说明：  一架飞机在海上失事，搜救人员打捞出了该机的黑匣子，技术人员从其中的内存里恢复了一段声音plane.wav，经推断该声音是失事之前最后时刻的数据，设备供应商证实该声音是通过频分复用生成后准备发送出去的，复用的其中一路信号可能含有驾驶员最后发出的指令，现在要求对该声音进行分析，并恢复可能存在的指令，同时能够利用平台实时播放提取的信号。 内含matlab和CCS两份代码(A plane crashed at sea, search and rescue personnel salvaged the black box of the plane, the technician recovered a piece of sound plane.wav from its memory, and it was inferred that the sound was data at the last moment before the crash, and the equipment supplier confirmed the sound It is prepared to be sent out after being generated by frequency division multiplexing. One of the multiplexed signals may contain the last command issued by the driver. Now it is required to analyze the sound and restore the possible instructions. At the same time, the extracted signals can be played in real time using the platform.)

常见的外部管理系统，文章写了一些常见的外部排序的算法及实现(Common external management system, the article written some of the common external sorting algorithm and implementation)

基于matlab的源程序，用于画非线性微分方程杜芬方程的相图(Source program based on matlab, used to draw the phase diagrams of nonlinear differential equation- duffing equation)

4. 实现函数max（），来输出树中的最大值。 template <typename T> tnode<T> *max(tnode<T> *t) 请参考第三题中计算树的深度算法，编写程序，调用max（）显示整数树中的最大值。(4. To achieve function max (), to maximum output in the tree. template <typename T> tnode <T>* Max (tnode <T>* T) refer to the third question in the calculation of the depth of the tree algorithm, programming, call max () shows the maximum integer tree.)
