Scientists have known for decades that having measles (麻疹）suppresses kid"s immune systems for several weeks or months, leaving them ill-equipped to fight off pneumonia, bronchitis and other infections.Now a team of researchers has suggested that the measles vims may also leave a longer-lasting sort of “immune-amnesia” that makes it harder for people to stave off other illnesses for two years or more.That re-emphasizes the importance of vaccination (疫苗)，said biologist Michael Mina, lead author of a paper that was published in the journal Science.“There may be a long-lasting impact that you can"t undo if your child gets measles,M he said. “I hope this stu% can impress upon people the danger measles poses.”The rearchers used what Mina called “an unconventional approach" to search for the long-lasting immune system effects. Previous work in monkeys suggested that monkeys with the disease lost white blood cells their bodies had trained to fight off other illnes^s, leaving them more likely to be infected.To test if a similar thing may occur in humans, the group mined historical data to find out the relationship between measles incidence (发病率)and deaths from other infectious diseases.and deaths from infectious disease both before and after the introduction of the measles vaccine in the U.K. in the 1960s，Mina and the team saw a sort of shadow effect, where deaths from a variety of non-measles infectious diseases closely tracked measles incidence. The more measles in a population, the more deaths from other illnesses in the 28-month period that followed.“Really it didn"t matter what age gj*oup, what decade or what country, said Mina. “They all showed consistent results ... what we"re suggesting happens over the long term is that your immune system works fine，but it has forgotten what it previously learned.”Some researchers who were not involved in the work questioned whether the reductions in deaths as measles cases declined may have had more to do with improving nutrition and smaller family size than with prolonged immune suppression.Others thought the paper"s opinion of years-long suppression was seemingly reasonable but said they could not comment on the mathematical models the group used.To know for certain what was behind the effect the group saw, Mina agreed, scientists would need to look at immune cells and observe their behavior. He said he would like to push the work in a more traditional direction: back into the laboratory.

小题1:B小题2:A小题3:C小题4:C试题分析：本文叙述了科学家的一种想象，在地球的上方放一面60英里宽的镜子，它可以用来为城市延长照明的时间，它的能量可以融化霜冻，以防霜冻冻坏庄稼。还可以融化冰山，能够改变云的运动以便在需要雨的地方降雨。小题1:细节理解题。根据Itmightbesixtymileswide.故选B。小题2:细节理解题。根据Itwouldbeusedtocatchtherays(光线)ofthesun.Itwoulddirectthesun"sraysupontheearthasachildmightdotomakesunlightdanceonthewallwithahandmirror.镜子能反射阳光，故选A。小题3:细节理解题。根据Theycouldlightupcitiesbynight.故选C。小题4:细节理解题。根据Scientistswouldliketoplaceahugemirrorinspaceabovetheearth.Itmightbesixtymileswide.这是科学家的想象出来的，故选C。点评：细节题为阅读考题的重头戏，所占比例高达80%，相对而言较简单，因为这类题虽然要求理解准确，但基本上限于字面意义的理解，范围也限于局部，因此是我们可望得高分的部分。细节题绝大部分体现“中心思想是解”这一原理。本文都是细节理解题，在文中比较容易找到答案。

小题1:C小题2:B小题3:C小题4:A 试题分析：文章是一篇说明文，说明全世界不同地区的人，有不同的饮食习惯，不论怎样，最重要存在两大问题，一是消除饥饿，二是吃出健康。小题1:推理判断题。由文章第一段科学家列出的每天应吃的食物种类，包括蔬菜、水果、谷物，鱼肉蛋、奶、坚果，要均衡饮食，可推断出C答案中包含的种类多，所以选C。小题2:细节理解题。由此句It doesn"t matter whether food is eaten raw or cooked,“食物是生吃还是熟吃都没关系。”可知raw和cooked应该是对应词，cooked在此的意思是，做熟了的，所以raw是“生的”。故选B。小题3:细节理解题。由第二段最后一句话The important thing is what you eat every day.“最重要的事情是你每天吃什么。” 可知选C。小题4:主旨大意题。由第二段第四行It doesn"t matter whether food is eaten raw or cooked, cool or hot.，推出B不正确；由最后一段第二句话The first is to find some ways to feed the world"s population so that no one in hungry.可知C不对，再根据全文的中心意思，故选A。

For years scientists have been worried about the effects of air pollution on the earth"s natural conditions. Some believe the air inside many houses may be more dangerous than the air outside. It may be one hundred times worse.Indoor air pollution can cause a person to feel tired, to suffer eye pain, headache and other problems. Some pollutants（污染物）can cause breathing disorders, diseases of blood and even cancer. Most scientists agree that every modern house has some kind of indoor pollution.People have paid more attention to the problem now. It is true that when builders began making houses and offices they did not waste energy. To do this they build buildings that limited the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to let out harmful gases.As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building—green plants. Scientists do not really know how plants control air pollution. They believe that a plant"s leaves absorb or take in the pollutants. In exchange the plant lets out oxygen through its leaves and tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and more healthy place.