I need to translate the HTML content to Chinese while:
1. Keeping all HTML tags and attributes unchanged
2. Not translating code, URLs, file paths, function names, variable names, class names, method names, command line instructions, or error message code parts
3. Only translating visible text content outside tags
4. Keeping the technical accuracy
5. Making the translated text natural in Chinese

Let me go through and translate the visible text content:

- "STM32G474xx HAL User Manual: Operation on ADC hierarchical scope: ADC instance" → "STM32G474xx HAL用户手册：ADC层级作用域操作：ADC实例"
- "Main Page" → "主页"
- "Modules" → "模块"
- "Data Structures" → "数据结构"
- "Files" → "文件"
- "Directories" → "目录"
- "Functions" → "函数"
- "Operation on ADC hierarchical scope: ADC instance" → "ADC层级作用域操作：ADC实例"
- "ADC Exported Functions" → "ADC导出函数"
- "Put ADC instance in deep power down state." → "将ADC实例置于深度断电状态。"
- "Disable ADC deep power down mode." → "禁用ADC深度断电模式。"
- "Get the selected ADC instance deep power down state." → "获取所选ADC实例的深度断电状态。"
- "Enable ADC instance internal voltage regulator." → "启用ADC实例内部电压调节器。"
- "Disable ADC internal voltage regulator." → "禁用ADC内部电压调节器。"
- "Get the selected ADC instance internal voltage regulator state." → "获取所选ADC实例内部电压调节器状态。"


- "Enable the selected ADC instance." → "启用所选ADC实例。"
- "Disable the selected ADC instance." → "禁用所选ADC实例。"
- "Get the selected ADC instance enable state." → "获取所选ADC实例启用状态。"
- "Get the selected ADC instance disable state." → "获取所选ADC实例禁用状态。"
- "Start ADC calibration in the mode single-ended or differential (for devices with differential mode available)." → "启动ADC校准，单端模式或差分模式（适用于支持差分模式的器件）。"
- "Get ADC calibration state." → "获取ADC校准状态。"

I need to handle note sections, parameter and return value descriptions. On this STM32 series, enabling requires the ADC to be disabled with internal voltage regulator activated. A stabilization delay is needed after enable. The ADRDY flag indicates when the ADC is ready. Disabling requires no active conversions on regular or injected groups. Deep power down mode causes calibration data loss, so recalibration or stored factors must be restored. Voltage regulator stabilization also needs a delay before calibration or enable operations. "Enable/Disable the selected ADC instance" - 启用/禁用所选ADC实例
11. "Get the selected ADC instance enable state" - 获取所选ADC实例启用状态
12. "Get the selected ADC instance disable state" - 获取所选ADC实例禁用状态
13. "Start ADC calibration in the mode single-ended or differential (for devices with differential mode available)" - 启动ADC校准，单端或差分模式（适用于支持差分模式的器件）
14. "Get ADC calibration state" - 获取ADC校准状态
