谈消防执法如何体现以人为本的理念

以人为本是科学发展观的核心内容,是构建和谐社会的最高价值理念。从消防执法活动的各个环节,进一步阐述以人为本理念在消防执法实践中的体现。     

带落角约束的再入机动弹头的复合导引律

针对再入机动弹头垂直打击目标的要求,研究了具有末端落角约束的复合导引律.该导引律包括俯冲平面内的制导方程和转弯平面内的制导方程,通过在最优导引律的基础上引入滑模变结构控制,增强导引律的鲁棒性.为了减小控制量的抖振和能量损耗,提出了采用RBF(径向基函数)神经网络自适应调节切换项增益的方案,数学仿真验证了该方案的有效性.仿真结果还表明,与最优导引律相比,复合导引律在外界干扰的影响下仍能保持较高的制导精度.

德治与法治的双向互动是推动党风建设的重要手段

以德治国和以法治国是社会主义建设选择的正确方向,在党风建设上亦如此.德法兼治是推动党风建设的重要手段,在运用这一手段过程中应注意道德与法律,实践与知识普及的关系,还应着力建立完善的监督机制和教育体系.     

一种结合弹道规律的模糊交互式多模型算法

针对交互式多模型算法中转移概率矩阵与实际运动不匹配而影响跟踪精度的问题,通过分析某型导弹的典型弹道,将弹道规律融合到模型概率转移矩阵中,然后将转移概率模糊化处理,提出了一种基于弹道规律的模糊交互式多模型算法,然后以导弹蛇形运动转至比例导引的机动过程为例进行了仿真验证,比较了典型交互式多模型算法和模糊交互式多模型算法的跟踪性能。仿真结果表明:该算法可显著提高导弹机动段的跟踪精度。     

Soldiers as victims: behind military barracks in the post-colonial African army

This paper examines the ways in which the military infringes on the social and political rights of soldiers who joined the Zimbabwe National Army in post-independence Zimbabwe. Contrary to the scholarly and policy debates that present Zimbabwean soldiers as the silent prop behind President Robert Mugabe and the perpetrators of political violence, this paper argues that these soldiers have also been victimised in army barracks. The victimhood of soldiers has been explicit in the ways in which they are forced to execute their duties beyond their professional expectations. In substantiating this argument, the paper explores the unethical military training and the ways in which soldiers are disciplined and punished through Chapter 11:02 of the draconian Defence Act. The paper’s contribution stems from a ‘rights’ perspective that emphasises the right to freedom, justice and protection, which is usually quite silent in the military. But the question is how can soldiers’ concerns be translated into new practices without compromising so-called ‘state security’?     

滑模控制的新型双幂次组合函数趋近律

提出一种基于双幂次组合函数趋近律的新型滑模控制方案。与现有的快速幂次或双幂次趋近律相比,具有更快的收敛速度,同时还保持了全局固定时间收敛特性,收敛时间上界与滑模初值无关。当系统存在有界扰动时,能够使滑模变量在有限时间内收敛到稳态误差界内,同时其稳态误差要小于现有方法的。仿真实验验证了该方法的有效性及理论分析的正确性。     

Expanding the Dragon’s Reach:The Rise of China’s Anti-access Naval Doctrine and Forces

Among the multiple dimensions of the tous azimuths modernisation of Chinese naval forces, the development of China’s anti-access capacity has recently elicited considerable interest. The important link between this capacity and an overarching vision of the use of force – i.e. a naval doctrine – has, however, often been left implicit. This article shows that the particular development of China’s naval anti-access forces – more precisely, forces with an impact on the naval balance – can be explained by a shift of China’s naval doctrine towards a distinctly pre-emptive posture, which, itself, stems from the set of constraints imposed by the framework of ‘local war under informationised conditions’.     

Hardening the Hard,Softening the Soft: Assertiveness and China’s Regional Strategy

There is a growing view that the emerging brand of Chinese regional diplomacy in recent years is increasingly assertive. This article attempts to make better sense of this perceived more forceful Chinese diplomacy. It argues that Chinese regional behavior is more profitably understood through the lens of a two-pronged foreign policy strategy that combines two particular aspects. One is a tougher and more uncompromising approach toward issues that China regards as concerning its core interests. The other is a more flexible and cooperative position toward interests that, while significant, are of secondary importance.     

可调喷油规律下柴油机性能随喷油提前角的影响

为获取可调喷油规律条件下,喷油提前角对柴油机性能的影响规律及成因机理。在实现可调喷油规律喷射的基础上,基于Fire软件建立了柴油机工作过程计算模型,并通过试验对模型中的主要参数进行了标定,进而利用模型分析了靴形喷油规律下柴油机性能随喷油提前角的变化。结果表明：随着增压时刻的滞后,喷油规律由矩形过渡到斜坡形再到靴形,实现了灵活可调的喷油规律。在靴形喷油规律条件下,存在一个最佳的喷油提前角,使柴油机的动力性和经济性均达到最优。同时,随着喷油提前角的增大,柴油机缸内压力、缸内温度以及放热率均逐渐升高,且到达各自最大值的时刻前移,而NOx排放量和碳烟排放量则分别呈现出增加和减小的趋势。
