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。

The representative families are Dryopteridaceae, Athyriaceae, Polypodiaceae, Thelypteridaceae, Selaginellaceae and Aspleniaceae. The main genera are Dryopteris, Selaginella, Asplenium, Arachniodes, Pteris, Allantodia and Plagiogyria. The top families' distribution types are cosmopolitan and pantropic ones, the main genera are pantropical ones, while species distribution type belong to the east Asia type and represents the feature of subtropics transition to warm temperated areatype. As for the order of closeness, the sequence of pteridophytes floristic relations between Songyang and the adjacent regions goes as Southwest China, South China, Central China, Japan, North China, Northwest China and Northeast China. The six upland pteridophytes next to Songyang can be put into the same natural flora because of its closest relationship. But compared with other 11 upland fern flora in China, fern in Songyang is not rich enough. There are 37 species endemic to China in Songyang.

结果表明，松阳蕨类植物共有38科72属161种7变种；优势科为鳞毛蕨科、蹄盖蕨科、水龙骨科、金星蕨科、卷柏科、铁角蕨科，优势属为鳞毛蕨属、卷柏属、铁角蕨属、复叶耳蕨属、凤尾蕨属、短肠蕨属、瘤足蕨属；科的分布以世界分布和泛热带分布为主，属的分布以泛热带分布为最多，种以东亚分布类型为主，特别是中国—日本分布类型最多，表现出亚热带向暖温带过渡的特点；本区与邻近地区蕨类植物区系关系的密切程度由大到小依次为西南、华南、华中、日本、华北、西北、东北；与邻近的6个山地蕨类植物区系的亲缘关系密切，可以划为同一自然区；与国内11山地蕨类植物区系相比，松阳的蕨类植物丰富程度不高；松阳拥有37种中国特有蕨类植物及一些珍稀蕨类植物，有较高的保护价值。

The maximum stress range after the repairs decreases by 50% to a level where cracks would not be expected to reinitiate.

Some of his oldest and closest friends criticized his plan both to him and to the press, and by the time a ministerial colleague successfully pleaded with him to visit Memphis, Tenn., to boost the cause of black sanitation workers who were on strike because of the city's refusal to recognize their union or negotiate improvements in their dire working conditions, King was almost happy for the distraction from a Washington game plan that was threatening to come unstitched at seemingly every possible corner.

但是在1968年最初的几周他的下属无法或者不愿意按照他的预想齐心协力开展这个运动使他更加意志消沉，他的一些老朋友和最亲密的朋友批评他的计划以及批评支持他的新闻界，那时他的一个部长级别的同事邀请他到田纳西州的孟菲斯去激励那里的黑人清洁工因市政不承认他们的工会和糟糕的工作条件而举行的罢工运动，马丁路德金欣然愿往以消遣在华盛顿运动看起来很大程度上可能导致失败的那种沮丧心情。

As the company's main product - both rotary joint From design to production have continued to innovation, many models adopted a new balance of mechanical seals designed to seal the end than the pressure to maintain the minimum and unchanged, optimization of the friction material composition and the use of advanced NC Processing Center, sealing performance, life has a great degree of improved technology and products so that the water quality in the average domestic leading position.

作为本公司的主导产品--旋转接头无论从设计到制作都不断努力创新，许多型号采用了新的平衡机械密封设计，对密封端面产生的比压值保持最底限度且不变；优化了摩擦副材料的组合，并采用先进的数控中心加工，密封性能，使用寿命都有了很大程度的提高，使产品的技术和质量水平均处于国内领先地位。

I thinks, should be similar to to coming to China one year game industry always reviews of state of affairs of development of network game estate especially, be in abroad, such similar exhibiting meeting, join the metropolis that postpone business to bring them individually commonly newest the modernest play and a series of modern notional sex technologies, and the CJ that sees us, all focuses are in centrally another " Ding Beili " on the body, might as well the news that reviews the concerned CJ last year, besides manufacturer news (of course the centers the look before he exhibits a stage belle of large also space gets on manufacturer news personally), report press from rich guest, outside notting have bosom of bikini belle, belle is compared greatly go all out, each exhibit stage belle big round of drinks of cool and refreshing degree reads an and his like, now year?

愚以为，应该类似于对一年来中国游戏产业非凡是网络游戏产业发展情况的一个总回顾，在国外，类似这样的展会，一般各个参展商都会带来他们最新最时髦的游戏以及一系列时髦的概念性技术，而看看我们的CJ，所有的焦点都集中在一个又一个&丁贝莉&身上，不妨回顾一下去年的有关CJ的新闻，除了厂商新闻外（当然厂商新闻也大篇幅的把目光集中在自己展台前的美女身上），从博客报道到新闻报道，无外乎比基尼美女、美女胸部大比拼，各展台美女清凉程度大巡阅之流，而今年呢？
