摘　　要：介绍了用经验算法记忆LJ型铝绞线和LGJ型钢芯铝绞线电阻、电感、线芯结构的方法。分析了速记方法的理论基础以及推算数据与实际数据的偏差。指出了速记方法在电工作业现场的实用性和方便、快捷的特点。This thesis gives a detailed introduction of a pithy formula,which applied to memo-rized the technical data of aluminium twisted wire and steel cored aluminium,such as resis-tance,inductance,constitution of line core,with the help of experience coefficient.It also analy-ses the origin of the pithy formula and experience coefficient,and presents the physical prospect accordingly.Moreover,it sums the pithy formula up by putting the electric theory into practical operation,which would useful in design,installation,circulation and maintenance used for twisted wire rapidly and accurately.
