Areas 1-4 are first all draw white. Areas 3&4 are then drawn grey. Areas 2&4 are then drawn grey. Areas 2&3 are thus double drawn while area 4 is triple drawn.

在WIN32中，每一个线程都对应着一个消息队列。由于一个线程可以产生数个窗口，所以并不是每个窗 口都对应着一个消息队列。下列几句话应该作为"定理"被记住： "定理" 一 所有产生给某个窗口的消息，都先由创建这个窗口的线程处理； "定理" 二 Windows屏幕上的每一个控件都是一个窗口，有对应的窗口函数。消息的发送通常有两种方式，一是SendMessage，一是PostMessage(In WIN32, each thread corresponds to a message queue. Since a thread can have several windows, so not every window corresponds to a message queue. The following words should be a " theorem" to be remembered: " Theorem" all produce a message to a window, all threads initially create the window treatment " Theorem" Two Windows on the screen is a control for each window, there is the corresponding window function. Messages sent are usually two ways, first, SendMessage, PostMessage first)

说明：  该软件的处理类似于短时傅立叶变换（STFT），但应用了更长、更重叠的分析/合成窗口，使时频处理从根本上对混叠具有鲁棒性。这种差异与非常活跃的时频处理技术有关，例如Dirac或优化的自适应波束形成器。(The software does processing similar to the short-time Fourier transform , but applies the longer and more overlapping analysis/synthesis window to make the time-frequency processing fundamentally robust for aliasing.)

用simulink中s函数实现离散系统传递函数(S function with simulink realization of discrete system transfer function)

基于STM32HAL库的外接串口CH432，针对单片机串口不够用的情况用(The external serial port CH432 based on STM32HAL library is used to solve the problem that the serial port of single chip computer is not enough.)
