毕业设计参考文献译文题目:PID控制器PID controller院(系)计算机科学与信息工程学院专业年级 09自动化 2 班学生姓名周文龙学号日期2013年3月7日PID控制器摘要:比例积分微分控制器(PID调节器)是一个控制环,广泛地应用于工业控制系统里的反馈机制。

PID控制器通过调节给定值与测量值之间的偏差,给出正确的调整,从而有规律地纠正控制过程。

PID控制器算法涉及到三个部分:比例,积分,微分。

比例控制是对当前偏差的反应,积分控制是基于新近错误总数的反应,而微分控制则是基于错误变化率的反应。

这三种控制的结合可用来调节过程系统,例如调节阀的位置,或者加热系统的电源调节。

根据具体的工艺要求,通过PID 控制器的参数整定,从而提供调节作用。

控制器的响应可以被认为是对系统偏差的响应。

注意一点的是,PID算法不一定就是系统或系统稳定性的最佳控制。

一些应用可能只需要运用一到两种方法来提供适当的系统控制。

这是通过把不想要的控制输出置零取得。

在控制系统中存在P,PI,PD,PID调节器。

PI调节器很普遍,因为微分控制对测量噪音非常敏感。

积分作用的缺乏可以防止系统根据控制目标而达到它的目标值。

关键字:PID 最佳控制反馈1.控制环基础一个关于控制环类似的例子就是保持水在理想温度,涉及到两个过程,冷、热水的混合。

人可以凭触觉估测水的温度。

基于此他们设计一个控制行为:用冷水龙头调整过程。

重复这个过程,调节热水流直到温度处于期望的稳定值。

感觉水温就是对过程值或变量的测量。

期望得到的温度称为给定值。

控制器的输出对象和过程的输入对象称为控制参数。

测量值与给定值之间的差就是偏差值,太高、太低或正常。

作为一个控制器,在确定温度给定值后,就可以粗略决定改变阀门位置多少,以及怎样改变偏差值。

首次估计即是PID 控制器的比例度的确定。

当它几乎正确时,PID控制器的积分作用就是起着逐渐调整温度的作用。

微分作用就是根据水温变得更热、更冷,以及变化速率来决定什么时候、怎样调整那些阀门。

Inventory managementInventory ControlOn the so-called "inventory control", many people will interpret it as a "storage management", which is actually a big distortion.The traditional narrow view, mainly for warehouse inventory control of materials for inventory, data processing, storage, distribution, etc., through the implementation of anti-corrosion, temperature and humidity control means, to make the custody of the physical inventory to maintain optimum purposes. This is just a form of inventory control, or can be defined as the physical inventory control. How, then, from a broad perspective to understand inventory control? Inventory control should be related to the company's financial and operational objectives, in particular operating cash flow by optimizing the entire demand and supply chain management processes (DSCM), a reasonable set of ERP control strategy, and supported by appropriate information processing tools, tools to achieved in ensuring the timely delivery of the premise, as far as possible to reduce inventory levels, reducing inventory and obsolescence, the risk of devaluation. In this sense, the physical inventory control to achieve financial goals is just a means to control the entire inventory or just a necessary part; from the perspective of organizational functions, physical inventory control, warehouse management is mainly the responsibility of The broad inventory control is the demand and supply chain management, and the whole company's responsibility.Why until now many people's understanding of inventory control, limited physical inventory control? The following two reasons can not be ignored:First, our enterprises do not attach importance to inventory control. Especially those who benefit relatively good business, as long as there is money on the few people to consider the problem of inventory turnover. Inventory control is simply interpreted as warehouse management, unless the time to spend money, it may have been to see the inventory problem, and see the results are often very simple procurement to buy more, or did not do warehouse departments .Second, ERP misleading. Invoicing software is simple audacity to call it ERP, companies on their so-called ERP can reduce the number of inventory, inventory control, seems to rely on their small software can get. Even as SAP, BAAN ERP world, the field ofthese big boys, but also their simple modules inside the warehouse management functionality is defined as "inventory management" or "inventory control."

In other words, inventory itself is across the entire demand and supply management processes in all aspects of inventory control in order to achieve the fundamental purpose, it must control all aspects of inventory, rather than just manage the physical inventory at hand.Third, inventory control, organizational structure and assessment.Since inventory control is the demand and supply chain management processes, output, inventory control to achieve the fundamental purpose of this process must be compatible with a rational organizational structure.

