摘　　要：采用TOPSIS方法分析了二级分压线路的输出电压与粗、细调电阻比值的变化规律.结果表明,粗、细调电阻比值为10/1时,输出电压既能很好地满足线性关系,又有一定的调节范围.The relations between the output voltage and the resistance ratio of accurately adjusted rheostat and roughly adjusted rheostat in the second class voltage division circuit are analyzed based on TOPSIS method. The results indicate that the output voltage has not only good linearity but also enough adjusting range when the resistance ratio of accurately adjusted rheostat and roughly adjusted rheostat is 10 ： 1.
