He gave him lessons four days a week after the station had closed for the night and in three weeks Edison was a better telegrapher than his teacher. 他在车站夜晚关门后,每周给他上四次课,三个星期之后爱迪生便成为比他老师更好的电报员了。
By the time he was12 he was a telegrapher and everlastingly trying to make that system of communication work better. 到他12岁时,他当上了报务员,他坚持不懈地努力尝试改进这种通信系统。
This method needs not decouple the telegrapher's equations for multiconductor transmission lines, and is also suitable to nonuniform coupled transmission lines. 该方法对于耦合传输线无须进行解耦,在处理非均匀频变传输线时也非常方便。
