晶体管

Until this time, nearly all transistors had utilized germanium because it was easier to prepare in pure form.

到目前为止，由于较容易取得纯净的锗元素，几乎所有的晶体管皆是利用锗来制成的。

In fact , the transistor consists of only a single piece of germanium or silicon with wires connected to it.

事实上，晶体管只是由一个锗片或硅片构成的，导线都接在其上面。

However, germanium transistors are relatively expensive, so use them only in applications requiring low-input-voltage operation.

然而，锗晶体管价格相对高些，所以只在需要低输入电压的应用中使用。

Gold 's is mainly used in gold reserve , decoration , coins and currencies . Gold can be also used as touch point of down lead and suppresser in diode and transistor .

金的主要用途：金主要做黄金储备，装饰口及货币，此外在二极管和晶体管中可作引线的触点和抑制器，还可作能量反射器。

Detailed introductions were made to the application in frequency converter for unit series multi-electrical level, power bus, micro-computer control and artificial intelligence, total digitalized optical fiber control and power unit standard modulization, insulated grid bipolar transistor drive circuit intelligentize etc.

介绍了变频器的市场情况以及变频技术的现状，详细介绍了单元串联多电平、功率母线、微机控制和人工智能、全数字化光纤控制以及功率单元标准模块化、绝缘栅双极晶体管IGBT驱动电路智能化等技术在变频器上的应用。

The innovative processor is based on hafnium, a metal that is used in transistor production as well as in nuclear plant control rods.

创新的处理器是基於铪，金属是用来在晶体管的生产，以及在核电厂的控制杆。

The company said the transistors and its next generation of processors will be made using hafnium, a kind of metal instead of silicon.

该公司说，它的晶体管和下一代处理器将用"合"作为原料。

I can say with high confidence that there is no other SS headphone amp of this caliber.

我很大信心说这是没有其他晶体管耳机放大器可以达到。

Jan Hendrik Schon and colleagues at Bell Laboratories created diodes and transistors on the same tiny scale.

贝尔实验室的 Janhendrik Schon 和同事们也制造成同样微小的二极管和晶体管。
