The variable temperature(room temperature to 98 ℃)-variable moisture circulation was used on every component in JH9005 and JBO9013 and binary systems of these components with CG47-2^# binder.The compatibility of the binary system is studied by VST,TG,DTA and microcalorimetry,IR and GC-MS spectrum were used to analyse the parts of condensed phase and gas phase after interaction. The results show that under the conditions of variable temperature -variable moisture circulation, the imcompatibility between JBO9013 and CG47-2^#binder mainly results from the imcompatibility of HMX with CG47-2^# binder and that between JH9005 and CG47-2^# binder mainly results from the imcompatibility of PVB with CG47-2^# binder.