Sampling is not used only in audit – is used in sampling surveys,market analysis and medical research in which someone wants to reach aconclusion about a large number of data by examining only a part of thesedata. The difference is the “population” from which the sample is selected, iethat set of data which is intended to draw a conclusion. Audit sampling appliesonly to certain types of audit procedures.Key words: sampling, sample risk, population, sampling unit, tests ofcontrols, substantive procedures.Statistical samplingCommittee statistical sampling of American Institute of CertifiedPublic Accountants of (AICPA) issued in 1962 a special report, titled“Statistical sampling and independent auditors’ which allowed the use ofstatistical sampling method, in accordance with Generally Accepted AuditingStandards (GAAS). During 1962-1974, the AICPA published a series of paperson statistical sampling, “Auditor’s Approach to Statistical Sampling”, foruse in continuing professional education of accountants. During 1962-1974,the AICPA published a series of papers on statistical sampling, “Auditor’sApproach to Statistical Sampling”, for use in continuing professional educationof accountants. In 1981, AICPA issued the professional standard, “AuditSampling”, which provides general guidelines for both sampling methods,statistical and non-statistical.Earlier audits included checks of all transactions in the period coveredby the audited financial statements. At that time, the literature has not givenparticular attention to this subject. Only in 1971, an audit procedures programprinted in the “Federal Reserve Bulletin (Federal Bulletin Stocks)” includedseveral references to sampling such as selecting the “few items” of inventory.Statistics and Audit The program was developed by a special committee, which later became the AICPA, that of Certified Public Accountants American Institute.In the first decades of last century, the auditors often applied sampling, but sample size was not in related to the efficiency of internal control of the entity. In 1955, American Institute of Accountants has published a study case of extending the audit sampling, summarizing audit program developed by certified public accountants, to show why sampling is necessary to extend the audit. The study was important because is one of the leading journal on sampling which recognize a relationship of dependency between detail and reliability testing of internal control.In 1964, the AICPA’s Auditing Standards Board has issued a report entitled “The relationship between statistical sampling and Generally Accepted Auditing Standards (GAAS)” which illustrated the relationship between the accuracy and reliability in sampling and provisions of GAAS.In 1978, the AICPA published the work of Donald M. Roberts,“Statistical Auditing”which explains the underlying theory of statistical sampling in auditing.In 1981, AICPA issued the professional standard, named “Audit Sampling”, which provides guidelines for both sampling methods, statistical and non-statistical.An auditor does not rely solely on the results of a single procedure to reach a conclusion on an account balance, class of transactions or operational effectiveness of the controls. Rather, the audit findings are based on combined evidence from several sources, as a consequence of a number of different audit procedures. When an auditor selects a sample of a population, his objective is to obtain a representative sample, ie sample whose characteristics are identical with the population’s characteristics. This means that selected items are identical with those remaining outside the sample.In practice, auditors do not know for sure if a sample is representative, even after completion the test, but they “may increase the probability that a sample is representative by accuracy of activities made related to design, sample selection and evaluation” [1]. Lack of specificity of the sample results may be given by observation errors and sampling errors. Risks to produce these errors can be controlled.Observation error (risk of observation) appears when the audit test did not identify existing deviations in the sample or using an inadequate audit technique or by negligence of the auditor.Sampling error (sampling risk) is an inherent characteristic of the survey, which results from the fact that they tested only a fraction of the total population. Sampling error occurs due to the fact that it is possible for Revista Română de Statistică nr. 5 / 2010Statistics and Auditthe auditor to reach a conclusion, based on a sample that is different from the conclusion which would be reached if the entire population would have been subject to audit procedures identical. Sampling risk can be reduced by adjusting the sample size, depending on the size and population characteristics and using an appropriate method of selection. Increasing sample size will reduce the risk of sampling; a sample of the all population will present a null risk of sampling.Audit Sampling is a method of testing for gather sufficient and appropriate audit evidence, for the purposes of audit. The auditor may decide to apply audit sampling on an account balance or class of transactions. Sampling audit includes audit procedures to less than 100% of the items within an account balance or class of transactions, so all the sample able to be selected. Auditor is required to determine appropriate ways of selecting items for testing. Audit sampling can be used as a statistical approach and a non- statistical.Statistical sampling is a method by which the sample is made so that each unit consists of the total population has an equal probability of being included in the sample, method of sample selection is random, allowed to assess the results based on probability theory and risk quantification of sampling. Choosing the appropriate population make that auditor’ findings can be extended to the entire population.Non-statistical sampling is a method of sampling, when the auditor uses professional judgment to select elements of a sample. Since the purpose of sampling is to draw conclusions about