多年来科学家们一直担心的影响,空气污染对地球的自然条件。一些人认为许多房屋内空气比外面的空气可能更危险。这可能更糟一百倍。室内空气污染会使人感到疲劳,出现眼痛、头痛和其他问题。一些污染物(污染物)可导致呼吸疾病、血液疾病,甚至癌症。大多数科学家一致认为每个现代的房子都有某种形式的室内污染。现在人们更加关注的问题。的确,当建筑工人开始房屋和办公室他们不浪费能源。为此他们建造建筑物,有限的内部和外部之间的空气流动。他们也开始使用的人造建筑材料。这些材料目前已知放出有害气体。问题变得更加严重,科学家们开始寻找一种方式来解决它。他们发现了一个天然绿色建筑工厂的污染控制系统。科学家不知道植物如何控制空气污染。他们认为,植物的叶子吸收或污染物。在交换植物让氧气通过它的叶子和小组织在其根源。科学家建议,所有的建筑都应该有一个大的植物或一些小植物内每9平方米的空间。不同的植物的研究显示,每吸收不同的化学物质。所以清洁空气的最有效的方法是使用不同类型的植物。有绿色植物在你的房子可以使它成为一个更漂亮,更健康的地方。

Scientists recently discovered that pictures on cave walls at Creswell Crags are the oldest known in Great Britain. But they didn"t find out in the usual way.Archaeologists often date cave art with a process called radiocarbon dating. The technique can measure the age of carbon found in charcoal（木炭）drawings or painted pictures. Carbon is an element found in many things, including charcoal and even people. But in this case, there was no paint or charcoal to test. People carved the pictures of animals and figures into the rock using stone tools. The scientists had an “aha!” moment when they noticed small rocks stuck to the top of the drawings. The small rocks must have formed after the drawings were made.“It is rare to be able to scientifically date rock art,” said Alistair Pike, an archaeological scientist at Britain"s University of Bristol. “We were very fortunate that some of the engravings were covered by stalagmites（石笋）.When a test proved that the stalagmites formed 12,800 years ago, the scientists knew the art underneath them had to be at least that old. And some of the animals shown, like the European bison, are now extinct--another tip-off that the art is quite old.The artists came to Creswell Crags, This place is one of the farthest points north reached by our ancient ancestors during the Ice Age. At that time, much of the North Sea was dry, so people could move about more easily.Some tools and bones found there are 13,000 to 15,000 years old. They show that the travelers hunted horses, reindeer, and arctic hare. Their artwork is similar to art in France and Germany. It tells scientists that the Creswell Crags artists must have had a close connection to peoples several thousand kilometers away－another important clue to understanding how humans spread out across the world.62. Which of the following can be used as the best title of the passage?A. Cave Art About Animals Is Most BeautifulB. Cave Art Found in an Unusual WayC. Cave Art Turns Out to Be Britain"s OldestD. Cave Art in Britain63. The underlined word “archaeologists” in this passage probably means people ________.A. who study things left behind by people in the pastB. who have rich experience in paintingC. who are interested in wild animalsD. who are good at using stone tools64. Why do scientists say the art is quite old?A. The art was carved into stone with stone tools.B. The animals carved in the stone are beautiful.C. The cave is one of the farthest point in the world.D. Some pictures were covered by stalagmites more than 10,000 years old.65. By studying the cave art, scientists know something about _________.A. how ancient people crossed the North SeaB. why some of the animals have died outC. how humans spread out across the worldD. what kind of animals people hunt at that time答案 CAD

It is reported that the activity will last a week. The purpose of this activity is mainly through the expert panel and a series of experience activities to let the youth feel the charming of science. In the spot, the scientists share the knowledge of astronomy in an easy way and the youth asking questions actively. After the activity, the youth said that this activity is very meaningful and widen their vision. The activity also inspire them to study harder in order to bee a scientist in the future. Besides, they said that the informative activity also support them a meaningful holiday. 　　