Based on geological radar penetrating practice for soil and stone dam hidden dangers of reservoirs in northwestern loess areas and from the variations of the disturbance , pore ratios and water contents of the soil bodies in the percolation positions , the authors analyzed the variations of geological waveform characteristics and waveform phase axis continuation , and summed up the graph characteristics of the percolation hidden dangers in different periods 摘要通过西北黄土地区水库土石坝渗流隐患探地雷达探测实践，从渗流部位的土体扰动、空隙比、含水量的变化入手，分析探地雷达波形特征变化、波形同相轴连续性的变化，总结了渗流隐患不同时期的探地雷达图像特征。
Based on experimental research on electrical property of waterflooded rock we have found that variation of salinity has much effect on rock resistivity , and it makes that relation curves of complex resistivity and in - phase resistivity of rock under single frequency with water saturation are characteristic of u - style curve , just like relation curves of waterflooded rock resisitivity with water saturation , but salinity variation has little effect on rock dispersion property 摘要通过水淹岩石岩电特性的实验研究发现，地层水矿化度的变化，对岩石电阻率幅值的影响较大，致使单一频率下的岩石复电阻率幅值和同相电阻率也会象常规电阻率一样，随着含水饱和度的变化，出现" u "形曲线，而相对而言，地层水矿化度对岩石频散特性的影响较小。
