拖尾的

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。

In the ***, all types and fundamental principles of Radon transform are summarized systematacially. This *** starts from the general linear Radon transform, and then researches how to use the damped least square method to find the solution of the forward transform. However, the least squares smoothing effect will lead to a certain degree of trails in the data of Radon domain, which led to the application\'s limitations. After that the implementation in Radon domain and relative merits of linear Radon transform, parabolic Radon transform and polynomial Radon transform which have time invariance are introduced, the conjugate gradient method that can solve numerical solution is also given. And then the high resolution Randon transform is discussed, it introduces the regularization theory and Bayes principle into inversion, which successfully remove the negative affect caused by discrete Radon transform. Finally, we introduce the optimal weighting similar coefficient Radon transform, which adapt to the time variant quality of hyperbolic Radon transform.

本文系统总结了Radon变换的各种类型及其基本原理，从τ- p变换(即一般线性Radon变换)出发，研究利用阻尼最小二乘平方法求解其正变换，但是最小平方法的平滑作用会导致Radon域数据存在一定程度的拖尾效应，给这种方法的应用带来了很大的局限性；然后先容了具有时不变性的线性、抛物和多项式Radon变换在频率域的实现及其优缺点，给出了求解其数值解的共轭梯度算法；接着讨论了高分辨率Radon变换，它把正则化思想和贝叶斯原理引进到了反演中，很好的克服了离散Radon变换产生的截断效应对结果的不利影响；最后先容了适应双曲Radon变换时变性质的高分辨率最优相似系数加权Radon变换。

More formidable is that developers not only depressed prices, the company is also planning to pay for a certain amount of risk mortgage payment, advance or bear part of the advertising costs, As for the clearing agent company is planning to delay the delay, even if property sales performance is very good, the general planning companies rarely get retained.

更厉害的是，开发商不仅压低价格，还要求策划公司缴纳一定数额的风险抵押金，垫付或承担部分广告费用，而对于策划公司代理结算则是能拖则拖，即使楼盘销售业绩很好，一般策划公司也很少能拿到尾款。

objective to investigate staining methods for two-dimensional gel(2-de)electrophoresis in multidrug resistance of gastric cancer.methods cultured vincristine-resistant human gastric cancer cell line sgc7901/vcr and its parental cell line sgc7901.variant amount protein of those cells were separated by 2-de.gels were stained with silver nitrate or colloidal coomassie brilliant blue,and scanned by image scanner.results well-resolved,reproducible 2-de patterns of sgc7901/vcr and sgc7901 were established.silver staining was better when protein sample amount was low,overloaded protein will interfere resolution of the maps.gels stained with colloidal coomassie brilliant blue had more protein spots numbers and abundance without apparent trails when increased loading protein sample.conclusion two staining methods were influenced largely by the sum of protein samples,properly selection may be helpful for further study with proteomics in multidrug resistance of gastric cancer.

Usually it does not matter whether the reflections being mapped are primary but rather whether their attitude is indicative of the attitude of the appropriate portion of the section, so that the tailing produced by the many short-path peg-leg multiples does not detract seriously.

通常，所要成图的反射波是否是一次波无关紧要，而它们的形态是否能表示剖面的部分形态却是非常重要的。所以，短程微屈多次反射波产生的拖尾对剖面质量的影响不大。
