| 摘 要： | 由于编织电缆屏蔽的特殊结构．计算其转移阻抗及内，外表面阻抗时，不能直接用 屏蔽层为圆管的Ｓｃｈｅｌｋｕｎｏｆｆ公式。新提出的编织电缆屏蔽层的简化模型，推导出转 移阻抗的扩散项Ｚｄ和内、外表面阻抗的公式，公式与Ｓｃｈｅｌｋｕｎｏｆｆ的公式不同，其中 Ｚｄ的公式与Ｖａｎｃｅ经过试验验证提出的公式一致。

| Abstract: | Because of the special shield structure of braided cables, Schelkunoff's formulas for calculation of transfer impedance, inner and outer surface impedances of cylindrical shell cannot be used for braided cables. This paper presents a simplified model for braided shield cables. Based on this model, formulas for calculation of said impedances which are different from those of cylindrical shell are derived. The formula for the diffusion term of the transfer impedance is consistent with Vance's formula which was verified by experiment. |
