Under the control of microprocessor, this product with an oscillating implement embedded in can produce mulriple-scanning pulse electromagnetic wave with variable frequency and mulriple frequency conversion ultrasonic. Electromagnetic wave can get rid of the pests around electrical wire and ultrasonic can dispel the pests in other areas of the room. The product sends out frequency conversion signal of ultrasonic to circumambience. Once touches objects, it reflects and permeates the room. The combining of the two waves has mulriple effects on the central nervous and hearing system of the pests such as rats, cockroachs, spiders and ants. As a result, the pests would be on the rack and agonizing or even have the symptom of swivet and twitch.

它由完全内置的震荡器，在微电脑的控制下可产生多重扫描变频脉冲电磁波和复合变频超声波，电磁波主要解决电源线周围害虫的问题，而超声波是要消除室内其余区域的害虫，它向周围发射的变频超声波信号，当它碰到物体会反射，从而能充满整个房间，这两种波迭加在一起所产生的双重功效，对老鼠、蟑螂、蜘蛛、蚂蚁等害虫的中枢神经及听觉系统进行多重干扰，令其感到极度不适，恐慌不安，甚至表现出狂乱、抽搐等症状，并能使其丧失繁殖能力，迫使其逃离原地，从而达到驱赶害虫的目的。

SP. transient electromagnetic method: An electromagnetic method in which the waveform of the transmitted signal is a pulse, step function, ramp, or other form which can be considered to be nonperiodic and in which measurements are made after the primary field has stopped changing.

瞬变电磁法：一种电磁勘探方法，其中发射信号的波形是一个脉冲，阶跃函数，斜升函数或其它可认为是非周期的信号形式，且测量是在一次场停止变化后进行的。

Under the control of microprocessor, this pest repeller with an oscillating implement embedded in can produce mulriple-scanning pulse electromagnetic wave with variable frequency. It penetrates walls and transmits by the wire within walls and makes all connected wire producing pulse electromagnetic wave. By irritating the nervous systems of pests, it makes them be on the rack, physiology disorganized and the capability of procreation reduced. The pests are driving away as they are compelled to escape.

QC101型微电脑变频驱虫器：由完全内置的震荡器，在微电脑的控制下可产生多重扫描变频脉冲电磁波，它可以穿透墙壁，沿室内的电源线传播，让所有在墙中或建筑物内相通的电线都发出脉冲电磁波，刺激鼠类和其它害虫的神经系统，使老鼠和其它害虫感到极端恐慌，生理功能紊乱，繁殖能力降低，感到无法生存而逃离现场。

This thesis aimed to discuss an electromagnetic energy harvester. Motion of a fluid driven by a 30 Hz pulse pump is used to activate the electromagnetic energy harvester. The periodic motion of the fluid in the chamber causes a harmonic vertical deflection in the diaphragm on which a permanent magnet is attached. Subsequently, the vibration of this magnet induces an output voltage in a solenoid hanging above it.

中文摘要本文是探讨电磁式能量产生器的机构，此电磁式能量产生器的主要作动方式为藉由频率30Hz的脉冲马达驱动工作流体，使工作流体呈周期性的流动让帮浦腔体上致动薄膜产生周期性的上下往复运动，因此帮浦腔体内产生压力周期性的变化，在薄膜上永久磁铁的振动，使得螺旋线圈感应产生电压的输出。

It is a kind of electromagnetic mechanical device turning dispersed electric pulse signal into corresponding angle displacement or line displacement to Electric motor which by stepwise, it is one introduction that output pulse corresponding increment drive component.

步进电动机是一种将离散的电脉冲信号转化为相应角位移或线位移的电磁机械装置，它输出的角位移与输入的脉冲数成正比，是一种输入与输出脉冲对应的增量驱动元件。
