这段代码可以优化的地方有：

1. 将重复的代码提取出来，避免重复书写。例如，多次调用 `LCD_DisString` 可以提取出来作为一个函数，减少代码重复。

2. 将一些条件语句的判断条件提取出来，避免重复书写。例如，多次使用 `DBData[i]` 的值进行判断，可以将它提取出来，避免重复书写。

3. 使用 switch 语句来替换多个 if-else 语句，使代码更加清晰。

4. 对于 `sprintf(szVal, "%0.3f" , get_ActionDZInfo_val(UNIT_GAP_RT1064,gapid,DBData[i]))` 这一行代码，可以考虑使用 snprintf 函数来避免缓冲区溢出。
