摘　　要：对量子电动力学中的传播过程和发散困难(紫外)等有关内容进行了讨论,对存在的问题给出一种解决的办法,以排除量子电动力学理论因这些问题而面临的尴尬和无奈.同时给出例子证明:对于有意义的量子过程可更简洁地处理并得出同样令人满意的结果.In this paper, we discussed some open questions on the ＇ propagation process＇ and ＇ divergence difficulty （ultraviolet）＇ in Quantum Electrodynimics. Then we gave a way to solve these problems and also gave some apllication exaples they are interesting quantum processes for us. By our method, the theoretical results can be more simply obtained and same satisfaction.
