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。

看见月亮，意味着一天又过去了，在这个家庭中生活真的很累，感觉太压抑了，看着家一天天的变着，我也跟着变了，在我眼里，我活着一点意义都没有，整天和死人差不了多少，自从我的从3个人的世界变成了一个人的世界，我就学会了，面对，走进社会，我也感觉到社会的阴险狡诈。

Never Say Goodbye Bon Jovi Crossroad As I sit in this smokey room The night about to end I pass my time with strangers But this bottle's my only friend Remember when we used to park On Butler Street out in the dark Remember when we lost the keys And you lost more than that in my backseat baby Remember how we used to talk About busting out - we'd break their hearts Together - forever Never say goodbye, never say goodbye You and me and my old friends Hoping it would never end Never say goodbye, never say goodbye Holdin' on - we got to try Holdin' on to never say goodbye Remember days of skipping school Racing cars and being cool With a six pack and the radio We didn't need no place to go Remember at the prom that night You and me we had a fight But the band they played our favorite song And I held you in my arms so strong We danced so close We danced so slow And I swore I'd never let you go Together - forever Never say goodbye, never say goodbye You and me and my old friends Hoping it would never end Never say goodbye, never say goodbye Holdin' on - we got to try Holdin' on to never say goodbye I guess you'd say we used to talk About busting out We'd break their hearts Together - forever THE END by lune

In fact, it was as a consequence of field research in the Medoc that I came to understand how important culture is, viewed as lived social interactions, the symbolic and the contested, to both the construction and reproduction of the political economy of winegrowing.6 That is, differences in climate and soil can be invoked rhetorically to c6nceal the cultural and historical construction of class privilege or, in Roger Keesing's sense of mimesis (I992), subordinate populations can reproduce the very logic and hegemonic discourse of their privileged counterparts.

实际上，借助 Medoc野外研究的结果，通过社会相互作用、象征与竞争，乃至葡萄种植业的政治经济的建设与再生产，我懂得文化的重要性。即气候和土壤的差异，被夸大的吹嘘以至于隐藏起等级特权的文化与历史建设的作用，在罗杰基辛（1992）模拟的感觉里，人能与他们的特权对手重建非常逻辑和霸权的对话。

"Hazy" Good ambiguous name, yesterday in a rare fog enveloped the entire City, a very silly sense of visibility below 10 meters, just go out would be a kind of very exciting feeling, in that space of the Mist stay for a long time, feeling a boring person can not see anything, can only be seen a few zero-Mist dilute the flashing lights of the cars, you do not know what the status outside the 10 meters, or even the traffic lights, you do not know what you will face is how the situation, everything is unknown, that Mende feeling may just be time for everyone to face the unknown of a mind's instinctive reaction to fear.

"雾蒙蒙"好暧昧的一个名字，昨天一场罕见的大雾笼罩整个岛城，很懵懂的感觉，能见度低于十米，刚刚外出会有种很兴奋的感觉，在那种蒙蒙的空间里呆久了，感觉很闷，看不见任何东西，只能蒙蒙中见到几个零稀的车灯在闪烁，你可以不知道十米以外是怎样的状况，甚至是红绿灯，你也不知道你将面临的是怎样的状况，一切都是未知，那种闷得感觉，可能只是每个人面临未知时的一种内心恐惧的本能反应。

Under the new situation of new century, how to crush the political scheme that the western hostile force headed by U.S.A. continues utilizing " democracy "," free "and " human rights " of capitalist class to " occidentalize "," split up" our country, comply with mankind political trend of development of civilization at the same time, learn wildly from others strong points, develop socialist democratic politics of the distinct Chinese characteristics, reflect superiority of socialist democracy, is a subject that is worth thinking deeply.
