在中心

Firstly, according to this character, primacy central point is detected by the exploring extremum method in the windows of 3×3 pixels. Then, basing on this central point, approximate normal line at ±45°、0°and 90°angle are drew.if the minimums of normal line is at central point and the difference between the minimums and the maximum in the normal line is more than the threshold, this point is considered to the edge point of image.

首先，在3×3象素的窗口中，如果中心值为最小值，则以该点为基础，以±45°、0°和90°方向作为近似法线带，然后判断该法线上的象素最小值是否在切点上（即是否在法线的中心点上），再通过检验切点与轮廓法线上亮度极大值的差值是否超过阈值，来判断切点是否为边缘轮廓上的点。

Mr Eldon, now chairman of the Dubai International Financial Centre, still watches the region closely and says:"There is a tussle within China over who will be the leading financial centre – and that could mean they are all kept busy on domestic matters for the foreseeable future."

现任迪拜国际金融中心(Dubai International Financial Centre)主席的埃尔敦仍在密切关注这一地区，他表示："在谁将成为主要金融中心的问题上，中国存在着内部斗争——这或许意味着，在可预见的未来，他们都将忙于本土事务。"

To determine the early changes and process of formation of central polydactyly, syndactyly, and cleft hand, we experimentally induced these anomalies in the hind limbs of rat embryos and discussed the relationship among these abnormalities.

目的：在同一个病人有多种中心型多趾、并趾、裂手畸形组合常出现在各自的四肢，然而很少知道在四肢发育的过程中的趾线的异常诱导的早期变化，为了确定中心型多趾、并趾以及裂手畸形的形成过程和早期变化，我们通过实验在大鼠的下肢诱导这些异常并探讨这些异常之间的关系。

On the poetics level, using a irrational female-genesis to self-explaining; using a "body-writing" as a self-domination, making a self-realization by ways of "dark","blood","death", such as those feminine imagination; making a self-represent ion by "monologue". On cultural consciousness level, takinga self-searching on reconsidering woman's status and ending in love; taking a self-awaking by showing what a mother had "done" for daughter in order to serve and maintain man society; introducing a self-remolding through recover and rebel the man ideology; be self-awakening and oppugning the man-centre society, within its cultural "make","assimilation" to female herself.

本文从两个方面来集中分析《女人》显示出的的"女性意识"：在诗学审美形态上，以非理性的女性"创世神话"题材来解释"自我"；以"躯体写作"的方式来支配"自我"；以"黑夜"、"血"、"死亡"等"阴性意象"来认识"自我"；以"独白"的方式来表达"自我"；在文化意识形态上，以对爱情中女性地位和结局的重新思考来寻找"自我"；以"母亲"对"女儿"的"塑造"来揭示"母亲"作为男权社会的"服务者"和"维护者"形象达到警醒"自我"；对男性文化意识形态的还原和反叛来解构男性中心文化并重铸"自我"；在辨认"自我"的觉醒中将质疑引向对男性中心社会及其所预置的文化秩序和"被造"、"被同化"的女性自身。

The growth and nucleation rates of〓 cleavage face of YbYAB crystal are all very fast, because so many growth steps and growth centers were formed within only 2～3 second at the temperature near the saturate point. No spiral growth steps can be found, so growth mechanism is twodimensional nucleation. When the flux temperature increases for only 0.5℃ above the saturate point, the spiral melting holes are formed. The transformation from growth morphologies to melting morphologies is very sensitive to the temperature. When the temperature increases another 1℃, the spiral melting holes transform into two-dimensional nucleation melting holes.

YbYAB的〓解理面的生长及成核速度都非常快，在比饱和点低0.5～1℃的温度下，当生长2～3秒钟时，可以看到许多生长中心与生长台阶的形成，在较宽的台阶上还可以看到二维核的形成，没有看到螺旋中心，说明生长机理是二维成核生长；当温度比饱和点高0.5℃时，在〓解理面上形成螺旋状熔坑，这表明形貌由生长到熔化的转变与温度的关系是非常敏感的；当温度比饱和点高1.5℃时，螺旋状熔坑转变为二维成核状熔坑。

They are rooted in the Roman thermae where Roman aristocrats spent time as social activities, they usually ate, exercised, read, drink, shopped, socialized, and discussed politics there.

在国人心中，洗浴中心源自于罗马的贵族浴场文化，罗马贵族在此社交、买卖、高谈国事，并在浴场中用餐、健身，和现今国内洗浴中心并无差别。

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.
