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。

Relation between geometrical contour error of inner corner and machining condition is investigated by the experimental plan of Taguchi quality design. Through the quantitative analysis, the geometrical contour error is mainly affected by wire tension and flushing pressure. By regression analysis, a mathematical model is established to estimate cutting path error of corner cutting. According to the estimated cutting path error, the program path is corrected.

Aim of the article was to provide a new approach of the fingerprint diagram research for TCM by means of spectrometry, which was capable of indicating the character of TCM. For the purpose of getting indication of NIRDRS convolution fingerprint diagram, the visualization technology was adopted to display the information which have been processed by convolution transform, then color-coded image was displayed in computer and the similarity coefficient was worked out between the fingerprint diagrams by cosine formula. Part one Theory and system design The spectrometry (UV/Vis, NIR, IR) is disadvantageous in the fingerprint analysis of complex systems both its difficulty of specificity and the similarity of TCM.
