Electrostatic coupling or interference occurs when an electrically charged object approaches the input circuit under test.

带电物体接近被测电路的输入端时，就会发生静电耦合和干扰。

With this shield in place, the noise current generated by the electrostatic voltage source and the coupling capacitance flows through the shield to ground rather than through the signal conductors.

有了这种屏蔽，由静电电压源和耦合电容产生的噪声电流就经过屏蔽流到地，而不再流过信号线。
