基于堆垛机S型曲线运动模型的matlab仿真分析

利用matlab仿真软件对堆垛机的三种S型曲线模型进行分析。在仿真的过程中，引进了跃度的概念，利用做功的基本公式推导出电机的输出瞬时功率。最后通过比较三种控制方法，认为变跃度的方式不仅可以解决曲线平滑的问题，还可以降低选型电机的功率大小。     

模块式小型反应堆研发现状及前景分析

目前的核电站大多数为装机容量较大的反应堆,有些甚至达到了175万千瓦的单机容量,大型堆核电站一次性投入成本高、建造周期长,且难以适应小型电网的需求,而小型反应堆恰好可以解决这一问题,全球掀起了模块式小型核电机组的开发热潮。文章主要介绍了模块式小型反应堆的研发现状、用途,并分析了小型堆与常规堆的优劣势及其发展前景。

地方人大重大事项决定权工作机制探索

党的十八大对坚持和完善人民代表大会制度提出了新的更高要求,十八届三中全会作出的《中共中央关于全面深化改革若干重大问题的决定》,特别明确了人大重大事项决定权。鉴于目前地方人大及其常委会的决定权基本虚置的状况,本文探讨了地方人大重大事项决定权的涵义及工作机制,以期健全人大讨论、决定重大事项制度,推进人民代表大会制度理论和实践创新。

A new assessment of economic integration in East Asia: Application of an industry-specific G-PPP model

It is well known that intra-industry trade and cross-border production networks have promoted economic growth and regional integration in East Asia. However, regional supply and production chains may have been formed differently across industries, reflecting different degrees and a different scope of regional economic linkages at an industry level. This paper makes a threefold contribution. First, to assess industry-level differences, this study adopts the generalized purchasing power parity (G-PPP) model using industry-specific producer prices. Second, the momentum threshold autoregressive (M-TAR) model is employed to allow for possible nonlinearity arising from the dynamic nature of regional economic growth and development. Third, the Granger causality test is also conducted to assess whether regional economies have autonomously integrated. The empirical results reveal that economic integration has progressed more autonomously in the electrical industry, as well as in the transportation equipment industry, as China and the ASEAN countries have become the final destination markets for finished products in these two industries.     

72205综采工作面3300V高压供电技术改造

随着工作面功率的加大,矿井电压过低造成设备启动困难或不启动现象,甚至造成欠电压跳闸,因此1140V电压等级升高到3300V将是煤矿发展的前进方向。     

电力生产、跨省交易与能源环境效率

将电力生产作为先行于其他社会生产的生产环节,在考虑规模越来越大的电力跨省交易和非期望产出(二氧化碳排放、工业废气总排放量、工业废水总排放量等)的基础上,使用非参数网络数据包络分析模型测算了2000—2012年中国省域能源环境效率。结果表明:与考虑电力生产和跨省交易的网络DEA模型相比,利用传统DEA方法会高估电力输入省的能源环境效率、低估电力输出省的能源环境效率。指出调整电力生产布局和跨省输送网络可以有效提高地区的能源环境效率。     

Modelling substitution between domestic and outbound tourism in Australia: A system-of-equations approach

This study uses a system-of-equations approach to model the substitution relationship between Australian domestic and outbound tourism demand. A new price variable based on relative ratios of purchasing power parity index is developed for the substitution analysis. Short-run demand elasticities are calculated based on the estimated error correction almost ideal demand systems. The empirical results reveal significant substitution relationships between Australian domestic tourism and outbound travel to Asia, the UK and the US. This study provides scientific support for necessary policy considerations to promote domestic tourism further.     

从“官控”到“民动”——论政府推进城镇化进程中的公众参与

当下中国的城镇化是＂政府主导＂的城镇化,鲜有程序规制及公众参与,存在着权力裸奔的危险,城镇化推进成果难以获得正当性证成。因此,必须要完善程序机制,扩大公众参与,实现从＂官控＂到＂民动＂的推进模式转变。