the entire population, the auditor should select a representative sample by choosing sample units which have characteristics typical of that population. Results will not extrapolate the entire population as the sample selected is representative.Audit tests can be applied on the all elements of the population, where is a small population or on an unrepresentative sample, where the auditor knows the particularities of the population to be tested and is able to identify a small number of items of interest to audit. If the sample has not similar characteristics for the elements of the entire population, the errors found in the tested sample can not extrapolate.Decision of statistical or non-statistical approach depends on the auditor’s professional judgment which seeking sufficient appropriate audits evidence on which to completion its findings about the audit opinion.As a statistical sampling method refer to the random selection that any possible combination of elements of the community is equally likely to enter the sample. Simple random sampling is used when stratification was not to audit. Using random selection involves using random numbers generated byRomanian Statistical Review nr. 5 / 2010Statistics and Audit a computer. After selecting a random starting point, the auditor found the first random number that falls within the test document numbers. Only when the approach has the characteristics of statistical sampling, statistical assessments of risk are valid sampling.In another variant of the sampling probability, namely the systematic selection (also called random mechanical) elements naturally succeed in office space or time; the auditor has a preliminary listing of the population and made the decision on sample size. “The auditor calculated a counting step, and selects the sample element method based on step size. Step counting is determined by dividing the volume of the community to sample the number of units desired. Advantages of systematic screening are its usability. In most cases, a systematic sample can be extracted quickly and method automatically arranges numbers in successive series.”[2].Selection by probability proportional to size - is a method which emphasizes those population units’recorded higher values. The sample is constituted so that the probability of selecting any given element of the population is equal to the recorded value of the item;Stratifi ed selection - is a method of emphasis of units with higher values and is registered in the stratification of the population in subpopulations. Stratification provides a complete picture of the auditor, when population (data table to be analyzed) is not homogeneous. In this case, the auditor stratifies a population by dividing them into distinct subpopulations, which have common characteristics, pre-defined. “The objective of stratification is to reduce the variability of elements in each layer and therefore allow a reduction in sample size without a proportionate increase in the risk of sampling.” [3] If population stratification is done properly, the amount of sample size to come layers will be less than the sample size that would be obtained at the same level of risk given sample with a sample extracted from the entire population. Audit results applied to a layer can be designed only on items that are part of that layer.I appreciated as useful some views on non-statistical sampling methods, which implies that guided the selection of the sample selecting each element according to certain criteria determined by the auditor. The method is subjective; because the auditor selects intentionally items containing set features him.The selection of the series is done by selecting multiple elements series (successive). Using sampling the series is recommended only if a reasonable number of sets used. Using just a few series there is a risk that the sample is not representative. This type of sampling can be used in addition to other samples, where there is a high probability of occurrence of errors. At the arbitrary selection, no items are selected preferably from the auditor, Revista Română de Statistică nr. 5 / 2010Statistics and Auditthat regardless of size or source or characteristics. Is not the recommended method, because is not objective.That sampling is based on the auditor’s professional judgment, which may decide which items can be part or not sampled. Because is not a statistical method, it can not calculate the standard error. Although the sample structure can be constructed to reproduce the population, there is no guarantee that the sample is representative. If omitted a feature that would be relevant in a particular situation, the sample is not representative.Sampling applies when the auditor plans to make conclusions about population, based on a selection. The auditor considers the audit program and determines audit procedures which may apply random research. Sampling is used by auditors an internal control systems testing, and substantive testing of operations. The general objectives of tests of control system and operations substantive tests are to verify the application of pre-defined control procedures, and to determine whether operations contain material errors.Control tests are intended to provide evidence of operational efficiency and controls design or operation of a control system to prevent or detect material misstatements in financial statements. Control tests are necessary if the auditor plans to assess control risk for assertions of management.Controls are generally expected to be similarly applied to all transactions covered by the records, regardless of transaction value. Therefore, if the auditor uses sampling, it is not advisable to select only high value transactions. Samples must be chosen so as to be representative population sample.An auditor must be aware that an entity may change a special control during the course of the audit. If the control is replaced by another, which is designed to achieve the same specific objective, the auditor must decide whether to design a sample of all transactions made during or just a sample of