Three Turns of Contemporary Architecture and the Chinese Traditional Thoughts

Significant changes have taken place within the contemporary architecture since the 20th century: firstly the architecture turns from "thing" to "nothing",secondly the experience of architecture turns from logic to essence intuition,and thirdly the architecture turns from noun to verb,from which we find in surprise the sparks of the Chinese traditional thought which criticizes all the ready-made,especially the conceptual thought with its happening and generation,and shows a new non-subject-object-dimidiate,non-logical and fundamentally non-metaphysical perspective in theory.This made it possible for us to reconsider and reinterpret the contemporary architecture from a more original new perspective.     

Risk Decision-making Method of Slope Resistant Engineering

Considering the character of slope resistant engineering invest benefit, in line with security and economy balmaced, combining initial investment and anticipated hazard loss, disaster resistant engineering should be satisfied with the criterion of minimum cost. Decision tree model is adopted as analyzing means, and risk decision-making of slope design is carried out. Project input-output radio adopting dynamic analysis can reflect project investment benefit more accurately. At last this paper analyzes some questions in process of slope resistant engineering with benefits enumerate.     

Engineering Calculation Mode Based on Reformative B/S Architecture

Engineering designed mode has entered a new stage because of the development of network. New calculating system based on network appeared. By analyzing the common B/S architecture, this paper brings forward an reformative architecture based on Web services and ASP. NET in order to build the new mode of engineering calculation. It can fully implement the sharing of the resources and provide the engineering designers a wonderful calculating environment, and the working eifficiency of designers can be enhanced.     

图热点和树结点双向驱动汽车备件系统可视化研究

针对国内汽车企业不具备整车齐全的三维CAD模型的实际情况，提出一种基于动态装配图热点和产品结构树结点双向驱动的备件数据可视化管理方案，在Delphi开发平台上将Action Script技术和ActiveX技术集成到可视化备件管理系统中。详细阐述了图热点驱动和树结点驱动的程序实现流程．给出了动态装配图、装配结构树和界面数据窗三者之间的联动关系，实现两种驱动的等效性。为了便于用递归算法遍历结构树，对复杂网状结构的零部件从属依赖关系进行规范化处理．使之成为树形结构。采用约束递归迭代，对一次性加载零部件的层数和范围进行约束，用统一的虚拟临时结点代替当前非叶子结点的子结点，实现整车装配关系结构树构造过程的优化。     

单株幼龄苹果树修剪仿真研究

修剪是果树生产中重要的技术手段,要想研究更加合理的修剪技术体系,就必须保证能够对修剪反应有准确、直观和及时的判断,而仿真模拟技术提供了这种可能。以幼龄苹果树为研究对象,采用不同修剪处理对比的方法,在田间试验的基础上,总结修剪反应规律,构建苹果树结构和修剪模型。在此基础上基于Qt框架和OpenGL图形库,开发了单株苹果树修剪仿真软件平台。结合优化算法,通过仿真平台模拟了给定生产目标的修剪方案优化,优化结果对虚拟学习和实际生产提供了可视化指导。     

Irrigation scheduling in a mature peach orchard using tensiometers and dendrometers

Three trickle irrigation schedules, two of which were scheduled according to soil water potential ( soil) (tensiometer method) and daily stem contraction (DSC) (dendrometer method) respectively and the other one was a schedule of restricted water supply, were applied to a mature peach orchard.The annual water application based on soil was greater than that based on DSC. However, tree growth, fruit size and leaf water potential (leaf) on the trees in the dendrometer scheduling plot did not differ from those in the tensiometer scheduling plot while the premature fruit drop and fruit bud initiation were greatly different. The restricted water supply treatment limited significantly both tree and fruit growth. In addition, the lower leaf was observed on the trees in this plot.Further study shows that use of the dendrometer method for scheduling irrigation satisfies the water needs of the plant and that the tensiometer method is less accurate.Abbreviations leaf leaf water potential - soil soil water potential - DSC daily stem contraction - LVDT linear variable displacement transducer - PET potential evapotranspiration
