在模拟电路中，一般可分为输入电路、中间电路、输出电路、电源电路、附属电路等几部分。每一部分又可分解为几个基本的单元电路，而单元电路又是由各种元器件构成。还可用画框图的方法对整机电路进行分解，将电路按功能分成若干单元电路，找出它们之间的联系，搞清每一单元内元器件的作用，及每一单元电路的组成，进而了解单元电路之间具有何种关系，从而对整体电路有完整的了解。从静态到动态模拟电路中各种晶体管、集成电路是电路的核心，而它们在工作中需要建立静态工作点，才能实现对交流信号的放大作用。

Cable laying temperature lower than 0 ℃, bending radius: multi-core cable or 15 (D + D), a single cable 20 or more (D + D), (D for cable diameter, D) for the conductor diameter.

　　HYV主要用于语音信号传输。结构：导线：实心退火铜线。铜线直径为：0.4，0.5，0.6，0.7mm。绝缘：高密度聚乙烯，并按照全色谱标准标明绝缘线的颜色绝缘线对：把单根绝缘线按照不同的节距扭绞成对，以大限度减少串音，并采用规定的色谱组合以便识别线对。

一个OB的执行被另一个OB中断时，操作系统对现场进行保护，被中断的OB的局部数据压入L堆栈（局部数据堆栈），被中断的断点处的现场信息保存在I堆栈（中断堆栈）和B堆栈（块堆栈）中。中断程序不是由逻辑块调用，而是在中断事件发生时由操作系统调用，因为不能预知系统何时调用中断程序，中断程序不能改写其他程序中可能正在使用的存储器，中断程序应尽可能的使用局部变量。编写中断程序应越短越好，减少中断程序的执行时间，减少对其他事件处理的延迟，否则可能引起主程序控制的设备操作异常。
