While this technology is promising and may eventually be useful as a diagnostic tool for basal-cell carcinoma and other skin cancers, Dr. Petri cautions that this is still basic research."We are not anywhere near being able to use this clinically," he told Medscape Oncology ."But looking into possible future applications, this technology could be used to identify patients at high risk of skin cancers or to evaluate a suspected lesion if the patient wishes to avoid a biopsy."

Petri博士表示，虽然本技术看似有用，且最后可能可以作为基底皮肤癌和其他皮肤癌的诊断工具，但这仍只是基础研究，他向Medscape Oncology表示，我们还未达可以临床运用此技术的境界，不过，著眼於未来的运用，本技术可以用来辨识高风险皮肤癌患者，或者用来评估希望避免切片之病患的可疑病灶。

First, this paper presents three girders model with double cable planes which main girder and side girder is connected by rigid arms, analyzes the dynamic characteristic of Yonghe cable-stayed bridge and obtains its natural vibration modes (i.e., frequency, damping values and the mode shapes ) by ANLSIS structural analysis program and uses these parameters as dynamic dactylogram of the intact case of cable-stayed bridge. Using the passage of random as the ambient vibration ,the dynamic properties of Yonghe Bridge is measured and the modal parameter of its 15 years after is identified and used as dynamic dactylogram of the damaged case. By the finite element analysis and locale vibration test, damaged and undamaged modal parameter is analyzed and curvature mode shape, which is sensitive to damage state, is introduced as possible candidate for identifying and locating damage in the cable-stayed bridge. Selecting the branch of part measured point from modal parameter, this paper deduces the damaged index which can detect the possible damaged location of the cable-stayed bridge deck and identifies the damaged region and degree for Yonghe Bridge. For the purpose of structural condition monitoring in in-situ , from another viewpoint, this paper introduces the method called the best optimization vector to detect damaged location and degree. The accuracy and reliability of the method presented in this paper are demonstrated by static analysis and test and the healthy state of Yonghe Bridge can be evaluated.

If you have a lot of time, you can be defended know in Baidu, examine the issue of others, if have what you can reply, give out answer, in your content, can link oneself rich customer, but such too move trace, special likelihood is regarded as advertisement to stick delete, so this is a bad plan, the best thing to do is your individual center in oneself conveys neat all and relevant data, when reply, need not link rich guest address directly, if your answer is used by others, and that individual goes to your individual center curiously to see you again is He Fang divine, the rich customer that sees you is nodded again on a bit, this chain is built, but the water mill time that this is an economize to avoid running short, if your time is insufficient, this way may be ineffective.

假如你有很多时间，你可以守在，查看别人的问题，假如有你能够回答的，则给出回答，在你的内容中，可以链接到自己的博客，但这样太着痕迹，非常可能被作为广告贴删除，所以这是下策，上策是你在自己的个人中心输齐所有相关资料，在回答的时候，不必直接链接博客地址，假如你的回答被别人采用，而那个人又比较好奇地到你的个人中心看看你是何方神圣，看到你的博客再点上一点，这个链条就建立起来了，但这是个细水长流的水磨工夫，假如你时间不足，这个招数可能不灵。

On the basement of conventional direct fan-beam reconstruction, this paper gives a newly improved algorithm-"fast filtering-backprojection". This method utilizes the symmetrical circle geometry to sample projection data, and reconstructs image on the Polarcoordinate firstly, then translates this reconstructed image onto the cartesian coordinate system with two interpolating operations so that the computer can show the result image on the VGA screen. This algorithm rebates the calculating backprojection greatly, and shortens a few times of reconstructing time than same kinds of means. With the size of image enlarging, the reconstructing time abates with 2 exponent times. In addition, according to the idea of parallel-beam, we rearrange the fan-beams and reconstruct image using parallel-beam method fastly. The rearranging constraint condition is given here.

本文首先在传统的扇束直接重建方法的基础上，提出了一个改进的快速滤波反投影重建算法，它利用旋转采集投影数据的圆周对称的几何关系，先在极坐标系统内进行图象的重建，然后通过两次内插运算再将图象转换到计算机显示方式下的笛卡尔坐标系中去，该方法将以往的直接重建方法中的反投影时所需的运算大大降低，并将重建时间比同类方法缩短了几倍，而且随着重建图象的尺寸的增大，重建时间以2的指数次方倍相对缩短，并获得了较好质量的重建图象；另外，又根据平行束投影重建图象的思想，对扇形射束进行了重排，然后利用平行束重建图象的方法进行扇束的重建，并推导了&扇束重排重建图象&方法的约束条件。

Our result shows that the best double couple solution of this Mw5.2 event is 315°,64°and 19°for strike,dip and slip angles respectively,the second nodal plane solution is 214°,74°, and 152°.The focal depth is 25±2km,suggesting that this quake occurred in the lower crust which is much deeper than most continental earthquakes.This lower crust earthquake requires that the rock should be colder than expected.We proposed generation mechanism of this deep earthquake and its implications in rock strength and thermal state.
