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.     

Concrete Evidence Reseach to the Aacepting Insurance Ability of China''s Non-life Insurance Companies

Owning to the ability of accepting insurance enough,it is the foundation for insurance companies to operate in a long-term and steady way,a method to develop sustainably,a reflection of an insurance company's comprehensive competition ability and also a premise for an insurance company to realize developing strategy.Accepting insurance ability is very important in the development and strategic planning for an insurance company.The quantitative analysis is used to analyze the ability of accepting insurance of our country's insurance companies,in another word,the factor(analysis),which belongs to the analysis of diverse statistic,is used.Using the method to give a concrete evidence analysis to the ability of accepting insurance of our country's non-life insurance companies,so that the insurance companies can understand very well to the advantages and disadvantages of the ability of accepting insurance to each other,and as well as supplying a strategic reference for the insurance companies themselves to make decisive planning.     

论乡村产业振兴

当前,全国上下正在全力推进乡村振兴战略的实施。乡村振兴,产业兴旺是重点。如何实现乡村产业振兴、产业兴旺,这是值得研究的紧迫而现实的重要问题。本文首先从乡村产业振兴在乡村振兴战略中的地位与作用入手分析,对新中国成立70年来中国乡村产业发展的历程进行了简要回顾,并将其划分为4个发展阶段：第一阶段：1949—1977年,传统产业缓慢发展;第二阶段：1978—2000年,乡镇企业异军突起;第三阶段：2001—2011年,新型产业不断涌现;第四阶段：2012年至今,乡村产业绿色“转型”。同时也指出了当前中国乡村产业存在的突出问题,即：产业门类少、生产规模小、产业层次浅、产业链条短、生产效率低、特色产业弱、品牌产业缺、产业环境差、产品质量低和缺乏竞争力。最后,针对上述存在的问题,提出了实施乡村振兴战略、实现乡村产业振兴要遵循的6大原则和10项具体措施,以期为推动实施乡村振兴战略做出积极贡献。     

一种快速判别梨果梗的方法

果梗完好与否是梨品质检测的指标之一,因而对果梗情况进行准确判别具有重要意义。为此,通过计算机视觉系统摄取梨的图像,利用图像处理技术提出了一种能快速判别梨果梗有无的算法。该算法的识别正确率达90%,识别速度大约在20～30ms,实现了对梨果梗进行高速检测的目标。     

基于双CAN总线的农用环境参数测控仪的设计

提出了基于双CAN总线的农用模块化多CPU网络型环境参数测控仪的设计,将测控仪分为模糊运算通讯、环境参数测量、输出操作控制、环境参数输入显示4部分模块电路,各模块间通过内CAN总线实现数据交换,测控仪可与上位机间通过外CAN总线实现数据交换.测控仪实现多种参数测控及自校正,通用性强、接线简单、工作可靠、维护方便,易于构成大规模设施农业测控系统.     

深松试验测试系统的研究

利用SDY2101型动态应变仪和Vib’sys处理分析系统组成测试系统,并使应变片构成4个测点,构建4个半桥电路来测量对应处的应变,建立工作阻力计算方程,为深松试验打下基础。为此,介绍土槽试验深松铲工作阻力测试系统及工作阻力计算方法。     

两种有效的预测方法理论分析及实践

预算实际上是一种建模,即根据过去和现在已有的信息建立一个从过去引伸到未来的模型。而时序分析法和灰色系统理论是两种有效的预测方法。为此,介绍了这两种预测方法的原理,并预测了新疆兵团的农机情况。其结果表明:未来10年,新疆农机总动力和投入将会有较大幅度的增长,而农业机械化程度将趋于最高值。     

污泥农用资源化研究现状

污泥中富含N,P,K及有机质,是天然的有机肥料。因此,污泥的农用是污泥处置的最佳途径。污泥农用的主要途径有农田施用、林地施用、研制复合肥以及作为土壤改良剂。为此,结合实例阐述了我国污泥农用资源化处置现状及未来发展趋势,并指出了污泥农用的发展方向。     

木质素复混肥对土壤脲酶活性的影响

通过盆栽试验,研究以亚铵法制浆废液氨解产物为原料研制的复混肥对土壤脲酶活性的影响,以确定其对肥料缓释性能的影响.试验结果表明,以亚铵法制浆废液氨解产物为原料研制的复混肥,能够抑制土壤脲酶活性,降低氮素的释放速度,从而提高肥料的利用率,旨在以亚铵法制浆废液氨解产物研制缓释混肥提供理论依据.
