说明：  一种全新的python 用于疲劳强度迟滞回线的脚本分析(a pthon is created to analysis fatigue behavior)

说明：  主成分分析方法PCA与灰度共生矩阵GLCM 主成分分析方法是一种使用最广泛的数据降维算法。 灰度共生矩阵是一种描述图像局部区域或整体区域的某像素与相邻像素或一定距离内的像素的灰度关系的矩阵。即求灰度图像中某种形状的像素对，在全图中出现的次数。(PCA and Gray Co-occurrence Matrix GLCM The principal component analysis method is one of the most widely used data reduction algorithms. The gray level co-occurrence matrix is a matrix describing the gray level relationship between a pixel in a local area or an entire area of an image and neighboring pixels or pixels within a certain distance. That is to find the number of times a pixel pair of a certain shape appears in the whole image in a grayscale image.)

本程序是在一个房间里猫捉老鼠的游戏。通过键盘上的上、下、左、右方向键控制一只猫，十只老鼠在窗口中自由活动，可随时改变行走方向，遇窗口边界则改变方向。猫碰到老鼠后就吃掉它（该鼠不再显示）。若猫吃掉所有老鼠，游戏结束并显示游戏所剩时间；若时间用完，猫没有吃掉所有老鼠， 游戏结束并显示所剩老鼠数目。-This program is in a room where a cat-and-mouse game. Through the keyboard up, down, left and right arrow keys to control a cat, 10 mice in the window to freely travel at any time to change the direction of the window border, however, to change the direction of the event. Encountered after the cat mouse eat it (the mouse is no longer displayed). If the cats eat all the rats, the game is over and displays the time remaining for the game if time runs out, the cat did not eat all the rats, the game is over and displays the number of the remaining mice.

说明：  能够调节频率，并且能够产生四种波形的AD(Able to adjust the frequency and waveform to produce four AD)

应用背景设计并制作了一个用于电池储能装置的双向 DC-DC 变换器，实现电池的充放电功能，功能可由 按键设定，亦可自动转换。 关键技术 作品设计了一个电池储能的双向DC-DC变换器。该系统以STM32F103ZET6单片机作为控制核心，其输出PWM信号通过6N137光耦隔离，IR2110驱动功率MOS，采用LM358做电压跟随，INA282采集电流，通过ADS1115采集到单片机以实现负反馈控制。用TFT-LCD进行显示操作界面及相应参数，加上PID算法，能够实现软件上的过冲保护，及稳定充电电流。GUI界面的应用，使得人机交互更为友好、整体操作更为智能、简洁。通过测试，该系统能够实现在1-2A范围内以0.01A的步进值进行调整，其精度高于5%。充电模式效率达95%，放电效率达96%以上。
