Earthquake Resistant Engineering and Application of Seismic Zonation Map of China

China is a country with high seismieity. It is very important for industry and structure to fortify against earthquakes. In this paper the outline of seismicity in China, the criteria for fortification against earthquakes and the contents of seismic zonation map of China are described. The contents of seismic safety evaluation for major construction projects, such as large dams, large bridges, long distance pipe lines for transporting oil and natural gas, nuclear plants, petrochemical enterprises and so on, are presented. Some geological disasters caused by destructive earthquake, such as earthquake-caused collapse and landslide, liquefaction of saturated soll and earthquake fault and so on, are also presented. Preventive countermeasures for these disasters are discussed.     

THE INDUSTRIAL UTILIZATION OF CHEMICAL MODIFIED AGRICULTURAL RESIDUES

INTRODUCTIONToday, the world's industry is utilizing less than 10% of biomass of raw materials from plantation [1]. Agricultural residues, such as cereal straws are important and abundant renewable organic resources of energy and production of a diversity of chemicals, including ethanol production [2], activated carbon [3] and ion exchangers [4]. Many other applications for Cereal straws are in the process of being developed.In china, wheat, maize and sorghum are the three major crops, w…

Research on a New-style Pipeline Inspection Robot System

IntroductionRecently pipe is used widely on the industry,agriculture and daily life. Natural gas and oil supplybecomes one of the fundamental public services and itsimpact on the urban infrastructure is getting larger. Theurban oil/gas pipelines, as they are buried under theground, are prone to external corrosion usually derived bymoisture and chemical agent in soil, which causes materiallosses of the pipe wall. Also, cracks in the welded regionand the da…

基于元胞自动机的多自主体人员行为模型及其在性能化设计中的应用

目前性能化设计规范一个最主要的特点是从强调财产保护转变到强调生命安全保护，因此对建筑物内人员行为特征和运动规律的研究正越来越受到人们的重视。元胞自动机模型在交通流研究中的应用已经开展多年并取得了很多有用的成果，但涉及人的行为特征的研究往往十分复杂，在这方面利用自主体来研究具有较大的优势。给出的模型结合了这两方面各自的优势，是在元胞自动机交通流、行人流基本框架上建立起的多自主体人员行为模型，它对评估建筑物的设计方案具有很好的参考作用。     

通道不一致性、互耦对最优阵列处理器的影响

本文研究了通道幅相不一致性、互耦这两种误差对最优阵列处理器性能的影响。理论分析结果表明,对于只利用干扰加噪声协方差矩阵求逆的自适应方法(简称NAMI法),当干噪比(JNR)较大时,这两种误差不会导致零点位置的漂移,但零点深度有所变化;对于信号加干扰和噪声协方差矩阵求逆自适应方法(简称SPNMI法),当信噪此(SNR)较小或较大时,零点位置变化不大,但性能损失比NAMI法严重得多。如果能加以补偿,则SPNMI法与NAMI法有相同的结果。我们用矩量法计算得到的互耦矩阵对此进行了仿真模拟,实验结果证明了理论分析的正确性。
