*3级，**主要*
*定义：*功能存在缺陷，但不影响应用和系统的稳定性
*对应**优先级**：**中*
*具体可分为：*
1.内存泄露（长时间不用的对象需要被回收，不被回收占内存）
2.功能实现逻辑覆盖不全面
3.非必现，但复现概率超过50%的闪退/崩溃和安全模式

*4级，**一般*
*定义：*对应用熟悉度高才能感知到的问题，对应用基本功能实现无影响
*对应**优先级**：**中*
*具体可分为：*
1.轻微数值计算错误
2.功能实现有误，与产品文档不完全贴切
3.用户简单操作，即可明显感知的UI问题

*5级，**较小*
*定义：*界面，性能缺陷
*对应**优先级**：**低*
*具体可分为：*
1.操作界面错误（提示显示规则，刷新规则是否与文档一致）
2.边界条件显示错误
3.提示信息和界面效果展示错误（包括未给出信息、信息提示错误等）
4.复现率低于5%的闪退/崩溃和安全模式
5.插件兼容和性能未优化问题
6.非正常操作导致UI显示异常
