Because limited by the sampling channel of transient electromagnetic measuring depth fieldwork curve ( generally 20 ~ 40 channels ) , the smoothing degree of fieldwork curve is not very good , it make against the differential imaging treatment . in order to hold the continuous change characters of the curve and seek the voltage exactly , we use the thrice spline insert number function to reconstruct the fieldwork data ; 4 ) t ； 3 .由于受瞬变电磁测深实测曲线取样道的限制(一般为20 ~ 40道) ，实测曲线光滑程度较差，不利于微分成像处理，为了更好的把握曲线连续变化的特征及准确求导，采用了三次样条插值对实测数据进行重构;续

It is based on a set of practical data in some area . the nonlinear least - square method is used to work out the parameters of the mobile communication channels " model , and then the error sequence comes into being . the noise ' s model of automobile that can reflect the random characteristics of the noise is also founded 本论文采用简单分群的markov二状态模型建立移动信道概率统计模型，从某一移动信道实测曲线出发，利用非线性最小二乘法得出状态模型参数，从而获得移动信道的差错序列；本文对汽车噪声的产生以及它对信号的影响进行了详细的分析，提出了汽车噪声模型；并且采用尖脉冲模拟汽车点火噪声脉冲，实现了噪声对信号的随机干扰，形象地反映了移动信道中信号的叠加过程。
The model ' s parameter was applied to gain the theoretical stress - strain - volume change curves and used to compare with the experimental stress - strain - volume change curves to verify the rationality of it . the newly proposed model is applied in the finite element program , the new program was applied in finite element stress - strain analysis of zipingpu reservoir concrete faced rockfill dam , and at the same time compare with the result of the widespread model ( such as e - u model ) to test and verify its rationality initially 利用求取的模型参数得出理论拟合曲线，进行理论拟合曲线与试验实测曲线比较，验证建议模型的合理性；对有限元程序进行修改，加入建议模型子程序模块，采用建议模型并对坝体进行有限元应力应变计算，同时与目前应用较广泛的模型(如e - u模型)计算结果比较，初步验证建议模型和合理性。
This paper use the principle of mass concrete temperature raise and down will make concrete inside stress and strain cause change , and mixture ratio of concrete effect temperature stress , and the principle of equilibrium management model of china - pole , and the test curve of temperature in engineering , and the model experiment " anti - pull " together of mass concrete etc , to studied mass concrete anti - crack theory in design , construction and management 本文采用大体积混凝土温度升降引起混凝土内部的应力和应变产生变化及混凝土的配合比对其温度应力的影响原理、链杆平衡管理模型的计算原理、工程温度实测曲线、大体积混凝土“抗?放”结合模型的试验结果等研究了大体积混凝土在配筋设计、施工及施工管理过程中的抗裂措施。
Compared w ith t he c alculated r esults and monitoring data , to verify i f the p resent parameters can accord with the real situation of nanjing . the distribution of surface settlement trough is obtained by one - dimensional wave theory and calculation . the range of surface settlement trough coefficient is retrofitted 通过对比peck法计算值和实测值，验证现有的经验参数是否能很好地满足南京地区的实际情况，通过对实测曲线的拟合和数值计算得到沉降槽半宽度，从而改进了南京地区横向地表沉降槽宽度系数k的取值范围，有助于盾构法在南京地区的推广和应用。
