检零 meaning in English

null detection
zero-detection

The hall zero - magnetic flux system can eliminate the influence of the temperature and the constant - current power of the hall element on the measurement results
霍尔检零系统可以补偿温度和霍尔元件恒流源电流的变化对测量的影响。
The hall zero - magnetic flux principle ( ie . a closed - loop principle ) is adopted to deduce the formula of the steady - state error for the hall zero - magnetic flux system , and the conclusion that the larger the amplifier amplification in the hall zero - magnetic flux system , the smaller the steady - state error is reached
摘要采用霍尔检零原理（即闭环原理）推导出了霍尔检零系统的稳态误差表达式，得出了在霍尔检零系统中放大器的放大倍数越大稳态误差越小的结论。