科学家英语作文篇2 　　There is a scale in the picture with some nature factors on it"s left tray and some nurture factors on it"s right tray. And in the top of the picture, “The making of a successful scientist—nature or nurture?” reads 　　We can infer from that what counts more to make a successful scientist is nature but not nurture. 　　As we all know, interest leads to success. So, I think if a scientist is successful in one field, he or she must be much more interested in the field than others. Let"s take Einstein for example, if he were not so interested in physics, he would not have been so successful in its field. Thus, we can say the making of a successful scientist is nature. 　　However, the only nature is not enough, the nurture is also absolutely necessary. First, you must be in favor of the field, next, you must learn the knowledge connected with it, only in this way can you keep in up with the scientists who are researching in it and transcend them. During the course, you must learn from others, and so on. Finally you are likely to be a scientist. Imagine it, someone is very very interested in math, but he even doesn"t know what we can get if we add 1 to 1. Do you really think he can be a scientist, a successful scientist? 　　In a word, to make a successful scientist, nature and nurture are both important. 　　科学家英语作文篇3 　　It is generally agreed that society benefits from the work of its members. pare the contributions of artists to society with the 　　contributions of scientists to society. Which type of contribution do you think is valued more by your society? Give specific reasons to support your answer. 　　Artists and scientists both make valuable contributions to our society. It may seem sometimes that artists are more valued. That"s because those artists who are famous make a lot of money. However, they are relatively few. The fact is that scientists are more valued. They get more respect from society for the work they do. 　　Artists reflect their times and their culture. A painter or a writer shows us in pictures and words what we"re like as a people. They record our culture for future generations. Actors and other performers, like singers and dancers, entertain us. They take our minds off our troubles, and 　　remind us how beautiful and exciting our imaginations can be. Artists also help keep their societies mentally and emotionally healthy. For example, children that participate in the arts, such as painting or music, in school do 　　better in their other studies. Art of all types is necessary to the human spirit. 　　The contributions scientists make to society are more obvious. They include the cars we drive, the puters we use at home and at work, and the appliances that help us cook our meals and clean our houses. All of these e from the ideas and hard work of scientists. Because of scientific discoveries, we"re living longer and more healthful lives. 　　Scientists also contribute to the arts. Movies are the result of science. So are television, radio, and the recording of music on CDs. 　　Generally, scientists don"t make as much money as famous artists like film stars, opera singers or successful painters. However, our society gives them more respect, and they generally make a good living. 　　Scientists are considered to be serious professionals, while artists are sometimes viewed as flaky, irresponsible people. So overall, I"d have to conclude that we value scientists more. 》》》》下一页更多精彩“科学家英语写作范文”

Researchers at the University of California found that exposure to the cold increases levels of a protein that helps form brown fat—the type of fat that produces heat and keeps us warm. Brown fat burns energy, ___42____helps us lose weight. White fat stores extra energy, which results___43___weight gain. The researchers said that because air conditioning and heating give us constant,___44_____(comfort) temperatures, our body"s need for brown fat has decreased. They found that: "Outdoor workers in northern Finland who ___45____(expose) to cold temperature have ____46___ significant amount of brown fat when ___47___(compare) to same-aged indoor workers."The research was conducted on two different control groups of mice. ____48_____ group was injected with the protein that helps create brown fat. This group later gained 30% less weight after both groups were fed high-fat diets. The researchers say this could be good news in the fight against obesity（肥胖症）. People who are obese have ＿49＿＿(low) levels of brown fat than thinner people.

