摘要
首次在国内矿井中实地测量了９００Ｍ超高频无线电波在巷道内传播的场强变化值，描述实验地点和实测系统提供了实测数据。并结合电子轨迹描绘技术和几何光学绕射理论（ＧＴＤ），提出了传播机理的模型，通过计算机计算，得出了理论计算结果和实测数据比较接近的可喜结果。
The magnetic intensity variations of 900 M UHF radio wave propagating in the tunnel were measured for the first time in the dometic mine. And the measured data were provided. Based on combining the electronorbit protrayal technique with geometrical optics diffraction theory, the model of propagating mechnism was raised. The result shows that the theoritical calculations approxmate to the measured data.
