摘　　要：对3个主流药型的发射药,即单基药、双基药和硝胺药经两种钝感方法处理后的燃烧稳定性进行了分析和评价,总结了不同钝感方法对发射药燃烧稳定性的影响规律。结果表明,两种钝感处理方法使火药燃烧呈现明显的燃速渐增性,但同时也增大了火药燃烧的不稳定性,并使火药的燃速压力指数上升。The combustion stability of three main types of gun propellants (single based propellant, double based propellant and nitramine propellant), which are desensitized with two different methods, is analyzed and evaluated. The effect of the two desensitized methods on combustion stability of the propellants is concluded. It is shown that the burning rate of the propellants increase through both of the two desensitized methods, but the unstability of combustion and the burning ratepressure exponent respectively increase also.
