metacenter

• 船舶工程术语，指船舶正浮或倾斜时通过浮心的垂线与通过重心的垂线的交点；该点到重心的距离可衡量船舶的稳性。

A technical term in naval architecture referring to the point of intersection between the vertical lines through the center of buoyancy of a ship in equilibrium and when inclined; its distance above the center of gravity indicates the ship's stability.

1. Stability point in naval architectureC2formaltechnical

   The point of intersection between two vertical lines: one through the center of buoyancy of a ship's hull in equilibrium, and the other through the center of buoyancy when the ship is tilted. The height of this intersection above the center of gravity indicates the vessel's stability.

   船舶稳性中的稳心

   • The naval architect calculated the metacenter to ensure the ship's stability in rough seas.
   • A higher metacenter generally indicates a more stable vessel.
   • The distance between the center of gravity and the metacenter is a critical factor in ship design.
