南川河河流健康评价

河流健康评价研究对河流环境的治理与保护具有重要的指导作用。运用模糊层次评价法确定了河流健康系统中各级指标的权重,然后通过引入可变模糊集理论建立了河流健康评价的模糊层次与可变模糊集(FAHP-VFS)耦合模型。进而以西宁市南川河为例,利用20个定量、定性指标组成的河流健康评价体系,从地貌、生态、水文特征3个方面进行了健康评价。结果表明,南川河总体上处于健康状态,但有部分河段处于亚健康状态,因此应进行分段整治。     

凌津滩电厂水轮机转轮室换型改造

针对凌津滩电厂4#~9#机转轮室产生裂纹的现象,就转轮室的结构及特点,设备的运行工况以及同类机组的类比等,对转轮室各个部位裂纹产生的原因进行了全面和深层次的分析,并根据分析的结果和设备运行现状,进行了一台机组的转轮室换型改造。通过新旧转轮室的结构特点对比以及强度的分析计算,经过一年的运行观察,新转轮室能够很好地确保设备的安全稳定,彻底解决了转轮室裂纹问题。     

什么决定了中国商业银行的高盈利

本文分银行和省际两个层面探讨了中国商业银行高盈利的原因。研究结果显示,经济持续良好的增长使人们的收入不断提高,人们对银行产品和服务的需求日益高涨,而政府对存款利率和民间金融等的严格控制,使商业银行处于供不应求和相对垄断的地位。这些是商业银行利润持续走高的最主要原因。虽然2003年开始的银行业改革使银行的市场化程度大幅提升,但是中国的商业银行仍不是自主经营的真正企业。银行的利润主要是宏观和政策环境给予的,这也是银行的高利润备受市场批评的主要原因。     

垂向平均含沙量计算方法初探

从2种悬沙垂向分布公式出发,结合对数流速分布公式,导出2种常见垂向平均含沙量计算方法的比值关系表达式。讨论了2种方法的区别与联系:两者不一定相等,比值可以大于1,也可以小于1,当近底相对水深稍大(如大于0.01)时加权平均含沙量小于算术平均含沙量,与实际相符;2种垂向平均含沙量的差异主要由悬沙及流速垂向分布不均匀性引起。对2种方法的实际应用情况进行了初步分析。     

华北平原典型区域土壤凝结水观测及其影响因素研究

为查明华北平原典型区凝结水发生情况,采用称重法进行了土壤凝结水的初步观测,结果显示:每日14时至次日10时均可观测到凝结水的生成,研究区凝结水大部分来自于大气中的水分,极小部分来源于下层土壤,其主要凝结集中在表层0～5cm范围内,共占观测深度总凝结水量的50%左右。根据土壤凝结水形成的影响因素分析结果,较低的温度、较高的相对湿度和无风的条件有利于凝结水的生成。

Cold-humid effect of Baiyangdian wetland

Data support for wetland protection function evaluation can be provided by quantitatively analyzing the ability of regulating the regional climate of the wetland ecosystem. In this study, the cold-humid effect of the Baiyangdian wetland was analyzed by comparing the meteorological conditions of the Baiyangdian wetland and its surrounding areas. Meanwhile, the regulatory functions of the Baiyangdian wetland for the processes and magnitudes of temperature and relative humidity from August to October 2008 were evaluated. The results show that daily mean temperatures in the Baiyangdian wetland were lower than in the surrounding areas, and that temperature differences mainly occurred in the daytime but were not obvious at night. Diurnal temperature ranges in the Baiyangdian wetland were lower than in the surrounding areas, and the higher the diurnal temperature range in the surrounding areas was, the stronger the regulation ability of the Baiyangdian wetland. Compared with the surrounding areas, the decline of the daily minimum temperature in the Baiyangdian wetland was gentler, and the mean relative humidity there was higher. The present findings indicate that effects of the Baiyangdian wetland on climate and humidity regulation are significant.     

利益相关者与企业伦理关系分析

Responses to risk in tournaments

Due to their inefficient use of information, promotion incentives, which can be modeled as tournaments, can induce sub-optimal actions on the part of managers. This is a problem for firms because it leads to choices that do not maximize profit. This also can pose interpretation and comparison problems for research studies that employ tournament incentives. We demonstrate a situation where tournament incentives eliminate the effects of project risk on managers’ decisions as concerns with winning take precedence over concerns of maximizing expected profit. We also report the results of an experiment and find actual behavior to be fairly well explained by theoretical predictions. However, we find systematic deviations that lead to decisions that are more consistent with profit maximization than the economic theory predicts.     

振兴东北经济的税收政策思考

自2004年振兴东北的序幕拉开至今,国家对东北地区出台了一系列税收优惠政策,通过对税收政策的归类、分析表明,诸项税收优惠政策中照顾性多、激励性、导向性的极少,鉴于此根据比较优势理论重新审视东北地区的优势产业,以此理顺税收激励政策.