transactions controlled again. Appropriate decision depends on the overall objective of the audit test.Verification of internal control system of an entity is intended to provide guidance on the identification of relevant controls and design evaluation tests of controls.Other tests:In testing internal control system and testing operations, audit sample is used to estimate the proportion of elements of a population containing a characteristic or attribute analysis. This proportion is called the frequency of occurrence or percentage of deviation and is equal to the ratio of elements containing attribute specific and total number of population elements. WeightRomanian Statistical Review nr. 5 / 2010Statistics and Audit deviations in a sample are determined to calculate an estimate of the proportion of the total population deviations.Risk associated with sampling - refers to a sample selection which can not be representative of the population tested. In other words, the sample itself may contain material errors or deviations from the line. However, issuing a conclusion based on a sample may be different from the conclusion which would be reached if the entire population would be subject to audit.Types of risk associated with sampling:Controls are more effective than they actually are or that there are not significant errors when they exist - which means an inappropriate audit opinion. Controls are less effective than they actually are that there are significant errors when in fact they are not - this calls for additional activities to establish that initial conclusions were incorrect.Attributes testing - the auditor should be defining the characteristics to test and conditions for misconduct. Attributes testing will make when required objective statistical projections on various characteristics of the population. The auditor may decide to select items from a population based on its knowledge about the entity and its environment control based on risk analysis and the specific characteristics of the population to be tested.Population is the mass of data on which the auditor wishes to generalize the findings obtained on a sample. Population will be defined compliance audit objectives and will be complete and consistent, because results of the sample can be designed only for the population from which the sample was selected.Sampling unit - a unit of sampling may be, for example, an invoice, an entry or a line item. Each sample unit is an element of the population. The auditor will define the sampling unit based on its compliance with the objectives of audit tests.Sample size - to determine the sample size should be considered whether sampling risk is reduced to an acceptable minimum level. Sample size is affected by the risk associated with sampling that the auditor is willing to accept it. The risk that the auditor is willing to accept lower, the sample will be higher.Error - for detailed testing, the auditor should project monetary errors found in the sample population and should take into account the projected error on the specific objective of the audit and other audit areas. The auditor projects the total error on the population to get a broad perspective on the size of the error and comparing it with tolerable error.For detailed testing, tolerable error is tolerable and misrepresentations Revista Română de Statistică nr. 5 / 2010Statistics and Auditwill be a value less than or equal to materiality used by the auditor for the individual classes of transactions or balances audited. If a class of transactions or account balances has been divided into layers error is designed separately for each layer. Design errors and inconsistent errors for each stratum are then combined when considering the possible effect on the total classes of transactions and account balances.Evaluation of sample results - the auditor should evaluate the sample results to determine whether assessing relevant characteristics of the population is confirmed or needs to be revised.When testing controls, an unexpectedly high rate of sample error may lead to an increase in the risk assessment of significant misrepresentation unless it obtained additional audit evidence to support the initial assessment. For control tests, an error is a deviation from the performance of control procedures prescribed. The auditor should obtain evidence about the nature and extent of any significant changes in internal control system, including the staff establishment.If significant changes occur, the auditor should review the understanding of internal control environment and consider testing the controls changed. Alternatively, the auditor may consider performing substantive analytical procedures or tests of details covering the audit period.In some cases, the auditor might not need to wait until the end audit to form a conclusion about the effectiveness of operational control, to support the control risk assessment. In this case, the auditor might decide to modify the planned substantive tests accordingly.If testing details, an unexpectedly large amount of error in a sample may cause the auditor to believe that a class of transactions or account balances is given significantly wrong in the absence of additional audit evidence to show that there are not material misrepresentations.When the best estimate of error is very close to the tolerable error, the auditor recognizes the risk that another sample have different best estimate that could exceed the tolerable error.ConclusionsFollowing analysis of sampling methods conclude that all methods have advantages and disadvantages. But the auditor is important in choosing the sampling method is based on professional judgment and take into account the cost / benefit ratio. Thus, if a sampling method proves to be costly auditor should seek the most efficient method in view of the main and specific objectives of the audit.Romanian Statistical Review nr. 5 / 2010Statistics and Audit The auditor should evaluate the sample results to determine whether the preliminary assessment of relevant characteristics of the population must be confirmed or revised.

