homogeneous layer meaning in Chinese

均匀层
均匀地层
均质层

Several numerical experiments are carried out to detect the actual steps and limitation for the velocity and depth parameter ' s ray inversion in the fourth chapter , and the we find that : a . the resolution capability of the layer ' s velocity change along both the top and bottom boundary is very poor . thus generally the vertical homogeneous layer model whose top velocity equal to that of its bottom boundary should be considered
本文的第四章通过一系列模型试验详细探讨了利用射线反演方法反演速度和深度参数的实际步骤，认为走时反演对速度层内顶部和底部速度变化的分辨能力很弱，仅仅依靠走时数据难以反演出层内顶部和底部的速度变化，故一般情况下应采用速度层底部和顶部速度相同的纵向均匀模型。
