The efficient power output of interval oscillator can be held almost constant when the output power of the voltage source is varied in a given range, and its oscillatory frequency lies in the range between low and medium frequency when the tube is in its regular lighting scope.
对间歇振荡器的有功功率输出特性和频率输出特性研究发现：在一定范围内，改变电源的输出功率，间歇振荡器的有功功率的输出，可大致保持不变；在光管正常发光的范围内，它的振荡频率位于中低频之间。
