Among the various conductive fillers, carbon fibers have been proved to be a good candidate for EMI shielding. However, the electrical resistivity of a carbon fiber is much higher than the metal filler, so it must to use a greater number of carbon fibers in order to achieve the same shielding effect. In recent years, the Electroless plating is the new techniques of surface treatment of carbon fibers used to improve the electrical conductivity of carbon fiber. The copper-coated and nickel-coated carbon fibers have been proved to be a good candidate for EMI shielding.

导电高分子填充材料多使用碳纤维、碳黑及金属粉末，其中碳纤维具有高导电性、低密度及复合材料之补强特性，故本研究碳纤维作为填充材料，将碳纤维经过无电电镀处理，使其表面分别披覆金属镍及铜，增加碳纤维之导电度，混掺於聚丙烯高分子基材中，制成具有电磁波屏蔽功能之高分子复合材料，研究不同高分子成型方式与金属镀层对於碳纤维电学性质及复合材料电磁波屏蔽效益之影响。

The flow of molten metal are the forefront of the lost foam pyrolysis products, it will happen with the liquid metal reflect and affect the quality of metal liquid, if the liquid metal filling process in pyrolysis products should not rule out smoothly, it is easy to cause stomatal , Cockle, by defects such as carbon.

金属液的流动前沿是热解的消失模产物，它会与金属液发生反映并影响到金属液质量，如果金属液充型过程中热解产物不能顺利排除，就容易引起气孔、皱皮、增碳等缺陷。

Faraday's law is that when the flux in the conductor loop changes, it produces electromotive force in the conductor loop, and obeys to contour integral law , Maxwell Curl Theory is that when the magnetic intensity of a certain point in ether space changes, there produces electric field at that point in ether space, which is the field mutual production theory of "electric field produces magnetic field and magnetic field produces electric field" in the free space which everybody is familiar with, and it obeys differential law , Lorentz magnetic force is that when metal electrons cut magnetic lines, metal electrons forced by move along the conductor to form inductive current, in fact, it doesn't matter whether coil moves or magnet moves, only if there exists relative motion between magnetic field and conductor, metal electrons must cut magnetic lines, which is,"coil stills while magnet moves to the left" and "magnet stills while coil moves to the right" these two situations are the same, which both belong to metal electrons having cut magnetic lines.

法拉第定律指导体环路里的磁通量发生变化时，在导体环路上产生电动势，而且服从围线积分律；麦克斯韦旋度理论指以太空间某点的磁场强度发生变化时，在以太空间的该点产生电场，即大家熟知的自由空间里"电场生磁场与磁场生电场"之互生场理论，而且服从微分律；洛伦兹磁力指金属电子切割磁力线时，金属电子受力沿着导体漂移而形成感应电流，其实，无论线圈运动或是磁铁运动，只要磁场与导体存在相对运动，则金属电子必然切割磁力线，即，"线圈静止而磁铁向左运动"与"磁铁静止而线圈向右运动"这两种情况是一样的，都属于金属电子切割了磁力线。

For example, your fire apparatus appear some problems, slight sick Chinese medicine called get fire, western medicine called fever, maybe is the heart or small intestine problem, but out body we can check your tongue or pulse. Furthermore, autumn belong the metal, normally Chinese doctor tell us don't eat too many spicy food in autumn, otherwise is unhealthy to your lung. Because the spicy and lung both belong the metal, too much metal could cause to your lung or large intestine sick. Therefore the pneumonia and enteritis are very popular appear in autumn. Human's five emotions are also belong the five elements, like desolation belong the metal; anger belong the wood; funk belong the water; happiness belong the fire; unhappiness belong the earth. People who easily anger get liver sick easily; pavid person easily to get kidney sick; so happy cause to the heart problem, and so on.

举几个比较简单的例子，属于火性的器官出现问题，轻微的中医叫做上火，西医叫发热，可能是心脏或是小肠的毛病，但表现在身体外部是舌头干燥和脉搏异常；再有一个，秋天属于金，中医告戒我们秋天要少吃辛辣味的食物，否则对肺不好，因为辛辣和肺同样属于金，金过于旺盛会导致属于金性的肺脏或肠道异常，因此秋天人们通常容易得肺炎或肠炎之类的疾病；人的五种情绪也属于五行之中，忧伤属于金、愤怒属于木、恐惧属于水、欢喜属于火、思愁属于土，容易发怒的人容易得肝脏疾病，而有恐惧胆小的人容易得肾脏疾病，受到大的惊喜很可能伤及心脏。
