用法筆記

Decreased is the regular simple-past and past-participle form of decrease. Use it alone for a finished past event, and after have, has, had, or be when the grammar needs a participle. The meaning still depends on whether the verb is intransitive (prices decreased) or transitive (the company decreased costs).
