摘　　要：在量子场论中,利用微扰论处理诸如衰变、散射等粒子反应的问题时,‘传播过程’是其中的一个重要环节.对此环节进行了细致的考察,发现了一个疑点,经过分析,看到了量子场涨落现象的存在以及它们对描述粒子反应过程的重要意义.In quantum field theory,by using the perturbation theory to deal with the problem of particle reaction such as decay and scattering,the ＇propagation process＇ is one of the most important part. A detailed investigation of this part has been carried out,and a doubtful point has been found.Through the analysis,the existence of the phenomenon of quantum field fluctuations and their importance to describe the process of particle reaction has been seen.
