3.動詞及物C1
釋義

人工誘發

以人為方式啟動生理或化學過程

to deliberately start a biological, medical, or chemical process through active human intervention, using artificial methods rather than allowing natural onset — the key contrast with sense 2 is that the cause here is always a person or a procedure, not an impersonal force; for example, a doctor inducing labour or an anaesthetist inducing unconsciousness before surgery.

例句

The doctors decided to induce labour because Nadia's pregnancy had passed the due date.

Nadia 的懷孕已經過了預產期，醫生決定催生。

induce labour — fixed medical collocation

4.動詞及物C2
釋義

推論；感應

由具體事例推導通則，或經電磁感應產生

to derive a general principle or rule from specific examples (reasoning), or to create an electric current or magnetic effect in an object without direct contact (physics) — for example, inducing a mathematical formula from repeated test data, or a moving magnet inducing voltage in a nearby coil.

例句

From hundreds of test results, the researchers induced a general law about gas behaviour.

從數百筆測試結果中，研究人員推導出關於氣體行為的普遍定律。

induce + general law/principle (scientific reasoning)

A moving magnetic field induces an electric current in a nearby copper wire.

induce + electric current (physical induction)

同義詞
  • infer

    reach a conclusion from evidence; more everyday term

  • deduce

    reason from general principles to specific conclusions

  • extrapolate

    extend known data to unknown cases; formal

文法句型

induce + noun (general principle / current)

用法筆記

Used in scientific, mathematical, and philosophical contexts. The electromagnetic sense (inducing current/voltage) is a distinct technical domain. This sense is rare in everyday language; 'infer' or 'deduce' are more common alternatives for the reasoning meaning.

常見錯誤

❌I induced that it would rain from the dark clouds.
✅I inferred that it would rain from the dark clouds.
💡'Induce' in this sense means deriving a general rule from specific examples; 'infer' means reaching a specific conclusion from evidence.
