gauge is been meet naturally . in the paper , the second - order isoparametric fem is adopted in the non - linear transient magnetic field simulating excited by current source and the results of transient field and static field solved by the second - order isoparametric and linear fem are compared and analyzed , besides , the effect of the eddy currents in the magnetic materials of the different conductivity is analyzed , it is obtained that the magnetic material of high magnetic conductivity and low loss should be chosen in designing of pma
文中采用二次等参元有限元法推导出在电流源激磁下的非线性瞬态磁场的计算方法和编制了相应的计算程序，并采用二次等参元有限元法和双线性有限元法分别对瞬态场和静态场进行了计算，并对计算结果进行了误差分析，此外，还对不同电导率的导磁材料中涡流产生的影响进行了分析，得到结论设计永磁操动机构时，应选择导磁性能好，损耗低的导磁材料。
