Burgers’方程的守恒律

守恒律历来是物理学研究的中心课题之一.在数学中借助运动常数,对偏微分方程的解作出先验估计,这些估计是方程的解存在性、唯一性及稳定性的核心关键.在计算数学中较好的稳定差分格式,也用到守恒律.在Noether's定理求守恒律的基础上,利用Burgers'方程的对称群构造出相关的伴随因子得出了Burgers'方程的一类守恒律.     

关于法律战的若干问题研究

在军事斗争中,我军应准确把握法律战的含义,使军事斗争与法律战有机结合。在信息化战争条件下,法律战正面临着前所未有的挑战。法律战只有与舆论战、心理战相结合,才能发挥出“三战”整体效益。军事优势是法律战获胜的前提和关键。武警部队应结合军事工作的基本特点,努力提高法律战的作战能力。     

中国西部气候特点及其变化浅析

气候特点及其变化规律在生态环境演变中往往占据主导地位,它制约着区域的能量基础、水热组合及自然要素的发育方向,规定了物质、能量循环的规模、强度和结构,最终决定了该地区的生态、环境的类型、质量及承载能力。因此,掌握西部气候及其变化规律,可以为西部生态环境建设和保护提供理论依据和实践指导。

Detecting Problems in Military Expenditure Data Using Digital Analysis

The UN asks governments to report key figures of their annual military budgets with the aim of creating trust among member states. This goal can only be achieved if the data reported is accurate. However, although there are many reasons for governments to falsify data, the UN does not check for manipulation. In this paper, we apply Benford’s law to the military expenditure data of 27 states taken from the UN register. Our analysis of the first digits shows that the states with the greatest deviations from the expected Benford distribution and therefore the lowest data quality are the USA and the UK.     

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’?     

径向载荷作用下管道挤压变形过程数值模拟

野外埋地敷设的长距离输油管道发生断裂等较大事故时,采用管道局部挤压的方式可以在较短时间内将管道快速压扁以截断流油。为设计管道挤压截流装置,运用ANSYS Workbench建立上下压头加载作用下管道挤压的有限元模型,完成对ф159 mm×5 mm的45号钢挤压变形模拟仿真,得到管道挤压的等效应力、位移分布、变形范围和载荷-位移曲线等。将模拟数据与实验数据进行对比,两者结果比较吻合,可以为管道泄漏抢修提供理论和实践参考。     

持续推进强大海军建设必须要有良好的法治环境作基础

海军建设任务重、周期长、投入大的特点决定了持续推进强大海军建设,必须要有良好的法治环境作基础。文章坚持运用辩证唯物主义的立场、观点和方法,通过对近代中日两国海军建设在经费投入、规划审定、法规制定三个方面具体做法的比较,深入分析了近代中日两国海军兴亡背后的法制因素,指出当前持续推进强大海军建设必须深入学习贯彻党的十八届四中全会精神,按照依法治军方略,强力推进依法治军进程。
