“突减的”可以用英语表达为 “suddenly decreasing” 或 “abruptly declining” ,具体使用哪个取决于语境:
“suddenly decreasing”:强调变化发生的突然性,“decreasing”表示数量、程度等在减少。例如:“There was a suddenly decreasing trend in sales last month.(上个月销售额出现了突减的趋势。)”
“abruptly declining”: “abruptly”同样有突然的意思,“declining”更侧重于描述一种下降、衰退的状态。例如:“The stock price showed an abruptly declining pattern yesterday.(昨天股价呈现突减态势。) ”
