| 摘 要： | 从电阻产生的物理机制即电子与晶格的碰撞出发，对耦合部分有电阻时的电感耦合电路进行了量子化，给出了分回路及以往未加注意的耦合部分的量子涨落，同时计入了温度效应，结果表明，量子涨落是随时间变化的，长时间后趋于一稳定值；耦合部分的电阻对分回路及耦合部分的量子涨落都有影响，但按照新方法算出的结果要比按以前理论算出的涨落小。

| Abstract: | Based on the physical mechanism of the generation of resistance, i.e. the collision of electrons with lattices, the inductive-coupled electric circuit was quantized when there exists resistance in the coupling part. Quantum fluctuations were calculated for both the component circuits and the coupling part. And meanwhile, the temperature effect was included. The result shows that quantum fluctuations change with time, but reach definite values after a long time. The resistance in the coupling part affects the quantum fluctuations both in the coupling part and in the component circuits. Compared to the former results, the quantum fluctuations derived by this new method are smaller. |
