Ticker 是一个名词,主要有以下含义:
最常见的用法是指股票行情显示器或股票代码(ticker symbol)。
/ˈtɪkər/
The stock ticker showed that prices were rising steadily throughout the morning.
股票行情显示器表明,整个上午股价都在稳步上涨。
After the heart surgery, the doctor assured him that his old ticker was working better than ever, and he could return to his normal routine within a few weeks.
心脏手术后,医生向他保证,他的"老心脏"比以往运转得更好,几周内就能恢复正常生活。
Ticker 源自动词 tick(发出滴答声),加上表示施动者的后缀 -er。19世纪时,最早的股票行情自动收报机(ticker tape machine)在打印股价信息时会发出"滴答滴答"的声音,因此被称为 ticker。后来这个词也被口语借用来指心脏,因为心跳的节奏也像滴答声一样规律。Tick 本身可能源自中古英语,模仿轻敲的声音,属于拟声词。
