说明：  一款Bootstrap垂直手风琴折叠菜单。该Bootstrap垂直手风琴折叠菜单使用boostrap网格进行布局(A Bootstrap vertical accordion folding menu. The Bootstrap vertical accordion folding menu is laid out using boostrap grid)

基于最佳维纳滤波器的盲解卷积算法，给定信号为任意类型子波，期望输出可以有五类选择 （类型1：零延迟尖脉冲；类型2：任一延迟尖脉冲； 类型3：时间提前了的输入序列；类型4：零相位子波；类型5：任意期望波形。）(Blind deconvolution algorithm based on Best Wiener Filter (Blind Deconvolution) has five types of desired output (type 1: zero-delay spike; type 2: any delay spike; type 3: time-advanced input sequence; type 4: zero-phase wavelet; type 5: arbitrary desired waveform).)

说明：  wpf list 所有样式控件，去掉边框，修改选择状态，去掉虚线(WPF list all style controls, remove borders, modify selection status, remove dashed lines)

说明：  随机森林matlab工具箱，可以实现分类和回归(Randomforest Tool Box)

lagrange插值 在数值分析中，拉格朗日插值法是以法国十八世纪数学家约瑟夫·拉格朗日命名的一种多项式插值方法。许多实际问题中都用函数来表示某种内在联系或规律，而不少函数都只能通过实验和观测来了解。如对实践中的某个物理量进行观测，在若干个不同的地方得到相应的观测值，拉格朗日插值法可以找到一个多项式，其恰好在各个观测的点取到观测到的值。(interpolation In numerical analysis, the Lagrange interpolation method is a polynomial interpolation method named after the French mathematician Joseph Lagrange in the eighteenth century. In many practical problems, functions are used to express certain internal relations or laws, and many functions can only be understood through experiments and observations. If a physical quantity is observed in practice and the corresponding observations are obtained in several different places, the Lagrange interpolation method can find a polynomial, which just takes the observed values at each observation point.)

用于计算潜在蒸发量，是一个很好的程序。推荐大家用该数据计算流域的潜在蒸发量。(It is a good program to calculate the potential evaporation. It is recommended to use this data to calculate the potential evapotranspiration of the basin.)
