"What makes these different from conventional electronic networks," he said,"is that instead of thinking in terms of a conduction current, one should think in terms of the displacement current, which indeed can 'flow' in free space and in dielectric materials."

他解释道：&之所以会产生这些与传统电子网络不同的概念，原因是我们不是从传导电流的角度而是从位移电流的角度进行考虑的，位移电流确实可以在自由空间和在电介质材料中流动。&
