说明：  利用二阶循环统计量去除同频带干扰的影响，同时，当信号为相干信号时，也可以去相关，得到较好的结果，(Using second-order cyclic statistics to remove the influence of interference in the same frequency band)

求解雷诺方程有有限元法、有限差分法、有限体积法，本程序就是采用有限体积法对雷诺方程进行求解。(Solving Reynolds equation has finite element method, finite difference method, finite volume method, the program is the use of finite volume method to solve the Reynolds equation.)

control souce code with LQR

这是2011年中国等离子暑期学校关于磁流体力学（MHD）的讲义，授课的老师是北京大学的王晓刚教授，非常经典！(This is the 2011 China Summer School on magnetic plasma hydrodynamics (MHD) lectures, taught at Peking University Professor Wang Xiaogang teacher, very classic!)

有直接法,间接法,Bartlett法,Welch法(有????? ????? Bartlett ? Welch )

基于经典的增广拉格朗日乘子法, 对求解一类带有特定结构（主要是针对凸规划）的非光滑等式约束优化问题, 我们提出、分析并测试了一个新算法. 在极小化增广拉格朗日函数的每一步迭代中, 该算法有效结合了带有非单调线性搜索的交替方向技术, 我们建立了算法的收敛性, 并用它来求解在带有全变差正则化的图像恢复问题.(Based on the classic augmented Lagrangian multiplier method, we propose, analyze and test an algorithm for solving a class of equality-constrained nonsmooth optimization problems (chiefly but not necessarily convex programs) with a particular structure. The algorithm effectively combines an alternating direction technique with a nonmonotone line search to minimize the augmented Lagrangian function at each iteration. We establish convergence for this algorithm, and apply it to solving problems in image reconstruction with total variation regularization.)

泽尼克拟合算法，包括直角坐标系拟合和极坐标系的拟合，成熟代码，还请放心！(Zernike fitting algorithm, including fitting, fitting and polar coordinates Cartesian coordinates of the mature code, please rest assured!)

自制的计算器，可实现加减运算，清除，后退等功能(Homemade calculator, can realize the addition and subtraction, clear, back, etc)

这是考虑了高程的面积计算公式，VB编的程序，运行即可(This is the old area of the elevation calculation formula, the program can be run VB series)
