[简答题] 脱泡的基本原理是什么？-我要搜题网

Science and politics are inextricably linked. At a scientific conference on climate change held this week in Copenhagen, four environmental experts announced that sea levels appear to be rising almost twice as rapidly as had been forecast by the United Nations just two years ago. (46)The warning is aimed at politicians who will meet in the same city in December to discuss the same subject and, perhaps, to thrash out an international agreement to counter it.
The reason for the rapid change in the predicted rise in sea levels is a rapid increase in the information available. (47)In 2007, when the Intergovernmental Panel on Climate Change convened by the UN made its prediction that sea levels would rise by between 18cm and 59cm by 2100, a lack of knowledge about how the polar ice caps were behaving was behind much of the uncertainty. Since then they have been closely monitored, and the results are disturbing. Both the Greenland and the Antarctic caps have been

[不定项选择题]共用题干 First Image-recognition Software
1. Dartmouth researchers and their colleagues have created an artificial intelligence software that uses photos to locate documents on the Internet with far greater accuracy than ever before.
2. The new system,which was tested on photos and is now being applied to videos,shows for the first time that a machine learning algorithm（运算法则）for image recognition and retrieval is accurate and efficient enough to improve large-scale document searches online. The system uses pixel（像素）data in images and potentially video-rather than just text-to locate documents. It learns to recognize the pixels associated with a search phrase by studying the results from text-based image search en-gines. The knowledge gleaned（收集）from those results can then be applied to other photos without tags or captions（图片说明）,making for more accurate document search results.
3. "Over the last 30 years,"says Associate Professor Lorenzo Torresani,a co-author of the stud-y,"the Web has evolved from a small collection of mostly text documents to a modern,massive, fast-growing multimedia data set,where nearly every page includes multiple pictures or videos. When a person looks at a Web page, he immediately gets the gist（主旨）of it by looking at the pictures in it.Yet,surprisingly,all existing popular search engines,such as Google or Bing, strip away the information contained in the photos and use exclusively the text of Web pages to perform the document retrieval. Our study is the first to show that modern machine vision systems are accurate and efficient enough to make effective use of the information contained in image pix- els to improve document search."
4. The researchers designed and tested a machine vision system-a type of artificial intelligence that allows computers to learn without being explicitly programmed-that extracts semantic（语义的）information from the pixels of photos in Web pages. This information is used to enrich the description of the HTML page used by search engines for document retrieval.The researchers test-ed their approach using more than 600 search queries（查询）on a database of 50 million Web pages. They selected the text-retrieval search engine with the best performance and modified it to make use of the additional semantic information extracted by their method from the pictures of the Web pages.They found that this produced a 30 percent improvement in precision over the original search engine purely based on text. When performing document retrieval the existing search engines ignore______.
A.using photos
B.description of the HTML page
C.current popular search engines
D.document search
E.information in images
F.machine vision systems

[单项选择]Joyce Carol Oates published her first collection of short stories By The North Gates, in 1962, two years after she had received her Master’s degree from the University of Wisconsin and become an instructor of English at the University of Detroit. Her productivity since then has been prodigious, accumulating in less than two decades to nearly thirty titles, including novels, collections of short stories and verse, plays, and literary criticism. In the meantime, she has continued to teach, moving in 1967 from the University of Detroit to the University of Windsor, in Ontario, and in 1978 to Princeton University. Reviewers have admired her enormous energy, but find a productivity of such magnitude difficult to assess.
In a period characterized by the abandonment of so much of the realistic tradition by authors such as John Barth, Donald Barthelme, and Thomas Pynchon, Joyce Carol Oates has seemed at times determinedly old-fashioned in her insistence on the essentially mimetic quality
A. She has experienced long nonproductive periods in her writing.
B. Her style is imitative of other contemporary authors.
C. She has produced a surprising amount of fiction in a relatively short time.
D. Most of her works are based on personal experience.
