The result shows that the improved Snake Model can quickly converge the concavity region and the more complex region,and has decreased the dependence of the result of segmentation to the initial value and the influence of noise point to the boundary.

结果表明，改进的Snake模型能迅速地收敛到深凹陷区域和更复杂区域，且减弱了分割结果对初值的依赖性和噪声点对边界的影响。

By using the swirling strength method,the vortex structures excluded the effect of shear were shown clearly,and were concentrated in the coniform area of the central mixing flow field.With increasing Reynolds number,swirling strength increased and the coniform area became narrow.

利用旋涡强度法分析流场清楚地显示出排除了剪切作用的涡结构主要集中在混合层中心的锥形区域，随着Reynolds数的增大，旋涡强度的值不断增大而锥形区域不断变窄。

Astronomers have partially solved the problem of looking at objects near to a star's bright glare by inventing the coronagraph, which focuses all the incoming light around a dark spot in the telescope's innards, neatly clipping off most of the central starlight and passing on much of the planetary glow.

天文学家用日冕仪一定程度上解决了观测恒星强光附近物体的难题。日冕仪精巧地阻挡了进入望远镜中央区域的绝大部分恒星光，让更多的行星光进入望远镜。这样一来，日冕仪就能专注于分析望远镜内部圆形黑暗区域周围的入射光。

Experimental results show that the algorithm can segmentalize ROI effectively, CR is higher than 30, PSNR of the whole image is higher than 42 dB, and the object keeps original fidelity. Inter-frame CR is about 7, background has cumulative error and PSNR is higher than 40 dB.

实验结果表明，该算法在帧内能有效地划分感兴趣区域，压缩率在30以上，峰值信噪比在42dB以上，目标无失真；帧间压缩的压缩率在7左右，背景区域有误差累积，但整体图像的峰值信噪比都在40dB以上，目标无失真。

For the multifractal method, there is still no standard being set up to determine the threshold anomaly of metallogenic prognosis by the soil elements. This paper presents a calculation method using the cumulative frequency of elemental contentsnumber of deposits. The anomaly area obtained by this method can well identify the most of known deposits. Meanwhile, by this method some blank abnormal areas which are worthwhile to do further anomaly inspection have been identified.

多维分形方法下土壤元素成矿预测的异常下限值确定尚无标准，文中采用元素含量矿床数目累积频率的计算方法，基于该方法提取的成矿异常区域较好地识别出了绝大多数已知矿床，同时识别出了值得作进一步异常查证的空白异常区域。

The lack of consistent high Poisson′s ratio (≥0.30) shows that widespread partial melt does not exist within the curst, but does not exclude the presence of local partial melt.③There is an obvious thickened zone of the mantle transition zone compared with IASP91 standard value which varies from 10 km to 26 km in Qiangtang terrane. The anomaly suggests that the temperature is about 100 ℃ to 260℃ lower than global average value within the mantle transition zone, and it may be attributed to the presence of a subducted slab within the mantle transition zone.

缺乏高的泊松比(≥0.30)分布表明青藏高原东南缘的地壳不存在广泛的部分熔融，但是不排除局部部分熔融的存在；③青藏高原东南缘的羌塘地体内存在一个比较明显的、异常变化范围为10～26 km的地幔过渡带增厚区域，其对应着地幔过渡带内100℃～260℃的温度降低，可以推断与此异常区域的地幔过渡带内存在俯冲的板块有关。

The Darts Problem is this: for a given R and D, determine what values should be associated with a dartboard's R regions in order to maximize the smallest score unattainable by throwing D darts.

现在来说明掷镖游戏这道谜题的要求了：对每一个我们给的R与 D 的值，请你决定你要给飞镖靶这 R 个区域各几分，目标是在使用 D 支镖的情况下，你『不可能』得到的总分最少是多少，然后你要想办法调整 R 个区域的分数，让这个值尽可能地大。

This is the March 16 executive session, the State Council examined and approved in principle the "Central Tianjin Bohai area, Yangtze River Delta region, the Pearl River Delta city-rail transportation network planning" part. 17 journalists from the national Policy was informed that the three-city transport planning, regional passenger transport demand will meet the needs of rapid growth in the three-building resource-saving and environmental protection, modern transport systems, thus accelerating the process of regional economic integration.

这是3月16日国务院常务会议上审议并原则通过的《环渤海京津冀地区、长江三角洲地区、珠江三角洲地区城际轨道交通网规划》部分内容。17日记者从国家发改委获悉，这三个城际交通规划，将适应区域旅客运输需求快速增长的需要，在三地建立资源节约型和环境保护型现代化运输体系，从而加快区域经济一体化进程。

An online mixture of experts is used to divide the HRRP data into several regions within which online Gaussian process classifier make predictions.

通过一种在线混合专家将HRRP数据在线地分割成若干个近似平稳的区域，在各个区域内使用平稳协方差函数的在线高斯过程分类器。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
