摘要
在高频信号的传输过程中 ,传输线的分布电感和分布电容不容忽视 .以磁各向异性的毕奥 -萨伐尔定律 ,以及由此定律而求出的在各向异性磁介质中载流直导线磁场 ,作为论述该研究的基础 .从而由公式 ε=L| d Idt| ,求出在各向异性磁介质中有一定横截面的同轴电缆的分布电感 .
During the transmission of high-frequency signal ,the distributed inductance and the distributed capacitance of transmission line should not be over-looked. The present work is based on Biot-Savart law of magnetic anisotropy and also on magnetic field of current-carrying straight conductor in anisotropically magnetic medium solved from this law.From formula ε=L|dldt|,the authors solve the distributed inductance of coaxial-cable with definite cross section in anisotropically magnetic medium.
