通过对瞬变电磁勘探法中常见的几种干扰因素的分析，提出了相应的解决方法，用程控天线法和随机双极性采样法抑制干扰具有良好的去噪效果．在实际中，只要根据具体情况选择适当方法，就能有效地抑制电磁噪声的影响．无论采用哪种方法，最后采用提取特征不变量的方法进行处理后，均可以得到更好的效果．实验结果表明，测量曲线的质量较以前有很大提高．

From analysis of the noise sources which interfere transient electromagnetic method (TEM), the following methods are used to reduce them, programmable receiving antenna and stochastic ambipolar synchronous pulse. Both methods are very effective. And their results can be further improved by the distilling eigenvaiue method. Experimental results show that the curve quality has been improved a lot.
