摄影用的

With the American national treasure level photography master Arab League speech,"you are using your eye photography."

用美国国宝级摄影大师阿达姆的话，"你是在用你的眼睛照相。"

About 25% of women older than 40 years have dense breast tissue, which makes it particularly difficult to distinguish between healthy and tumor tissue on a mammogram."We all know that mammography is not perfect," commented Eric Winder, MD, professor of medicine at the Dana Farber Cancer Institute, in Boston, Massachusetts. This new technique could be a useful adjunct, particularly in women with dense breasts. There is already increasing use of magnetic resonance imaging in such women, he noted, and this technique might offer an alternative."Strategies for breast cancer screening are becoming more individualized, and we are moving away from a 1-size-fits-all scenario," he commented at an ASCO press briefing that he moderated.

40岁以上的妇女有大约25%有致密乳房组织，使得特别难以藉由乳房摄影区别健康组织和肿瘤组织；达那-法柏癌症研究治疗中心医学教授、Eric Winder医师表示，我们都知道乳房摄影不是最好的，这个新技术可以是有用的辅助方式，特别是属於致密乳房组织的妇女；他指出，这类妇女使用磁振造影的人数已经增加，此技术或许可以提供另一种选择；他在主持ASCO的记者会时表示，乳癌筛检策略变得个人化，我们已经不再用一体适用的方案。

We presents an accurate F method based on corresponding point adjustment.The method adjusts coresponding points according to the fixedness of projective transformed cross ratio,then calculates F matrix accurately through linear and non-linear methods. When computing intrinsic parameter,A matrix,we simplify the step,and stress on the two important parameters of A.The result will be getten through solving Kruppa equation based on SVD decomposition.In order to compute extrinsic parameters,we use linear method to get initial R and t,then apply non-linear method to accurate them.

提出了基于匹配点调整的F求精方法，先根据摄影交比不见性对手工选择的匹配点进行调整，再用线性、非线性结合的方法求精F矩阵；在计算内部参数A中，进行了一定的简化，把重心放在A中重要的两个参数上，用SVD分解法计算Kruppa方程；在计算外部参数时，首先用线性法求解R、t，然后再用非线性法迭代求精。

There are plenty of shows selling shots from Holgas for a lot more money, just that those folks don't tell me about it. Holgas sell for $14.95, brand new, here. You can see an award-winning shot made with a Holga hanging in Washington, D.C.'s Hemicycle Gallery of the Corcoran Museum of Art in their 2006 Eyes of History competition of the White House News Photographers Association here.

有许多展览贩售由Holgas相机所拍出的、价格高昂的照片，但是贩卖者不会告诉我这些作品是用什么相机拍的，因为在这里，全新的Holgas相机一台只要14.95美元(相当於500元台币不到)，你可以欣赏到许多以Holgas相机拍摄的得奖摄影作品，展出於华盛顿区的可可画廊所举办的『2006历史的双眼-白宫新闻摄影师协会摄影比赛展。

Mammography is the most common imaging modality in detecting and screening breast tumor. However, for better image contrast and spatial resolution, the patient's exposure to X-ray radiation is highter than that of the ordinary roentgenography.

乳房摄影是用来侦测与筛检乳房肿瘤最常用的诊断工具，为求得到较佳的软组织对比与解析，使用的X光照相条件比一般常规摄影具有较高的放射线剂量。

Among the footage is time-lapse photography of the ship being built over 60 days and some footage from a hand-cranked camera similar to the kind used in 1912 where he photographed Winslet and DiCaprio in between takes.

在这些影像素材中，包括有建造模型船60天的延时摄影片断，还有模仿1912年时用手摇曲柄摄像机的摄影片断，片段中是迪卡普里奥于凯特·温丝蕾。

Anyway, you have done a perfect job that nobody had done. You share a rich meal with us shutterbugs by your perseverance, spirit, and acuminous viewpoints, brilliant articles.

不管怎样，阿纲做了摄影人所没有做过的一件了不起的事情，用他的毅力、精神、敏锐的目光、精彩的文字语言带给我们摄影爱好者一顿丰盛的大餐。

Unfortunately, some of these tintypes have found their way into the market place as real vintage material.

不幸的是，一些用这种仿制的当时制作出来的锡板版摄影作品出现在了艺术市场中，就好像是真的老铁版摄影一样。

METHODS: 8 curved artificial root canals were prepared with stainless steel K files by the step-back technique, the root canals were digitally photographed, the images were analysed by the software Image-Pro Plus, the shapes and positions of the root canals were measured and analysed. SPSS10.0 software package was used for statistical analysis, paired-samples t test was used to compare the difference of the means among sample groups.

使用手用不锈钢K锉，按逐步后退法预备8个弯曲人工根管，根管预备过程中对根管及根尖孔进行微距摄影，用图像分析软件Image-Pro Plus对根管的形态与位置变化进行测量、分析；实验数据采用SPSS10.0统计软件包进行统计学分析，选用配对t检验比较组间差异。
