+# 传感器及检测技术 - 实验课件系统
+
+这是一个基于 React 的传感器及检测技术实验课件交互式平台。
+
+## 技术栈
+
+- **框架**: React 19 + Vite 7
+- **样式**: Tailwind CSS 4
+- **路由**: React Router Dom 7
+- **拖拽**: @dnd-kit
+- **HTTP 客户端**: Axios
+- **图标**: Lucide React
+- **包管理器**: pnpm
+
+## 开发环境要求
+
+- Node.js 18+
+- pnpm 10+
+
+## 安装依赖
+
+```bash
+pnpm install
+```
+
+## 开发命令
+
+```bash
+# 启动开发服务器
+pnpm dev
+
+# 构建生产版本
+pnpm build
+
+# 预览生产构建
+pnpm preview
+
+# 代码检查
+pnpm lint
+```
+
+## 项目特性
+
+- 支持拖拽交互的实验课件展示
+- 响应式设计，适配多种设备
+- 模块化组件架构
+- 现代化的 UI 设计
+
