资源描述

1、running here and there: they had just discovered that a prisoner had escaped. At that moment, a large black car with four officers inside it, stopped at the camp gates. The officers got out and the prisoner stood to attention and saluted as they passed. When they had gone, the driver of the car came

2、 towards him. The man obviously wanted to talk. He was rather elderly with grey hair and clear blue eyes. The prisoner felt sorry for him, but there was nothing else he could do. As the man came near, the prisoner knocked him to the ground with a sharp blow. Then, jumping into the car, he drove off

3、as quickly as he could. Lesson82 Monster or fish? 是妖还是鱼?Fishermen and sailors sometimes claim to have seen monsters in the sea. Though people have often laughed at stories told by seamen, it is now known that many of these monsters which have at times been sighted are simply strange fish. Occasional

4、ly, unusual creatures are washed to the shore, but they are rarely caught out at sea. Some time ago, however, a peculiar fish was caught near Madagascar. A small fishing-boat was carried miles out to sea by the powerful fish as it pulled on the line. Realizing that this was no ordinary fish, the fis

5、herman made every effort not to damage it in any way. When it was eventually brought to shore, it was found to be over thirteen feet long. It had a head like a horse, big blue eyes, shining silver skin, and a bright red tail, The fish, which has since been sent to a museum where it is being examined

6、 by a scientist, is called an oarfish. Such creatures have rarely been seen alive by man as they live at a depth of six hundred feet.Lesson83 After the elections 大选之后The former Prime Minister, Mr Wentworth Lane, was defeated in the recent elections. He is now retiring from political life and has gon

7、e abroad. My friend, Crawley, has always been a fanatical opponent of Mr Lanes Radical Progressive Party. After the elections, Crawley went to the former Prime Ministers house. When he asked if Mr Lane lived there, the policeman on duty told him that since his defeat, the ex-Prime Minister had gone

8、abroad. On the following day, Crawley went to the house again. The same policeman was just walking slowly past the entrance, when Crawley asked the same question. Though a little suspicious this time, the policeman gave him the same answer. The day after, Crawley went to the house once more and aske

9、d exactly the same question. This time, the policeman lost his temper. I told you yesterday and the day before yesterday, he shouted, Mr Lane was defeated in the elections. He has retired from political life and gone to live abroad ! I know, answered Crawley, but I love to hear you say it ! Lesson84

10、 On strike 罢工Busmen have decided to go on strike next week. The strike is due to begin on Tuesday. No one knows how long it will last. The busmen have stated that the strike will continue until general agreement is reached about pay and working conditions. Most people believe that the strike will la

11、st for at least a week. Many owners of private cars are going to offer free rides to people on their way to work. This will relieve pressure on the trains to some extent. Meanwhile, a number of university students have volunteered to drive buses while the strike lasts. All the young men are expert d

12、rivers, but before they drive any of the buses, they will have to pass a special test. The students are going to take the test in two days time. Even so, people are going to find it difficult to get to work. But so far, the public has expressed its gratitude to the students in letters to the Press.

13、Only one or two people have objected that the students will drive too fast!Lesson85 Never too old to learn 活到老学到老I have just received a letter from my old school informing me that my former head- master, Mr Regmald Page, will be retiring next week. Pupils of the school, old and new, will be sending

14、him a present to mark the occasion. All those who have contributed towards the gift will sign their names in a large album which will be sent to the headmasters home. We shall all remember Mr Page for his patience and understanding and for the kindly encouragement he gave us when we went so unwillin

15、gly to school. A great many former pupils will be attending a farewell dinner in his honour next Thursday. It is a curious coincidence that the day before his retirement, Mr Page will have been teaching for a total of forty years. After he has retired, he will devote himself to gardening. For him, t

16、his will be an entirely new hobby. But this does not matter, for, as he has often remarked, one is never too old to learn. Lesson86 Out of control 失控As the man tried to swing the speed-boat round, the steering-wheel came away in his hands. He waved desperately to his companion, who had been water-sk