Scientistsqualitytobecome an outstandingscientisthas quality,must first beto be curious,for the naturalcuriosity,curiosityfor thegeneral.According to thescientistsIknow,theyare very curiousforeverything.Theywant to know aboutthe law of things,they haveto see thingsis the most essentialone"s ability.As scientists,they canput thingsintothe most basicsimple but very importantrule,and through thesebasicrules toknow manyother things.They understandthingsis not just alist,orto the individualcognition,but theunderstanding oftheirinductionhas become a commonunderstanding.Theseare qualities thatshould have.In addition,the outstandingscientistsmusthave perseverance.Their effortsin the studyprocess,work hard,keep on carving.In addition,the outstandingscientistsgenerally havea strong self-confidence,believe that their own judgments.Self confidence is a kind ofvery important qualities.高二英语水平：What is the most important quality scientists? Some people immediately think of intelligence, IQ, to a class of things, because to reveal the mysteries of nature, to capture the fortress of science, near the sea to catch turtle, shoot for the moon...... Must, have great magic power, prowess, if there is no clever mind, not keen powers of observation, a quality of the imagination, butdon"t forget the memory, and no outstanding imagination and rigorous reasoning ability, is absolutely out of the question. To be aware of, this point of view, this argumentalthough mainly from non scientific workers, but in societyhas a great market. So, what actually is? Let us listen toscientists their sound.The Belgian cell biologists, biochemists Dedive (C.deDuve) said: "usually the scientists described asknowledgeable people, this idea is a grain of truth. In order to do scientific research, at least you have to accept a science training...... We need to learn moreknowledge, accept more exercise....... But, "know everything" is not sufficient to be considered as artcollectors conditions -- scientists is not necessarily artist.The true measure of scientists, is to see whether it cangenerate new knowledge, or more precisely, to see whether it has engaged in scientific needsunderstanding." Please note: this "will", "whether" is crucial, because then he also said: "most of us lack ofinsight into the mysteries of the universe"s extraordinarytalent, but just do not only do what little one can to helpscience building work...... In this case, a person is engaged in science or a scientist is mainly driven by curiosity. When you face the fact, the phenomenon ofstrange, always be overcome by one"s feelings to explor it." Actually, Dedive hinted that everyone, curiosity uorperhaps solve "will", "whether" key, because there is noscientific curiosity, the extraordinary wisdom and understanding may be lost.Bardeen is a famous physicist two times won the Nobel Prize, people called him a remarkable talent of many ages. He gave the impression that the people around,have a curiosity about the physics problems as childrenthings of interest, it is the curiosity that he is full of passion. Bardeen likes physics and math very much, andsoon learn to focus on the problem, and hard work are often brought him great spiritual return. So, curiositybrings passion was the cause of his miracles. In view of this, Gopnik (Alison Gopnik), the scientists compared to the growing of children, Gardiner (Howard Gardner) thenecessary for creative work attachment with the childcuriosity about the outside world around together.Moreover, such a point of view we Einstein in the autobiography also can see.Admittedly, intelligent, IQ intelligence factor plays an important role in scientific research. However, if the stressover the head, as if also does not accord with the facts,because many famous scientists in the history, not onlywhen reading performance is not outstanding, but at the time of the scientific research consciousness to some oftheir own lack of. In "Memoirs of Darwin" one book, weread as follows: "memories of him in a clear and conciseexpression of their ideas, I still