The mechanism of consumer segmentation is based on demographic, psychographic factors such as age, ethnic background, value, belief and emotional subtlety. It seems no longer apt to probe for buyer's motivation. If we understand core groups precisely better, the "New Values"-driven approach will make them buy.

消费市场区隔化，是以人口统计与心理描绘诸如年龄、种族背景、价值、信仰与细微的情感洞察等作为调查机制，然而，这样作法已经无法探测买家的购物动机，如果行销人愈能精确地理解核心族群，那麼「新价值」驱动的品牌行销法则愈能让卖家掏钱购物。

The microfracturing process of Jinping marble specimen in Sichuan province under uniaxial compression is recorded by using the testing scheme. Quantitatively investigated the propagation and coalescent of cracks at meso-scale with digital technology, the basic geometric information of rock microcracks such as area, angle, length, width, perimeter, are obtained from binary images after segmentation. The failure mechanism of specimen under uniaxial compression with the quantitative information is studied from macro/micro scopic perspective. The result shows that during the damage of the specimen the distribution of microcracks in the whole specimen are still subjected to exponential distribution with some microcracks concentrated in certain regions.

应用于四川锦屏大理岩预制裂纹试样中进行单轴压缩破坏全程的数字化试验，对微裂纹的萌生、生长及贯通过程进行数字化定量分析，得到试样在受荷过程中微裂纹的面积、方位角、长度、宽度和周长基本几何数据，从宏细观角度描述了岩石试样单轴压缩过程中的破坏机制，并分析得出试样单轴受压破坏过程中虽然微裂纹在某些区域集中，但在整个试样中微裂纹的统计分布依然是服从某一指数分布的这一结论。

Principle of least squares,digital image segmentation,digital image treatment and digital image identifying were applied into the research of wood science in this research,the wood cell image of annual ring from annual center to wood edge was analyzed,the modified level set method was applied to segmentate cell image precisely for the first time,the identifying of wood cells and hexagon simulation for wood cells were accomplished with active contour model,which had important potential application value in deepening the research of wood properties to a further step,moreover,had an important significance for improving comprehend on wood micro-properties and enlarging the applicable range of wood.

本研究将最小二乘原理、数字图像分割、数字图像处理、数字图像识别应用于木材科学研究，分析了从年轮中心到木材边缘的年轮的木材细胞图像，应用改进的水平集方法准确分割细胞图像，应用活动轮廓模型完成了对木材细胞的识别，并完成了木材细胞六角形仿真，对木材材性的深入研究等领域中有重要的潜在应用价值，对提高木材对微观性能认识，扩大木材的适用范围，具有重要意义。

The question's semantic comprehension model combines many natural language processing techniques, including Segmentation and Part-Of-Speech Tagging, the confirmation of the question type, the extarction of keywords and extending, the confirmation of the knowledge unit, Through these works, the intention of the user is holded, which greatly helped the last work of this system. The FAQ-based question similarity match model is implemented by sematic sentence similarity computation, which is improved by our system, this model can answer frequently-asked question fastly and concisely.The document warehouse-base automatic answer fetching model fistly deal with the document warehouse beforehand and construct inversed index, then use high efficient information retrieval model to search in the base and return some relevant documents, lastly, we use answer extraction technique to get the answer from these relevant documents and present it to users.

问句理解分析模块采用分词和词性标注、关键词提取及扩展、问句类型类别确定等自然语言理解技术，实现对用户提问意图的准确理解；FAQ 库问句匹配模块主要采用本系统改进的句子相似度计算方法来实现用户问句的解答，该模块主要用于实现用户常问问题的快速、准确解答；学科文档库答案自动获取模块在对学科文档库建立倒排索引的基础上，采用高效的信息检索模型对索引库进行检索，返回与用户查询表达式相似度较高的文档作为候选文档，针对从文档中直接获取答案难度较大这一问题，本系统采用答案抽取技术来实现问题的最终回答。
