The notorious difficulty of giving any satisfactory definition of poetry is almost equalled by the difficulty of defining with precision any one of its kinds; and the epigram in Greek, while it always remained conditioned by being in its essence and origin an inscriptional poem, took in the later periods so wide a range of subject and treatment that it can perhaps only be limited by certain abstract conventions of length and metre.

他臭名昭著的困难给予任何令人满意的定义几乎等于诗歌是由难以界定与高精度其任何一种类型；和警句在希腊，而它始终受制于目前在其本质和起源的inscriptional首诗，在中在后期，以便广泛的议题和治疗，这也许可以只限于某些摘要公约的长度和米。

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。

In any case it is certain from the "Festal Letters" of St. Athanasius that in 331 the saint enjoined upon his flock a period of forty days of fasting preliminary to, but not inclusive of, the stricter fast of Holy Week, and secondly that in 339 the same Father, after having traveled to Rome and over the greater part of Europe, wrote in the strongest terms to urge this observance upon the people of Alexandria as one that was universally practiced,"to the end that while all the world is fasting, we who are in Egypt should not become a laughing-stock as the only people who do not fast but take our pleasure in those days".

在任何情况下，可以肯定的，由"节日字母"圣athanasius在331圣人受命后，他的羊群，为期四十天的斋戒初步的，但不是包容的，更严格的快的圣周，其次是认为在339个同一个父亲，之后前往罗马，并在更大的欧洲的一部分，写以最强烈的措辞敦促遵守本后，人的亚历山德里亚，作为一个被普遍实行的"，至去年底，虽然世界上所有的是斋戒，我们是在埃及不应成为一个笑柄，因为只有那些没有速度快，而且以我们最大的荣幸，在那些日子"。

The main objective of this research is to understand how each layout element in product visual appearance influences the overall image of the product; moreover, this similarity research is targeted at surveying the packaging of traditional crispy butter cakes sold in Tachia-Ville in Taichung Prefecture, The likeliness in layout elements would probably result in the confusion of visual identity. Through analyzing and comparing the layout elements of each vendor's product packaging, we tried to establish how traditional food vendors use similar elements and layout in packaging to achieve a certain level of likeliness to the leading product in order to create misleading perceptions in consumers' minds. From this research we discovered the main reason for causing confusion between Crispy Butter Cake vendors lies with their use of "red" as the primary coloring.
