查询词典 arithmetic data

Several cluster validity measures have been proposed for confirming the optimal k value. However, the existing methods may not work well for the following two kinds of data sets: the data set containing cluster groups with different densities and the data set in which the cluster groups are extremely close to each other.

Results and conclusion: the mathematics mechanism theory of Nervous system about their basic data and interconnection may be expressed by the neural information encoding formulation: x1=m1a/b and y1=n1c/d、x2=m2b/a and y2=n2d/c The neural information encoding formulation have novenary and undecimal and many other scales. All Periphery Nervous- Cerebral Cortex- Sympathetic Nervous have obvious and invisible encoding data in 2 kinds: yin and yang ,2kinds:ambulatory and static state, 3 grades: Max Med and Min. they all exist in obvious or invisible type. Just like a cogwheel system and there is a inter-meory function among the data.

The elastic stress diagram design method is behind the times and cant meet the command in practice.In the paper the author collected and analyzed a large amount of data about the SLRCP on several typical domestic model experiments and the projects in practice. By summarizing and analyzing the data, the author set up a typical computing model and analyzed the model by the software ANSYS, by reading the output data of the stress and the crack from the program, combined with the experimental results, the author summarized the destroy procession of the stock. The paper also discussed the influence of other main factors to the crack and the stress besides the internal water pressure, such as the concrete material, the dimension of stock and the way of laid-out steel bars.

本文通过对大量实际工程中的坝后背管资料的收集、归纳和分析，选取了具有代表性的计算模型；用有限元软件ANSYS计算了典型坝后背管结构在实际内水压力作用下的应力分布和裂缝发展情况；以国内几个有代表性的模型试验和有限元计算的成果为依据，分析了在内水压力作用下钢衬钢筋混凝土压力管道管壁裂缝的特点，并尝试总结出此种管道的裂缝出现的原因及其发展规律，同时确定了坝后背管结构极限状态的新的定义方式——以坝后背管的裂缝宽度来定义。
