本文研究了矿井中漏泄电缆电磁波传播问题,给出了场分布公式解及单线模式和双线模式传播常数数值解。现场实测表明文中所给理论成果正确。
The problem of EI~,{ wa.ve propagation along a leaky coaxial cable with self-supporting wire located in a straight tunnel has been thoroughly studied. Distribution of EM fields related to the leaky slot inside the tu^uel is formulated; and the mode equatior~ derived is solved by approxi- mation for the propagation coristants of both mor^ofilar and bifilar modes. Experiments carried out in an actual tunnel confirm the theoretical results given by this paper.
