试论毛泽东新闻宣传工作的群众观

毛泽东新闻宣传工作的群众观是对马克思主义新闻观的创新发展,在中国革命和社会主义建设中发挥了极其重要的作用。新形势下,重温革命导师关于新闻宣传工作的基本观点和指导思想,对加强党的建设、加强党对新闻宣传工作的领导具有重大的现实意义。从人民群众是党的新闻宣传工作的主要对象、教育并武装群众是党的新闻宣传工作的首要任务、党的新闻宣传工作必须与人民群众血脉相通等三个方面,阐述了毛泽东新闻宣传工作的群众观所包含的主要内容。     

“It would be impossible to estimate the value of these works...” Mass Production at Springfield Armory during the American Civil War

The U.S. Armory in Springfield, Massachusetts, rarely appears in Civil War histories except perhaps as an unexplained statistical wonder. By late 1863, the Armory was the largest single supplier of rifles to Union forces. Springfield Armory workers out-produced over thirty American contractors, making more Army rifles at less cost while providing contractors with gauges, inspectors, and models, even though there were significant wartime private-sector mechanical innovations. This article identifies and explains the factors in the Armory’s success, provides context on contemporary American arms production and rifle models, and argues that the Armory’s methods and performance were among the first if not the first example of mass production in American small arms manufacture. The relative brevity of the Civil War episode, and the fact that it was not repeated in any comparable way at the Armory until World War II, has obscured its significance in American manufacturing history.     

模型三组元喷嘴雾化SMD变化规律

为了充分研究新型三组元喷嘴的内混腔雾化特性 ,设计了模型喷嘴进行多工况试验。试验发现 ,维持气体或液体压降不变 ,改变另一种介质的压降 ,会得到不同的雾化平均直径随气体压降或液体压降 ,以及气液比ALR的变化曲线 ,这些曲线有着明显的规律。大量试验表明 ,虽然平均直径SMD随气体压降或液体压降的变化曲线明显不同 ,但其随气液比的变化规律却趋于相同     

物伞系统动力特性研究

研究了降落伞一物体系统的空间运动。假定降落伞和物体都有６个自由度，两者通过吊带连接起来。推导了物伞系统运动的非线性微分方程，运动方程中没有考虑伞绳和吊带的弹性。用所得数学模型分析了减速伞回收系统的动力特性，给出了仿真计算结果。

一类非自治单种群模型的持久性

在这篇文章里，我们利用微分方程比较原理以及一些精细的分析方法，研究了具有无限时滞和反馈控制的非自治单种群模型的持久性，得到了一些新的结论。     

Saddam versus the inspectors: the impact of regime security on the verification of Iraq’s WMD disarmament

The discovery that Iraq had no weapons of mass destruction (WMD) in 2003 raised the question of why Saddam had prevented UN weapons inspectors from fully accounting for his disarmament. The leading explanation for Saddam’s behavior is that he valued ambiguity as part of a strategy of ‘deterrence by doubt’. This article argues that Iraq’s obstruction of inspectors in the late 1990s was motivated by his desire to shield Iraq’s regime security apparatus from UNSCOM’s intrusive counter-concealment inspections. The failure to understand how strongly Saddam’s concerns about his personal safety drove Iraq’s contentious relationship with UNSCOM set the stage for the invasion of Iraq in 2003.     

边境地区群体性事件预警指标体系构建研究

科学、可行的指标体系是群体性事件预警的核心。在坚持完备性与最小性原则、科学性与可行性原则、敏感性与动态性原则、全局性与针对性原则的前提下，利用层次分析法、专家调查法，构建了以边境地区经济、社会保障、公共安全维护、民族与宗教、边民心理状况以及周边环境六大因素为支撑的边境地区群体性事件预警指标内容，并形成了6个一级指标，12个二级指标，44个三级指标的边境地区群体性事件预警指标体系。