从长远来看,可再生能源将是未来人类的主要能源来源,因此世界上多数发达国家和部分发展中国家都十分重视可再生能源对未来能源供应的重要作用。

在新的可再生能源中,光伏发电和风力发电是发展最快的,世界各国都把太阳能光伏发电的商业化开发和利用作为重要的发展方向。

根据欧洲JRC 的预测,到2030年太阳能发电将在世界电力的供应中显现其重要作用,达到10%以上,可再生能源在总能源结构中占到30%;2050 年太阳能发电将占总能耗的20%,可再生能源占到50%以上,到本世纪末太阳能发电将在能源结构中起到主导作用。

我国政府重视可再生能源技术的发展,主要有水能、风能、生物质能、太阳能、地热能和海洋能等。

我国目前可再生能源的发展现状如下:水能:我国经济可开发的水能资源量为3.9 亿千瓦,年发电量1.7 万亿千瓦时,其中5 万千瓦及以下的小水电资源量为1.25 亿千瓦。

建筑施工质量控制外文翻译参考文献

建筑施⼯质量控制外⽂翻译参考⽂献建筑施⼯质量控制外⽂翻译参考⽂献(⽂档含中英⽂对照即英⽂原⽂和中⽂翻译)译⽂:建筑施⼯过程中质量管理的动机分析和控制⽅法的研究摘要在建筑施⼯过程中实施质量管理可以有效地防⽌在后续建筑产品使⽤过程中安全事故的发⽣。

与此同时可以减少建设供应链的总成本,这也有利于增强建筑施⼯企业的品牌知名度和声誉。

在建筑施⼯过程中结合质量管理过程和当前建筑施⼯阶段的主要质量问题,分析了建设过程中的管理动机,将供应链管理与⽬标管理理念和⽅法应⽤到质量管理中,最后提出了具体的质量控制措施。

这些都是为了在建筑施⼯过程中提⾼建筑产品的总体质量。

关键字——建筑施⼯、质量管理、质量动机、控制1.引⾔调查显⽰建筑施⼯企业主要采⽤现场控制的质量管理模式是预先控制。

⼤多企业常常使得建筑施⼯过程中与建设管理中的质量管理相同,他们通常忽略了施⼯准备阶段质量问题的预防,如供应商的选择、道路的规划和临时设施,这些因素在建筑施⼯过程中的质量管理上起着⾄关重要的作⽤。

建设质量事故频繁发⽣,引起了许多领域的⾼度关注,如各级政府部门、施⼯企业和业主,特别是重庆綦江虹桥的坍塌、五龙的滑坡和洪湖湿地路基施⼯中的⼀系列质量安全事故,⼈们开始对施⼯质量问题做全⽅位的思考。

通过研究李秀峰总结归纳了造成⼯程的质量问题并引⼊项⽬质量控制分析⽅法,Low Sui Pheng 和Jasmine Ann Teo[2] 建⽴了施⼯中的质量管理框架来通过经验分析实现项⽬的质量控制,SangHyun Lee and others[3] 利⽤系统质量动态结构和变更管理模型的编程⽅法和控制⽅法,最终实现了⼤规模的并⾏设计和施⼯项⽬的管理和控制。

⽅唐分析了建设项⽬质量管理的整个过程和控制⽅法,她认为应该实现对影响建设单位质量的⼈、材料、机械、⽅法和环境的完全控制;吴天翔研究出管理因素是影响建设项⽬质量控制的重要因素,强调了施⼯过程中需要严格控制的各个⽅⾯和整体实现加强管理的需要。

