摘　　要：文章采用液中放电等离子体降解TNT废液,影响降解的因素为放电时间、放电电压、电极间距、气流量、初始浓度、初始电导,采用了无因次方法对降解效率与影响因素之间进行了关联,建立了降解过程的数学模型,并对数学模型进行了分析,得出的结论是:模型方程的置信度为0.71,方程回归系数都显著不等于零,所求的模型是实用的,这为下一步的放大改进工作奠定了良好的基础。This paper adopts eletro-hydraulic discharge plasma to degrade TNT wastewater,the influencing factors includes discharge time,peak voltage,electrode distance,airflow,initial solution concentration,initial solution conductance.Mathematical model of degradation was established using dimensional analysis through relating main influence factors.This study indicates that similitude quotiety of the mathematical model is 0.71;regression quotiety is obviously not equal to zero.The mathematical model requested is practical and it provides a good foundation for further work of magnified experiment.
