贯彻“三个代表”要求,核心是保持党的先进性。加强党员队伍建设,保持党员的先进性是保持党的先进性的基础。因此,贯彻“三个代表”要求,保持党的先进性,就是要建设一支模范作用好的党员队伍。准确把握“先进性”的深刻内涵“先进”者,先行、先导、先锋也,即走在前列的意思。无论作为党的整体,还是作为党的成员,都应当走在前列。相对群体而言,走在工人阶级前列,走在中华民族的前列;相对于历史而言,走在时代潮流的前列,走在社会发展的前列。理论走在前列,觉悟走在前列,行动走在前列。长期以来,正是因为广大共产党员总是冲锋在前,吃苦在前,为… 相似文献

正"这些战士我们永记不忘,为给子孙留下一个繁华自由的城邦,他们宁愿战死在前方。"这是被镌刻在英雄纪念碑上的古希腊诗人西摩尼得斯的诗句。只要是国家需要,他们一定会选择挺身而出,不计个人得失,无私奉献一切;只要是救人于危难,他们一定会选择舍弃自我,把方便让给别人,把困难留给自己。这便是英雄。从感动中国人物邱少云、罗盛教、欧阳海,到战斗英雄庞国兴、顾金海……英雄始终与一支部队的历史相伴,他们舍身成仁、勇猛无畏、自我牺牲的英勇行为像一道道闪电不断地穿云破雾,成为一支部队的精神灯塔,照亮战士前进的行程。而新一代官兵也正用青春的热血为连队的荣誉注入奋进的风采,续写新的辉煌。 相似文献

临近空间高超声速滑翔飞行器的弹道特性主要受滑翔段初始状态和飞行器控制律影响。在飞行器控制律确定的情况下,研究了滑翔段初始状态对高超声速滑翔飞行器弹道特性的影响规律。按照滑翔弹道的不同形式,在纵向平衡滑翔条件下,通过理论推导得出飞行器状态变量的解析式,结合平衡滑翔条件分析平衡滑翔弹道滑翔段初始状态的唯一性;在纵向跳跃滑翔条件下,构建弹道性能评价指标,利用群智能算法,寻找弹道性能最优时的滑翔段初始状态。利用单因素敏感性分析方法,分别对两种滑翔弹道的滑翔段初始状态进行敏感性分析,初始状态中初始速度对弹道特性的影响最大。对高超声速滑翔飞行器初始状态唯一性与最优性的分析,可为高超声速滑翔飞行器的弹道设计、弹道跟踪、轨迹预测和轨迹优化提供借鉴。 相似文献

分析了聚能射流的形成过程,并对其中的各阶段进行了详细建模。在模型中考虑了炸药爆轰、金属的驱动、药型罩压垮以及射流和杵体的形成过程。采用该模型对某一聚能装药结构进行了计算,计算结果表明:药型罩顶部和底部微元的压垮速度较小,在射流头部形成反向速度梯度,与试验数据吻合较好。该模型对于多级侵彻战斗部的工程设计与侵彻参数的计算具有一定的参考价值。 相似文献

含孔洞铜板复合材料修复疲劳寿命数值分析 总被引:1,自引:1,他引:0
用ANSYS有限元软件对复合材料修复含中心圆孔钢板的疲劳寿命进行了数值分析。研究了孔洞大小、补片长度、宽度和厚度对钢板疲劳寿命的影响;分析了复合材料胶接修补的效果,并对修复所用的复合材料补片的大小及厚度进行了优化设计。研究结果表明,利用复合材料胶接修补带中心圆孔的钢板可以使其疲劳性能提高1.6~18倍。修补时,增加补片宽度和厚度都可增加结构疲劳寿命;补片宽度为孔径8倍以上时,增加宽度对疲劳寿命影响不大;补片的长度为孔径的3~4倍时,修复效果最佳。 相似文献

行政主体理论自行政法成为公法重要组成部分时便成为行政法几个核心理论之一。自《中华人民共和国行政诉讼法》实施以来,行政主体理论研究成为我国行政法理论研究的重点之一。我国关于行政主体的内涵及外延,学术界各抒己见,至今缺乏统一的论断。境外一些行政法理论发达国家和地区的行政主体制度对于我们具有借鉴意义。 相似文献

This article examines the implications of the proliferation of cyberwarfare capabilities for the character and frequency of war. Consideration of strategic logic, perceptions, and bargaining dynamics finds that the size of the effect of the proliferation of cyberwarfare capabilities on the frequency of war will probably be relatively small. This effect will not be constant across all situations; in some cases the advent of cyberwarfare capabilities may decrease the likelihood of war. On the other hand, the use of computer network attack as a brute force weapon will probably become increasingly frequent. 相似文献

Recently, in July 2012, the high-profile and bitterly fought nine-month race for the post of Chair of the African Union (AU) Commission, between Dr Jean Ping of Gabon, and his main challenger, Dr Nkosazana Dlamini-Zuma, culminated in the latter's victory. Her victory came after the deadlock at the Eighteenth AU Summit in January 2012. Borne out of the considered need for a quick fix through reliance on a vote of expediency, the election of Dr Dlamini-Zuma represented a political resolution to the crisis that arose due to the earlier ongoing electoral deadlock. Far from being a competitive election by design, the 2012 AU Commission election by default became transformed into an intensely fought campaign that put the AU in the limelight. This article briefly introduces the electoral process, explains in detail the voting behaviour of AU member states, and offers five specific reasons for the victory of Dr Dlamini-Zuma. On the surface the election looks very competitive, but the article explains why this is not the case. To create greater competition for these posts, the AU needs to overhaul the nomination process and the voting procedure. In this regard, the article proffers detailed analysis and proposes a radical revision of the existing criteria for the nomination. The article also proposes specific recommendations for the amendment of the rules of procedure of the AU Assembly to allow for a qualified majority as a deadlock breaker in the fifth round. It also assesses whether the integrity of the AU Commission election was damaged during the campaigning and voting process. In this regard, it recommends the development of a code of conduct for future elections at the AU. 相似文献

The Royal Armouries of Leeds preserves a rare example of an early fifteenth-century German tournament high saddle that is also one of the earliest complete western medieval saddles preserved. It bears witness to an extreme form of tournament which stood very far from the real practice of war: the Hohenzeuggestech. Impact marks of lances and swords, visible on the saddle, reveal the violence of the blows exchanged during these meetings, a violence often hard to observe in the contemporary but conventional representations of jousters and tourneyers. Thus, by the means of its excellent state of preservation, the Leeds high saddle sheds some light on the jousts and tourneys on high saddles, once so popular and plentiful in what remains of the civilian iconography of the late fourteenth- and the fifteenth-century Germanic world. 相似文献