as usual, very difficult; thedifficult to me a lot of time consumption; but in this regard will have a compensation benefits, it is: I have to thinklong and intently to every sentence, so I can be ininference, as well as in their own and other people"sobservations, and find out the mistakes and oversights.""I have no understanding of extremely sharp, not very witty: a few intelligent people, such as Huxley, has thegood quality. Therefore, I am just a clumsy critic: I firstread an article or a book, usually to praise...... I follow alengthy abstract thinking route -- this ability, there is a limit to me; therefore, I am in metaphysics and mathematics did not get any achievement. My memory,extensive range, but vague...... My memory is in some ways a poor: any date, or a sentence, in a few days, will be forgotten by me."So, what is the most important qualities of scientists? To sum up, shall not IQ, EQ, is unlikely to be theperseverance, courage, the pursuit of a kind of quality.The only way out, is also looking for. In the variousqualities of human one one excluded, in recent years is quite considerable in scientists interviewed two words in the report: "curiosity" and "interest" has attracted myattention. The butcher looked for his knife and it was in his mouth. Mr. Bian Yulin in a popular science article in paragraph confirmed and strengthened the author:Gamow, science is the source of human pursuit fornature and own understanding. Scientists the most important quality is the most common curiosity. Gamow wrote: "some people say: "curiosity can kill a cat", but I say: "curiosity creates a scientist.""These words have two non identical not. The first relates to what is curiosity; second points that curiosity very ordinary, but it can make a scientist. To get to the bottom of this two points and reach a consensus, not only toanswer "what is the most important quality?" Problems,but also of great significance. What is the curiosity? Whyare scientists the most important quality? Length of be confined to, the following simple reasoning to prove this assertion: embarked on the road of scientific researchpeople, curiosity will interest; interest will be good thinking; good thinking will be found, that can create theinvention. The interlocking logic chain is a true portrayal of scientific research activities, but in the field of scientific research, and its source -- scientists curious, as the most important quality is tenable. It not only for the numerousscientific facts have proved repeatedly, but did produce agreat scientist.

The appearance of El Nino is known to affect the weather around the world. Scientists still do not completely understand it. Yet they now find they can use it to tell about the future in different areas of the world. 　　One example is the work of two scientists at Columbia University in New York, Mark Cane and Gordon Eshel. A scientist of Zimbabwe, Roger Buckland worked with them. They have found that when El Nino appears, Zimbabwe has little or no rain. This means corn crops in Zimbabwe are poor. The last El Nino was in 1991 to 1993.That was when southeastern Africa suffered a serious lack of rain. 　　The scientists wrote about their recent work in the publication Nature. Their computer program can tell when an El Nino will develop up to a year before it does. They suggest that this could provide an effective early warning system for southern Africa, and could prevent many people from starving. 　　1.El Nino is known as ______ . 　　A.the changing of the weather in southern Africa 　　B.the warming of waters in the Pacific Ocean 　　C.the weather which brings drought(旱灾)to Africa 　　D.the weather phenomenon(现象)that brings heavy rains to Africa 2.Scientists study El Nino in order that ______ . 　　A.they can provide a kind of early warning to the place that will suffer from drought B.they can tell why Zimbabwe has little or no rain C.they can do some research work in this field. 　　D.they can put all this information into their computers. 3.Which of the following is true according to the article?

