Abstract:To achieve the layout optimization of multiple index air-borne pseudo satellite network of ground-level and large-scale coverage, the paper puts forward pseudo satellite network in cellular wave-mode, defines and analyses the measurable indicator of network design and optimization. Considering the weakness of wide-range search ability of genetic algorithm and the problem of the optimal result that is easy to fall into local optimum and so on, the suitable means of network layout optimization is that using empirical method to roughly determine the value range that affects network performance parameters, after that using genetic algorithm to conduct the multi-parameter optimizing on network performance indicators in small zones. Finally, research and analysis on performance of network which was optimized should be carried out. The simulation results show that the proposed cellular wave-type network can achieve wide area coverage and ensure the availability of PDOP in service area. By comparing the two approaches which are a combination of empirical approach first and genetic algorithm next and empirical approach merely and directly to optimize network performance, the conclusion can be achieved that the former approach can improve the efficiency and performance of network optimization.

2019年CATTI二级笔译英译汉真题及参考答案

2019年CATTI二级笔译英译汉真题及参考答案 【第一篇】 So where there is financial connection, we see that rapid improvements in quality of life can quickly follow. In our modern context, there are several important channels to achieving this greater financial connectivity. I want to highlight two today: increased capital mobility and increased financial inclusion. First, enabling capital to flow more freely. Allowing capital to flow across borders can help support inclusive growth. Right now, foreign direct investment —FDI — is only 1.9 percent of GDP in developing countries. Before the global financial crisis, it was at 2.5 percent. Making progress on major infrastructure needs will require capital flows to rise again and to be managed safely. Greater openness to capital flows can also bring down the cost of finance, improve the efficiency of the financial sector, and allow capital to support productive investments and new jobs. Challenges that come with opening up capital markets. Thankfully, we know from experience the elements that are required for success. These include sound financial regulation, transparent rules for investment, and attention to fiscal sustainability. We also need increased financial inclusion. A few numbers: close to half of the adult population in low and middle-income Asia-Pacific economies do not have a bank account. Less than 10 percent have ever borrowed from a financial institution. And yet, we know that closing the finance gap is an “economic must-have” for nations to thrive in the 21st century. IMF analysis shows that if the least financially inclusive countries in Asia narrowed the finance gap to the level of Thailand — an emerging market economy — the poverty rate in those countries could be reduced by nearly 4 percent. How can we get there? In part, through policies that enable more women and rural citizens to access financial services. The financial gender gap for women in developing countries is about 9 percent and has remained largely unchanged since 2011. There is no silver bullet, but we know that fintech can play a catalyzing role. In Cambodia, for example, strong public-private partnerships in supporting mobile finance has led to a tripling in the number of micro-financial institutions since 2011. These institutions have now provided loans to over 2 million new borrowers, representing nearly 20 percent of the adult population. Many of these citizens had never had a bank account. Now they can save for the future and perhaps even start a business of their own. These are ideas that can work everywhere. But countries have to be willing to partner and learn from each other. That is one of the major reasons why last October, the IMF and World Bank launched the Bali Fintech Agenda. The agenda lays out key principles — from developing financial markets to safeguarding financial integrity — that can help each nation as it strives for greater financial inclusion. 【第一篇参考答案】

论文投稿常见问题答疑 根据我国的职称评定情况,论文发表数量是职称评定考核很重要的指标之一,所以每一个职称评定者肯定都经历过论文投稿的摧残。论文投稿并不是每一位科研工作者所了解的领域,所以在投稿的过程中,肯定或多或少产生了一些问题。以下常见问题,供论文投稿或有论文发表需求的人借鉴: 一、投稿以后时间越长是否说明录用的机会越大? 文章是否录用不是取决于时间的长短,而时间长可能是负责编辑的工作量偏大或者日程与审稿产生冲突,而来不及参与审稿。 二、收到审稿意见,是否意味着录用的可能性较大? 如果编辑回复你审稿意见,那说明给了你机会,一般只要认真听取审稿意见,认真修改自己的文章,一般录用的机会比较大,但是仍有修改后有退稿现象。 三、收到杂志邀请审稿邮件,是否需要回复? 一般审稿系统都是自动,如果收到此类邮件,只需要直接确认审稿或者拒绝审稿。拒绝审稿时,可能需要填写原因或推荐别的审稿人,如果是系统自动则无需回复。 四、一般论文的投稿主要方式有哪些? 投稿主要有三种方式:纸质投稿、EMAIL投稿和网上投稿。纸质投稿一般需要将稿件打印几份,邮寄给期刊编辑部,有的期刊还要求需要论文的软盘或光盘;EMAIL投稿就是将论文以附件形式发给编辑;网上投稿就是期刊有网上投稿系统,将论文在网上提交。一般国内期刊要求纸质投稿的比较多,而且还有一些国内期刊在纸质投稿后,同时还要将稿件EMAIL给编辑,国外期刊也有要求纸质投稿的,但似乎越来越少,毕竟航空信件来往费时费钱,所以逐渐被网上投稿所取代。EMAIL投稿国内国外期刊都有,但考虑到网络安全和技术的发展,EMAIL投稿也会逐渐被网上投稿所取代。网上投稿是国外期刊所采用的主要形式,有直观、迅速和方便的特点,但在网上投稿前需要在网站注册一大堆信息,第一次使用网上投稿会感到麻烦,但可以将你第一次注册的信息保存到WORD文件,以后再网上投稿时大部分信息复制粘贴就可以了,一定要记住注册的帐户名和密码,否则耽误你的投稿计划哦。 五、如何获取所投刊物的投稿须知? 1. 现刊获取投稿知: 如果你(或图书馆)有杂志的现刊,那么一般每一卷的第一期或最后一期杂志中就会有投稿须知; 2. 网上获取投稿知: (1)对上了网的杂志,直接进入主页; (2)从数据库中获取 被万方数据库收录的期刊可在其数字期刊网页查到相关的信息,包括简介、稿约、征订启事、主要栏

