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.

Anxious to see the garden before dark, and slightly inebriated by my success in entering the palace alone, I did not bother this time to make my presence known at the lodge, but walked boldly in, I could just see in the distance what looked like a tall rockery, and had quickened my step, when I was rudely arrested by a woman's voice. It was no fairy either, come to complain of the arrival of some disgusting creature to pollute her pure maidenly precincts, but an extremely aggressive old lady carrying a large green kettle, who informed me that I had no right to come poking my nose in there, that I had better get out at once, and who was I anyway?
恰此时一名女士猛地叫住我,然后开始责备我不该闯进来,好像我这浊物男子玷污了她那女儿般圣洁的派出所--她可不是警幻仙子,而是一个凶悍无比的老太太--她拎着个大水吊子,铜绿色的,告诉我"闲杂人等不得入内",叫我立刻离开,又问起我的身份来。

These antennas can cover GSM900/DCS/PCS/UMTS operation. In the chapter 2, the antenna is designed based on the concept of monopole antenna. Furthermore, the antenna structure have two radiant paths and coupled each other at tail end to do impedance matching. In addition, to raise distance between radiation plane and ground will avoid capacitative effect effectually. In the chapter 3, the antenna is designed based on the concept of planar inverted-F antenna. Furthermore, that the antenna structure have two radiant paths and coupled each other at tail end to do impedance matching is similar to chapter 2. But there is a difference in them. We can choose the short position to change input impedance at this structure. In the chapter 4, the antenna is designed based on the concept of planar inverted-F antenna which takes coupled-fed. It will produce the first mode and high-order mode near the frequency, 900MHz. The feature of this type is to reduce the volume effectually. This antenna can not only cover GSM900/DCS/PCS/UMTS operation but maintain good radiation efficiency. Finally, we will compare three antennas, and develop procedure with industrial view, and propose the prospect of the GSM/GPRS antenna in PND, as a conclusion.

The results showed that: with the regression analysis of Betula platyphylla, Pinus koraiensis, Abies nephrolepis, Picea koyamai var koraiensis, and Betula costata, there was a significant negative correlation between neighborhood interference index and the growth (0.40~0.89) and the correlation extent depended on the neighborhood influence zone and slope. The neighborhood influence zone corresponding to maximal regression coefficient R~2 was the neighborhood influence radius. Based on the linear subsection regression between neighborhood interference index and influence zone of five species, the neighborhood interference index increased with the increasing zone and there was a previous increasing trend in a certain scope, while the increasing trend slackened beyond the zone. The neighborhood influence zone corresponding to transition point was the neighborhood influence radius. The neighborhood interference index positively correlated with the neighborhood influence zone and the range of R~2 was 0.40-0.64. With the analysis of tree cores of Juglans mandshurica, Fraxinus mandshurica at middle and lower slope in a plot which was fostered in 1995, the distance which the growth release farthest neighborhood and object stub was judged, thus the neighborhood interference radius was inferred. According to the studies, we found that the neighborhood interference radius was different among different trees, even if the neighborhood interference radius of the identical tree species also had the difference at different slopes.
结果表明:通过对白桦、红松、冷杉、红皮云杉和枫桦树种进行邻体干扰指数与生长量回归分析发现,邻体干扰指数与生长量呈显著负相关(0.40~0.89),相关程度因邻体影响范围和坡位而异,R~2达到最大值所对应的影响范围即为邻体影响半径;通过对白桦、红松、冷杉、红皮云杉和枫桦树种进行邻体干扰指数与影响范围的线性分段拟合,邻体干扰指数随影响范围的增加而增加,其在一定的范围内上升较快,而超出该范围后上升的幅度变慢,变化的转折点所对应的影n向范围可以判定为邻体影响半径,线性回归显著(0.40~0.64);通过对1995a抚育的胡桃楸、水曲柳样树进行研究,分析邻体树种的中坡位和下坡位的生长锥芯,判断产生生长释放的最远邻木与基株树桩所对应的距离,推断邻体影响半径;根据研究发现,邻体影响半径因树种不同有一定的差异,即使同一树种的邻体影响半径在不同坡位也有一定的差异。

You have destroyed your vow to Eul when you met on that fateful summers noon as a young and lost map developer who didn't have a true purpose in the world and decided to ask those with more wisdom because you were afraid of being unable to live up to the great expectations bestowed upon you, down at the serene windy lake with it's glassy surface and lone fisherman in a small and easily overturnable boat hovering quite near the center worrying about feeding his family and the deers trotting off in the distance being jealously eyed by small rabbits who envied their youthfulness but at the same time were glad they were such innocent symbols of cuteness that were sometimes ignored by the American MEDIA, you have destroyed the oath you took with him as he decided to leave the glowing jeweled crown with the more exuberant youth of his dying generation.
在那个命运中的夏午,当时还是一个年轻且彷徨的地图开发员的你破坏了你和Eul的约定。因为你在世上没有一个确定的目标。所以你决定去请教那些更有智慧的家伙们,因为你无法承受如此大的期待而你为此感到恐惧,低着头看着碧波荡漾的湖水、那玻璃一样的湖面的非常靠近中心的位置有一个乘着简陋的随时都有沉船危险的轻舟的孤独的渔夫正在为养活他的家庭而感到担心。林中的小鹿们踏着碎步而在另一边小兔子们则充满嫉妒地注视着它们。兔子们羡慕它们的活力同时又为自己的可爱能作为纯真的象征而感到高兴。因为有时这一点能够迷惑美国媒体,你已经破坏了你和他在他决定把镶嵌着炽热宝石的皇冠留给更有朝气的年轻人作为他的继承人时的誓约。

Comparing size distribution of trace elements at haze weather and the normal weather discovered that,Ca、Ti、Fe、Cr showed significant enrichment in the small size particle at the haze weather:Cu,As didn't have different at such two kind of weather conditions;Zn、Mn、Pb appeared bimodal even trimodal distribution,whose suggested that there were a long distance transmission in originations of such three metals.
对比正常天气下的金属元素的粒径分布,发现:Ca、Ti、Fe、Cr 等元素在灰霾发生时细粒径上有明显的富集: Cu、As 在两种天气条件下区别不是很大:Zn、Mn、Pb 等元素在两种天气条件下均出现双峰甚至多峰分布。由此推断 Zn、Mn、Pb 的来源中可能存在长距离传输。
