摘　　要：博斯蒂克反演不存在人为的干扰因素,能较好地反映地电断面的基本特性,经常被用作现场实时处理和构建间接反演的初始模型。由于数据具有一定的分散性,而求导数运算对这种分散性尤为灵敏;所以在做反演之前应先对实测数据做预先处理,这样能使结果更理想一点。经数据预处理前后的反演结果对比,论证了数据优化后的博斯蒂克反演能为MT资料的精确反演提供更好的初始参考模型,具有推广使用的价值。there is no man-made interference factors in the Bostick＇ inversion, the basic characteristic of the electrical section can be well reflected, it is often used as a real-time processing at the scene and to be build the initial model of indirect inversion, because the data has certain dispersion, But derivative operation is particularly sensitive for this dispersion, So before doing the inversion should be do in advance with the measured data, this can make the result to be more ideal, Compared with the inversion results of before and after data preprocessing, demonstrated the Bostick, the optimized data inversion can provide with better initial reference model for accurate inversion of MT data, Promote the use of value.
