1.Nonpolarized capacitor C1 and potentiometer R2, a linear taper, determine the time constant of integrator IC1B.
无极性容C1线性位器R2决 定积分器IC1B的时间常数。
2.Coloring is low of nonpolarized numberrepresentationof polypropylene film and dimensional stability poor fitting is not as a substrate of bar code labels.