17、iing for the last fifteen minutes. Both men had hardly had time to realize what was happening when they were thrown violent1y into the sea. The speed-boat had struck a buoy, but it continued to move very quickly across the water. Both men had just begun to swim towards the shore. when they noticed w

18、ith dismay that the speed-boat was moving in a circle. It now came straight towards them at tremendous speed. In less than a minute, it roared past them only a few feet away. After it had passed, they swam on as quickly as they could because they knew that the boat would soon return. They had just h

19、ad enough time to swim out of danger when the boat again completed a circle. On this occasion, however, it had slowed down considerably. The petrol had nearly all been used up. Before long, the noise dropped completely and the boat began to drift gently across the water.Lesson87 A perfect alibi 极好的不

20、在犯罪现场的证据At the time the murder was committed, I was travelling on the 8.0 oclock train to London, said the man.Do you always catch such an early train ? asked the inspector.Of course I do, answered the man. I must be at work at 10.0 oclock. My employer will confirm that I was there on time. Would a

21、later train get you to work on time ? asked the inspector. I suppose it would, but I never catch a later train.At what time did you arrive at the station ?At ten to eight. I bought a paper and waited for the train.And you didnt notice anything unusual ? Of course not.I suggest, said the inspector, t

22、hat you are not telling the truth. I suggest that you did not catch the 8.0 oclock train, but that you caught the 8.25 which would still get you to work on time. You see, on the morning of the murder, the 8.0 oclock train did not run at all. It broke down at Ferngreen station and was taken off the l

23、ine.Lesson88 Trapped in a mine 困在矿井里Six men have been trapped in a mine for seventeen hours. If they are not brought to the surface soon they may lose their lives. However, rescue operations are proving difficult. If explosives are used, vibrations will cause the roof of the mine to collapse. Rescue

24、 workers are therefore drilling a hole on the north side of the mine. They intend to bring the men up in a special capsule. If there had not been a hard layer of rock beneath the soil, they would have completed the job in a few hours. As it is, they have been drilling for sixteen hours and they stil

25、l have a long way to go. Meanwhile, a microphone, which was lowered into the mine two hours ago, has enabled the men to keep in touch with the closest relatives. Though they are running out of food and drink, the men are cheerful and confident that they will get out soon. They have been told that re

26、scue operations are progressing smoothly. If they knew how difficult it was to drill through the hard rock, they would lose heart. Lesson89 A slip of the tongue 口误People will do anything to see a free show-even if it is a bad one. When the news got round that a variety show would be presented at our

27、 local cinema by the P. and U. Bird Seed Company, we all rushed to see it. We had to queue for hours to get in and there must have been several hundred people present just be- fore the show began. Unfortunately, the show was one of the dullest we have ever seen. Those who failed to get in need not h

28、ave felt disappointed as many of the artistes who should have appeared did not come. The only funny things we heard that evening came from the advertiser at the beginning of the programme. He was obviously very nervous and for some minutes stood awkwardly before the microphone. As soon as he opened

29、his mouth, everyone burst out laughing. We all know what the poor man should have said, but what he actually said was: This is the Poo and Ee Seed Bird Company. Good ladies, evening and gentlemen !lesson90 Whats for supper ? 晚餐吃什么?Though Brazil is one of the richest countries in the world, much of i

30、t has not yet been developed. It was mainly for this reason that the Brazilian government decided to have a new city built 600 miles north-west of Rio de Janeiro. Designed by the great architect Lucio Costa, the new city, Brasilia, replaced Rio de Janeiro as the capital of Brazif in 1960. Brasilia h

31、as been carefully planned for modern living. Its wide roads, which can take fourteen lanes of traffic, have been keptaway from living areas. Children do not have to cross busy streets to go to school. Housewives can visit-shopping centres on foot, for in these specially designed living areas, cars a

32、re unnecessary. At first, the government had great difficulty in persuading people to leave Rio and to settle in Brasilia. Since 1960, however, the population has been growing all the time. Brasilia has quickly established itself as the capital of the country. The idea to have the capital moved so f

33、ar inland will have a great effect on the future of Brazil.Lesson91 Three men in a basket 三人同篮A pilot noticed a balloon which seemed to be making for a Royal Air Force Station nearby. He informed the station at once, but no one there was able to explain the mystery. The officer in the control tower

