摘　　要：利用“压力对比法”实验技术，通过锰铜压力计测试待测炸药样品和ＬＹ１２铝样品在ＬＹ１２铝飞片的同时撞击下的界面压力ｐｅｘｐ和ｐＡｌ，从冲击波关系式和正交回归直线拟合分析，确定了ＪＢ－９００１钝感炸药的冲击Ｈｕｇｏｎｉｏｔ关系。Shock　Hugoniot　relation　is　the　basic　characteristic　parameters　of　explosive.JB9001　is　a　plastic　bonded　explosive　which　mainly　contains　TATB.JB9001　explosive　and　standard　material　LY12　samples　were　processed　and　their　sizes　are　same.Two　samples　are　symmetrically　put　on　the　LY12　base　plate.One　dimensional　detonation　loading　system　consists　of　detonator,initiation　charge,plane　wave　generator　and　main　charge.The　LY12　flyer　is　driven　by　detonation　wave　which　is　attenuated　with　a　metal　plate.We　use　manganin　gauges　and　oscilloscope　to　record　the　interface　pressure　pexp　and　pAl　between　the　LY12　base　plate　and　the　explosive　sample　as　well　as　between　the　LY12　plate　and　LY12　sample.Since　the　shock　Hugoniot　relation　of　LY12　is　known,we　can　determine　a　reflected　shock　Hugoniot　relation　curve　on　the　Hugoniot　diagram　by　measuring　the　interface　pressure　pAl.On　the　basis　of　the　shock　wave　formula　and　boundary　conditions,the　shock　wave　velocity　us　and　the　particle　velocity　up　behind　the　wave　are　drived.We　have　obtained　the　shock　Hugoniot　relation　of　JB9001　explosive　with　average　density　ρ0=1875g/cm3　by　using　least　square　methodus=(2.78±0.21)+(1.43±0.19)up(0.40km/s≤up≤1.51km/s)experimental　measureing　error　is　less　than　5%.
