摘　　要：介绍了碱性镉镍蓄电池用作脉冲大电流恒流源的可行性，叙述了该类电池放电电流的规律和消除记忆效应的办法，并列出了用镉镍蓄电池组装有关恒流源样机的测试数据和实际考验结果。实验证明：在脉冲式大电流场合下，使用蓄电池作能源，可以消除常用的高功率脉冲源对市电电网的冲击，节省大量设备投资，获得具有高稳定度性能的恒流源。This article reports the results of two kinds of cylinder test of the insensitive high explosive JB 9014 which consists mainly of TATB,with diameter of 25mm and 50mm,respectively.By measuring R(t) the expansion history of the TU1 tube driven by detonation products,we have done some comprehensive analysis and 2D numerical simulations for the cylinder tests,to evaluate the ability of doing work and the similarity of cylinder test.By using 2D fluid dynamic numerical simulation,we obtained the parameters of JWL equation of state for JB 9014.The numerical simulation for 2D slipping detonation driven experiment of JB 9014 shows that the parameters of JWL equation of state derived from our experiments and numerical simulations are reliable and with high precision.
