The electrochemical properties of eight new divalent transition metal benzenesulphonate complexes with 1,10-phenanthroline in different solvents and supporting electrolytes were investigated by means of cyclic voltammetry(CV). Based on the CV data the influences of various coordination modes on the electrochemical behavior of the complexes were discussed. The diffusion coefficient D c and rate constant k s of those complexes in DMF systems were estimated according to CV and the results show that these processes were all quasi-reversible.

反应性合金是一种高密度超钝感的新型含能材料,在高速撞击下可释放大量化学能,具有与动能耦合毁伤目标的潜力。通过弹道枪驱动非晶合金类、传统合金类和高熵合金类反应性合金样品,以1500 m/s速度撞击准密闭容器和间隔靶。对比分析了3种样品冲击释能行为和对间隔靶耦合毁伤能力的差异。结果显示:反应性合金样品在高速侵彻靶板后形成的燃烧碎片云对间隔靶兼具动能和化学能毁伤能力;化学能释放效率与样品的静态抗压强度正相关;由于样品所携带的化学能和动能随着燃烧碎片云运动,释放在靶后不同空间处,故对间隔靶的毁伤能力与其总携带能量无关;化学能对耦合毁伤能力的贡献程度主要取决于释能效率。

为研究高强度、高密度钨锆铪活性合金破片在冲击加载下的化学能增强动能毁伤能力,开展弹道炮驱动破片对单层Q235钢板和钢板后加3层LY12薄铝板间隔靶的侵彻实验。采用高速摄影机拍摄破片侵彻钢板后的释能行为和对间隔靶的毁伤过程,测得钢板后碎片云区的形状和运动特征参数,得到碎云区对钢板后不同位置处间隔靶的毁伤面积和容积。研究结果表明:钨锆铪合金活性破片在高速侵彻钢板过程中,板前化学能耗极低,板后则形成类椭球状兼有动能和化学能的耦合能量区,该能量区对间隔靶的毁伤模式在激活点近场区以化学能增强动能毁伤为主,在远场区以动能毁伤为主;单枚直径9.5 mm破片对距钢板125 mm和360 mm位置处的间隔靶毁伤容积分别可达292.7 cm^(3)和331.5 cm^(3).
