The principle of the survey site selecting is described first and then the basic information of the survey sites selected is provided in details , including the location , size , circumstance , etc . the survey method , the choice of survey time and the method of data collection and reduction are described . then regression models were developed after choosing feasible independent variables . the trip generation rates for autos , bicycles , and transit riders were derived based on statistical analysis of the three land uses respectively 然后,阐述了现场调查的方法,内容,调查时间的选择和调查数据的汇总整理,并对整理后的调查数据进行了统计分析,分别给出了这三种用地类型在早晚高峰时段的出行生成率,并在可能的情况下,给出了相应的回归曲线和回归公式,并对各个分析结果进行了解释分析。
The comprehensive geological characteristic has been fully studied in this paper . on the basis of this , closely combining production practice , the favorable gas developing regions have been determined with the methods of sedimentary facies and combination of generation , reservoir and caprock , and logging parameters interpretation maps and regression formulas have been established with logging data , as well as reprocessing , interpretation and identification of gas reservoir have been done with computer . integrating the information and results of geology , logging , testing and geophysics , the gas reservoir distribution regularity of structure of no . 1 sebei has been described and reserves in place of no . 1 ' sebei gas field have been recalculated , which have provided a basis for next step of development in research area 在近十多年，通过提高地震资料处理精度、淡水聚合物泥浆的应用、数字测井技术的运用、并加强了低电阻层和差物性层的试气及气田扩边钻探，大大提高了对气层的识别，大量增加了气层的层数和厚度，扩大了气田的含气面积，使气田储量通过多次复查核算仍在不断增加本论文充分研究了青海涩北一号气田天然气地质综合特征，并以此为基础紧密结合生产实践，应用沉积相与生储盖组合等方法确定气藏有利发育区带，应用测井资料建立测井参数解释图版并回归公式，应用计算机重新处理、解释和识别气层，综合地质、测井、试井、物探等多方面信息与成果，描述了涩北一号构造的气层分布规律，重新计算了涩北一号气田的地质储量，为研究区下一步开发提供了依据。
To generalize the eccentricity ratio effect on ultimate tensile strength of ductile plates , the elesto - plastic finite element method is undertaken and a mathematical transition expression of normalized ultimate tensile strength of center - cracked , eccentrically cracked , edge - cracked plates is accordingly deduced 对于偏心裂纹延性板，采用弹塑性有限元进行了大量的组合计算，分析了相对裂纹长度、材料屈强比和裂纹偏心度对板的拉伸极限强度的影响，并给出了方便计算的回归公式。
The results indicates that the cubic logarithm polynomials can accurately reconstruct the raw thermal images in the experiment , and can effectively suppress the interference to defect recognition caused by random noise and uneven heating in the pt testing of composite laminates ; the digital images from data reconstruction have clearer defect display or higher defect resolution than the raw thermal images , and the quadratic coefficient image of cubic logarithm regression shows the highest snr 结果表明利用三次对数多项式回归即可精确地重建本次实验的原始热像，同时能有效地克服复合材料层压板脉冲热像检测中随机噪声和加热不均效应对缺陷识别的干扰；经过数据重建后所作的数字图像比原始热像有更高的缺陷显示度或分辨力，其中以三次对数多项式回归公式中的二次项系数所作的数字图像的信噪比最大。
Three models are established first by linear regression analysis with the experiment data of practical ship plate . through comparisons between the three models obtained , the effect of each parameter on the local contraction , is examined , the conditions of application are estimated , and explanations are given to the error induced in the models obtained . 3 首先选择影响成型的主要变形参数，运用数理统计原理及逐步回归分析方法，对945钢板测试数据进行回归分析，建立了三种变形参数的回归模型，最后比较分析这三种回归公式的回归效果，考察回归公式中各变形参数对变形量的影响程度，给出适用条件，分析误差项产生的原因。
