做功能力是衡量炸药性能的一个重要指标,现场混装炸药的爆轰感度相对较低,其爆炸性能测试需要大药量的试验方法,故现场混装炸药的做功能力目前还没有较好的测试方法。为了研究现场混装炸药的做功能力,利用弹道抛掷试验测试了现场混装乳化炸药、现场混装铵油炸药和现场混装重铵油炸药分别在不同类型起爆药起爆下的做功能力。结果表明:弹道抛掷法试验药量较大,可以满足用起爆药起爆现场混装工业炸药的条件;通过多次测试对比,发现测试结果几乎不受起爆药做功的影响,测试数据精度高,结果可靠,能够满足测试现场混装工业炸药做功能力的技术条件。 相似文献

This paper describes the explosive fabrication of novel, bulk superconducting composites and monolithic prototypes which serve to explore a range of applications including superconducting tapes, two-terminal linear bus structures for solid-state switching applications, and planar arrays for microwave antenna and magnetic shielding. The systems explored include copper and silver matrices encapsulating Yba2Cu3O7 superconducting powder and metal powder mixtures (Cu and Ag), Bi7Pb3Sr10Ca10Cu15O7 in copper, and Y-Ba-Cu-O and Bi-Pb-Sr-Ca-Cu-O in copper/silver/6061 -T6 aluminum alloy composites. The optimization of the powder consolidation and metal-matrix welding as well as shock-pressure induced alterations in residual superconductivity are examined by measuring bulk resistance versus temperature (R-T) and microwave surface resistances, relative susceptibilities, and relative levitation heights (as an indication of magnetic flux exclusion) with peak shock wave pressures which characterize the explosive (shock-wave) processing. 相似文献
