中文摘要：

对黑索今（RDX）干燥过程的影响因素进行了综合分析。通过单因素实验和正交实验，对影响RDX干燥过程的主要因素及其影响显著性进行了研究，得到干燥RDX的最佳干燥条件。干基含水量、真空度、温度对RDX干燥过程有重要影响，影响的显著性顺序为：温度的影响显著性强于真空度，更强于干基含水量。建议RDX的干燥条件是：温度80℃，真空度0．05MPa，干基含水量10％。

英文摘要：

The conditions for the drying of RDX were optimized. Through single factor and orthogonal test, the main factors affecting the drying process and their orders were investigated, and the optimal drying conditions were gained. The results show that the relative moisture content, vacuum, temperature are important factors in the drying process of RDX, with the influence order is temperature 〉 vacuum 〉 relative moisture content, and the optimal drying condition suggested is the temperature 80℃, vacuum 0.05MPa and relative moisture content 10%.
