| Abstract: | The study on the periodical vent of the hole shows that the vent period becomes larger with passing time,and becomes smaller with the increasing diameter of hole.The periodical vent couldn't occur if one liquid isn't compatible with another.The above phenomena are analyzed. |
| |
| Keywords: | hole periodical vent circulation steady flow turbulent flow |
