　　2.485信号线可以使用平行线作为布线，也可以使用非屏蔽线作为布线。由于485信号是利用差模传输的，即由485+与485-的电压差来作为信号传输。如果外部有一个干扰源对其进行干扰，使用双绞线进行485信号传输的时候，由于其双绞，干扰对于485+，485-的干扰效果都是一样的，那电压差依然是不变的，对于485信号的干扰缩到了小。

光看定义，电动势是比较抽象的，不太好理解。可以顾名思义把电动势理解成让电子产生运动趋势的一种本领，一种能力。好比处于高处水池里边的水，老想流出去，流到下游去这样一种趋势。又好比说一个人很会赚钱，口袋老是装了满满的人民币，这种也是一种能力。发电过程，电动势也反应发电机把机械能转换成电能的一种能力本领。有本领有能力，不做事，相当于能力体现不出来，也等同于没有能力，好比上边说到有赚钱能力的人，并没有把钱花掉，和穷人没有两样一个道理。

Plastic insulated power cable insulation layer for plastic power cable. The commonly used plastics are polychlorinated, polychlorinated and poly. Plastic cable structure is simple, easy to manufacture and process, light weight, easy to install and lay. Therefore, it is widely used as medium - low - voltage cable, and has the tendency to replace the viscous impregnated oil-paper cable. Its major drawback is the existence of dendritic breakdown, which makes it used at higher voltage.
