We're uncertain at this point whether this slowdown after the most recent recession is going to be temporary, as it was after preious recessions before 1990, or whether it will be longer term, such as we saw after the recession in the early '90s, said Aaron Catlin, also a CMS economist and the lead author of the study, which appears in the current issue of Health Affairs.

Aaron Catlin，也是CMS的经济学家，即将在保健事务的最新一期发表研究文章的主要作者。他说"我们并不确定这种发生在经济衰退以后的医疗费用减慢趋势是否暂时的。就像1990年前的衰退所看到的，或者是否更长时间。"

In view of crosswell and 3D VSP layout, we use high resolution Radon transform based on Cauchy distribution to perform Radon transform for hole data. In this process, we study discrete dip overlay operator, improve damping factor that affects Radon energy convergence in order to let Radon energy converge, 6 resolve leggy in Radon data, and decouple smoothing effect among each energy group, we use Cauchy distribution to regularize data, let energy focus on one point, and improve Radon resolution. All these work well in wavefield separation. Finally, by inversion results and model trial, we verify the feasibility and stability of this method.

在Radon变换原理分析基础上，采用基于柯西分布的高分辨率线性Radon变换对井孔数据进行Radon变换，其间通过对离散倾角叠加算子求取的研究，及对影响Radon能量收敛的重要参数阻尼因子算法的改进，使数据在Radon域以能量团的形式呈现，得到很好的收敛效果，基本解决了Radon域数据的一定程度的拖尾现象，消除了各能量团之间的平滑效应，采用柯西分布来规则化数据，提高了Radon域的分辨率，Radon域能量也收敛到一个点上，有利于上下行波或纵横波波场分离。
