Changing neither the length ofoverlapping gap nor the Angle of turning corner can assure the rise in shielding effectiveness, rather the specific changing trend is related to frequency range.
改变车身缝隙搭接部分的长度和拐角角度并不能保证提高其屏蔽效能，具体变化趋势与频率范围有关。

However, in far-end crosstalk, its sub-channels exist still a lot offrequency spectrum overlapping and increase error-rate.
在远端串扰时，其各子信道仍然存在着较大的频谱重叠，使误码率增加。
