说明：  在矩形方框中随机生成半径不同的圆，用于模拟多孔介质(Randomly generate circles with different radii in rectangular box to simulate porous media)

说明：  1. 硬件接线 （1）调试串口(UART_Debug)使用UART2，在“printf.h”文件中宏定义， 对应引脚为TX-PTD7，RX-PTD6 （在“uart.h文件中宏定义）。 （2）灯0~3（LIGHT_0~LIGHT_3）对应的引脚是PTC0~PTC3，高电平点亮（由硬件接法决定） （3）SPI0_CLK对应的引脚是PTE0， SPI0_MOSI对应的引脚是PTE1， SPI0_MISO对应的引脚是PTE2，SPI0_PCS对应的引脚是PTE3， SPI1_CLK对应的引脚是PTG4， SPI1_MOSI对应的引脚是PTG5， SPI1_MISO对应的引脚是PTG6，SPI1_PCS对应的引脚是PTG7。 （4）SPI0作为master,SPI1作为slave，SPI1接收SPI0发送的数据并产生中断。 用导线将PTE0与PTG4对接，将PTE1与PTG5对接，将PTE2与PTG6对接，将PTE3与PTG7对接。(1. Hardware wiring (1) Debugging Serial Port (UART_Debug) uses UART2, macro-defined in "printf.h" file, corresponding pins are TX-PTD7, RX-PTD6. (macro definition in the uart.h file). (2) The pins corresponding to the lamp 0~3 (LIGHT_0~LIGHT_3) are PTC0~PTC3, and the high-level lighting is determined by the hardware connection. (3) The pin corresponding to SPI0_CLK is PTE0, and the pin corresponding to SPI0_MOSI is PTE1. The pin corresponding to SPI0_MISO is PTE2, and the pin corresponding to SPI0_PCS is PTE3. The pin corresponding to SPI1_CLK is PTG4, and the pin corresponding to SPI1_MOSI is PTG5. The pin corresponding to SPI1_MISO is PTG6, and the pin corresponding to SPI1_PCS is PTG7. (4) SPI0 acts as master and SPI1 acts as slave. SPI1 receives data sent by SPI0 and generates interruption. PTE0 and PTG4 are docked by wire, PTE1 and PTG5 are docked, PTE2 and PTG6 are docked, PTE3 and PTG7 are docked.)

Flash小球特效 跟随鼠标旋转，可把本效果应用于flash Loading剪辑中，鼠标移动的超快，小球旋转的越快，整体上是随着鼠标移动的，可以看作是鼠标跟随特效吧。

说明：  simulink逆变器并网仿真。（1）分别建立新能源发电并网系统的数学模型，并在Simulink上进行仿真验证。? （2）探讨控制策略，详细地研究双闭环控制的设计方法。? （3）计算、设置逆变器主电路及控制电路各器件的参数值，在Simulink上进行仿真调试，使得仿真结果符合设计的指标，分析仿真结果。(Simulink inverter grid connection simulation)

说明：  EMR的开发包,开发医疗软件的时候可以用来学习参考(EMR development kit, when developing medical software can be used for learning reference)

实现了省份和城市的二级级联效果，简单易懂，大家可以参考(It achieves the secondary cascade effect of provinces and cities, which is simple and easy to understand. You can refer to it.)
