同義詞
  • one-way

    A direct synonym, but less frequently used than both 'one-way' and 'unidirectional'.

  • linear

    Used in science to describe a cause-and-effect chain. Broader meaning — 'linear' does not always imply a single physical direction.

反義詞

    Moving or operating in two opposite directions. Common in computing (bidirectional data transfer) and communications.

文法句型

unidirectional + noun (flow / traffic / signal / movement)

用法筆記

Frequently used before nouns in technical or scientific contexts (flow, traffic, signal, transmission, movement). Not common in everyday conversation about general topics.

常見錯誤
