For instance, a metallic shield inside the phone provides good RF shielding but also very good heat dissipation as well.
比如，一个金属屏蔽电话内提供了良好的射频屏蔽也很好的散热。
Inductance coupling is the most important from power cable with metallic shield to communication lines when they are parallel with in a long length.
在平行长度较大时，带金属保护套的电力电缆对通信线路的干扰主要取决于感性耦合。
