| 单词 | 中电压 |
| 释义 | 〔power〕The product of the effective values of the voltage and current with the cosine of the phase angle between current and voltage in an alternating-current circuit.伏特量：交流电路中电压与电流的有效值以及电流与电压之间相位角的余弦之乘积〔glitch〕Although in retrospectglitch seems to be a word that people would always have found useful, it is first recorded in English in 1962in the writing of John Glenn:"Another term we adopted to describe some of our problems was ‘glitch.’”Glenn then gives the technical sense of the word the astronauts had adopted:"Literally, a glitch is a spike or change in voltage in an electrical current.”In this very passage we see how the word moved from its narrow, technical electronic sense to a more general sense, even if the astronauts were not necessarily the first to extend the meaning ofglitch. Since then the word has passed beyond technical useand now covers a wide variety of malfunctions and mishaps.回溯历史，尽管glitch 似乎是一个向来有用的单词， 但是直到1962年它才首次在英语中有记录，在约翰·格林著作中：“我们所采用的另一个用来描述我们的问题的词汇是‘glitch’”。格林给这个词下了为宇航员所采用的专业定义， “严格来说，glitch是指电流中电压受阻或变化。”。在这里，即使宇航员不一定是第一个引申了glitch 的含义，可是我们看到这个词是如何从它狭义的电子技术上的意义发展到更普遍的意义。 此后这个词超出了技术上的使用范围，现在可指多种功能故障和灾祸 |
