统计与预测论文怎么写范文初中英语作文

数理统计是数学系各专业的一门重要课程。随着研究随机现象规律性的科学—概率论的发展，应用概率论的结果更深入地分析研究统计资料，通过对某些现象的频率的观察来发现该现象的内在规律性，并作出一定精确程度的判断和预测；将这些研究的某些结果加以归纳整理，逐步形成一定的数学概型，这些组成了数理统计的内容。　　数理统计在自然科学、工程技术、管理科学及人文社会科学中得到越来越广泛和深刻的应用，其研究的内容也随着科学技术和经济与社会的不断发展而逐步扩大，但概括地说可以分为两大类：⑴试验的设计和研究，即研究如何更合理更有效地获得观察资料的方法；⑵统计推断，即研究如何利用一定的资料对所关心的问题作出尽可能精确可靠的结论，当然这两部分内容有着密切的联系，在实际应用中更应前后兼顾。但按本专业的总体设计，我们的数理统计课程只讨论统计推断。数理统计以概率论为基础，根据试验或观察得到的数据，来研究随机现象统计规律性的学科。本课程的目的是让学生了解统计推断检验等方法并能够应用这些方法对研究对象的客观规律性作出种种合理的估计和判断。掌握总体参数的点估计和区间估计。掌握假设检验的基本方法与技巧。理解平方差分析及回归分析的原理，并能运用其方法和技巧进行统计推断。　　Mathematical Statistics Department of Mathematics are all an essential professional With the study of random regular scientific phenomenon - the development of probability theory， applied probability theory the results of more in-depth analysis of statistical data， through the phenomenon of certain frequency of observation to discover the inherent regularity of the situation and must make accurate degree of judgment and prediction; some of these studies will be summarized the results of collation， and gradually form over a certain type of math， these form the contents of mathematical 　　Mathematical statistics in the natural sciences， engineering， management science and the humanities and social sciences are more and more widespread and profound application of the content of their research with the science and technology and economic and social development and gradually expand， but in a nutshell can be divided into two major categories: ⑴ trial design and research， that is more reasonable to study how to more effectively access to observation data; ⑵ statistical inference， namely， how to make use of certain information on the issues of concern to the extent possible， accurate and reliable conclusions， of course， part of the contents of these two closely linked， in practical applications should take into account before and However， according to the professional design， our mathematical statistics courses are offered only to discuss statistical Mathematical statistics to probability theory based on experiment or observation in accordance with the data obtained to study the statistical regularity of random phenomena of The purpose of this course is to enable students to understand the testing methods such as statistical inference and to be able to apply these methods of research subjects to make a variety of objective law and reasonable estimates and Grasp the overall parameters of the point estimates and interval Hypothesis testing to master the basic methods and Understanding of bad-square analysis and regression analysis of the principle， and can use its methods and techniques for statistical

众所周知，词语搭配逐渐开始在语言学及应用语言学领域占据一个比较重要的地位。如今搭配成为语料库语言学领域较为繁荣的方而。很多研究人员在这一领域有兴趣，语料库现在依赖于现代计算机技术，它可以运行数千万字的文本。现在，基于语料库的研究都集中在对数量足够大的自然语言词汇重复模式方面的深入探讨。本文将基于语料库讨论商务英语中关键词汇的词语搭配。论文共分为五个部分。在第一部分中，将把本论文的研究背景详细阐述，同时也将明确指出本论文的目的和意义。同时也会对论文的组织结构进行概述。‘文献回顾中，总结了语料库和语料库语言学相关的文献，提供了搭配的相关信息以及它的具体定义和关键词等。这是我们研究的基础数据收集程序。通过计算列出数据，同时处理结果，并以科学和系统的方式加以分析。词表将被计算出来后，根据结果和比较，同时确定关键字。对于选择出来的四个关键词将被讨论，集中在词语搭配方面。最后，对商务英语语料库中的关键词的搭配研究会作出一个总结，同时并为进一步研究该建议。It is well-known that collocations are gradually beginning to occupy a relatively important place in the field of linguistics and applied Nowadays collocations become the flouring area of corpus A lot of researchers are interested in this Corpora now relies on the modern computer technology， which can make the running texts of tens and thousands millions words Recently， corpus-based research has focused on the importance of recurring patterns of lexis by looking at cUbktbTA蛛bUCz%^Lh

