Capacitors For this application should therefore be selected to have minimal dielectric absorption. 用于采样保持的电容器,其介质吸收应尽量低。
In cases where this practice is unavoidable, it may take minutes or even hours in some cases for the current caused by dielectric absorption to dissipate. 设若实际不能避免,可以用几分钟甚或数小时来驱除电介质吸收引起的电流。
