【摘要】 在研究电脉冲结合化疗药物治疗肿瘤时，通常采用脉冲通过电极在肿瘤组织中激发电场，该电场在一定的条件下能使细胞电穿孔，从而促进药物进入肿瘤细胞内。确定电场在肿瘤组织中的分布对肿瘤电化学疗法十分重要。本文对实验中常采用的指数脉冲，通过改变电极结构和不同的脉冲加载方式，对阵列电极激励的电场在肿瘤中的分布进行了计算，得到了电场在组织中的分布情况，结果对利用电脉冲辅助治疗肿瘤的深入研究具有重要的参考价值。

    【Abstract】 While studying the electric pulse supplementary the chemotherapy medication tumor，the pulse is usu-ally adopted to excite the electric field in the tumor through the electrode，the electric field can make the cell electro-porated in certain condition，thus it would promote medicines to enter tumor cell.To confirm electric field distribute electric chemotherapy is very much important to treatment tumor.This paper by changing for the index pulse in re-search that adopts frequently electrode distribution structure and difference add source way ......
