  1. The rails are affected by the skin effect for its large permeability and size. the track time constants are not constant due to the skin effect. for the calculation of the rails impedance, the method of equivalent cylindrical conductor is developed

    由於鐵軌很大的磁導率和截面尺寸，致使其阻抗在電磁暫態過程中受到了集膚效應的影響，從而使得鐵軌的時間常數在暫態過程中並非是一個常數。
  2. Skin effect is the tendency for alternating current to flow near the sruface of the conductor in lieu of flowing in a manner as to utilize the entire cross - sectional area of the conductor. this phenomenon causes the resistance of the conductor to increase. the magnetic field associated with the current in the conductor causes eddy currents near the center of the conductor which opposes the flow of the main current near the center of the conductor. the main current flow is forced further to the surface as the frequency of the alternating current increase

    表面疚是指交流電流較傾向于導體的表面傳導而非流經整個導體截面的趨勢，這些現象會造成導體的電阻提高，與導體中的電流有關的磁場在導體中心部位產生過電流而阻礙了中心部位的主要電流，當交流電的頻率增加時，主要電流的流向會進一步被推擠到導體表面。
