The Reformation of the Construction Employment System and Building a Harmonious Society

Construction industry is not only the pillar industry in national economy,but also the typical industry with intensive labors.As a major part of the construction industry,the Construction Employment System(CES) is an important factor of the market order,as well as the quality,the safety and the development of the industry.It is also an important part for building a harmonious society.It concerns the social harmony,political harmony,societal harmony,cultural harmony,urban-rural harmony,etc.However,at present,there are still many problems in CES that might influence the harmonious society building.This paper advises to speed up the reformation of CES,to establish and consummate the system of construction labor subcontract,to develop vigorously labor subcontract corporations,to improve the quality of the labors,to ensure the rights and interests of the labor.     

Inspiration to Reuse of Old Industry Building with SOHO

This paper analyzes the SOHO and the reuse of old industry building, and deeply explores the creation and application of SOHO mode in the reuse of old industry building, furthermore, it points out the four inspirations to the reuse of old industry building, at the end, a general judgment of the development logic of SOHO is given.     

Utilizing Industry Solid Wastes as Resource of Building Material in Chongqing

To embed or heap industry solid wastes somewhere will occupy the earth and pollute the environment seriously. So utilizing the industry solid wastes as regeneration resource is important for sustainable development of city. Based on application and research for years in utilizing industry wastes and widely investigation, the produce status of industry solid wastes in Chongqing such as fly ash, desulfuration gypsum, blastfurnace slag and chromium slag are introduced. At the same time,this paper introduces application and research on these wastes in field of building material in Chongqing. Analyze problems and countermeasures during utilizing industry solid wastes as regeneration resource in Chongqing. As a further the prospect of utilizing industry solid wastes as regeneration resource of building material is discussed.     

A New Method for Parameterized Design of Metallic Doors and Windows

According to the graphics characteristics of metallic doors & windows design and based on the research of graphics dimension restriction problems. This paper provides a new method for parameterized design of metallic doors & windows in virtue of expression solution. In this method, the restrictions of graphic elements have been changed into the parameter expressions of sizes and positions of graphic elements. Through the calculation of such expressions, the parameter driven method has been reached. Thus the parameterization of graphics can be easier and quicker than before. It can be used to setup the open parameterized graphics libraries.     

基于KPCA-WLSSVM的建筑能耗预测模型

为降低建筑能耗影响因素间复杂相关性对模型性能的影响,建立了一种基于KPCA-WLSSVM的建筑能耗预测模型。利用核主元分析(KPCA)对输入变量进行数据压缩,消除变量之间的相关性,简化模型结构;进一步采用加权最小二乘支持向量机(WLSSVM)方法建立建筑能耗预测模型,同时结合一种新型混沌粒子群-模拟退火混合优化(CPSO-SA)算法对模型参数进行优化,以提高模型的预测性能及泛化能力。通过将KPCA-WLSSVM模型方法应用于某办公建筑能耗的预测中,并与WLSSVM、LSSVM及RBFNN模型相比,实验结果表明,KPCA-WLSSVM模型方法能有效提高建筑能耗预测精度。

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。     

简单屋顶绿化的滞蓄特性

设计了模拟降雨与数据采集系统,研究了短时强降雨下简单屋顶绿化基质(配比：陶粒57.0%、草炭41.5%、保水剂1.5%)的降雨产流过程,基于37次模拟降雨实验,归纳了降雨产流的一般过程、规律和特性,分析了降雨强度、基质厚度和基质初始含水率对简单屋顶绿化滞流蓄水特性的影响。结果表明：基质厚度和基质初始含水率对简单屋顶绿化的蓄水特性有显著影响,基质初始含水率越低、基质厚度越厚时蓄水特性越佳。建立了产流时间数学模型,简单屋顶绿化降雨产流时间与降雨强度呈负相关,同时也受初始含水量和基质厚度影响。随着干湿循环次数增加,基质的厚度总体呈现下降趋势,储水性能逐渐下降,延迟产流时间逐渐缩短。
