中国特色社会主义事业发展布局的创新与发展

十八大首次将经济、政治、文化、社会和生态五大建设并列,强调“五位一体”建设中国特色社会主义。由此,中国特色社会主义发展布局历经四个阶段,即：“一个中心,两个基本点”的战略布局,“三位一体”发展布局,“四位一体”发展布局,“五位一体”发展布局。“五位一体”总体布局是一个相互联系、相互协调、相互促进、相辅相成的有机整体,对于开创中国特色社会主义事业新局面意义重大,为到本世纪中叶基本实现社会主义现代化,提供了有力支撑。     

军事指挥类期刊对军事学术研究的透视

军事指挥类期刊主要依靠各级军事指挥员,服务于部队全面建设。在军事学术研究队伍不断发展壮大的今天,军事指挥类期刊为部队“能打仗、打胜仗”军事理论研究服务,但军事学术研究存在着研究群体优势和合成作战理论优势发挥不够的问题。因而,要高度重视军事学术研究人才培养,加大经费投入,强化军兵种之间合成作战理论研究的力度。     

基于变结构方法的空空导弹鲁棒逆控制律设计

为克服动态逆控制严重依赖被控对象精确数学模型且鲁棒性较差的缺点,将动态逆与变结构方法相结合采用双环结构设计了空空导弹鲁棒动态逆控制律.将导弹飞行状态划分成快慢2个回路,慢回路(外环)采用变结构控制,并设计扩张状态观测器,对外环中的不确定性进行估计;快回路(内环)采用动态逆控制.仿真结果表明,所设计的控制律具有较好的动态特性和鲁棒性能.

中制导虚拟目标的定位参数研究

基于虚拟目标的优化导引中制导拦截弹道轨迹及其能耗与虚拟目标的位置紧密相关,决定该位置的参数包括中末制导交班距离和视场基准角等.首先研究了弹道特性随定位参数的变化规律并提出通过滚转实现视场基准角的负取值,在此基础上得出满足多约束条件的虚拟目标定位参数的设置方法.利用该方法所产生的虚拟目标与相应的优化导引律结合,可以很好地满足中制导的要求.

Analysis on damage characteristics and detonation performance of solid rocket engine charge subjected to jet

To further explore the damage characteristics and impact response of the shaped charge to the solid rocket engine (SRE) in storage or transportation, protective armor was designed and the shelled charges model (SCM)/SRE with protective armor impacting by shaped charge tests were conducted. Air overpressures at 5 locations and axial acceleration caused by the explosion were measured, and the experimental results were compared with two air overpressure curves of propellant detonation obtained by related scholars. Afterwards, the finite element software AUTODYN was used to simulate the SCM impacted process and SRE detonation results. The penetration process and the formation cause of damage were analyzed. The detonation performance of TNT, reference propellant, and the propellant used in this experiment was compared. The axial acceleration caused by the explosion was also analyzed. By comprehensive comparison, the energy released by the detonation of this propellant is larger, and the HMX or Al particles contained in this propellant are more than the reference propellant, with a TNT equivalent of 1.168–1.196. Finally, advanced protection armor suggestions were proposed based on the theory of woven fabric rubber composite armor (WFRCA).     

On the Road to the 2015 NPT Review Conference

The second session of the Preparatory Committee for the 2015 Review Conference (RevCon) of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) highlighted two issues in particular—progress toward a Middle East Weapons of Mass Destruction–Free Zone and the Joint Statement on the humanitarian impact of nuclear weapons—that may not only greatly affect the health and vitality of the NPT and the 2015 RevCon, but possibly also have implications for the international nonproliferation regime as a whole. Dr. William Potter, director of the James Martin Center for Nonproliferation Studies, interviewed Ambassador Cornel Feruta, chairman of the 2013 PrepCom, to discuss these and other issues related to the meeting and the future of the treaty and its review process.
