The method and assessment standard of munition in slow cook-off test is introduced and the factors affecting slow cook-off response of munition are analyzed.

介绍了弹药慢速烤燃试验方法和评判标准，初步分析了影响弹药慢速烤燃响应的因素。

A porous state generated in the decomposition of ammonium perchlorate(AP) at low temperature is the main reason causing HTPB propellant reacting violently in the slow cook-off test.

结果表明：高氯酸铵（AP）温热分解过程形成的多孔性形貌是导致HTPB推进剂慢速烤燃响应剧烈的主要因素；
