摘　　要：用体积法测定了B/BaSO4/BaGO4延期药装药密度和压药压力的关系:利用光电转换原理测定了B/BaSO4/BaGO4延期药的延期时间,得出B/BaSO4/BaGO4延期药延迟时间和装药密度的关系,实验证明装药密度是影响延期药延期时间和延期精度的重要参数。得出压药压力在20—240MPa范围改变时,对应的装药密度变化为1.3-2.7g/cm3,在密度装药密度变化为1.3-2.7g/cm3范围内,对应的点火延迟时间变化为4.1-1.8s。在装药密度≤2.50g/cm3时,点火延迟时间随密度变化较快,装药密度≥2.60g·em时,点火延迟时问随密度增加趋于稳定,最短点火延迟时间约为1.80s。在装药密度较低时,如低于2.30g/cm3,对应压药压力低于120MPa,实验数据散布较大。The relationship between charge density and loading pressure was studied by volumetric method, also the relationship between ignition delay time and charge density of B/BaSO4/BaGO4 was studied 。It is validated that the loading intensity of delay composition is the key factor for ignition delay time and time precision by experiments。The density ranges of 1.3-2.7g/cm3 corresponding to the loading pressure ranges of 20—220MPa and the delay time ranges of 4.1-1.8s corresponding to the density ranges of 1.3-2.7g/cm3 were obtained.With the density below 2.60g·em-3,the ignition delay time changes faster with density,and tends to be stable when the density overpasses 2.68g·cm-3 with the shortest delay time in 1.8s。When the density is lower,such as below 2.50 g·cm-3 and the corresponding loading pressure is less than 180 MPa,scattering of experimental data is bigger.