投稿的相关问题

投稿的相关问题 1.投稿之前 1)请确认您是否已仔细阅读了我们的“投稿须知”? 2)请确认您的文章摘要是否已按照杂志社的要求,以“目的—方法—结果—结论”的结构编写? (如果不知道怎么写,请参考我们已刊登过的文章) 3)请确认您的参考文献是否按照我们杂志的要求编写? 4)请确认您是否准确选择了投稿栏目? 2.稿件投到编辑部后的流程是什么样的? 1)稿件投到编辑部后,会根据稿件所属的栏目下发到各个栏目编辑手中,每个栏目编辑会独立 处理这篇稿件。 2)栏目编辑会对稿件进行初审,查看文章的具体内容,并据此确定外审专家。 3)通过初审的稿件会送外审专家进行外审,没有通过初审的文件会被直接退稿。 4)外审专家审回稿件后,栏目编辑根据外审专家的意见,确定上定稿会的稿件。没有通过外审 的稿件会被直接退稿。 5)定稿会上栏目编辑会详细介绍准备刊登的文章,最后采用不记名投票的方式表决,通过定稿 会的文章基本确定可以发表了,没有通过定稿会的文章会被退稿。 3.为什么有的文章初审很快,有的很慢? 要了解这一点,首先需要明确杂志社的工作时间。 1)每个月的月初,栏目编辑的主要工作是提交已经编辑好、准备发表的文章,和召开定稿会, 确定今后发表的文章。 2)每个月的月末,是杂志排版印刷的时间,这个时候编辑会对稿件做最后的校对。因此这一头 一尾都是属于编辑部最忙碌的时间,稿件初审的进度可能就会出现滞后的情况。 3)编辑部每年会收到上千篇来稿,栏目编辑都需要一一审核,工作量其实是很大的,有些时候 也会出现滞后的情况。 4)此外,如果按照要求,认真编写了摘要,可以让编辑在初审时迅速了解这篇稿件,快速确定 是否通过初审。而一篇摘要混乱的文章,编辑还需要阅读全文,这也会拖慢审稿速度。4.为什么有的文章外审很快,有的很慢? 1)为了确保作者的文章得到最权威的判定,栏目编辑需要找到合适的外审专家,对于某些新颖 的话题,寻找外审专家需要一定的时间。 2)我们的外审专家有长期在生产一线的工作者,也有院校的学者。根据不同外审专家的工作性 质,其审稿时间是不同的。这里需要注意的是,我们有一个预计外审时间,但这个时间并不准确,需要根据外审专家的实际审稿时间来定。

