v.动词
evaporate, evanesce, vanish这组词都可表示“从视线消失或不复存在”。其区别是：
vanish指完全地、常常是神秘而骤然地消失,不留任何蛛丝马迹; evanesce强调从视线或头脑里消失的过程; evaporate指犹如水蒸发时那样悄然逝去,也指某人悄悄地,突然地离去或退出。
vanish，disappear，fade，evaporate这些动词均有“消失”之意。
vanish语气强，指完全、往往是神秘而突然的消失，不留任何蛛丝马迹。
disappear普通用词，强调从视线或脑海中消失。这消失可能是暂时的、突然的或永久的，视上下文而定。
fade侧重逐渐消失。
evaporate指像水蒸发时那样悄然逝去，也指某人悄悄地、突然退出或离去。
直接源自中古英语的evaporaten，意为使蒸发，蒸发。