【答案】：when dreaming occurswhen dreaming occurs 解析：参见原文中第三段第二句。

1、计算机的基本原理分为两个部分，分别是存储程序以及程序控制，在使用之前必须要把控制计算机如何进行操作的指令序列和原始数据通过输入设备输送到计算机内存中，然后在使用的过程中就会根据这个程序来执行。 2、计算机在运行时，先从内存中取出第一条指令，通过控制器的译码，按指令的要求，从存储器中取出数据进行指定的运算和逻辑操作等加工，然后再按地址把结果送到内存中去。接下来，再取出第二条指令，在控制器的指挥下完成规定操作。依此进行下去。直至遇到停止指令。程序与数据一样存取，按程序编排的顺序，一步一步地取出指令，自动地完成指令规定的操作是计算机最基本的工作原理，这一原理最初是由美籍匈牙利数学家冯.诺依曼于1945年提出来的，故称为冯.诺依曼原理，冯诺依曼体系结构计算机的工作原理可以概括为八个字：存储程序、程序控制。

现有的安全防范体系中，包括哪几个层次的标准 新会计准则（以下简称新准则）首次构建了比较完整的有机统一体系。在准则层次上分为三层，第一层次是基本准则，建立了会计概念框架，起纲领性作用；第二层次是具体准则，规范各项业务；第三层次是应用指南，解决操作性问题。 在一个完善的安全防范体系中，( )防范手段是防范体系的基础 ABC 网路准入控制首选盈高，感谢关注! 安全技术防范是由什么相结的安全防范体系 安全技术防范是以安全防范技术为先导，以人力防范为基础，以技术防范和实体防范为手段，所建立的一种具有探测、延迟、反应有序结合的安全防范服务保障体系。它是以预防损失和预防犯罪为目的的一项公安业务和社会公共事业。安全技术防范有两种不同的理解。对于警察执法部门而言，安全技术防范就是利用安全防范技术开展安全防范工作的一项公安业务；而对于社会经济部门来说，安全技术防范就是利用安全防范技术为社会公众提供一种安全服务的产业。既然是一种产业，就要有产品的研制与开发，就要有系统的设计、工程的施工、服务和管理。 安全防范系统包括哪些 广义：技术防范系统，包括视讯监控、红外报警、可视门禁、智慧车闸等；物防系统，包括防盗伞、防爬刺、围墙、单元门、防护栏等；人防系统，包括保安、门卫、物业、群防、门卫制度等；消防系统，包括灭火器、自动喷淋灭火系统、楼层消防水枪、自动烟感报警系统。至少这个多。 我国车辆执行安全防范预警"5t"包括哪几个系统 铁路车辆安全防范预警系统——5T系统： 一是THDS，即：红外线轴温探测智慧跟踪系统，利用热辐射原理，重点探测通过车辆轴承运转热温度，对热轴车辆进行跟踪报警，重点防范热切轴事故。大秦线分布有34个红外线探测站63台红外线轴温配车号智慧跟踪系统。站与站之间基本控制在30公里范围内，并采用一机双探模式实现对轴承温度的检测。 二是TFDS，即：货车故障轨边影象检测系统，利用高速摄像原理，对执行车辆配件等关键部位，实时抓拍，并运用计算机网路技术在列车进站前传送到机检室，由动态检车员进行动态检查。对分析出的安全隐患通知现场检车员妥善处理。 三是TPDS，即：货车执行品质轨边动态监测系统。利用轨道测试平台，对车辆安全指标进行动态检测。主要是监测车轮踏面损伤，货物超载、偏载等安全隐患，实现货车执行安全质量互控。 四是TADS，即：货车滚动轴承故障轨边声学诊断系统。主要运用声学技术及计算机技术，对货车滚动轴承执行噪声进行分析，将安全防范关口前移，及早发现轴承早期故障。 五是TCDS系统，是我国客车仅有的行车安全监控系统,TCDS主要应用车载网路和资料采集技术，实现对车辆部件的技术与安全状态进行监测和故障资讯预报,保障铁路运输安全。 网路安全防范体系有哪些设计原则 根据防范安全攻击的安全需求、需要达到的安全目标、对应安全机制所需的安全服务等因素，参照SSE-CMM("系统安全工程能力成熟模型")和ISO17799(资讯保安管理标准)等国际标准，综合考虑可实施性、可管理性、可扩充套件性、综合完备性、系统均衡性等方面，网路安全防范体系在整体设计过程中应遵循以下9项原则： 1．