文摘简介绍
Since the 1990s the Taiwan authorities began to take bolder steps towards their goal of independence, defying the "One China Policy" adopted by the Chinese government and its people. The Taiwan authorities have pushed the concept of Taiwan independence so hard that the policy of "Peaceful reunification and One country, two systems" is under great challenge, and that the peace of Taiwan Strait is endangered. In response to this, the Chinese government has launched a campaign of anti-recession and is determin...
从上世纪90年代以来,台湾当局不断否定“一个中国”的原则,顽固推行“台独”路线,在分裂的道路上越走越远,中国的“和平统一、一国两制”的政策正受到严峻的挑战,中国政府不得不进行一场反分裂、反“台独”的正义斗争,中国人民解放军也正积极推进反“台独”军事斗争的各项准备,而舆论战则是这场斗争中非常重要的一环.反“台独”舆论战主要包含两方面内容:一是和平时期的反“台独”舆论宣传;二是未来对台作战时的战时舆论宣传.本篇论文从开展反“台独”舆论战的必要性、舆论战的功能与特点、各类传播媒介在舆论战中的作用、舆论战的建设和舆论战的策略运用五个方面研究和探讨了如何构建、改进我反“台独”舆论宣传工作和提高我军舆论战能力的问题.文章剖析中外战争中各国舆论战的实践活动,归纳总结了舆论战的功能、流程与特点,分析了不同媒介在现代战争中的各自优势,并以此为基点,从理论建设、组织建设、装备建设和思想建设四个方面对我军的舆论战的组织和手段建设提出了自己的观点和看法,最后,根据传播学原理,结合台海两岸历史与现状以及我军的实际情况,重点论述了未来对台宣传、对外宣传以及战时舆论宣传的策略运用问题,对改进对台宣传工作,推进我军舆论战建设具有很强的现...
The object of present paper is to investigate the propagation of magneto-viscoelas-tic plane wave in initially stressed conducting media. Firstly, the fundamental equation of magneto-vicoelastic wave in a conducting medium under an initial stress is deduced and employed to investigate the case of hydrostatic initial stress. Secondly, propagation of magneto-elastic plane wave in a conductor under initial uniaxial tension is considered. The final results obtained in above case are in agreeme...
本文研究初始应力及磁场作用下导电粘弹体内的波动特性.首先导出有初始应力及磁场作用下导电粘弹体运动的基本方程,然后用它去研究流体静压力及单轴初始应力下波动方程的解,从平面简谐波的频散方程,分析了初始应力及磁场对波动传播的影响.粘弹体用Kelvin-Voigt模型,外磁场假定为均匀.所得结果表明,初始应力对波的影响随应力性质不同而有所差异,它既影响波的相速也影响波的衰减.磁场影响的大小决定于外磁场的强弱.从本文所得公式中,令外磁场为零,可得初始应力对波特性的影响;如令初始应力为零,就得到磁场对波的影响结果;令两者同时为零,即得粘弹波的经典结果.

An numerical calculation method of substation grounding grids with unequal potential model is presented in this paper, i.e., the potential drop caused by the interior resistance of conductors is taken into account. A system of equations with the potential at discretization points as unknowns is formed by a field circuit coupling theory. The system is derived based on the nodal potential analysis in the circuit theory and the definition of the mutual resistance between conductors located in conducting$...

It is of profound significance to attach more importance to the education on political theory for the teen?agers in constructing socialism with Chinese characteristics. At present, because of the socialist market economy being under the construction, the globalization and the influence of "peace evolution" from the west, the education on political theory for the teen?agers shows a tendency of being weakened. Therefore, some counter?measures such as innovating the theories, conducting media propa...
加强青少年政治理论教育对建设中国特色的社会主义有重要而深远的意义.当前由于社会主义市场经济正在建设中,全球化迅速发展及西方"和平演变"战略的作用,导致青少年的政治理论教育总体上呈现"弱化"态势,因此,我们必须引起高度重视,应当采取加强理论创新、重视媒体宣传、加强高校阵地建设等措施.
