渗流计算，渗流浸润线的计算，溢出点高程的确定(seepage computation)

Abaqus UMAT code 适用于平面应变，轴对称弹塑性本构关系，也适用于大应变情况，使用显示积分算法。(Abaqus UMAT code applies to plane strain, axisymmetric elastoplastic constitutive relation, also applicable to large strain, using the integration algorithm.)

用SVD奇异值分解法和阻尼最小二乘算法解决地球物理反问题，程序比较简单易懂(Using SVD, singular value decomposition method and damped least-squares algorithm to solve geophysical inverse problem, the procedure is relatively simple to understand)

利用for语言精确模拟混凝土的全过程弹性本构(Accurate simulation of the whole process of elastic constitutive of concrete by for language)

说明：  通过面积加权在abaqus程序中提取温度作用数据，计算极值(The temperature action data was extracted by area weighting in abAQUs program and the extreme value was calculated)

说明：  一般的最小二乘通常是一次拿到全部的数据， 对所有数据进行统一优化计算得到模型系数。递推最小二乘是以一种递推的方式计算最小二乘，每次使用最新的测量值，来不断更新模型系数。(General least squares usually get all the data at one time, and perform unified optimization calculations on all the data to get the model coefficients. Recursive least squares is to calculate the least squares in a recursive way, each time the latest measured value is used to continuously update the model coefficients.)

说明：  多维随机数的生成方法，一维随机数生成方法，高维随机数的生成方法(Generation methods of multidimensional random number, one-dimensional random number and high-dimensional random number)