网路资讯保安的木桶原则 网路资讯保安的木桶原则是指对资讯均衡、全面的进行保护。“木桶的最大容积取决于最短的一块木板”。网路资讯系统是一个复杂的计算机系统，它本身在物理上、操作上和管理上的种种漏洞构成了系统的安全脆弱性，尤其是多使用者网路系统自身的复杂性、资源共享性使单纯的技术保护防不胜防。攻击者使用的“最易渗透原则”，必然在系统中最薄弱的地方进行攻击。因此，充分、全面、完整地对系统的安全漏洞和安全威胁进行分析，评估和检测（包括模拟攻击）是设计资讯安全系统的必要前提条件。安全机制和安全服务设计的首要目的是防止最常用的攻击手段，根本目的是提高整个系统的"安全最低点"的安全效能。 2．网路资讯保安的整体性原则 要求在网路发生被攻击、破坏事件的情况下，必须尽可能地快速恢复网路资讯中心的服务，减少损失。因此，资讯安全系统应该包括安全防护机制、安全检测机制和安全恢复机制。安全防护机制是根据具体系统存在的各种安全威胁采取的相应的防护措施，避免非法攻击的进行。安全检测机制是检测系统的执行情况，及时发现和制止对系统进行的各种攻击。安全恢复机制是在安全防护机制失效的情况下，进行应急处理和尽量、及时地恢复资讯，减少供给的破坏程度。 3．安全性评价与平衡原则 对任何网路，绝对安全难以达到，也不一定是必要的，所以需要建立合理的实用安全性与使用者需求评价与平衡体系。安全体系设计要正确处理需求、风险与代价的关系，做到安全性与可用性相容，做到组织上可执行。评价资讯是否安全，没有绝对的评判标准和衡量指标，只能决定于系统的使用者需求和具体的应用环境，具体取决于系统的规模和范围，系统的性质和资讯的重要程度。 4．标准化与一致性原则 系统是一个庞大的系统工程，其安全体系的设计必须遵循一系列的标准，这样才能确保各个分系统的一致性，使整个系统安全地互联互通、资讯共享。 5．技术与管理相结合原则 安全体系是一个复杂的系统工程，涉及人、技术、操作等要素，单靠技术或单靠管理都不可能实现。因此，必须将各种安全技术与执行管理机制、人员思想教育与技术培训、安全规章制度建设相结合。 6．统筹规划，分步实施原则 由于政策规定、服务需求的不明朗，环境、条件、时间的变化，攻击手段的进步，安全防护不可能一步到位，可在一个比较全面的安全规划下，根据网路的实际需要，先建立基本的安全体系，保证基本的、必须的安全性。随着今后随着网路规模的扩大及应用的增加，网路应用和复杂程度的变化，网路脆弱性也会不断增加，调整或增强安全防护力度，保证整个网路最根本的安全需求。 7．等级性原则 等级性原则是指安全层次和安全级别。良好的资讯安全系统必然是分为不同等级的，包括对资讯保密程度分级，对使用者操作许可权分级，对网路安全程度分级（安全子网和安全区域），对系统实现结构的分级（应用层、网路层、链路层等），从而针对不同级别的安全物件，提供全面、可选的安全演算法和安全体制，以满足网路中不同层次的各种实际需求。 8．动态发展原则 要根据网路安全的变化不断调整安全措施，适应新的网路环境，满足新的网路安全需求。 9．易操作性原则 首先，安全措施需要人为去完成，如果措施过于复杂，对人的要求过高，本身就降低了安全性。其次，措施的采用不能影响系统的正常执行。 计算机的安全防范措施包括哪五种？ 网路访问控制，资料库的备份与恢复，资讯加密技术，反病毒技术，研发并完善高安全的作业系统 Oracle llg的安全体系包括哪几层? 开始--执行--services.msc----- 找到服务：OracleOraDb10g_home1TNSListener 与 OracleServiceORCL（注意其中的ORCL服务名）。 这两个就是oracle启动必须的两个服务（预设为自动启动），启动这两个服务就等于开启oracle了。 金融安全防范不包括 D，根据安全防范的定义，安全防范共有三个手段，即人防（人力防范），物防（物理防范或者实体防范），技防（技术防范）。
