过零点 meaning in English
zczeo cossing point
zczero cro ing point
zczero crossing point
Examples
- The key of this method is that get the time when current value equal zero beforehand , and try to make the circuit break at that time
达到这个目的的思路是求取短路电流的过零点，试图在过零点切断电路。 - Judgment of the point of zero passage is the key factor involved , and a higher sampling frequency should be adopted when the method is applied on situations of large signal amplitude
其中过零点判定为关键技术，当用于信号幅值较大场合时应尽量提高信号采样频率。 - This paper uses " virtual neutral point method " to measure the " zero crossing " , then the soft deal " zero crossing " to get the six key position to commutate
本文采用虚拟中点的方法来识别反电势过零点，然后对过零点进行处理得到无刷电机换向的六个关键位置。 - Mostly , traditional arithmetic of image edge detection distill edge using gradient maximum or zero - crossing which base on gray discontinuousness on edge . they are affected easily by noise
传统的边缘检测算子大都是基于边缘的灰度不连续性利用梯度局部最大值或二阶导数过零点来检测边缘，容易受噪声干扰。 - The program is written by assemble language to control the movement of the vacuum circuit breaker with pma . the program also can monitor the environmental temperature , control voltage , closing displacement , zero point of contactor voltage
用汇编语言编制程序对配永磁机构的真空断路器的分、合闸进行控制，同时对其运行的环境温度、控制电压、合闸位移和触头间隙电压过零点等状态进行实时监测。