34、was very angry when he heard the news, because balloons can be a great danger to aircraft. He said that someone might by spying on the station and the pilot was ordered to keep track of the strange object. The pilot managed to circle the balloon for some time. He could make out three men in a basket

35、 under it and one of便携式拉曼光谱仪市场分析报告(可行性研究报告专用版)拉曼光谱仪是一种快速、简单、可重复、且更重要的是无损伤的定性定量分析仪器,它无需样品准备,样品可直接通过光纤探头或者通过玻璃、石英和光纤测量。对于三聚氰胺,可以使用拉曼光谱仪进行快速定性,可以快速判断三聚氰胺的含量。目前,市场上的拉曼光谱仪大多是便携式拉曼光谱仪,便携式的特点是,携带方便,检测人员可以随身携带,在现场、超市等可以随时抽样检测,不仅可以提高工作效率,还具有实时检测样品的情况。另外,拉曼光谱仪还有一个优点,就是对样品检测无需任何耗材。就是说,购买这台仪器回来,不断地对牛奶样品进行三聚氰胺检测

41、情报网2、原料供应目前,全国共有5个国家级激光技术研究中心,10多个研究机构;有21个省、市生产和销售激光产品,常年有定型产品生产和销售、并形成一定规模的单位有200多家,从业人员2万多人。全国激光市场销售主要为光通信器件、激光加工设备、激光器、激光医疗设备等。目前,全国激光市场销售主要为光通信器件、激光加工设备、激光器、激光医疗设备等。当前,武汉、广州、深圳、长春等地都在建立光电子产业群,这无疑将给国内激光产业创造更大的发展空间。国内激光器及设备生产市场主要分布在广东、湖北、北京、江苏、上海这几个省市。其中以光通讯、激光等产业为主导的“武汉中国光谷”,拥有光电子信息企业300多家,显现出强劲

42、的发展势头。北京、上海以其特殊的地理位置,也推动了激光技术的发展;而在广东,小规模的激光企业增速较快。另外,西部地区的西安、成都,凭借科研院所技术的产业化,也有不少激光企业纭纭而生。作为国内光学老工业基地的长春,尽管从事激光产品研发和生产的企业较多,但由于地区问题,许多企业还没有形成大的规模。3、原料价格及其走势激光器的价格因技术指标、产地、运费、供求关系等多种因素的变化而不同,而且价格相差很大,但是其价格变化的总体趋势是下降的。4、原料市场发展预测4.1 中国激光市场发展方向基于中国目前的激光市场特点,可以说,开发中国的激光市场大有潜力,主要反映在以下几个方面:与大众生活密切相关的产品将会成

43、为主要的收入来源。很大一部分激光产品销售将来自光信息技术和娱乐行业,比如DVD碟机、游戏,低功率激光器在此方面的销售将会有巨额增长。随着制造业,特别是汽车,IC封装等产业的发展,工业用激光系统的需求将会大幅增长,这方面将成为在中国开发光纤激光器市场的关键。医疗激光系统的性能在逐步完善,功能也在逐步增强,激光方案成为某些疾病唯一的治疗方式。在人们生活水平普遍提高的背景下,激光美容市场也将快速增长。4.2 光纤激光器的发展双包层光纤激光器是近年来发展的新技术,是高功率激光器小型化、全固化、集成化发展的一个重要方向和必然趋势,是当前国际上着力开发的新型激光器件。与体积庞大的气体激光器、固体激光器及D

44、PSS相比,它具有全固态,高可靠性,光束质量好、转换效率高,加热源分散、易于实现高功率输出等显著优点。因此,双包层光纤激光器是继灯泵固体激光器、半导体泵浦固体激光器之后的第三代激光器。从应用目标出发,连续工作的光纤激光器能提供的靶面功率密度较低,而脉冲工作的光纤激光器更为有用。双包层激光器虽然具有散热好、体积小、效率高、光束质量好等优点,但目前常规脉冲双包层光纤的激光单脉冲输出能量,仍低于高能的气体或固体激光器。因此,双包层光纤激光器在保持其体积小巧、效率高、冷却散热方便、光束质量好等优点的同时,实现更高能量的激光输出,是今后发展的一个重要方向。目前高功率双包层光纤激光器的研究还处于起步阶段,