姚鼐《李斯论》原文及译文

姚鼐《李斯论》原文及译文

姚鼐?李斯论?原文(yuánwén)及翻译姚鼐李斯论〔1〕苏子瞻谓李斯以荀卿(xún qīnɡ)之学乱天下〔2〕,是不然。

秦之乱天下之法,无待于李斯,斯亦未尝以其学事秦。

当秦之中叶,孝公即位〔3〕,得商鞅任之〔4〕。

商鞅教孝公燔?诗?、?书?,明法令〔5〕,设告坐之过〔6〕,而禁游宦之民〔7〕。

因秦国地形便利〔8〕,用其法,富强数世,兼并诸侯,迄至始皇。

始皇之时,一用商鞅成法而已,虽李斯助之,言其便利,益成秦乱,然使李斯不言其便,始皇固自为之而不厌。

何也?秦之甘于(gānyú)刻薄而便于严法久矣,其后世所习以为善者也〔9〕。

斯逆探始皇、二世(èr shì)之心〔10〕,非是缺乏以中侈君张吾之宠〔11〕。

是以尽舍其师荀卿之学,而为商鞅之学;扫去三代先王仁政〔12〕,而一切取自恣肆以为治,焚?诗?、?书?,禁学士〔13〕,灭三代法而尚督责〔14〕,斯非行其学也,趋时而已。

设所遭值非始皇、二世,斯之术将不出于此,非为仁也,亦以趋时而已〔15〕。

君子之仕也,进不隐贤;小人之仕也,无论所学识非也,即有学识甚当,见其君国行事,悖谬无义,疾首颦蹙于私家之居〔16〕,而矜夸导誉于朝庭之上,知其不义而劝为之者,谓天下将谅我之无可奈何于吾君,而不吾罪也;知其将丧国家而为之者,谓当吾身容可以免也〔17〕。

且夫小人虽明知世之将乱,而终不以易目前之富贵,而以富贵之谋,贻天下之乱,固有终身安享荣乐,祸遗后人,而彼宴然无与者矣〔18〕。

嗟乎!秦未亡而斯先被五刑夷三族也,其天之诛恶人(è rén),亦有时而信也邪!?易?曰:“眇能视,跛能履;履虎尾,咥人凶。

〞〔19〕其能视且履者幸也,而卒于凶者,益其自取邪!且夫人有为善而受教于人者矣,未闻为恶而必受教于人者也。

荀卿述先王而颂言儒效〔20〕,虽间有得失,而大体得治世之要。

而苏氏以李斯之害天下罪及于卿,不亦远乎?行其学而害秦者,商鞅也;舍其学而害秦者,李斯也。

《日知录·文须有益于天下》原文及翻译
顾炎武
原文:
文之不可绝于天地者,曰明道也,纪政事也,察民隐也,乐道人之善也。

若此者,有益于天下,有益于将来。

多一篇,多一篇之益矣。

若天怪力乱神之事,无稽之言,剿袭之说,谀佞之文,若此者,有损于己,无益于人,多一篇,多一篇之损矣。

注释:
词类活用:明:形容词作动词,阐明。

善:形容词作名词,善行。

句式特点:
1、绝于天地者:“于天地者绝”,状语后置。

2、文之不可#from 本文来自九象,全国最大的免费范文网 end#绝于天地者:判断句。

3、有益于天下,有益于将来:均是状语后置。

4、有损于己,无益于人:均是状语后置。

翻译:
文章不能在天地之间断绝,是因为它可以阐明道理,记述政事、体察百姓困苦、乐于称道别人的善行啊。

像这样,有益于天下,有益于将来。

多一篇,就多一篇的好处啊。

如果涉及那些怪异、斗恨、悖乱、鬼神之事,写无从考察的话,抄袭别人的观点,作奉承谄媚的文字,像这样,对自己有害,对别人无益,多一篇,就多一篇的损害啊。

《旧唐书·高适传》原文及译文《旧唐书·高适传》原文及翻译原文:高适者,渤海蓚人也。

少家贫,客于梁、宋,以求丐自给。

其性傲于权贵,窥察洞明。

及冠始留意诗什,以气质自高,每吟一篇,喜为好诗者称诵。

宋州刺史张九皋深奇之,荐举有道科。

时右相李林甫擅权,薄于文雅,唯以举子待之,适拂袖而去,客游河右。

河西节度哥舒翰见而异之,表为左骁卫兵曹,充翰府掌书记,从翰入朝,盛称之于上前,已而又去。

会禄山之乱,征于翰讨禄山,拜适左拾遗兼监察御史,仍佐翰守南阳。

及翰兵败,适自骆谷西驰,谒见玄宗,因陈败亡之势曰:“监军李大宜不恤军卒,食仓米饭且犹不足,欲其勇战,安可得乎?且南阳之帅各皆持节,宁有是,战而能必拔哉?陛下因此西幸蜀中,避其虿毒,未足为耻也。

