E-commerce in China Co mputer Engli sh09计科1班201190504张小倩Electronic CommerceElectronic Commerce, referres to as the EC. E-commerce is a wide range of commercial trade activities in the the Internet around the world,based on browser / server application mode, both buyers and sellers are not met to develop various business activities, consumers online shopping, business to business model for online transactions between households and online electronic payments, as well as a variety of business activities, trading activities, financial activities and related service activities.Some people find it useful to Categorize electronic commerce by the types of entities particpating in the transactions or business processes. The e-commerce model refers to using the Internet to carry out operations achieved operating income; The traditional view is that enterprise e-business models, summarized as: B2C (Business to Consumer), B2B (Business to Business), C2B (Consumer to Business), C2C (Consumer to Consumer), B2G (Business to Government), BMC (Business Medium Consumer), ABC (Agents Business Consumer) seven kind of business model.The three categories that are most connonly used are: Consumer shopping on the Web,often called business-to-consumer(or B2C)Transactions conducted between businesses on the Web,often called business-to- business(or B2B)Transactions and business processes that companies,governments,and other organizations undertake on the Internet to support selling and purchasing activities With the rapid development of the domestic Internet, the numbers of users increase, the use of the Internet for online shopping and consumer bank card payment gradually come to our life, the market share is also growing rapidly, e-commerce sites are endless.From the classification of a new point of view to analyze. From the traditional differences in point of view of the type of the body of the e-commerce activities of the e-commerce activities classify, To develop enterprises e-commerce activities to a certain extent lacks of significance, because enterprises can be easier to know are the four e-commerce model, but can not own the revelation of how to conduct business activities derive. And the "B" side here on behalf of the enterprise may be wondering whatever type people.

计算机英语论文（中英双语）[精华]

稀疏表示计算机视觉和模式识别从抽象技术的现象已经可以开始看到稀疏信号在电脑视觉产生重大影响，通常在非传统的应用场合的目标不仅是要获得一个紧凑的高保真度表示的观察信号，而且要提取语义信息。

非常规词典在字典的选择中扮演了重要的角色，衔接的差距或学习、训练样本同来获得自己提供钥匙，解出结果和附加语义意义信号稀疏表示。

理解这种非传统的良好性能要求词典把新的算法和分析技术。

本文强调了一些典型例子：稀疏信号的表现如何互动的和扩展计算机视觉领域，并提出了许多未解的问题为了进一步研究。

稀疏表现已经被证明具有非常强大的工具，获取、表示、压缩高维信号的功能。

它的成功主要是基于这个事实，即重要类型的信号(如声音和图像，稀疏表示很自然地就固定基地或串连这样的基地。

此外，高效、大概有效算法说明基于凸优化一书提供了计算这样的陈述。

虽然这些应用在经典信号处理的铺垫下,已经可以在电脑视觉上形成一个我们经常更感兴趣的内容或语义，而不是一种紧凑、高保真的表示。

一个人可能会理所当然地知道是否可以有用稀疏表示为视觉任务。

答案很大程度上是积极的：在过去的几年里，变化和延伸的最小化已应用于许多视觉任务。

稀疏表示的能力是揭示出语义信息，大部分来自于一个简单但重要的性质数据：虽然照片所展示的图像是在非常高自然的空间，在许多同类应用中图像属于次级结构。

也就是说他们在接近低维子空间或层次。

如果发现一个收集的样本分布，我们理应期望一个典型的样品有一个稀疏表示理论的基础。

然而，想要成功地把稀疏表示应用于电脑视觉，我们通常是必须面对的一个额外的问题，如何正确选择依据。

这里的数据选择不同于在信号处理的传统设置，基于指定的环境具有良好的性能可以被假定。

在电脑视觉方面，我们经常要学习样本图像的任务词典，我们不得不用一个连贯的思想来贯穿工作。

因此，我们需要扩展现有的理论和稀疏表示算法新情况。

自动人像识别仍然是最具有挑战性的应用领域和计算机视觉的难题。

在理论基础实验上，稀疏表示在近期获得了显著的进展。

对英语学习没有兴趣。

更有甚者连二十六个英文字母都写不全，再加上从心理上厌恶甚至抵触英语的学习。

学习稍好些的同学也只是认识一些简单的日常常用单词，掌握的词汇量普遍较少，更没有养成良好的学习习惯。

1.2教材问题在教材的选取方面，如今的计算机专业英语教材往往较为陈旧，与现在飞速发展的计算机科学技术严重脱节，缺乏最新的科技动态和流行术语等，这就使得很大一部分学生失去了继续学习英语的兴趣，让他们误以为即使是学了，将来对他们的专业学习也没有多大帮助。

导致一些学生干脆放弃了对计算机英语这门课的学习。
