Open the ship lock, and when the gravity acceleration is not equal to 0 and its value is equal to the values of all parts in the communication device, inject the liquid with the same uniform density into the communication device. When the liquid is stationary relative to the communication equipment, the liquid level in each container of the communication equipment remains horizontal, the gate is completely opened, and the ship enters or leaves.
