摘　　要：为精确测量炸药拟定态爆速,设计了尖形探针和相应的实验测量方法,测量了有机玻璃、不锈钢、铝合金约束下片状TATB为基钝感炸药的拟定态爆速,结果为(7.527±0.017)km.s-1。表明:采用尖形电探针测量钝感炸药爆速的不确定度为19 m.s-1,相对不确定度为0.25%,与洛斯阿拉莫斯国家实验室(LANL)精密爆轰物理实验结果相当,为精密爆轰物理实验提供了一种新的爆速测量方法。The pin shape probe and corresponding experiment method was designed to measure the precision steady detonation velocity. The steady detonation velocities of sheet insensitive high explosive （IHE） based on TATB at the restricted by polymethylmethacrylate,stainless steel and aluminum alloy were measured by needle shape pins,and the uncertainty of measurement velocity was analyzed. The result shows that the uncertainty of detonation velocity in IHE based TATB measurement using this method is not exceed 19 m·s^-1 ,and the relatively uncertainty is not exceed 0.25%. Results are accordant with the precision detonation physics experiment result of Los Alamos National Laboratory （LANL）. It is a high precision detonation velocity measurement method for precision detonation physics.
