In this article , considering the character of the one - dimensioned continuum and the cross - section , the varied quotiety of the strain can be presented as the mode function to identify the damage . and inversion of the elastic wave is presented to detect the injures when the area is the variable of the inversion , for the pip usually buried under the earth or enwrapped into the protection make the detection difficulty by the mode of vibrancy . the influence of the area must be considered if the exactness is the pre - requisition 在论文中，考虑到压力管道的一维性质，提出用应变模态改变变化率的方法对一维的结构进行损伤识别；同时考虑到在实际的工程和现场测试中，压力管道大多深埋在地下或者有外在的保护膜，不宜进行模态的检测，所以也考虑利用弹性波的方法对压力管道的性质参数和截面性质进行反演识别，从而得到我们感兴趣的东西，达到损伤识别；一般，在利用弹性波反射方法进行损伤检测中，不考虑截面效应对弹性波的衰减影响，这就对损伤检测造成一定的影响，本文考虑截面效应的影响，通过实验来确定截面效应系数。
According to the instance of the arch dam built , take the discount quotiety , the verification flood water level , the frictional quotiety and , the agglomerate force and as stochastic variable quotiety , calculate the reliability index of the abutment with the calculational programme after the average value and variable quotiety is known 对于所取的拱坝实例，以扬压力折减系数，校核洪水位，摩擦系数、 ，凝聚力、为随机变量，在已知其均值并设定变异系数的前提下，利用电算程序计算其坝肩岩体的可靠指标。
Then the system could adopt man - machine intercourse method to carry out model self - learning , correct the budgeting quotiety to piles up experience for the model and increase its optimized degree gradually . all this makes our budgeting process rational , and this improves our enterprise ' s competition ability 然后采用人机交互的办法进行模型自我学习，对模型的预算系数进行修正，使预算模型积累经验，逐渐提高自身优度，使得预算过程更趋合理化，增强企业的竞争力。
This article recommends three kinds of criterion on judging whether the hydropower construction design or optimizing is reasonable , that is " schedule , quality and cost " , it describes mathematics mode and optimizing of concrete mechanization construction system and provides a new method of " combined management of schedule , quality and cost " , and founds the relations of distribute quotiety of the working procedure unit , quality unit , and cost . in the field of management , it indicates the localization of parlance " consumer is the god " , and advances the relations of previous and descend working procedure are the relations between consumer and user . their relations are new relations of serve mutually and create con dition for each other ' s 本文介绍了评价水电工程施工系统设计或优化合理与否的三种标准为进度、质量和成本，描述了大坝砼机械化施工系统的数学模型及优化，提出了“进度、质量、成本联合管理”的新方法，建立了工序单元、质量单元和成本费用之间的分配系数关系，在管理方面，指出“用户就是上帝”这种说法的局限性，提出了上道工序和下道工序之间的关系为顾客和用户之间的关系，它们是互为对方服务，互为对方创造条件的新型关系的观点和方法。
3 . this paper analyzes the existing guide lines of the association of industries , indicates the deficiency of “ the quotiety of middle input ” . this paper founds the guideline of “ the changing quotiety of middle input ” , which could reflect distinctly the change of quantity and structure of the middle input 3 .分析了现有产业关联指标体系,指出“中间投入率”指标在反映内容上的不足,从结构变动的角度提出了“中间投入变动率”指标;该指标能够显著的反映投入产出表中间投入率的变动和中间投入结构的变动。
Thereby drew a conclusion that variability of stochastic variable has remarkable effect on the reliability . and the different stochastic variable has different effect on the reliability while the variable quotiety increasing . the obtained results shown that the calculating method presented in the paper can be widely used in reliability analysis of abutment stability against sliding 从而得到以下结论：在坝肩岩体可靠性计算中，各随机变量的变异性对坝肩岩体的整体可靠性有显著影响，且不同的随机变量，当其变异系数有所增大时，对可靠指标的影响程度是不一样的。
In 2002 , the personal spentable average income was 11500 yuan ; the peasant personal average net income is 5532 yuan ; the city ' s personal average bank saving balance is 13130 yuan ; the engel quotiety is 37 . 9 % and 38 . 9 % respectively for city and township residents ; the living condition and the health of residents are improving ; the personal average expected age is 75 . 4 全市居民人均储蓄存款余额为13130元，城镇和农村居民恩格尔系数分别为37 . 9 %和38 . 9 % ，人居环境不断改善，健康水平逐年提高，人均期望寿命达到75 . 4岁。
