5. After the discussion of the numerical simulation method based on the fdtd method and the pml technique , the motions of the charges and the electrical field lines were first employed to describe the radiation procedures of the pulse electromagnetic waves . then the causes of how the charges are accelerated and how the motion status of the charges are maintained were further studied from the angle of interaction of charge and field . after these analyses , it was pointed out that the pulse radiation is due to the suddenly occurred time - varying electrical field ( displacement current ) in the open space . this view was further evidenced by two examples : one is the partly resistance loaded antenna , the other is the partly curved antenna . the radiation procedures of the pulse electromagnetic waves of many different situations were simulated throughout this paper with the contours and waveforms of electric field given . these figures are very helpful to the understanding of the radiation mechanism of the pulse electromagnetic waves
   在討論了基于時域有限差分法和完全匹配層技術的數值模擬方法之后，首先從運動電荷和電力線的角度直觀地描述了脈沖電磁波的輻射過程，然后進一步從場與電荷相互作用的角度分析了天線上電荷是如何被加速以及如何維持其運動狀態(tài)的，指出了開放空間中突然出現的時變電場(位移電流)是脈沖電磁波輻射的根本原因.文中還對局部電阻加載的天線和局部彎曲的天線進行了研究，以進一步說明上述觀點.對多種情況下的脈沖輻射過程進行了數值模擬，并給出了電場的等高線和空間波形圖，這些圖形對理解脈沖電磁波的輻射機理非常有益