45、但由于其具有效率高、尺寸小、重量轻、成本低等优点,非常适合用于激光武器和其他军事应用,在军事国防领域有着非常广泛的应用前景。随着新型双包层光纤激光器技术的发展,高功率光纤激光器是军用激光武器发展中最有潜力的方向。4.3 市场开发策略随着光纤激光技术的迅速发展和成熟,光纤激光器的特点和优势已被人们所认识,市场需求和应用逐年在大幅增加,存在很大的市场机会。国内相关厂商可以参考以下市场开发策略。1)瞄准中国市场这是低投资、低风险获取最大利益的最快途径。随着需求的快速增长,世界主要供应商不可避免地将他们有限的资源集中在北美和欧洲主要市场,从而忽略了中国和亚洲市场。而在中国,目前还没有光纤激光器的生产供

46、应厂家。2)降低成本和增加产品附加值与EDFA相类似,光纤激光技术发展初期专业化程度较低。制造商必须自己开发大多数关键技术,如CD光纤、组合器、光栅和泵源。随着市场的大规模化和透明度越来越高,专业化的公司通过提供特定的元件或模块进入市场。这些公司能发挥他们的特定优势开发激光器的某一模块而不是整个激光器。他们的加入会大幅度的降低市场进入门坎,降低材料成本。随着市场规模的扩展,将最终实现批量化生产。3)寻求技术突破尽管光纤激光器在效率、可靠性、高功率、高亮度和体积方面具有无可置疑的优点,但是它的某些缺点限制了它更广泛的应用。当目前的主要供应商如IPG和SPI在集中发展它的高功率优点时,国内厂商可以

47、考虑扩展光纤激光器的应用,在其他方面寻求突破。二、产品更新周期的特点图表 产品更新周期的特点产品技术更新不断加速1完成新产品升级市场竞争呈现新特点2产品功能更强大3产品升级需要品牌提升的硬支撑4资料来源:中国产业竞争情报网三、可能出现的替代产品图表 便携式拉曼光谱仪替代产品分析资料来源:中国产业竞争情报网四、产品使新用途发展图表 便携式拉曼光谱仪用途分析1无机化合物的分析2有机化合物的分析3表面吸附研究4高聚物拉曼光谱的应用资料来源:中国产业竞争情报网六、产品市场需求发展趋势激光拉曼光谱仪是集光谱学、光学、化学计量学、计算机等技术为一体的高新技术,它的出现带来了一场分析技术的革命。纵观拉曼光谱

48、仪发展的过程,可以预料到未来拉曼光谱仪可能向两个方向发展:一个是发展结构复杂、功能更齐全、智能化程度更高,能够满足更高科研测量要求的大型拉曼光谱仪;另一个是发展便携式小型拉曼光谱仪,以满足实际生产和生活中方便快捷的测量需求。在激光拉曼光谱仪的性能提高方面,智能化程度更高,数据处理功能更强大的软件的开发也是一个重要的方面。随着光、机、电等领域科学技术的进一步发展,激光拉曼光谱仪将会在科学研究和实际生产中扮演越来越重要的角色。在拉曼光谱仪技术研究和发展方面,我国现阶段的水平与发达国家相比还有很大的差距,但对拉曼光谱仪的需求却不断提高。因此,我们应该研制符合我国国情的激光拉曼光谱仪,在保证性能指标的前提下,实现先进技术的国产化。七、产品市场容量预测图表 2009-2012年我国便携式拉曼光谱仪市场容量预测资料来源:中国产业竞争情报网我国便携式拉曼光谱仪市场容量在未来几年将不断增长,预计到2012年将增长到1624台,说明我国对便携式拉曼光谱仪的需求很大,因此对于生产企业来说是一个良好的发展机遇。八、产品国内需求量及与现有生产能
