In the '60s and '70s, cathode ray tubes used phosphorous illuminated by electrons to display text and info.

在上世纪 60 和 70 ，极射线管会用电子使磷发光，以显示文字和信息。

And so there's a little cathode ray tube.

所以有一个小型极射线管。

Now this makes a certain amount of sense if you don't happen to have access to electron microscopes or cathode-ray tubes or the work of generations of previous scientists.

现在，如果您碰巧无法使用电子显微镜或极射线管或前几科学家的工作，那么在一定程度上有道理的。

INTRO A lot of different display technologies have been created over the decades, but the most influential, and also the earliest, were Cathode Ray Tubes, or CRTs.

简介：几十来，出现了许多不同的显示技术，最有影响力且也最早出现的极射线管，即CRTs。

To protect people from this radiation, engineers mixed lead into the glass ray tubes— but this batch of GE televisions was produced with faulty tubes.

为了保护人们免受种辐射的危害，工程师们在玻璃极射线管中混入了——一批通用电气公司的电视机使用了有缺陷的极射线管。

The day my parents upgraded to a modern 29-inch Panasonic cathode ray tube TV was perhaps one of the happiest days of my childhood.

我父母升级到一台现的29英寸松下极射线管电视机的那一天，可能我童中最幸福的一天。

I mean it's like a Star Trek thing, right? You're using a light pen to write on a cathode ray tube.

我的意思就像星际迷航的东西，对吧？您正在使用光笔在极射线管上书写。

At a Canadian recycling depot, workers taking apart old TVs, expect to find capacitors, resistors, cathode ray tubes.

在加拿大的一家回收站， 工人们拆开旧电视机，希望能找到电容器、电阻器和极射线管。

Like most other old, boxy TVs, the GE ones used cathode ray tubes, or CRTs, to generate a picture.

像其他大多数老式方形电视一样，通用电气公司的电视使用极射线管（或简称CRT）来生成图像。

To do this, without resorting to memory-gobbling pixels, computer scientists used the vector mode available on CRTs.

为了实现一点，计算机科学家没有使用耗费内存的像素，而利用了极射线管上的矢量模式。
