The results indicate that hp can promote the toughness and strength of cement mortar and concrete , and with the increase in hp mixture , compressive strength increases more obviously than bend resistant strength does ; with the hydrosoluble hp fibre added , the microstructure of mortar or concrete will change , the space web structure will be formed , which consists of mixed hydrates and hp films . as a result , the performance of mortar and concrete , with high strength and few apertures , can be improved 结果表明， hp对水泥砂浆和混凝土有显著的增韧、增强作用，且随着hp掺量的增加抗压强度提高的幅度增大，抗折强度提高的幅度降低； hp水溶性高分子纤维的加入可改变混凝土的微观结构形态，在混凝土或砂浆中形成了水化产物与hp膜交织的空间网状结构，使浆体致密，减小孔隙率，从而影响其整体性能。
The growth of gdp , international cooperation revenue ( referring to the revenue from international contracting , labor service and design consulting , inte ) , foreign direct investment ( fdi ) , the share of employment of the tertiary industry ( ter ) , r & d investment by government ( rd ) are found to be the granger causes of cva growth , they driving construction industry ' s development in china . furthermore , gdp , the growth of inte , and fdi are cointegrated with cva and the growth of it , which means a certain trend is kept for a long time between any one of the first three time series and cva . however , cva is the granger - cause of the change of companies " structure , state - owned construction companies having less and less share in employees and output level among all kinds of enterprises 采用unitroottest和grangercausalitytest方法，对中国建筑业经济增长的相关变量进行granger因果分析，结果发现：中国gdp增长、对外经济合作(包括对外承包工程、劳务合作和设计咨询) 、外商直接投资、三次产业人员流动、国家科研投入都是建筑业产出增长的granger因，对建筑业成长有带动作用；其中， gdp 、对外经济合作和外商直接投资的增长分别与建筑业产业增加值增长有协整( cointegration )关系；建筑业产业成长则是其企业结构形态变动的granger因，国有企业在人员结构和产值结构中的比例都越来越小，产业的发展促使多种所有制形式的企业出现，提高市场竞争效率；文章还发现，在宏观经济政策方面，财政政策没有货币政策对中国建筑业的影响明显，虽然近年来积极的财政政策启动了不少大型基础设施项目，但由于“挤西安建筑科技大学博士论文出效应” ， granger检验显示政府的基建支出对建筑业增加值增长促进作用不显著;货币政策却由于对信贷和货币供给的控制而影响着建筑业的产出水平。
3 、 settlement and prototype of the hakka house of huang family . analyzing universal characters of hakka clan and architecture , the connection of consanguinity , historical origin , social organization of huang family , this part discusses the formation , development , structural model of settlement and prototype , cultural character , evolvement of the hakka house of huang family 3 、黄氏宗族客家住屋型制与聚落，在分析了客家家族和建筑的一般性特征以及黄氏宗族血缘关系、历史渊源、社会组织后，探讨了黄氏宗族聚落的形成、发展、结构形态与单体建筑的型制、文化特征及演变。
Based on the chang - yu highway in julin province , this paper focus on gap - graded asphalt mixtures . aggregate grading of the gap - graded hma was designed by means of void design procedure . this paper give out a kind of new gradation of stone matrix asphalt . at the same time , this paper also studies the effect of aggregate size on road - related performance in some different gradings 本文以吉林省长余高速公路为依托，从沥青混合料的结构形态入手，利用体积法，对骨架密实型级配类型的沥青混合料的级配进行研究，提出新型的沥青马蹄脂级配，并针对不同级配的沥青马蹄脂碎石混合料，全面分析了粗，细集料的粒径变化对其各种路用性能的影响。
Secondly , basic patterns of the central space : by means of the analvses of traditional history characters in sichuan . the economy types of threhing ground . and the activities of the public contact , place selecting and structional morphology are reseached . and the fundmental causes connected with the external achitecture substance carriers are reflected 二、传统场镇中心空间的基本格局：通过对四川传统社会历史特色、场镇经济类型、以及人们交往活动特质等方面分析研究中心空间在场镇构成中的位置选址和结构形态，反映出影响建筑外在物质载体形成的深层内在原因。
Based on the analysis of relationship between the deposition rate and the deposition conditions ( the main factor : substrate tenperature , teos temperature and deposition time ) , it is proved that the maximum deposition rate and the optimum surface state , structure of thin films are to be gotten , when the temperature of substrate is 500 to 600 c , the pressure of the reactor is 260 to 400 pa , the temperature of teos is about 60 c , current is 1ml . s - 1 在成膜机理的基础上，通过对不同沉积条件(如沉积温度，物源温度，沉积时间)下沉积速率和薄膜结构形态的测试和分析，我们发现，当系统的实验条件为：基片温度500 ? 600 ，反应室压力260 ? 400pa ， teos的温度在60左右，流量1ml s ~ ( - 1 )时将获得最佳沉积速率和膜的最佳结构形态。
The flexible retaining structure is another important retaining structure in soft soil . the integrated numerical analysis of this retaining structure ( including the methods and theory of calculating active earth pressure under sorts of conditions as well as the calculating method of horizontal stiffness coefficient of bracing structure and the method of deciding boundary condition etc . ) was gived . the effect of all parameters on the characteristics of retaining structure was discussed using methods of sensitivity - analysis 本文针对目前常用的弹性支点法，给出了完整的数值分析方法，包括各种条件下的墙后土压力的计算方法和原理、支撑系统(或锚拉系统)水平刚度系数的计算、边界条件的确定方法等，并以此为基础采用灵敏度系数分析方法讨论了各参数对围护结构形态的影响，指出土体侧向基床比例系数是影响围护结构变形的最主要的参数。
