These diodes can emit light at a variety of wavelengths-but one color they do not produce naturally is white.

些二极可以发出多种波长的光，但它们自然不会产生的一种颜色是白色。

In eighth grade, he built a calculator that included one hundred transistors, two hundred diodes, and two hundred resistors on ten circuit boards.

八年级的时候，他基于二进制理论造出了一台计算器，把 100 晶、200 二极、200 电阻装在了 10 块电路板上。

And that required creating a combination of diodes that together glowed in red, green, and blue.

需要创建一组合的二极， 它们一起发出红色、 绿色和蓝色的光。

Instead of being a cone containing a meristem it will be a cone containing a motor, a light-emitting diode and a battery.

两者都是圆锥结构，不过前者里面有一分生组织，而后者里面是电机，发光二极和电池各一。

Once there, the liquid will be solidified by ultraviolet rays from the diode, extending the cylinder and forcing the cone farther into the soil.

液态塑料到达该位置后马上会因二极发出的紫外线照射凝固，使圆柱增长，促使锥在土壤中更进一步。

An LED is a type of diode or semiconductor device that emits light when electrons flow through layers of crystalline inorganic material.

LED 是一种二极或半导器件，当电子流过结晶无机材料层时会发光。

Much of the light these cells used would, of necessity, come from incandescent bulbs, fluorescent tubes and light-emitting diodes (LEDs) rather than through the window from the sun.

它们所利的光能中的大部分势必来自白炽灯，日光灯和发光二极，而并非透过窗户照射进来的太阳光。

Using diodes and transistors from Radio Shack, and with the help of a music student in his dorm who had perfect pitch, he got it built before Thanksgiving.

他从电器连锁店Radio Shack买来二极和晶，在同宿舍一拥有完美音准感的学生的帮助下，在感恩节之前就完成了制作。

Nakamura for developing the blue light emitting diode, or LED. This ridiculously useful invention is the key to making possible the white LED bulb.

Nakamura 开发了蓝色发光二极或 LED。非常有的发明是使白色 LED 灯泡成为可能的关键。

We use a one way diode essentially for  single direction communication, and so there's no way to access the plant computers  from off site.

我们基本上使单向二极进行单向通信，因此无法从异地访问工厂计算机。

These diodes have been around since the 1950s, but at first we were only able to make ones that emitted either red or green light.

些二极自 1950 年代就已问世，但起初我们能制造发出红光或绿光的二极。

For example, the ENIAC, consisted of more than 17,000 vacuum tubes, 70,000 resistors, 10,000 capacitors, and 7,000 diodes, all of which required 5 million hand-soldered connections.

例如，ENIAC 由 17,000 多真空、70,000 电阻器、10,000 电容器和 7,000 二极组成，所有些都需要 500 万手工焊接连接。

An electronic component that permits the one-way flow of current is called a diode, but what was really needed was a switch to help turn this flow on and off.

任何允许电流单向流动的电子部件都叫做二极，但我们还是需要一开关来开关电路。
