Terror, Ideals, and Civilization,dent of conductivity of the materials involved. In fact, even for a distortionless transmission line, although an attenuation constant was present, all other basic properties of the line were independent of conductivity. The speed of propagation depended only on material properties of the line (. an他日关税重重 发表于 2025-3-27 09:08:47
