It solves the problem that the unitary contour presentation can not correctly extract face contour in a face image which suffers from scale, rotation etc. The definition of the internal and external energy function is provided. At the same time, the global matching algorithm and local matching algorithm is given. The experiment shows that this presentation and the accompanying matching algorithm can be used to extract the face contour very well. So the image segmentation can be implemented by using it.②By analyzing the recognition principle of PCA method, we can conclude that the face images coming from different surrounding consist of different face image space. This is the essential reason that makes the generality of PCA method worse. Also, we give a measurement means to measure the distance from different face image space, so we can analyze face image space more conveniently.③We also construct various scale models and rotation pose models to detect the scale and rotating angle of face image to be recognized. The experiment results show that the detecting precision is very high. So it is good for face image feature extraction and face image representation.④Similarly, we construct local feature models of face image and utilize them to detect the local feature of face image. At the same time, we put forward a novel face image local feature detection algorithm, locating step by step. The experiment results show that this method can accurately detect the location of local face feature in a image.⑤A novel face image presentation model, dual attribute graph , is put forward. Firstly, it utilizes attribute graph to present the face image, then exact the local principal component coefficient and Gabor transform coefficient of thc pixels which corresponds to the nodes of the graph as the attribute of the nodes. This representation fully makes use of the statistical characteristic of the local face feature and utilizes Gabor transform to present the topographical structure of face image. So DAG has more general property.⑥Based on the DAG presentation, we give a DAG matching function and matching algorithm. During the design of the function and algorithm, the noise factor, e. g., lighting, scale and rotation pose are considered and tried to be eliminated. So the algorithm can give more general property.⑦A general face image recognition system is implemented. The experiment show the system can get better recognition performance under the noise surrounding of lighting, scale and rotation pose.

本文在上述研究的基础上，取得了如下主要研究成果：①构造了一个通用的人脸轮廓模型表示，解决了由于人脸图象尺度、旋转等因素而使得仅用单一轮廓表示无法正确提取人脸轮廓的问题，并给出了模型内、外能函数的定义，同时给出了模型的全局与局部匹配算法，实验表明，使用这种表示形式以及匹配算法，能够较好地提取人脸图象的轮廓，可实际用于人脸图象的分割；②深入分析了PCA方法的识别机制，得出不同成象条件下的人脸图象构成不同的人脸图象空间的结论，同时指出这也是造成PCA方法通用性较差的本质原因，并给出了不同人脸空间距离的一种度量方法，使用该度量方法能够直观地对人脸图象空间进行分析；③构造了各种尺度模板、旋转姿势模板以用于探测待识人脸图象的尺度、旋转角度，实验结果表明，探测精确度很高，从而有利于人脸图象特征提取，以及图象的有效表示；④构造了人脸图象的各局部特征模板，用于人脸图象局部特征的探测；同时提出了一种新的人脸图象局部特征探测法---逐步求精定位法，实验结果表明，使用这种方法能够精确地得到人脸图象各局部特征的位置；⑤提出了一种新的人脸图象表示法---双属性图表示法；利用属性图来表示人脸图象，并提取图节点对应图象位置的局部主成分特征系数以及Gabor变换系数作为图节点的属性，这种表示方法充分利用了人脸图象的局部特征的统计特性，并且使用Gabor变换来反映人脸图象的拓扑结构，从而使得双属性图表示法具有较强的通用性；⑥在双属性图表示的基础上，给出双属性图匹配函数及匹配算法，在函数及算法设计过程中，考虑并解决了光照、尺度、旋转姿势变化等因素对人脸图象识别的影响，使得匹配算法具有较强的通用性；⑦设计并实现了一个通用的人脸图象识别系统，实验结果表明，该系统在图象光照、尺度、旋转姿势情况下，得到了较好的识别效果。

When motion is towards the location of the addressee,come is much preferable to go in English while both laiand quare common in use in Chinese.When motion is towards the location of the addressee at a past time,laimust be used in Chinese if the addressee is there at the time of utterance while qumust be used if the addressee is not there at the time of utterance.By contrast,come is used in English either when the addressee is there or when he is not there at the speaking time,while go is only used when the addressee is not there at the time of utterance. When both the speaker and the addressee serve as the figure,which is indicated by the phrases like with me/us/you in English and the phrases like he ni,he nimen,gen wo,gen womenin Chinese,come is much preferred to go for the figure"s motion,while in the same context,quis used for the figure"s motion.What"s more,come is more frequently used to indicate the figure"s movement towards a place where neither the speaker nor the addressee is located at the time of utterance,while quis often used in Chinese in the same case.

