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。

He fine-tuned everything from top to bottom to make sure that our capacity is maximized and our voices joint in the best tonal harmony. Under his leadership, the choir shined with dazzling glamour--we had SYF Gold Medal every year, We were the only school choir honored to sing carols for the President and the public in the Orchard Road; We sang in international operas such as the Phantom of the Opera and Aida; We held concerts and operas in Victoria Concert Hall; we received the gold medal in the International School Choirs Competition in Austria; and in 1998 we published our first CD with all the songs and music written by ourselves.After graduation from secondary school and enrollment in Junior College, I started to join other clubs and interest groups to explore more wonders life has to offer. Yet my chorus connection is never lost. Due to some lovely coincidences, fattie Kwei is also the kapellmeister in Victoria Junior College and National University of Singapore.

黄胖的最大优点就是善于发挥每个人的特长，对细节掌控的非常好，如依据每个人音质和音高的不同调整站位精确到几厘米，每两音节间的停顿精确到0.1秒，有时还会依据需要对歌词做临时变声处理（亦即有些英语或拉丁语的单词不发他们正常的本音而换成别的音标，使得歌词在音乐中更加流畅），在黄胖子的带领下立才中学的合唱团每年都创造奇迹--连续数年新加坡合唱比赛第一名，圣诞节在乌节路给总统、总理、议会还有公众的1个多小时的独家献歌，负责诸多著名国际歌剧(Aida， the Phantom of the Opera等)的合唱部分，在维多利亚剧院举办音乐会、歌剧，一举夺得奥地利国际校际合唱比赛金牌，98年更是推出了我们的第一本专辑，专辑里所有歌曲和歌词都由我们自己创作。
