i do not know why

from slave

Read_Master_Log_Pos: 26060892
Exec_Master_Log_Pos: 24607963

change operation for master

| Com_insert | 115368 |
| Com_delete | 59314 |
| Com_replace | 0 |
| Com_replace_select | 0 |
| Uptime | 329719 |

and for slave

| Com_insert | 79462 |
| Com_delete | 94723 |
| Com_replace | 39388 |
| Com_replace_select | 115399 |
| Uptime | 238918 |

slave have one table with several triggers do replace operation
so, as u see Com_replace is very high
i do not know if the triggers will cause the problem,because i have modified the trigger last week ,which execute time is 8 min ,so i rewrite the trigger ,now it run very faster
