How to use 测定
测定 is a formal, technical verb used in science, medicine, engineering and surveying. Its object is usually a measurable quantity such as 含量 (content), 浓度 (concentration) or 年代 (age). Example: 科学家测定了这块化石的年代。(Kēxuéjiā cèdìngle zhè kuài huàshí de niándài.) Scientists determined the age of this fossil.
测 (cè) means to measure, and 定 (dìng) means to fix or settle. You measure something until the answer is settled: 测定 is to determine a value by measuring.
Common mistake: Learners often use 测定 where 决定 (juédìng) or 确定 (quèdìng) is needed. 测定 only means finding a value through measurement, so 我测定明天去北京 is wrong. Say 我决定明天去北京.
