Aresearch team led by LI Xin from the Cold & Arid Regions Environmental and Engineering Research Institute under CAS recently called on the authorities to set up an early warning system for the possible floods due to glacial lake outbursts in China’s alpine hinterland. The global climate change is an irresistible trend and a challenge facing today’s world, says Dr. CHE Tao, a member of the team. As reported by the Intergovernmen- tal Panel on Climate Change, the average global tempe…  相似文献

The Yellow Wallpaper was a representative work of feminist literature by Charlotte Perkins Gilman.In the novel,the heroine under great repression gradually awakes to seek self identification and revolt against the patriarchy.Many researchers have conducted studies from perspectives of feminism,image,theme and structure of the novel.This paper aims to employ Lacan’s"mirror stage"theory and"three orders"theory to analyze the story.Through observing the image of the"confined woman"in the"mirror"(the yellow wallpaper),her awareness of"selfhood"is gradually awakened:she lives in the Symbolic Order where the patriarchy has imposed many restrictions on her.Unable to live in such a world,while the Real is also incomprehensible,what she could do is to totally immerse herself in the Imaginary Order.That’s why she is creeping like a child.  相似文献

At long last,after two decades of endeavor,China’s first high energy astrophysics research probe is about to take of f.The 2.5-ton Hard X-ray Modulation Telescope(HXMT),which is set to be sent 550 km above the ground early2017,will be carrying a trio set of detectors to gather X-rays emitted by black holes and neutron stars in the 1-250ke V band,and enable Chinese scientists to explore the distribution and property of these mysterious sources–with their own data,for the first time in history,in the next four years or more.In August,BCAS reporter XIN Ling had the privilege to meet astrophysicist ZHANG Shuangnan of the Institute of High Energy Physics(IHEP),Chinese Academy of Sciences who is now principal investigator of the HXMT project.During the interview,ZHANG talked about the telescope’s research missions,potential challenges in orbit,as well as its history and lessons to be learned in developing one of the nation’s first science satellites.  相似文献

AYangtze finless porpoise was born on July 5 at the CAS Institute of Hydro- biology (IHB) in Wuhan, capital of central China’s Hubei Province. This is the world’s first successful breeding of such an animal in an artificial environment. The feat will contribute to the ex situ conserva- tion of this endangered species. Th e fi n l es s p or p o i s e (Neophocaena phocaenoides) is one of the smallest cetaceans in the world. They have three distinct subspecies, and the Yangtze finless po…  相似文献

This essay is intended to explore some of the elements which bring about the tragic destiny of the heroine, Eustacia. She is a beautiful and romantic woman with violent passions. In her dark beauty, Hardy has painted one of his most memorable portraits. This essay attempts to deal with the topic question primarily from two aspects, the inner world of Eustacia herself and the external world around her. In Hardy＇ s work, human existence is usually depicted as a tragedy determined by powers beyond the individual＇ s command the external pressures of society and the internal compulsions of character.  相似文献

<正>China’s ambition to build a 12 m aperture optical/infrared telescope in Tibet has been recently challenged by intense disputes over its design options.The Large Optical/Infrared Telescope,or LOT,which will become the world’s biggest upon completion before the 30 m-level ones are in place,is expected to give Chinese astronomers a head start in exploring the early universe and exoplanets among other scientific goals.However,optical engineers and scientists are holding on to very different opinions as for what is the best technical route to get there.  相似文献

Negative area compressibility(NAC) is a counterintuitive ’squeeze-expand’ behavior in solids that is very rare but attractive due to possible pressure-response applications and coupling with rich physicochemical properties.Herein,NAC behavior is reported in palladium diselenide with a large magnitude and wide pressure range.We discover that,apart from the rigid flattening of layers that has been generally recognized,the unexpected giant NAC effect in PdSe2 largely comes from anomalous...  相似文献
