hydrostatic equilibrium

名詞

可算名詞 不可算名詞

(physics) The state in which a solid or liquid body has relaxed into the shape that it would have if it were a calm (equilibrium) liquid. Mathematically, this means a sphere if it is not distorted by another body and is not rotating, but an oblate or scalene ellipsoid if rotating moderately, and piriform if rotating beyond the ellipsoidal limit. When in contact with another object, such as oil drops on or in water, other shapes occur.

日本語の意味

物体（固体または液体）が、外部の力や動的な影響を受けず、内部の圧力や重力が釣り合い、安定した形状に落ち着いている状態。 / 非回転状態では理論上球体となるが、適度な回転がある場合には扁平または斜体楕円体、過度な回転の場合には梨形などの変形が生じる状態。 / 接触している他の物体（例：水中の油滴など）との相互作用によって、さらに異なる形状が現れる場合がある状態。

When a small moon cools and softens, its surface gradually relaxes into hydrostatic equilibrium, taking on a nearly spherical shape unless rotation or tidal forces distort it.

小さな衛星が冷えて柔らかくなると、その表面は次第に静水圧平衡の状態に落ち着き、回転や潮汐力で歪められない限りほぼ球形を取る。