当移动体朝向听话人所在方位移动时，英语多用come，汉语可用"来/去"；当移动体在一个过去的时间朝向听话人所在方位移动时，汉语可用"来"表示听话人在说话时间仍在位移参照点，用"去"表示听话人在说话时间已不在位移参照点，而英语在两种情况下都可用come，用go则表示听话人在说话时间已不在位移参照点；当说话人和听话人一起作为移动体而句中主语只是说话人或听话人一方时，英语多用come，汉语多用"去"。

I use "we" to mean "you and I," and "you" for the reader.

我使用"我们"来表示"你和我"，用"你"来表示"读者"。

Partly it has great practical value – you can wrap it around you for warmth as you bound across the cold moons of Jaglan Beta; you can lie on it on the brilliant marble-sanded beaches of Santraginus V, inhaling the heady sea vapours; you can sleep under it beneath the stars which shine so redly on the desert world of Kakrafoon; use it to sail a mini raft down the slow heavy river Moth; wet it for use in hand-to-hand-combat; wrap it round your head to ward off noxious fumes or to avoid the gaze of the Ravenous Bugblatter Beast of Traal (a mindboggingly stupid animal, it assumes that if you can't see it, it can't see you – daft as a bush, but very ravenous); you can wave your towel in emergencies as a distress signal, and of course dry yourself off with it if it still seems to be clean enough.

一方面是由于它有着非常实际的使用价值——当你跳跃着穿越Jaglan Beta的冰冷的月亮中间时，可以把毛巾裹在身上用来取暖；在Santraginus V的灿烂的大理石沙子的海滩，你也可以躺在毛巾上，呼吸浓烈醉人的海洋蒸汽；也可以在Kakrafoon的沙漠世界里，在红色的恒星照耀下，盖着毛巾睡觉；用它做帆，在缓慢宽阔的Moth河上泛舟；在近身搏斗中打湿了做武器；包住脑袋来防止毒气侵袭或者避开Traal的贪婪虫鸣兽的喋喋不休（一种发自内心的愚蠢的动物，它总是认为如果你看不到它，它也就看不到你——蠢得像灌木，却很贪婪）；可以在紧急情况下挥动毛巾表示求救信号；当然，也可以用来擦干身体——如果它看起来还是足够干净的话。

Classical Chinese article sentences make pauses in reading unpunctuated ancient writings mediumly, it is the person that use " commonly, also " will express, also be with " sometimes, for, criterion, all, it is " express, the watch denies judgement is not "," with " not "," does not have "," not ".

文言文中的判定句，一般是用"者、也"来表示，有时也用"乃、为、则、皆、是"等表示，表否定判定用"非"、"未"、"无"、"莫"等。

And what does AD stand for?---Well, AD is the abbreviation for the Latin term Anno Domini, which means in the year of our Lord, so AD actually marks the birth of Jesus.---What about the time before Jesus was born?---Well, we would use BC, which stands for Before Christ.

I see。今年是2009年，讲得明确一点的就是AD 2009，AD表示Anno Domini这是个拉丁文的字表示西元，而西元前要用BC，也就是Before Christ，AD通常会放在年份的前面，BC要放在年份的后面，另外如果要来表示是第几世纪我们要用序数，前面要用定冠词，所以并不是21 century而是the 21st century

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。

Using different colors shows resistance specification. 4 color ring is generally carbon film resistors.its three-ring show resistance, with a color ring showing error. 5 color ring is generally Metal Film Resistors.Its four-ring show resistance,with other showing error.

就是在电阻器上用不同颜色的环来表示电阻的规格。4个色环一般是碳膜电阻，用3个色环来表示阻值，用1个色环表示误差。5环电阻一般是金属膜电阻，用4个色环表示阻值，另一个色环也是表示误差。

My days were not days of the week, bearing the stamp of any heathen deity, nor were they minced into hours and fretted by the ticking of a clock; for I lived like the Puri Indians, of whom it is said that " for yesterday, today, and tomorrow they have only one word, and they express the variety of meaning by pointing backward for yesterday forward for tomorrow, and overhead for the passing day."

我的日子并不是一周中的星期几星期几，没有被烙上异教徒神灵的印记，也没有被切分成一小时一小时，并且被时钟的滴答滴答声搅得心烦意乱。我喜欢像印度的普里人一样生活。据说，他们在表达昨天、今天、明天的时间概念时用的是同一个词，而在表达不同的具体时间概念时，他们就用手向后指来表示昨天，向前指表示明天，像头顶指表示正在过去的一天。

The split between the two groups can hardly be papered over.
