Local cable USES manufacuring HYA, HYAT, HYAC, HYPAT, HYPA and HYA53 HYAT53, HYPA53 HYPAT53 type cable is designed for main telephone switching area, relay telephone cable, manufacuring HYA, HYAT, HYPA and HYPAT is mainly used for pipe laying, also can be used for overhead, but need to disconnect; HYAC only applies to overhead, no need for suspension lines or hooks; The HYA53, HYPA53, and HYPAT53 cables provide the mechanical strength and corrosion resistance of the cables. They can be laid in any way, which is more suitable for direct burial in rock areas. The operating temperature is -30 ~60 degrees.

:接收按钮或按键的输入信号,按照事先编好的程序,指挥马达和LCD的外围功能电路动作。
那么,单片机是如何构成的呢?()单片机是由CPU、内存、外围功能等部分组成的。
如果将单片机比作人,那么CPU是负责思考的,内存是负责记忆的,外围功能相当于视觉的感官系统及控制手脚动作的神经系统。
:单片机的构成要素我们说CPU相当于人的大脑,它却不能像人的大脑一样,能有意识的、自发的思考。
CPU只能依次读取并执行事先存储在内存中的指令组合。

三相交流电路中,它分为三相对称负载或三相不对称负载电路。
电功率计算时还要看电器负载是什么性质的负载,其中包括有纯电阻性负载,白炽灯、电炉、电热水器等,它们属于纯电阻性负载,这种电路中的电压与电流是同相位,电压与电流之间的关系,不论用瞬时值、最大值还是有效值表示,均符合欧姆定律,但一般计算都用有效值,即I=U/R。
纯电阻电路中,电阻性负载的功率因数基本上等于1,电阻元件的功率分为瞬时功率、平均功率或有功功率。