在过去的20多年里体裁分析一直吸引着语言学家的注意力，他们通过体裁分析研究了多种不同种类的话语。本文通过研究中国人和英语本族语人所写的英语硕士论文结论部分的体裁结构，志在从中发现它们的不同，从而提出一个模式来帮助中国研究者提高研究论文的写作能力。本研究是以Bunton 1998和2005的研究为参考的。为了进行研究，先建立了两个语料库，一个是中国研究生写的40篇英语硕士论文，另外一个是以美国和加拿大的研究生写的40篇英语论文。研究发现大多数的结论都包含介绍性的重述、研究空白的确定、实践应用蕴含及研究建议、未来研究的建议和结论重述。除了两篇英语本族语人所写的英语硕士论文外，所剩下的所有论文结论都把介绍性的重述看做是一个必须的语步;研究空白的确定是一个主要的语步，它占据着结论部分的大半篇幅，出现在了所有以论文为取向的80篇论文里，因此中英作者都一致认为这个语步是必须的而不是可选择的。研究还发现在这些研究对象中有两种建议，一种是对未来研究的建议，另一种是对现实应用的建议。中英作者尤其是英语作者把对未来研究的建议看做独特的语步。Academic discourse has generated enormous interest among linguists working in different areas and using different methodologies since the 1980s and different kinds of discourses have been studied in the scop of genre This thesis aims to empirically investigate， with reference to Bunton (1998， 2005)， the structure of Conclusions of MA thesis for possible generic differences between the concluding sections of research theses composed by MA candidates in Chinese universities and their counterparts 因FJsagDEHJyAWA

语言的一个重要特性是交际性，当交流频繁甚至“地球村”也将走进我们的生活时，毫无障碍的便利的交流就显得越来越重要。尽管古人云“读万卷书，行万里路”，但那毕竟是少数思维活跃、经济宽绰的仕宦的事；现在可不一样了，一个普通的市民坐上几个小时的飞机就可以到桂林度假，一位文化不是很高的手艺人可以常年在上海、北京打工等等，但所有这些，没有普通话这张通行证可就行不通了。我们常听到因为语言隔阂闹笑话的事，那可是轻者造成误会，重者耽误大事。 几千年来，语言文字面对的是人际交流，计算机的出现，使语言文字的服务对象从人际交际拓展到人机交流。现在，中文信息处理技术已是高科技的重点之一，语言文字的规范化、标准化的应用是研究水平的中文信息处理技术的先决条件，决定着中文信息处理技术发展的速度，它是关系到我们国家能否走上“信息高速公路”的问题。因此，推普还在推动我国整个高新技术发展，增强国力方面扮演着一个重要角色。 教育的全部目的就是生成全面发展的人，培养新世纪的合格公民。内含着丰富儒家文化的汉语言、优美动听的普通话对形成一个人的健康人格、精神底蕴和审美的生活方式有着不可低估的影响。生命全程心理语言学的研究表明：人的发展性言语状况是人的生理发展、心理发展和健康发展的“晴雨表”，言语行为的健康与否明显反映在心理上，并涉及到人的生理健康和人类的社会健康。我们应把推普和人的健康与发展结合起来，培养善于交流、精神强健的中国人。 上个世纪末英国文化委员会出版过一本叫做《英语的未来?》的学术性著作，通过实证考察和数据分析，并采取未来学的推断模式，预测世界语言格局将会重组，汉语将在21世纪名列世界语言六强，并在调整后的语言世界中发挥更大的作用。我们当然不会为一位英国人的预测而沾沾自喜，但理智告诉我们：中国综合国力的日益强盛、汉语言的独特优势、儒家文化的蓬勃生命力，必将使汉语不断兴盛。我们有理由相信，推普工作将更加自觉，更加富有成效。

新知识的接受，数学能力的培养主要在课堂上进行，所以要特点重视课内的学习效率，寻求正确的学习方法。上课时要紧跟老师的思路，积极展开思维预测下面的步骤，比较自己的解题思路与教师所讲有哪些不同。特别要抓住基础知识和基本技能的学习，课后要及时复习不留疑点。首先要在做各种习题之前将老师所讲的知识点回忆一遍，正确掌握各类公式的推理过程，庆尽量回忆而不采用不清楚立即翻书之举。认真独立完成作业，勤于思考，从某种意义上讲，应不造成不懂即问的学习作风，对于有些题目由于自己的思路不清，一时难以解出，应让自己冷静下来认真分析题目，尽量自己解决。在每个阶段的学习中要进行整理和归纳总结，把知识的点、线、面结合起来交织成知识网络，纳入自己的知识体系。

可以按照自己的实际生活去写的。要是不会写的话也是可以去请教一下老师的，毕竟老师比较懂一些的，还有就是个可以去请教品优刊。看你自己那个方面就去问那个。
