双弧焊对10Ni3CrMoV钢性能影响的研究

对921A钢进行了热模拟试验,同时对该模拟试样作了50℃冲击功测试,结果表明,试验钢经过双丝焊接热循环后,热影响区各区的低温冲击功普遍低于母材。将冲击功最低试样做光学显微组织分析,结果表明试样的组织由母材的回火索氏体组织转变为贝氏体+粒状贝氏体+少量铁素体;将其冲击断口做电子扫描电镜分析,结果表明整个断口主要为放射区,只有少量纤维区和剪切唇区主要呈解理特征;验证了调整双丝间距和焊速得到合理的热循环是取得优良焊接接头的保证。     

我国大气污染治理全局优化省际合作模型

首先,结合目前我国大气污染的实际情况,提出了通过省际合作达到大气污染治理的两个基本假定。其次,通过构建全局优化模型和节余成本加权分配法,建立了大气污染治理全局优化省际合作模型。最后,以2009年SO2去除为例进行实证分析,结果显示了大气污染治理全局优化省际合作模型的有效性和实用性,而且模型的最优化模拟结果可以作为国家决策的重要参考,促使各省份合作共赢。     

山西成家庄煤矿矿井充水因素分析及水害防治措施

矿井水害的预防预报是指查清矿井水文地质条件,对水害做出分析判断。本文以山西成家庄煤矿防治水为例,分析了矿井充水因素,以理论结合实际,为预防矿井水害提供依据。     

组织创新的消极影响:创新研究中的盲点

创新带来的消极影响开始引起学术研究者和管理实践者的关注。从组织创新的概念界定出发,辨析创造力和革新的区别与联系,综述创新在个体层面、团队层面以及组织层面可能产生的消极影响,从前因变量和调节变量两个方面探讨创新产生消极影响的原因,指出未来研究不应忽视创新的消极影响,而应更加科学地解释组织创新的效能。     

强耦合氢等离子体中Be~（3＋）的结构和辐射性质研究

采用离子球模型研究了强耦合氢等离子体中杂质Be3＋的原子结构和光谱性质随离子球大小的变化规律.结果表明,强耦合等离子体的屏蔽效应对其中的原子结构和光谱影响很大,而且不同模型给出的结果有很大的差别;在离子球模型下,类氢的轨道电离能随着屏蔽效应的增强而单调减小,轨道的简并度解除,但是随着屏蔽效应的增强,轨道将二次简并,轨道能级关于角动量发生发转;不同主量子数n两能级之间辐射的光谱随着屏蔽效应的增强先红移而后蓝移,在非相对论情况下,屏蔽效应引起同n轨道能级劈裂,辐射出新的光谱,该光谱随着等离子体效应的增强先蓝移后红移,经过再次简并后继续蓝移,直到不再辐射出光谱为止;轨道之间的重叠积分由于等离子体屏蔽效应先减小而后增大,从而振子强度随着等离子体屏蔽效应的增强先减小而后增大.目前的计算数据与可查的数据非常符合.     

论庄子的逍遥思想

＂逍遥＂是庄子思想的核心。庄子所谓的逍遥,是一种远远超越现实世界的理想境地,体现了庄子面对不完美世界的一种至臻追求。这种境界的达到,需要极深的功夫,非一般而能为之、一蹴而能成就。对《逍遥游》的深入解读,是了解庄子逍遥思想内涵的重要手段和主要途径。     

浅谈企业研究与开发的管理

建立在现代项目管理理论基础上的企业研究与开发的管理重点是通过时间控制、成本控制来提高R&D的投入—产出比,进一步提高R&D的绩效。     

Labor Unemployment Concern and Corporate Discretionary Disclosure

We investigate how firms strategically vary their disclosure policies in response to labor unemployment concern. Using changes in state unemployment insurance laws as exogenous variations of labor unemployment concern, we show that firms provide more bad news forecasts when unemployment concern is low. This relation is stronger when firms are financially constrained, when CEOs and CFOs have higher equity incentives, and when workers are likely to be affected more by unemployment. Our findings are not driven by earnings management reversal or underlying performance changes, and are robust to a battery of identification tests. Finally, we find a similar effect of unemployment concern on disclosure using the tone of 10‐K and 10‐Q filings as an alternative proxy for corporate disclosure. Overall, our findings suggest that labor unemployment concern is an important consideration for corporate discretionary disclosure.     

探析我国当前通货膨胀的成因与治理对策

从2010年7月开始到2011年6月,我国衡量物价水平的两大指标CPI、PPI持续上涨,通货膨胀日益加剧,如何治理通货膨胀成为我国经济发展的重中之重.本文总结归纳了我国本轮通货膨胀的特点,以及引发我国通货膨胀的国际和国内因素,并在此基础上有针对性地提出了相应的综合性治理措施.     

Popular Geopolitics,Audiences and Identities: Reading the ‘War on Terror’ in the Philippines

Audience research has traditionally been neglected within the subfield of popular geopolitics. However in recent years, geographers are increasingly focusing on the making of geopolitical meanings by audiences as they consume popular culture and related texts. Drawing on recent assemblage thinking in geopolitics, this paper argues that audiences form part of the animators of a network that links the human body with places, environments, objects and discourses related to geopolitics. By investigating Filipinos’ critical readings of and engagements with the ‘war on terror’ in Mindanao as represented through the national newspaper, the Philippines Daily Inquirer, the agency and power of audiences in the creative enactments of geopolitics and geography are illuminated. As such, understanding the complex interactions between popular media and its audiences can prove useful in casting insights into the everyday, geopolitical ‘playing out’ of issues of terrorism, violence and peace in the Philippines context and beyond.
