两路比较器的输出端与R-S触发器的置位和复位相接，从而决定芯片3脚输出端的电平状态。当芯片2脚（/TR端）输入信号电压低于1/3Vcc时，N1输出端为“0”，R-S触发器被置位，芯片3脚变高电平，（在复位信号未输入之前）并保持；当芯片6脚输入电压高于2/3Vcc时，N2输出端为“1”，R-S触发器被复位（在置位信号未输入之前）并保持。芯片4为优先复位端（低电平有效），不用时可接Vcc。显然，作为开关电路应用时，只要控制芯片2脚电压低于1/3Vcc，电路处于“开”态（3脚为“1”）；控制芯片6脚高于2/3Vcc，电路即处于“关”态（3脚为“0”），即为开关（双稳态）电路。

三相异步电动机的基本接线。三相异步电动机绕组出来的六根线可以分为两种最基本的接法：三角形△接法和星形接法。六根线=三个电机绕组=三个首端+三个尾端，万用表测量同绕组首尾端相通，即：U1—U2，V1—V2，W1—W2。1，三相异步电机三角形△接法。三角形△接法就是将三个绕组首尾端依次相连，构成三角形。接法：2，三相异步电机星形接法。星形接法就是将三个绕组的尾端或者首端相连，另外三根线作为电源接线。

性阻抗为100Ω的双绞屏蔽电缆STP-100Ω(forFF&PROFIBUS-PA)onepair18AWG则应用于FF、PROFIBUS-PA总线，常用18AWG导体。485总线由于其布线简单，稳定可靠从而广泛的应用于视频监控，门禁对讲，楼宇报警等各个领域中，但是，在485总线布线过程中由于有很多不完全准确的概念导致出现很多问题。
With the same negative level transmission, when in the light, their impact on the two wires are the same, thus reducing difference at the receiving end can block this (minus operation performed can be understood as a difference of two way). It can be seen from the principle of double stranded lines that the purpose of double stranded lines is to transmit. Therefore, when we make the joint of the twisted pair, we must not separate the two different transmission lines, otherwise it will greatly affect the transmission of the network.
常用于城市地下电网、发电站的引出线路、工矿企业的内部供电及过江、过海的水下输电线。在电力线路中，电缆所占的比重正逐渐增加。电力电缆是在电力系统的主于线路中用以传输和分配大功率电能的电缆产品，其中包括1-500KV以及以上各种电压等级，各种绝缘的电力电缆。
