为了研究钢壳体PELE爆裂效应与影响因素之间的数学关系,对钢壳体PELE侵彻钢板进行了数值仿真和试验。采用均匀设计法设计仿真工况,将仿真结果进行回归分析,得出爆裂效应与影响因素之间的数学关系式,实弹侵彻实验结果与仿真结果基本吻合。研究表明,影响因素均与壳体爆裂长度成非线性关系,增大靶板厚度、弹芯长度和着速或减小壳体厚度均有利于提高钢壳体的爆裂效应。相关结论为PELE的工程设计和应用提供了理论基础。 相似文献

鲁迅以魏晋诗人的人格理想对诗性精神的影响为思考脉络,来考察这一时期的文化风貌之于诗歌的意义,并用“魏晋风度”来概括。在精神文化传承上,鲁迅和魏晋诗人都对酒情有独钟,借助于酒文化获得精神上的超越。在艺术创作上,鲁迅诗歌与魏晋南北朝诗歌都有着沉郁、苍劲的特点,也都呈现出率真自然的风格。 相似文献

ABSTRACTThe conventional wisdom about the 1992 US intervention in Somalia is that it was a quintessentially humanitarian mission pushed by President George H. W. Bush. This article challenges that interpretation, drawing on newly declassified documents. The Somalia intervention, I argue, was largely a pragmatic response to concerns held by the US military. In late 1992, as the small UN mission in Somalia was collapsing, senior American generals worried about being drawn into the resulting vacuum. Hence they reluctantly recommended a robust US intervention, in the expectation that this would allow the UN to assemble a larger peacekeeping force that would take over within months. The intervention ultimately failed, but the military learned useful lessons from this experience on how to achieve smoother UN handoffs in the future and thus effectively shift longer-term stabilisation burdens to the international community. 相似文献
