MUSIC算法估计性能分析,详细的介绍了MUSIC算法估计性能(It is very useful in array signal process )

整车模型，其中包括电动机，发动机，变速器，差速器，驾驶员模型等等(CAR MODEL including motor,engine,trans,driver etc)

说明：  从最后一个非叶子结点开始从后往前进行调整，保证了根下的所有子树都是最大堆，最后对根进行调整，使整棵二叉树为最大堆，保证了根结点为整棵数的最大值点，完成了建堆的过程，再将根结点跟最后一个结点进行交换，如此反复操作，则堆排序就完成了，其中堆排序的过程采用了满二叉树的概念。(From the final of a non-leaf node after the move began to be adjusted to ensure that the root of all sub-tree are the biggest pile, and finally adjusted to the root, so that the largest heap binary tree整棵to ensure that the root node for整棵the maximum number of points, completed the process of building reactors, and then the last root node with a node to be exchanged, and so repeated the operation, then HEAPSORT completed, of which the process of HEAPSORT a full binary tree concept.)

随着计算机技术的迅速发展和越来越广泛深入地应用于国民经济和社会生活的各个方面，随着 软件系统的规模和复杂性与日俱增，软件的生产成本和软件中存在的缺陷和故障造成的各类损失也 大大增加，甚至会带来灾难性的后果。软件质量问题已成为所有使用软件和开发软件的人关注的焦 点。由于软件是人脑的高度智力化的体现和产品这一特殊性，不同于其他科技和生产领域，因此软件与生俱来就有可能存在着缺陷。(With the rapid development of computer technology and the more extensively used in the national economy and social life in all its aspects, with the growing size and complexity of software systems, software production costs and software defects and faults caused various types of losses also increased significantly, even catastrophic consequences. Software quality has become the focus of all those who use the software and software development concern. Because the software is highly intellectual expression and product of the special nature of the human brain, unlike other areas of technology and production, so the software may be born with a defect exists.)
