正确表达There has been a ratcheting up of violence in the region.
这里需要动词 ratchet up 的名词化形式 ratcheting up(逐步加剧);ratchet 作名词时指棘轮,不能表示“逐步上升”,把动词当名词用是词性误用。
取“仅向一个方向逐步移动”之义:ratchet 指朝单一方向逐步移动,fluctuate 则指方向不定、上下波动。
取“使(某物)递增或递减”之义:ratchet 强调逐步改变(增或减),maintain 则强调保持原有水平、不使其改变。
escalate 只能表示逐步升级或加剧,方向是向上的;ratchet 可表示逐步增加或减少,并强调像棘轮一样受控地单向调整。
increment 通常只指按固定小步幅增加数量,没有 ratchet 那种“可增可减、单向锁定”的机械调节含义。
decrement 只表示数值逐步减少,方向向下;ratchet 可表示增加或减少,且常含“单向锁定、受控调节”的机械意象。
