如果切换系统中会混合出现小电流、高电压和高频信号，屏蔽则非常关键。
Shielding may be essential in a switching system if a mixture of low current, high voltage, and high frequency signals are present.
通过使存储单元呈现非常高的电阻来对所述单元编程，使得当施加读取电压时在导体之间不再流过电流。
The cell is programmed by rendering the memory cell very high-resistance, such that current no longer flows between the conductors on application of a read voltage.
在测量电阻率非常高的材料时，背景电流可能会引起测量误差。
When measuring materials with very high resistivity, background currents may cause measurement errors.
