To improve the current situation that research on sellers' attributes has not received enough attention in the field of E-commerce study, this paper analyzes the E-commerce transaction data of cellular phones with Self-Organizing Map and explores how the match between sellers' attributes and the commodities affect the prosperity of the transactions. The findings will help sellers and manufacturers understand the market status and their own advantages and disadvantages, and they can take measures to improve their production and operation.

The results indicate that both of that of iron and steel industry exceed that of whole industry average level.In iron and steel industry,ironmaking consumes most energy and yields most pollutants.The ironmaking's net energy consumption per ton pig iron of key iron and steel works is 704 kg,about 29.5%of which is used for sinter and cokemaking and isn't reclaimed satisfactorily after enhancing the physical and chemical character of raw material.This is one of the reasons why ironmaking system consumes so much energy.

结果表明：钢铁工业的能耗、污染物排放量远高于工业部门平均水平；在钢铁工业内部，炼铁系统的污染最严重，能耗最高。1996年全国重点钢铁企业吨铁净能耗为704 kg，其中29.5 ％用于烧结和焦化工序，且在提高原料的理化性能之后，未得到充分回收和利用，是炼铁系统能耗高的一个重要原因。

In this framework, image frame, audio and text are represented, which are the three modalities in video shots as data points by the 3rd-order tensor. Then a subspace embedding and dimension reduction method is proposed, which explicitly considers the manifold structure of the tensor space from temporal-sequenced associated co-occurring multimodal media data in video. It is called TensorShot approach. Transductive learning uses a large amount of unlabeled data together with the labeled data to build better classifiers. A transductive support tensor machines algorithm is proposed to train effective classifier. This algorithm preserves the intrinsic structure of the submanifold where tensorshots are sampled, and is also able to map out-of-sample data points directly. Moreover, the utilization of unlabeled data improves classification ability.

在此框架中，视频镜头首先被表示成由视频中所包含的文本、视觉和听觉等多模态数据构成的三阶张量；其次，基于此三阶张量表达及视频的时序关联共生特性设计了一种子空间嵌入降维方法，称为张量镜头；由于直推式学习从已知样本出发能对特定的未知样本进行学习和识别，最后在这个框架中提出了一种基于张量镜头的直推式支持张量机算法，它不仅保持了张量镜头所在的流形空间的本征结构，而且能够将训练集合外数据直接映射到流形子空间，同时充分利用未标记样本改善分类器的学习性能。

The experiments show that the proposed method can use unlabeled images to improve image classification performance and is not sensitive to image geometrical transform.

Three part of research works had been carried out in the dissertation. The first part: a kind of multidentate amine modified silica gel was synthesized through the following steps:(1) introduce the amino groups onto the surface of silica-gel by the treatment of surface silanol groups withγ-aminopropyl trimethoxy silane;(2) michael addition of excess trihydroxymethyl propyl triacrylate to amino groups on the silica gel surface;(3) amidation of the unreacted double bonds of TMPTA on the surface of TMPTA modified silica gel with diethylenetriamine;(4) the multidentate amine modified silica gel was finally obtained by the reaction of amino groups on the surface of DETA modified silica gel with double bond of butyl acrylate.

Considering principles of sedimentation geology, utilizing the premise that two sequential layers (eroded and underneath uneroded layers) enjoy approximate deposition speeds, we plot with residual thickness values and thickness values of underneath uneroded layer in cross sections. By analyzing the diagram, we can not only obtain the eroded thickness of strata, but also explain the original sedimental environment of the eroded strata and the later structural erosion causes.

介绍了4种解释模型，充分考虑了沉积地质学原理，利用相邻两层沉积速率相近这个前提条件，通过在纵剖面上对剥蚀层残余厚度及下伏未剥蚀层厚度值进行坐标投点，分析它们的图形分布规律，不仅可以量化求取剥蚀厚度值，还可以对剥蚀层的原始沉积环境及造成剥蚀的后期改造作用，做出重要的地质成因解释。

The resource allocation of national insurance industry nowadays mainly has twoproblems: first, the progress of policy insurance and commercial insurance isunbalanced, which cumbers the development of agriculture, foreign trade and realestate industry to some extent;second, the resource inside the commercial insuranceis not allocated with reason, and some is wasted, which is embodied in the aspects ofinsurance supply, insurance agency, insurance demand and insurance product.

就现阶段来看，我国保险业的资源配置存在两方面的主要问题：首先，政策性保险与商业保险发展失衡，在一定程度上影响了我国农业、对外贸易和房地产业的发展；其次，商业保险资源配置在商业保险内部也存在着资源配置不合理、资源未得到充分利用以及资源浪费的现象，在保险供给、保险中介、保险需求和保险产品方面都有体现。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it.
