我用CNKI查了下，感觉如果是气相组件翻译成有源器件比较好，和楼主字典查到的近似吧！这个是不是涉及到电器一些知识，只是检测器的一个组件而已。 比如下面的例句： These two kinds of filter circuit can be implemented, respectively, by using an active element, without changing circuit configuration and not in need of adjusting RC ratios, functions of lowpass, highpass, and bandpass can be realized simultaneously in three different branches. 这2种电路分别只用了1个有源器件,不用改变电路结构,也不必调整RC的比值,同时可在3条支路中实现带通、高通和低通滤波功能。
In this paper, a chaotic oscillator circuit using a frequency dependent negative resistor (FDNR) is proposed. The circuit relies on a grounded FDNR as the active element and employs a general purpose signal diode to provide the necessary non-linearity. 提出了用频变负电阻(FDNR)实现混沌振荡器的新电路,该电路结构简单,易于集成,仅用一个接地的频变负电阻作为有源器件,用二极管提供必要的非线性。
