| 摘 要： | 利用折射波场的特点，研究隐伏层，建立不同性质中间层的临界方程和隐伏层形成条件的公式．研究表明，隐伏层形成与剖面中每个地层的厚度、波速、以及折射面的倾角有关．厚度薄而波速低的中间层容易形成隐伏层．还用τ－ｐ变换方法来识别和提取隐伏层的视速度与截距时间，并给出了模型的结果．

| Abstract: | This paper studies hidden stratum on the basis of analyzing the characteristics of refraction wave field. The critical equations of intermediate layers with different natures and the condition formula necessary for the formation of hidden stratum are derived. Research results indicate that generation of hidden stratum depends on the thickness and velocity in each layer as well as the dip angle of the refractor.Low-velocity thin intermediate layer tends to form a hidden stratum.Identification of hidden stratum and determination of apparent veloctles and intercept time for refracting layers are also researched by τ-p transformation.In addition,some calculation results of modeling are given. |
