牛肺疫临床症状及综合防治

牛肺疫又被称为牛传染性胸膜肺炎,是由肺炎支原体感染引发的急慢性呼吸道疾病,临床上主要表现为呼吸急促,呼吸困难,从鼻腔中流出脓性分泌物,主要对患病牛的肺脏、胸膜和淋巴结造成危害,典型的临床特征是肺小叶浆液性肺炎和肺实质纤维素性肺炎,被国际兽医局划归为A类动物疫病,我国将其划归为一类重大动物疫病,发生流行后,需要执行严格的扑杀、无害化处理制度,逐渐净化牛群,避免疫情进一步扩展蔓延到造成更为严重的经济损失。该文主要论述牛肺疫的临床症状和综合防治措施。     

基于灰色关联法的小型农田水利工程建设项目绩效评价研究

运用灰色关联法原理,采用均方差法计算指标权重,根据近年来湖北省进行小型农田水利工程建设项目绩效评价的实际情况,建立了小型农田水利工程建设项目评价定性定量混合指标体系和模型,应用该模型和方法对湖北省2012年第二批20个小农水重点县工程建设项目进行了评价(作为研究,各县、市名以汉语拼音字头代替)。结果表明:LHK、SSS、ZJS、DJK、XTS等14个县为优秀,XCX、TMS、JSX等5个县为良好,CYX为一般,无及格等级的重点县。评价结果与实际基本相符。证明本文所提出的模型和方法可应用于实际,是一种快速便捷的评价工具。     

灰关联决策在水质面板数据处理中的扩展及应用

针对面板数据灰色关联决策分析评价问题,在经典灰色关联分析和灰色综合评价方法的基础上,构建面板数据灰色关联决策评价模型。将灰色关联决策方法扩展到面板数据分析中,解决了小样本面板数据的灰色评价分析问题。将这种方法应用于水环境面板数据质量评价中,经实例计算验证了面板数据灰色关联决策评价模型的稳定性、合理性和实用性,为水环境面板数据质量分析评价提供了可行的计算思路和方法。     

A Furry Synthetic Evaluation Model in Capital Structure Decisions

This paper analyzes the limitation of regarding the weighted average cost of capital as the optimal standard of capital structure in the traditional capital structure decision-making method, and analyzes the view that the capital structure is affected by many factors,such as earning power, long-term stability of operating, the attitudes held by owners and operators, the attitudes held by creditors and financial risk. With the example, the affecting factors of the capital structure is analyzed. The fuzzy synthetic evaluation model are employed to decision-making of the capital structure. This article also shows the key point of its application.     

Real Estate Brand Evaluation

At present, in the evaluation process of the real estate value the material form is mainly concentrated on, while the value brought by the real estate brand are usually neglected. In this paper, considering the particularity of the real estate brand evaluation, the method of network analysis is adopted. In the evaluation process, the evaluation method of excess income law are developed by leading the thoughts and methods of the fuzzy set theory, and a systematic assess model is found. Then, an example is given as illustration. At last, the appraise about the application of the model is made.     

Selecting Bid with Reasonably Low Price Without Bottom Price Based On Sector Estimate

For raveling out the main shortage of tendering which is the reasonable sector is unreasonable of making the bid evaluation uncertain. In order to eliminate subjective factor, this paper quantificationally analyses the price in bidding and establishes the sector selecting bid model based on the sector estimate idea, which tries to provide a new method and academic basic for determining the reasonable sector. Finally, the article gives an example to prove that the model is feasible and effective and it tries to ensure the bidding assessment public, equitable and just.     

Synthetic Evaluation of Talent Effectiveness Considering Talent Structure

Based on the widening of definition of talent effectiveness, using the indexes of talent structure and economic output types, many indexes of talent effectiveness are built up. A synthetic evaluation of regional talent utilization efficiency is presented based on principal components analyses. The result indicates that the talent utilization efficiency in east China is higher distinctly than in middle and west China and the talent utilization efficiency in middle is close to in west China without obvious hierarchy distribution     

A Method of Adaptive Fuzzy Classfication on Rockmass Blast Ability

This paper presents a series of targets which are usefull for engineering.The paper also presents an adaptive weight function according to the fail mechanism of rockmass and a fuzzy aynthetic evaluation medel on rockmass blast ability.The model is applied to evaluate the blast ability of rockmass in an engineering and the result shows that the model is effective.     

Analysis of Social Appraisal Index System in Public Project

The social evaluation theories of public project still have not been standardization today, and have effects on the process of the construction to city. One of the main reasons lays in that the index system, about the social evaluation theories of public project, connects with many fields, has many non-economic index and difficult in measuring the every index. This article is to mark off the main factors involved in social evaluation effectually, to set up index system of social evaluation practically, and to settle firm ground for methodology and theory of public project.
