矿井感应通信机车插入损耗及专用线理论研究

给出了在矿井中利用电机车架空线进行感应通信时，架空线负载（即电机车）引起的手稿损耗的定义，计算了插入损耗和无负载时的电磁波传输损耗并对比了这两种损耗，可知插入损耗是非常大的，这说明了使用专用感应线的必要性，架设专用感应线后，矿井隧道中将存在一个插入损耗和传输损耗都比较小的波模，利用该波模进行感应通信是可行的。

Theoretical study of the insertion loss of electric locomotive and the ded icated line of indu ctivecommunications in mine tunnels

The authors give the definition of insertion loss of electric locomotive in inductive communication through trolley wire in a mine tunnel and compute insertion loss and transmission loss. After contrasting the two losses, we know that the insertion loss is very large and it is necessary to use dedicated induction line. If a dedicated line is erected, there is a wave mode of which insertion loss and transmission loss are smaller, which can could be employed for inductive communication.
