文中导出了误差的计算公式,并由此决定了误差变化的时间常数。
to minimize the effects of dielectric absorption on current measurements, avoid applying voltages greater than a few volts to insulators being used for sensitive current measurements.
为了尽量减小介电吸收对电流测量的影响,避免向进行灵敏电流测量时所使用的绝缘体施加大于几伏的电压。
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.
在实际工作无法避免这种情况时,可能需要经过几分钟、有时甚至几个小时,介电吸收引起的电流才会消散。

applications for measuring voltage from high resistance sources: capacitor dielectric absorption and electrochemical measurements.
各种高阻源电压测量的应用 :电容器的介电吸收和电化学测量等。
for example, more than four rise times are generally required to settle to within 0.01% of final value, due to dielectric absorption in insulators and other second-order effects.
to minimize the effects of dielectric absorption on current measurements, avoid applying voltages greater than a few volts to insulators being used for sensitive current measurements.
为使电流测量时的电介质吸收影响减到最小,用来做对极小的电流测量的绝缘体,应避免施加大于数伏的电压。
dielectric absorption is calculated from the residual voltage value, as described in the previous paragraph.
