摘　　要：在分析了A.I.Morozov一维准中性流体模型特性基础上,给出了影响推力器低频振荡的几种不同电离率及磁场分布等参数,并基于Matlab中的GUIDE模块,将其数学模型中繁琐复杂及抽象的参数设置等键盘操作,设计为图形用户可视化界面(GUI),简洁、直观、清晰地将各影响因素及模型中相关量的变化显示出来,使研究者在研究过程中更加直观与方便.The One-Dimensinal Hydrodynamic Model is researched and servers different parameters of oscil- lation ionization rate and the magentic field distribution which effects law frequency is also given. Moreo- ver,in order to solve the problem of the complex,abstract and tedious of the parameters setting when using the numerical method to solve low frequency oscillation questions, a GUI is designed to help solve the ques- tion which can simplely,intuitively and clearly display changes of the model when some important parame- ters are changed. Also it can make researchers more intuitively and conveniently in the researching process.
