Compound magnetic strip : capable of magnetizing and demagnetizing , alarm doesn t function anymore after demagnetization so that buyers and commodities can get across channel exit at the same time 复合磁条:可以充消磁,消磁后不再报警,顾客和商品可同时过通道出口
Relations between the signal - to - noise , sensibility , demagnetizing factor , output of fluxgate sensor with its diameter , thickness and turns of core are discussed in this paper . the author of this paper also concluded some basic principle for the designing of fluxgate sensor . the author designed and produced two dimension sensors to prove the possibility of the miniaturization of fluxgate sensor 本文还分析了小型化传感器的实现可行性,分析了磁通门传感器的信噪比、灵敏度、退磁系数、感应输出与传感器磁芯直径、厚度和磁芯匝数的关系,论证了传感器小型化的可行性,总结了在设计磁通门传感器时所应遵循的基本原则,并且设计制作了两种尺寸的传感器,从实验角度论证了传感器小型化的可行性。
The laboratory group leader shall assign a person to clear recycling samples that are judged as cancelled or out of the storage life ; recycling piece samples shall be returned to the sintering procedure , demagnetized , and then after completion , reported for inspection according to the regular program ; any waste samples shall be sent to the keeper of the waste warehouse of the production workshop , and relevant delivery procedures need be handled by filling in the " form for disposal of samples " 判定为报废的和超出保留期限的回用品由实验室组长安排人员对样品进行清理,回用的块状样品退回给烧结工序,进行退磁处理,完成后按正常程序重新报检,废品交送生产车间废品库管理人员,办理交接手续需填写“样品处置单” 。
