文摘簡介紹
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...
從上世紀90年代以來,台灣當局不斷否定「一個中國」的原則,頑固推行「台獨」路線,在分裂的道路上越走越遠,中國的「和平統一、一國兩制」的政策正受到嚴峻的挑戰,中國政府不得不進行一場反分裂、反「台獨」的正義斗爭,中國人民解放軍也正積極推進反「台獨」軍事斗爭的各項准備,而輿論戰則是這場斗爭中非常重要的一環。反「台獨」輿論戰主要包含兩方面內容:一是和平時期的反「台獨」輿論宣傳;二是未來對台作戰時的戰時輿論宣傳。本篇論文從開展反「台獨」輿論戰的必要性、輿論戰的功能與特點、各類傳播媒介在輿論戰中的作用、輿論戰的建設和輿論戰的策略運用五個方面研究和探討了如何構建、改進我反「台獨」輿論宣傳工作和提高我軍輿論戰能力的問題。文章剖析中外戰爭中各國輿論戰的實踐活動,歸納總結了輿論戰的功能、流程與特點,分析了不同媒介在現代戰爭中的各自優勢,並以此為基點,從理論建設、組織建設、裝備建設和思想建設四個方面對我軍的輿論戰的組織和手段建設提出了自己的觀點和看法,最後,根據傳播學原理,結合台海兩岸歷史與現狀以及我軍的實際情況,重點論述了未來對台宣傳、對外宣傳以及戰時輿論宣傳的策略運用問題,對改進對台宣傳工作,推進我軍輿論戰建設具有很強的現...
The object of present paper is to investigate the propagation of magneto-viscoelas-tic plane wave in initially stressed concting media. Firstly, the fundamental equation of magneto-vicoelastic wave in a concting medium under an initial stress is deced and employed to investigate the case of hydrostatic initial stress. Secondly, propagation of magneto-elastic plane wave in a conctor under initial uniaxial tension is considered. The final results obtained in above case are in agreeme...
本文研究初始應力及磁場作用下導電粘彈體內的波動特性。首先導出有初始應力及磁場作用下導電粘彈體運動的基本方程,然後用它去研究流體靜壓力及單軸初始應力下波動方程的解,從平面簡諧波的頻散方程,分析了初始應力及磁場對波動傳播的影響。粘彈體用Kelvin-Voigt模型,外磁場假定為均勻。所得結果表明,初始應力對波的影響隨應力性質不同而有所差異,它既影響波的相速也影響波的衰減。磁場影響的大小決定於外磁場的強弱。從本文所得公式中,令外磁場為零,可得初始應力對波特性的影響;如令初始應力為零,就得到磁場對波的影響結果;令兩者同時為零,即得粘彈波的經典結果。

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 conctors 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 conctors located in concting$...

It is of profound significance to attach more importance to the ecation 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 ecation on political theory for the teen�agers shows a tendency of being weakened. Therefore, some counter�measures such as innovating the theories, concting media propa...
加強青少年政治理論教育對建設中國特色的社會主義有重要而深遠的意義。當前由於社會主義市場經濟正在建設中,全球化迅速發展及西方"和平演變"戰略的作用,導致青少年的政治理論教育總體上呈現"弱化"態勢,因此,我們必須引起高度重視,應當採取加強理論創新、重視媒體宣傳、加強高校陣地建設等措施。
