摘　　要：为了有效地控制尘埃颗粒物的污染,有必要掌握大气尘埃颗粒物的分布,以采取适当的措施.有助于减少灾害的影响.本文是研究一类大气尘埃扩散模型的渐近函数问题.利用变分迭代方法求出轨线.In order to effectively control the pollution of dust particles,it is necessary to master the distribution of atmospheric dust particles so as to take appropriate measures.This is helpful to reduce the impact of disasters.In this paper,we study a class of asymptotic function problems of atmospheric dust diffusion.We use the variational iteration method to find the derailment line.
