• balance

  The everyday, general word for a steady, evenly spread state; used casually for physical steadiness or for balancing responsibilities like work and family, and rarely sounds formal or scientific.

• equilibrium 本词

  A more formal or technical word, often for a state where opposing forces exactly cancel out; common in physics, biology, or literary writing, and sounds stiff in casual daily contexts like scheduling.

  更正式或专业的词，常指相反的力量恰好抵消的状态；常见于物理学、生物学或文学性写作，用在日常安排这类语境中会显得生硬。

  The gymnast struggled to keep her equilibrium on the narrow beam.

  那位体操运动员在窄窄的平衡木上很难保持平衡。

Both describe a steady, even state, but with different tone. Balance is the everyday, general word, used casually for physical steadiness or balancing work and family. Equilibrium is more formal or technical, describing forces that exactly cancel out, common in physics or literary writing.

这两个词在“平衡状态”这个意义上很接近，但语气和使用场合不同：balance 是日常通用词，equilibrium 更正式、偏科学或文学色彩，也常暗示两种相反力量的抗衡。
