Instable
“Instable” 是一个形容词,意为“不稳定的”。它描述的事物容易发生改变、倒塌或失去平衡。虽然在现代日常英语中 “unstable” 更为常用,但在某些科学和专业领域,“instable” 仍被使用。
- “The chemical compound is highly instable and must be stored carefully.” (这种化合物非常不稳定,必须小心储存。)
- “The political situation in the region remained instable for months.” (该地区的政治局势几个月来一直不稳定。)
- “The patient’s condition was described as instable after the surgery.” (手术后,病人的情况被描述为不稳定。)
源于中世纪英语,来自古法语 instable,最终源于拉丁语 instabilis,由 in-(不)+ stabilis(稳定的,源自 stare “站立”)组成。
- 前缀: in- (表示“不”)
- 词根: stable (稳定的)
在物理学和化学中,“instable” 描述一个平衡状态极易受到扰动而破坏。在心理学中,它也用来形容情绪波动剧烈的人。
- 固定搭配: “instable equilibrium” (不稳定平衡), “instable condition” (不稳定状态)。
- 相关形式: instability (名词), instably (副词)。
in (不) + stable (稳定的)。联想一个站(stand)不稳的桌子。
