电子面单打印SDK

这是一个磁盘检测工具，他的功能强大到无法用语言来形容。(This is a disk detection tool, which is powerful enough to be described in words.)

文件中包含了完整的HHT变换的文件，并给出了如何利用EMD分解进行不同频率成分的信号分离，提取不同频率成分信号的信息的例子。(The file contains a complete HHT transform file, and gives an example of how to use EMD decomposition to separate signals with different frequency components and extract the information of signals with different frequency components.)

220个C语言代码实例大全，一共有220个C源码，涉及到游戏、算法、字符等多方面的技术，比如： 　　解救人质游戏只要可以走到下面的小人那里就赢 　　合并两上有序文件 　　数列求和、猜数字游戏 　　图形的广度优先搜寻法 　　斐波那奇=阶数 　　字符的图形输出等。

说明：  雷达LFM信号分析，用Matlab产生chrip信号，并作出其时域波形和幅频特性(Analysis of radar LFM signal, generate chrip signal with Matlab, and make its time domain waveform and amplitude frequency characteristics)

说明：  stm 32 F407内部输出0-3.3V的电压可控的三角波，(Realization of triangle wave by STM 32)

说明：  针对单一的一个酶促反应，可以得到不同的反应物质在盒子空间中的粒子分布状态，对其他化学反应的研究同样适用。(For a single enzymatic reaction, the particle distribution state of different reaction substances in the box space can be obtained, and the study on other chemical reactions is also applicable.)

说明：  MQTT协议 3.1.1中文版 MQTT是一个客户端服务端架构的发布/订阅模式的消息传输协议。它的设计思想是轻巧、开放、简单、规范，因此易于实现。这些特点使得它对很多场景来说都是很好的选择，包括受限的环境如机器与机器的通信（M2M）以及物联网环境（IoT），这些场景要求很小的代码封装或者网络带宽非常昂贵。(MQTT is a messaging protocol in publish/subscribe mode of client server architecture. Its design idea is lightweight, open, simple and standardized, so it is easy to implement. These features make it a good choice for many scenarios, including limited environments such as machine-to-machine communication (M2M) and Internet of Things (IoT), which require very small code encapsulation or very expensive network bandwidth)

说明：  帧间差分法识别运动图像，在matlab 2019b上使用最好，路径调到解压此文件夹。(The detection of moving video returns a pair of coordinates and sizes, which can identify moving objects.)