审稿注意事项

审稿注意事项 一、关于详细提纲(目录) 1.各卷以篇为单元并由首席篇主编负责完成。每篇稿件由篇名页(篇主编姓名 及单位、作者姓名及单位)、目录(章、节、小节)、正文(图、文、表、执笔作者)、参考文献(不重复出现、不加角标)共同组成,并符合“齐、清、定”要求。 2.篇名、章名、节名和小节名应尽量准确、简明、简短。如节名前原则上不用 再加“…(篇名)的…(章名)的”,尽量少出现“的”,不让读者费解及误解,让读者一目了然。这是审稿的重点内容。 3.根据需要,每卷的第1篇可设为“概论”,每篇的第1章可设为“概述”。内容精 练,高度概括,篇幅不宜大。各节、小节以后不再单设“概论”、“概述”、“概要” 之类的目录。可根据需要,用文字直接叙述相关内容。 二、关于书稿要求 1.《电气大典》是综合性的专业工具书,书稿总体上必须符合“编写指南”要求。 每个作者的稿件都达到此要求后,篇主编和卷主编就容易组织审稿和统稿,书稿质量就高。 2.书稿内容是作者的知识、经验和成果的结晶,是集体智慧的体现,强调“内 容新颖、实用便查”,供大家学习、借鉴、查阅、启迪、创新,“开卷有益,使人易晓”。不宜写有关发展历史、发展过程、意义、挑战、目的、必要性、观点思考、问题探索、改革方向及政策方面的内容,少写理论性、概念性、公式推导性内容,避免写成教科书、丛书、论文、个人专著。要经得起广大电气工程师和专家教授的长期实践检验。 3.图号、表号、公式号是按篇章顺序编号,如图3.8-6表示第3篇第8章的第 6个图。图、表和文字一起构成稿件。 4.交稿时,必须有打印稿和光盘。手写稿未能刻成光盘的稿件,请加以标注。 5.还没有填写作者登记表的作者,请一定要在交稿时补上。发稿酬、出书署名 和制作“荣誉录”时以此为准。 中国电气工程大典编委会 2006年8月2日

考博英语翻译及写作真题解析与强化练习-英译汉【圣才出品】

第一章英译汉 第一节考博英语英译汉部分考核要求和试题分析 一、考博英语英译汉部分考核要求 全国博士生入学考试英语翻译题(英译汉部分)的类型一般分为四类:语句翻译、段落翻译、篇章翻译和文章中划线句的翻译。 英译汉的部分,以段落翻译居多,其类型一般也分为语句翻译、篇章翻译(就一个主题进行说明、描述和论证)。对文章中划线句进行翻译的形式出现的较少。 根据原国家教委1992年颁布的《非英语专业研究生英语教学大纲》规定,博士生“英语入学水平原则上应达到或略高于硕士生的通过水平”。而硕士生英译汉教学要求是“能借助词典,把有相当难度的一般性题材文章译成汉语,理解正确,译文达意。笔译速度达到每小时350个左右英文单词。”汉译英的教学要求是“能借助词典,将一般难度的短文译成英语,无重大语法错误,笔译速度达到每小时250个左右汉字。”目前,国家对博士生入学英语考试未作统一规定,由各院校自行安排。因而,博士生入学考试英语翻译的考核标准和要求只能参照硕士生的要求。如天津大学主要是考查汉译英,要求将一般性题材的汉语短文在正确理解基础上翻译成规范、通顺的英语。译文要求忠实原文,表达基本正确,无重大语言错误。 现在,普遍的情况是要求考生将一篇近400词的英语短文中有下划线的5个句子翻译成汉语。主要测试考生能否从语篇的角度正确理解英语原句的意思,并能用准确、达意的汉语书面表达出来。更加注重在特定的语境下和联系上下文理解句子或句群的意思。形式越来越灵活,强调考查学生对英语的运用能力,能力测试的趋势增强。

二、考博英语英译汉部分试题分析 通过对国内主要重点院校近年来翻译部分的变化趋势进行分析,总结出题的特点,把握出题规律。对博士生在英语方面应该具备的能力和水平的总体认识的变化,极大的影响了题型的结构和各部分分值的变化。由于各个院校自己命题,院校之间差异较大。 (一)题型的选择和分配 1.连续多年不考英译汉或汉译英。如北京大学2000年至2006年的博士入学试题中没有考翻译题。清华大学2002至2006年试题上也没有。上海交大在1999年、2002年、2003年也没有考察英汉翻译。 2.基本只考汉译英。天津大学(分值为25分,且多年未变)。 3.基本只考英译汉。如东北大学、成都电子科技大学、厦门大学等。 4.同时考察英译汉和汉译英。如中国社科院研究生院、中国人民大学、南京大学、武汉大学、湖北联考等。 (二)出题及选材的特点 各个学校在选材上有自己的特色,通常结合学校自身实际,对材料有不同的“好恶”。但大体上呈现一些共同的特点和发展趋势。表现在: 1.体裁多以议论文为主。如武汉大学2004年的英译汉部分谈论computer and its problems。2004年中国社科院博士入学考试的考察内容为社会文明与个人的行为方式,采用的是议论文的形式。 2.所选材料多来自于经济学、社会学、教育学和计算机科学等。2004年中国人民大
