| 摘 要： | Introduction Forward modeling is commonly used in the interpretation of 2D crustal structure with wide-angle seismic reflection/refraction data. But this method not only has mass work and more subjective effects, but also cannot provide quantitative estimates of model parameter error, resolu-tion, and model uniqueness. It also cannot assure that the data consistency is the minimum of par-ticular range. In order to overcome the defects of forward modeling, Zelt and Smith (1992) have developed…
