A practicable transistor on-off circuit is presented which can measure capacitance and dielectric constant accurately.
介绍一个实用的晶体管开关电路，用它能够较准确地测定电容和介电常量。
The transistor, when fully saturated, could turn a circuit on or off, and then could be used to control an electrical circuit or store information in an electrical circuit.
当该晶体管时完全饱和，能把一个电路打开或关闭，然后可用于控制一个电路的工作，或者将信息存储在一个电路。
The circuit also includes a second subcircuit that causes a second transistor (25) that is coupled to the circuit's output (34) to turn on during a falling transition and then turn off.
该电路还包括第二分支电路，该第二分支电路使得耦合到该电路的输出(34)的第二晶体管(25)在下降跃迁期间导通并接着被断开。
