摘　　要：小角散射(SAS)技术是表征高聚物粘结炸药(PBX)多尺度复杂微结构的重要技术手段。对SAS技术在PBX研究中的实验方法、数据分析模型和多种应用进行了综述。论述了适用于PBX的原位变温、拉伸和压缩加载实验方法,归纳了Guinier、界面、多分散粒子、硬球相互作用和分形等常用模型,概述了它们在PBX研究中的适用条件和范围,总结了近二十年来,国内外应用中子和X射线SAS技术在PBX力热损伤、粘结剂微结构、感度以及爆轰碳产物分析等方面的研究进展。最后,总结了SAS技术在PBX研究中的独特优势,建议加强超小角散射实验技术、PBX原位力?热耦合加载设备和数据分析软件的开发,以及PBX内部多相界面和多尺度孔洞的定量研究。Small - angle scattering(SAS)is a useful technique to characterize the complex multi - scale microstructure of polymer bonded explosives(PBX). In this review the experimental methods,data analysis models and selected applications of SAS for PBX research are presented. First,the in - situ temperature,tensile and compressive loading methods suitable for PBX are dis- cussed. Second,the commonly used models such as Guinier,interface,polydisperse particles,hard sphere interaction,and fractal are summarized and their applicability to PBX research are described. Third,research progress on mechanical and ther- mal damage,binder microstructure,sensitivity,and denotation carbon product analysis over the last 20 years using small-angle X-ray and neutron scattering techniques are summarized. Finally,the advantages of SAS for PBX research are summarized. In ad- dition to the quantitative research of internal multi-phase interfaces and multi-scale voids in PBX,the review points to the contin- ued development of ultra -small-angle scattering(USANS)technique,in -situ mechanical-thermal coupling loading of PBX,and data analysis software.
