Electrostatic actuating vibration method that is used to determine the dynamic characteristics of capacitance force nonlinearity, frequency errors and the method of compensating sensors parasitic capacity are discussed. 提出了用静电力激振法确定电容式加速度传感器的动态特性,并分析了其静电力的非线性、频率误差及补偿传感器本身寄生电容的方法。
It showed that JDM strain of T.chilonis had the highest parasitic capacity, followed with HJS and YYS strains of T. 结果表明,对烟青虫卵寄生力最高的是螟黄赤眼蜂的JDM品系,其次为松毛虫赤眼蜂的HJS和YYS品系;
This system is complex to design, has a high cost, what is more, this system produce parasitic capacity in the compound circuit. The complex level in system design will influence measurement result in sensitivity. 该系统设计复杂程度较高,成本大,而且在复杂电路中会产生寄生电容,系统设计的复杂程度直接影响到了测量结果的精确度。
