| 摘要: |
| 本文考虑趋肤效应，从理论上给出了 Faraday 筒的瞬态特性。分析表明，Faraday 筒有一个与其结构有关的本征频率ωc，当被测信号频率 ω<<ωc时，Faraday 筒的瞬态特性函数是一常数；当ω≥ωc时，Faraday筒的瞬态特性函数是一常量和一衰减振荡量的叠加，此时，Faraday 筒对被测信号有严重畸变。 |

| Abstract: |
| The surface-action is Considered here and the transfer characteristic of Faraday cup is derived theoretically. The analysis shows that there is an eigen frequency ωc，which is related to the structure of the cup. When ω(measured signal's frequency) 《ωc，the transfer characteristic function is a constant; but when ω≥ωc，the function is the sum of a constant and a decreasing oscillation term. On the latter condition，the cup would cause the distortion of the measured signal. |
