固定线圈
- Add the workpiece fixed in the coil, coil discharge at the moment have a damping pulse magnetic field decay, so that the loss of magnetic parts.
工件放入线圈中不动，线圈在放电瞬间产生脉冲阻尼衰减磁场，使工件失去磁性。 - A permanent magnet and a moving contact are fixed on a swing plate which can deflect, and the top end of the swing plate is hung on a coil brace through a spring.
永久磁铁和动触头固定在摆动板上，摆动板可偏转，顶端通过弹簧吊置在线圈支架上。 - Normal Box Series: wooden box, pallet, crate, wooden box fixed with metal band, wooden cable coil etc.
普通木包装系列：木箱、木栈板（托盘）、板条木箱、围框、电缆木盘等。 - Through analyzing the working principle of eddy geophone, seven parameter model of frequency response function was derived, where the influence of electromagnetic induction of geophone shell on induced current of fixed coil was considered.
笔者分析了涡流检波器的工作原理：综合考虑了检波器磁路系统中，外壳、磁靴等部件的电磁感应对固定线圈感应电流的影响；建立了七参数的动力学模型。 - Especially on different occasions, people have different needs on air handling. Air processing end with the fixed form such as fan coil and fresh air system can no longer meet the need.
尤其是针对不同的场合，对空气处理要求不同，固定形式的空气处理末端如风机盘管加新风系统已经无法满足要求。
