Labile
“Labile” 是一个科学和医学术语,用来描述那些容易发生变化、不稳定或持续改变的事物。在化学中,它指容易分解的化合物;在心理学中,它指情绪波动非常剧烈。
- “The patient’s emotional state was extremely labile, switching from laughter to tears in seconds.” (患者的情绪状态极其不稳定,几秒钟内就能从大笑转为流泪。)
- “These compounds are highly labile and must be kept at a very low temperature.” (这些化合物极不稳定,必须保存在极低的温度下。)
- “The political situation in the region remains labile, with frequent changes in leadership.” (该地区的政局依然动荡,领导层更迭频繁。)
源自拉丁语 “labilis”,意为“滑动的、容易滑下的”。
- 词根:
lab-(滑动,如 lapse) - 后缀:
-ile(形容词后缀,表示倾向或能力)
在精神病学中,“emotional lability”(情绪不稳)是评估患者心理状态的重要指标。在药理学和生化研究中,如何稳定那些 “labile proteins”(易变蛋白质)是一个重大的技术挑战。
- 相关词汇: lability (名词, 不稳定性)
联想 “Label”(标签)。如果你在一个容易坏的东西上贴上一个 “Labile” 的标签,你就知道它很容易“变坏”或“变化”。或者联想其词根 lab- 就像 “lapse”(滑落,流逝)。
“In the laboratory, Dr. Chen was working with a very labile substance that could solve the energy crisis. However, the smallest change in room temperature would cause the substance to break down. He spent weeks perfecting a stable container, knowing that the potential of this labile material was too great to let it slip away through instability.” (在实验室里,陈博士正在研究一种极不稳定的物质,这种物质可能会解决能源危机。然而,室温哪怕发生极其微小的变化,都会导致该物质分解。他花了几周时间完善一个稳定的容器,因为他知道这种易变材料的潜力太大,不能因为不稳定性而任其流失。)
