double charge meaning in Chinese

双倍收费

Industrial users with transformer capacity above 315kva should apply double charge system : basic charge + power charge + interest rate adjustment charge
变压器容量在315kva以上的工业生产用户应执行两步制电价:基本电费+电量电费+利率调整电费。
The combined motor vibration sensor which is held manually with double charge amplifier placed inside and with frequency compensating circuit is designed based on the existed press - electricity accelerator of vibration and the measuring vibration system of charge amplifier in the paper
本文在现有振动压电式加速度计、电荷放大器测振系统的基础上，设计了手持式内置微型双电荷放大器和频率补偿电路的一体化发动机振动传感器。
The design method of the double charge amplifier are worked out based on the requirement of the sensor for testing circuit and the effect of sensor for work environment , the method of compensation of the frequency being extended is studied , and the butterworth filter of five order which is adapted itself is designed creatively by the isppac in chapter three
第三章从敏感元件对测量电路的要求和工作环境的影响出发，提出了双电荷放大器的设计方案，研究了频率拓宽补偿的方法，使用isppac创新设计了自适应butterworth5阶低通滤波器。
