内陆外向型城市建设的障碍因素集层次结构分析模型

本文以西安内陆外向型城市建设为例，运用系统工程的基本思想、网络理论及综合评价技术，构建了内陆外向型城市建设的障碍因素集层次结构分析模型，找到了西安内陆外向型城市建设的主要和次要障碍因素集，提出了在目前和今后较长的一段时间内，西安内陆外向型城市建设的主要任务是大力发展第三产业。本模型方法对其它地区的内陆外向型城市建设及复杂的社会经济系统障碍因素定量分析研究也有较好的参考价值     

A gold key to initiate a new situation in family planning work]

Because of the popularization of a responsible agricultural production system, the livilihood of peasants has been improving greatly, while the demands and needs of the general public are also increasing at the same time. Still under the influence of the traditional belief of carrying on one's family line and emphasis on having male children, married people prefer to have more childre, and the birth rate is now rising again. In order to solve this new problem, we need to teach the peasants national policies on population, land utilization, and food supply. In order to initiate a new situation in family planning work, we need to control this "gold key" of ideological education and propaganda. The emphasis should be placed on ideological education for cadres at all levels as well as the general public in order that they may understand the Party's strategy. Education on the national strategy should be combined with material interests of the peasants, and reward and punishment in production should also be linked up with that of family planning. Social measures are needed to reduce economic burdens of the peasants, offer better treatment for single-child households, and provide adequate care for old and retired people. Family planning projects should be consolidated and improved. Scientific management, facilities and techniques for birth control, compensation for working personnel in family planning, and other practical problems deserve immediate attention and solution.     

Energy conservation through resource-aware movement in heterogeneous mobile ad hoc networks

Energy conservation in mobile ad hoc networks is of paramount importance because most mobile nodes usually have very limited energy supply. Previous research on this issue focused on the design at the network or MAC or physical layer. In this paper, we study this problem from the new perspective of node mobility, i.e., analyzing the impact of node movement on energy conservation. In particular, armed with the inherent resource heterogeneity in mobile ad hoc networks, we propose a novel resource-aware movement strategy to make better use of some powerful nodes to achieve energy conservation. We also formulate the resource-aware movement as a NP-complete distance-constrained least-cost (DCLC) routing problem and propose an efficient heuristic solution. Extensive simulations have been used to demonstrate the effectiveness of the proposed schemes.     

铝钢异种金属CMT焊接变形研究

针对目前使用冷金属过度焊（CMT）对铝钢异种金属薄板进行焊接时,存在焊接质量差,焊接热变形及使用性能低等缺点,对薄板件焊接过程采用SYSWELD软件进行模拟。通过不同的试验参数进行组合,得出金属薄板在X,Y以及整体方向上的焊接变形量,分析不同焊接参数对焊接热变形的影响规律。结果表明：在达到焊接要求的前提下,应尽量减少焊接时间和焊接电流;在一定焊接电压范围内,焊接电压越大,相同时间内焊接变形量就越大,Y方向焊接变形值约为X方向的1.5倍;为了避免焊接变形量过大,宜选用相对较大的焊接速度。

先买权基础理论之探究

先买权可以分为法定先买权与意定先买权、物权性先买权与债法上的先买权。债法上的先买权是一种形成权,不具有对抗第三人的效力;物权性先买权则是一种物权取得权,具有对抗第三人的效力。我国民事立法中规定的先买权应解释为债法上的先买权,不具有对抗第三人的效力。     

一种意识形态的主张——论阿尔都塞的戏剧批评

阿尔都塞作为一位杰出的马克思主义哲学家,在当代西方人文学术领域和左派政治领域占有重要地位。本文试图通过对阿尔都塞的《皮科罗剧团,贝尔多拉西和布莱希特(关于一部唯物主义戏剧的笔记)》的文本解读,通过其具有独创性的意识形态理论分析论述意识形态与文艺的关系,并揭示这一理论对当代文学/文化领域的理论启示意义。     

再谈扩大英语词汇量的途径
