用于心音信号包络的分割，信号处理的技术领域，具体的说，涉及一种心音信号周期的检测与心音的状态分割方法。其中，心音的状态分割方法是在时间维度上判断某时刻某段时长内出现的心音状态的类别。(Envelope Segmentation of Heart Sound Signals)

三角分解法亦称因子分解法，由消元法演变而来的解线性方程组的一类方法。设方程组的矩阵形式为Ax=b，三角分解法就是将系数矩阵A分解为一个下三角矩阵L和一个上三角矩阵U之积：A=LU，然后依次解两个三角形方程组Ly=b和Ux=y，而得到原方程组的解，例如，杜利特尔分解法、乔莱斯基分解法等就是三角分解法(The triangular decomposition method, also called factor decomposition method, is a kind of method of solving the linear equation group by the evolution of the elimination method. A form of matrix equations Ax=b, triangular decomposition is the coefficient matrix A is decomposed into a lower triangular matrix and an upper triangular matrix L U product: A=LU, followed by the solution of two triangular equations Ly=b and Ux=y, and get the original equations, for example, Doolittle method, Jo Lessky decomposition is a triangular decomposition method)

说明：  一种快速的抗噪声模糊C均值图像分割算法 图像分割就是把图像分成若干个特定的、具有独特性质的区域并提出。该算法结合像素灰度值相似度和隶属度构造了一个新的空间函数。该空间函数用于更新成员关系，而成员关系又用于迭代地获取聚类中心。所提出的算法可以在较少的迭代次数下获得理想的分割结果，有效地降低了噪声的影响。(A fast anti noise Fuzzy C-Means Image Segmentation AlgorithmImage segmentation is to divide the image into several specific, unique areas and propose. In this algorithm, a new spatial function is constructed by combining the similarity and membership of pixel gray value. The spatial function is used to update the membership, and the membership is used to obtain the cluster center iteratively. The proposed algorithm can get ideal segmentation results with less iterations and effectively reduce the impact of noise.)

C51的一些误区和注意事项（ZT） 1)C忌讳绝对定位。 常看见初学者要求使用_at_,这是一种谬误，把C当作ASM看待了。在C中变量 的定位是编译器的事情，初学者只要定义变量和变量的作 用域，编译器就把一个固定地址给这个 变量。怎么取得这个变量的地址？要用指针。比如unsigned char data x 后，x的地址就是... -C51 some errors and attention to the business (ZT) 1) C taboo absolute positioning. See beginners often require the use of _at_, this is a fallacy, ASM C as a treat. C variables in the positioning of the compiler things, as long as the definition of beginners variable and the variable scope, Compiler put a fixed address to this variable. How the variables made the address? Use indicators. Unsigned char data such as x, x is the address ...
