1958年黄河汛期工程兵架设浮桥纪事

1958年7月的一个中午,军委工程兵司令员陈士榘上将接到周恩来总理的电话,说毛主席要他马上过去.陈士榘是秋收起义跟随毛泽东上井冈山的,几十年南征北战,他心中最崇敬的就是毛泽东.毛泽东叫他马上过去,而且是总理亲自打电话,陈士榘心想肯定有急事,立即驱车直奔中南海.     

军校思想政治教育的和谐发展观

军校思想政治教育和谐发展,应当注重抓住以下关节点:尚武精神与尚德风气共同发展;科学教育与人文教育协同并进;师德培养与师才积淀相映成辉;理论学习与生活实践知行统一;理论研究、课堂教学与部队现实循环互动。     

叶剑英军事谋略初探

叶剑英在军事谋略领域给后人留下了极其丰厚和宝贵的精神财富。其精髓,正在于他一贯地坚持“把唯物辩证法正确地运用在军事领域中,作为判断情况、定下决心、指导战争的唯一法宝”。本文以此为切点,探讨了叶剑英军事谋略的主要内容及特色:全面、客观地认识和判断战争;辩证地对待战争局部与全局的关系;依据敌我情况运筹作战行动;善于预见,抓住中心;灵活运用谈判、外交、宣传等手段,化劣势为优势;着眼于特点,着眼于发展。     

冷兵器时代战争对经济发展的影响——以唐、五代时期华北平原为考察中心

安史之乱爆发,使华北陷入战争的泥潭,特别是安史之乱后期,中央和安史叛军主要在华北一带争夺,这里的经济发展受到了严重的破坏,"人烟断绝,千里萧条".有些学者认为安史乱后,华北经济从此便衰落下去,也有些学者不赞成此说.那么,华北平原是否由于安史战乱而一蹶不振呢?     

信息化条件下联合作战战场优势转化

信息化条件下联合作战战场优势转化具有信息依赖性、对抗强烈性、效果综合性等特征.组织战场优势转化,必须遵循信息优势、决策优势、行动优势递进转化的规律,搞好总体设计、综合运用各种转化手段,并加强控制和协调,以提高战场优势转化的效率.     

紧紧把握院校特点主动做好安全保密工作

做好新形势下院校安全保密工作,是当前军队院校建设的一项重要任务.我们必须着眼军队院校的地位作用和职能任务,认真研究军队院校的特点及规律,不断提高工作的针对性和实效性,确保院校安全和稳定.     

Experimental and numerical investigation of zirconium jet performance with different liner shapes design

This paper studies the shaped charge jet performance in terms of different liner shapes including conical,bell,hemispherical and bi-conical liners.The critical angles and the relevant flow velocities for the zir-conium liner material were calculated analytically and numerically using Autodyn hydro-code.The relationship between the critical collapse angle and the flow velocity was determined for the conditions of jet formation and coherency.Penetration tests according to the standard testing procedures of API-RP34 (Section-Ⅱ) were performed to validate the numerical predictions of the jet performance of the studied liners.It was found that the four shaped charge liners all produced coherent jets with different performances.The penetration depth of the shaped charges with the bell and the bi-conical liner shapes increased by 10.3％ and 22％,respectively,while the crater diameter of shaped charge with hemispherical liner increased by 85％ representing the formation of an explosively-formed-projectile (EFP),when they are compared with the corresponding jet characteristics of a conical liner shaped charge.     

Investigation of the shock compression behaviors of Al/PTFE composites with experimental and a 3D mesoscale-model

The responses of AI/PTFE reactive materials (RMs) under shock compression were investigated by a single-stage gas gun.A 3D mesoscale-model was established based on micro-computed tomography(micro-CT) slice images and confirmed with experimental results.In the high-pressure stage,the com-posites reacted partially,whereas there were no deviations between the partially reacted Hugoniot and the inert simulation results.The simulation reveals that the Teflon matrix melting on the high shock pressure.Melts and decomposition of the PTFE accelerated the diffusion of the atoms.Thus,the reactions of the Al/PrFE composites are more like a combustion rather than a detonation.     

基于RUP的航空兵作战C~4ISR体系结构研究

本文分析了C4ISR系统的建模特点,对当前主流体系结构模型开发方法进行了比较,提出了运用Rational统一过程（RUP）开发DoDAF体系结构视图产品,并分析了其可行性。结合航空兵作战的特点,采用Rational ROSE建模工具开发了的相关视图产品,描述了航空兵作战过程,证明了RUP对体系结构的开发有着良好的支持作用。     

新型教学模式下教学路径探讨——基于本科教育“四个回归”

实现本科教育的“四个回归”,是新时代背景下高等本科教育教学改革应该完成的目标。要围绕学生的主体地位来建构新型教学模式下教学路径中的学生角色。学生刻苦学习是学生主体学习地位的基础,实行一定比例的淘汰制是学生刻苦学习的重要保证,助力实现“回归常识”。在教师主导课程学习的过程中,要以学生究竟能学到什么和事实上学到什么作为衡量教学效果的标准,助力实现“回归本分”。课程全过程评价方式是动态全方面的评价方式,改变了目的性极强的单一期末考试评价机制,打破了期末考试一考定成绩的传统做法,助力实现“回归初心”和“回归梦想”。
