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.

There were only 94 vascular plant species, belonging to 50 family and 75 genera. The dominant species in the communities were deciduous broadleaf species Liquidambar formosana, Robinia pseudoacacia, Ailanthus altissima, Acer buergerianum, and Celtis sinensis, evergreen broadleaf species Cinnamomum camphora and Elaeocarpus glabripetalus, and Phyllostachys heterocycla. Robinia pseudoacacia+Cinnamomum camphora community had the highest Shannon-Wiener index (1757) and Phyllostachys heterocycla+Acer buergerianum community had the highest Simpson index (0163), but no consistency was observed between the curves of H and D. For vertical structure, most communities had no significant understory stratification.

The conclusions are as follows:(1) Neologisms in each Huayu region can be classified into two major categories:self-originated and others-originated,among which the new-born words are "absolute new words" and the inherited word are "relative new words",and there are also others-originated elements in the morphemic and sense systems of new words;(2) Variation can be seen in the morpheme,formation,building and sense of new words in Huayu regions,besides individuals of new words;(3) Aggregation of current new words and compound words with one common morpheme and a same construction,together with the aggregation of synonyms and that of different senses in polysemies,reflect the relevance of the systems of new words in Huayu regions in their variation;(4) Regular participation of hinting sense of a formation element in forming and building new words is an important way of producing new sense of morpheme,and an important reason for the current emergence of words with more than one new senses;(5) Compared with ordinary words,the productivity of ways of word formation in forming new words both in general and of a particular class will change and new ways of word formation appear in Huayu regions;(6) The semantic collocation of the verbal morpheme of new verbs in a phrase has a great influence on the location of its structural center,and the complex syntactic behaviors of new verbs are related to the different processes of argument integration;(7) The processes of building new words with the same meaning differ in levels of approaches to motivation cognition,perspectives of motivation cognition,morpheme motivation and morpheme expression,etc.;(8) The lexical interaction in Huayu regions results in lexical subsystem intersections of current new words across two,three and four regions.

Also being with the metamorphic crystalline basement formed later and suffered the stronger tectonic event and the material composition reforming, being composed of the material with low density and existing the relatively weak intrinsic mechanical system, Huaxia massif was affected by the various tectonic movement in the later period, the layers inside the lithosphere interacted under action of the tectonic force, this led to the material composition and the structure regulated and changed constantly by the magmatism in the crust, underplating and faulting and folding, therefore, the ability to resist the deformation decreased with the every variation.
华夏地块变质结晶基底形成时代晚,并遭受更多更强构造变动与物质组分的改造使之物质组成密度较小,岩石圈先期固有的力学结构系统相对较弱,尤其是后期的地球大系统的历次构造运动都对其施加影响,构造动力作用下引起内部圈层间相互发生作用,导致内部物质成分、结构形态通过壳内岩浆活动、地幔底侵作用、断裂褶皱等不断的调整重组重建而变化,其每一次调整变化,都使其总体抵抗变形能力进一步降低。
