【实例简介】辛苦整理的统计年鉴，1982-2019年，都可以复制。可直接批量复制、粘贴与操作，避免了每次找不同表格的数据都需要打开一个excel的繁琐，希望能够帮助到大家。对写论文有很大帮助。

本资源包括，基于SEIR模型的新冠肺炎疫情分析matlab代码和最新的国内疫情数据集。代码已详细备注

STM32控制电机，通过STM32定时器产生PWM波，其中包括串口的配置，定时器的配置，系统时钟的配置，可以实现电机的正反转以及相应LED灯的控制

用python写的跑酷类小游戏，适合新手参考，现在只实现了吃金币和障碍物碰撞功能，相对比较简单，可以自己拓展。

用Delphi2010编码实现。在开发中遇到了几个问题，现写出来供需要的朋友参考。1. SSL问题，用的是indyhttp控件，使用SSL时需要添加 IdSSLIOHandlerSocketOpenSSL1 组件然后 idhttp的iohandler 属性指向 IdSSLIOHandlerSocketOpenSSL1。然后 SSLoptions 的method属性改为 sslvSSLv23然后再放置两个SSL用到的 DLL 文件，可从这里下载Delphi 2010兼容的dll文件 http://pan.baidu.com/s/1mh6Lu6O2.图片编码问题，刚开始试用
