摘要:
研究表明,电阻-真空电容器电路中的电能衰减涉及多重弛豫过程,其时间常数差异显著。该现象通过使用真空电容器进行测量,以消除极板间电介质的影响(聚丙烯电容器也表现出类似行为)。尽管将麦克斯韦方程组应用于此类电路存在困难,一个简单的唯象模型仍能解释这一行为。这些结果将促使我们修正对电路物理的理解,尤其对使用电容器作为传感器采集精密数据的应用(如量子测量和介电谱学中所见)产生特别影响。
英文摘要:
The decay of the electrical energy in a resistor-vacuum capacitor circuit is shown to involve multiple relaxation processes, with dramatically different time constants. This is measured using a vacuum capacitor to eliminate the effect of a dielectric between the plates (polypropylene capacitors are shown to exhibit similar behavior). A simple phenomenological model accounts for this behavior in spite of the difficulty in applying Maxwell's equations to such a circuit. These results will lead to a revision of our understanding of the physics of circuits, having particular impact on applications that use capacitors as sensors in collecting precision data (such as found in quantum measurements and dielectric spectroscopy).
