评述了１９８５年以来国外低易损性和钝感技术的研究进展；分析对比了低易损性实验技术和小规模实验室试验方法；讨论了最近使用危险性评估协议的活动。此外，还介绍了低易损性固体发动机的设计技术，并对我国发展战术导弹固体发动机低易损性研究和设计的问题提出了建议。

The low vulnerability of solid rocket engine is an important performance in relations to munitions survivability Development of low vulnerabilty and insensitive munitions since 1985 is described,which includes analysis and comparison of methods of subscale laboratory tests The hazard assessment protocols,hot fragment ignition threat/response and low vulnerability design are discussed Finally,policy and way of further research and deveopment of low vulnerability solid rocket engine are proposed