”玄宗深纳之,后禄山兵恙果弗及,玄宗嘉之,寻迁侍御史。

镏荨二年,永王璘起兵于江东,欲据扬州。

初,上皇以诸王分镇,适切谏不可。

及是永王叛,肃宗闻其论谏有素,召而谋之。

适因陈江东利害,永王必败。

上奇其对,以适兼御史大夫、扬州大都督府长史、淮南节度使平江淮之乱。

兵罢,宰相李辅国恶适敢言,短于上前,乃左授太子少詹事。

未几,蜀中乱,出为蜀州刺史,剑南自玄宗还京后,于梓、益二州各置一节度,吏制繁冗,百姓劳敝,适论之曰:“蜀地位在邈远,垂于险绝,以国家言之,不足以厄其势。

奈何以险阻弹丸之地,而困全蜀太平之人哉?”疏奏不纳。

后梓州副使段子璋反,以兵攻东川节度使李奂,适率州兵从西川节度使崔光远攻于璋,斩之。

玄宗感其洞明,以黄门侍郎严武代之还,用为刑部侍郎,转散骑常侍,加银青光禄大夫,进封渤海县侯,食邑七百户。

适止轻车诣任,食邑皆封还。

永泰元年正月卒,赠礼部尚书,谥曰忠。

(旧唐书·高适传)译文:高适,是渤海郡蓚县人。

小时候家里贫困,客居梁、宋,以乞讨为生。

他性格对权贵十分傲气,观察事物有先见之明。

等到二十岁时才关注诗歌,凭借气质自我欣赏,每吟诵一篇,喜欢被爱好诗歌的人传诵。

时关畿乱离,谷食踊贵,甫寓居成州同谷县,自负薪采梠,儿女饿殍者数人。

久之,召补京兆府功曹。

上元二年冬,黄门侍郎、郑国公严武镇成都,奏为节度参谋、检校尚书工部员外郎,赐绯鱼袋。

武与甫世旧,待遇甚隆。

甫性褊躁,无器度,恃恩放恣。

尝凭醉登武之床,瞪视武曰:“严挺之乃有此儿!”武虽急暴,不以为忤。

甫于成都浣花里种竹植树,结庐枕江,纵酒啸咏,与田畯野老相狎荡,无拘检。

严武过之,有时不冠,其傲诞如此。

永泰元年夏,武卒,甫无所依。

及郭英乂代武镇成都,英乂武人粗暴,无能刺谒,乃游东蜀依高适。

既至而适卒。

是岁,崔宁杀英乂,杨子琳攻西川,蜀中大乱。

甫以其家避乱荆、楚,扁舟下峡,未维舟而江陵乱,乃溯沿湘流,游衡山,寓居耒阳。

桑悦《独坐轩记》原文及译文桑悦《独坐轩记》原文及翻译原文:予为西昌校官,学圃中筑一轩,大如斗,仅容台、椅各一。

台仅可置经、史数卷,宾至无可升降,弗肃以入,因名之曰“独坐”。

予训课暇,辄憩其中,上求尧、舜、禹、汤、文、武、周公、孔子之道,次窥关、闽、濂、洛数君子之心,又次则咀嚼《左传》、荀卿、班固、司马迁、扬雄、刘向、韩、柳、欧、苏、曾、王之文,更暇则取秦、汉以下古人行事之迹,少加褒贬,以定万世之是非,悠哉悠哉,以永终日。

