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。     

旅游公共服务质量的提升:游客导向和创新导向的驱动作用

在将旅游业发展成为国民经济的战略性支柱产业和人民群众更加满意的现代服务业的过程中,旅游公共服务发挥着重要作用。对于政府管理部门内部有哪些因素会促进旅游公共服务质量的提升,学术界鲜有实证研究。本文从旅游行政管理部门的角度出发,构建了游客导向、创新导向、跨部门协调对旅游公共服务质量的影响模型。对广东省32个主要客源市场的旅游行政管理部门的309位工作人员进行了问卷调查,探讨旅游公共服务质量提升的驱动因素。结构方程模型结果显示,游客导向、创新导向和跨部门协调都有助于旅游公共服务质量的提升,跨部门协调中介游客导向对旅游公共服务质量的影响。本文在理论上弥补了旅游公共服务质量前因研究的空白,对旅游行政管理部门如何更好地提升旅游公共服务质量具有借鉴意义。     

怎样认识和把握我国现阶段的个人收入分配制度

为了准确地认识和把握我国社会主义初级阶段个人收入分配制度的理论指导与政策规定的理论内涵 ,需要我们就现阶段个人收入分配制度的理论与事实依据 ;社会主义市场经济条件下按劳分配的特点 ;如何理解确立劳动、资本、技术、管理等生产要素按贡献参与分配的原则 ,以及保护合法的劳动收入与合法的非劳动收入等诸方面进行探讨。     

The suspension of borrowing: an implicit penalty for loan default under imperfect information

A credit seeker may be suspended from borrowing for a period of time due to a previous default. Such suspension is widely used in bank lending through credit check. Our work analyses the effects of suspension on the investment choice of borrowers under uncertainty and on the lending policy of banks facing asymmetric information. We show that suspension should be tightened at low loan rates, but loosened otherwise, to improve the repayment performance of borrowers. We also show that although credit rationing may not be completely removed due to imperfect information, the excess demand for credit or transitive waiting in the market can actually be attenuated by such efficient use of suspension. Our theoretical predictions are consistent with observed cyclical patterns of changes in lendingrates and suspension severity.     

从资金流量表看中国的高储蓄率

近年来,随着中国经济的飞速发展,一直保持在高水平上的中国储蓄率受到了越来越多国内外经济学家的关注。比较有代表性的看法把中国的高储蓄归因于中国金融市场的不发达和中国的文化背景,即传统上中华民族崇尚节俭,中国居民缺少多元化的投资方式。另外,也有不少人认为,由于中国社会保障制度还不够完善,住房制度改革后居民的购房需求以及对子女教育支出的预期、未来收入的不确定性等都使中国居民的预防性储蓄大大增加(如:齐天翔,2000;于永胜,2003;施建淮、朱海婷,2004)。中国储蓄率为什么居高不下?本文试图从国民收入分配的角度寻找答案。一、…     

动物产品中17种有机氯、拟除虫菊酯残留同时测定的全自动固相萃取技术研究

本研究针对目前动物产品中有机氯、拟除虫菊酯残留检测干扰严重,必须进行繁琐的酸消化、硫酸磺化样品前处理问题,应用全自动固相萃取技术对动物产品中17种有机氯、拟除虫菊酯残留检测的样品前处理方法进行了系统的研究,对提取溶剂、固相萃取柱、淋洗液、洗脱溶剂及仪器分析条件进行了优化选择,建立了高效、快速、经济、安全的动物产品中有机氯、拟除虫菊酯残留同时检测的全自动固相萃取净化方法.经不同检测单位验证,该方法的加标回收率介于78.6%～103.0%之间,精密度(CV)为2.7%～12.1%,测定低限为0.005～0.010mg/kg,满足出口检测要求.
