In this tube, we have an ionization chamber.

在这个管子里，我们有一个电。

Second, in our explanation we simplified the circuitry of the smoke detector's ionization chamber.

其次，在我们解释中，我们简化了烟雾探测器电电路。

However, in this contraption, called an ionization chamber, we want to use alpha decay to help us detect smoke.

然而， 在这个叫做电装置中，我们想利用阿尔法衰变来帮助我们检测烟雾。

In other words, they produce the greatest number of ions and a steady flow of current in the ionization chamber when no smoke is present.

换句话说，当没有烟雾时，它们会在电内产生最多子和稳定电流。

In reality, the top middle cylinder is also an ionization chamber, and the circuitry senses the voltage of the middle disk and compares the ionizing activity in the top chamber to the reference ionizing activity in the bottom chamber.

实际上， 中间上方圆柱体也是一个电，电路会感应中间盘电压， 并将上部电中电活性与底部电中参考电活性进行比较。