轩前有池半亩,隙地数丈。

池种芰荷,地杂植松、桧、竹、柏。

予坐是轩,尘坌不入,胸次日拓;又若左临太行,右抉东海,而荫万间之广厦也。

且坐惟酬酢千古。

遇圣人,则为弟子之位,若亲闻训诲;遇贤人,则为交游之位,若亲投膝而语;遇乱臣贼子,则为士师之位,若亲降诛罚于前。

坐无常位,接无常人,日觉纷挐纠错。

坐安得独?虽然,予之所纷挐纠错者,皆世之寂寞者也。

我在教课的空闲,就在里边休息,首先学习尧、舜、禹、汤、文、武、周公、孔子的治世之道,其次学习宋代理学的主要学派(关闽濂洛:指宋代理学的主要学派,其代表人物为关中张载,闽中朱熹,濂溪周敦颐,洛阳程颢、程颐)的思想,再次就品味《左传》、荀卿、班固、司马迁、扬雄、刘向、韩愈、柳宗元、欧阳修、苏轼、曾巩、王安石的文章,再有空闲就浏览秦汉以来的古人的事迹,稍加以评论,来论定万世的是非,悠哉悠哉,以此度日。

屋前有半亩水池,几丈的空地,池塘里种了荷花,土地上错杂的种植着松树、桧树、竹子、柏树。

我坐在这屋子里,凡俗的事不想,胸怀更加开阔,又像左边临着太行山,右边临着东海,而遮掩着万间的大房子。

部分参考文献及译文:Datebase Overview【Key Words】:Data Database Field RecordTable Relation Query Information RetrievalA database (sometimes spelled data base) is also called an electronic database, referring to any collection of data, or information, that is specially organized for rapid search and retrieval by a computer. Databases are structured to facilitate the storage, retrieval, modification, and deletion of data in conjunction with various data-processing operations. Databases can be stored on magnetic disk or tape, optical disk, or some other secondary, storage device.A database consists of a file or a set of files. The information in these files may be broken down into records, each of which consists of one or more fields. Fields are the basic units of data storage, and each field typically contains information pertaining to one aspect or attribute of the entity described by the database. Using keywords and various sorting commands, users can rapidly search, rearrange, group, and select the fields in many records to retrieve or create reports on particular aggregates of data.Database records and files must be organized to allow retrieval of the information. Early systems were arranged sequentially (i. e.,alphabetically, numerically, or chronologically); the development of direct-access storage devices made possible random access to data via indexes. Queries are the main way users retrieve database information. Typically, the user provides a string of characters, and the computer searches the database for a corresponding sequence and provides the source materials in which those characters appear.A user can request, for exampleAll records in which the content of the field for a person’s last name is the word Smith.The many users of a large database must be able to manipulate the information within it quickly at any given time. Moreover, large business and other organizations tend to build up many independent files containing related and even overlapping data, and their data-processing activities often require the linking of data from several files. Several different types of database management systems have been developed to support these requirements: flat, hierarchical, network, relational, and object-oriented.In flat database, records are organized according to a simple list of entities; many simple databases for personal computers are flat in structure. The records in hierarchical databases are organized in a treelike structure, with each level of records branching off into a set of smaller categories. Unlike hierarchical database, which provide single links between sets of records at different levels, network database create multiple linkages between sets by placing links, or pointer to one set of records in another;the speed and versatility of network database have led to their wide use in business. Relational database are used where associations among files or records cannot be expressed by links; a simple flat list becomes one table, or “relation”, and multiple relations can be mathematically associated to yield desired information. Object-oriented database store and manipulate more complex data structure, call ”objects”, which are organized into hierarchical classes that may inherit properties from classes higher in the chain; this database structure is the most flexible and adaptable.The information in many databases consists of natural-language texts of documents; number-oriented databases primarily contain information such as statistics tables, financial data, and raw scientific and technical data. Small databases can be maintained on personal-computer systems and may be used by individuals at home. These and larger databases have become increasingly important in business life. Typical commercial applications include airline reservations, production management, medical records in hospitals, and legal records of insurance companies. The largest databases are usually maintained by governmental agencies, business organizations, and universities. These databases may contain texts of such material as abstracts, reports, legal statutes, wire services, newspapers and journals, encyclopaedias, and catalogs of various kinds. Reference databases contain bibliographies or indexes that serve as guides to the location of information in books, periodicals, and other published literature. Thousands of these publicly accessibledatabase now exist, covering topics ranging from law, medicing, and engineering to news and current events, games, classified advertisements, and instructional courses. Professional such as scientists, doctors, lawyers, financial analysts, stockbrokers, and researchers of all types increasingly rely on these databases for quick, selective access to large volumes of information.数据库综述数据库(database有时拼作data base)又称为电子数据库,指专门组织起来的一套数据或信息,其目的时为了便于计算机快速查询及检索。
