Neutrino Oscillation Experiments Hopeful to Accelerate the Delivery of Solutions to the “Mystery of Missing Antimatter”

<正>1.Neutrino research occupies an important position in particle physics In 1930,Austrian physicist Pauli[1]proposed the neutrino hypothesis to explain the loss of energy in the process of beta decay.But since neutrinos are uncharged and nearly massless(less than one millionth of the electron mass)and rarely interact with other matter(interact via only the weak force and gravity),they are very diffi cult to detect.For that reason,for a long time,neutrinos only appeared in the equations of theoretical physicists and experiments had failed to confirm their existence.In 1934,Italian physicist Fermi proposed the theory of beta decay that incorporates the neutrino,which was quantitatively consistent with experimental data.In 1941,Chinese physicist WANG     

拓扑绝缘体／超导体界面的研究突破

Majorana费米子是1937年Ettore Majorana提出的,它与电子、正电子完全不同．它的反粒子就是它本身。半个多世纪后的今天,寻找神秘的Majorana费米子仍然是现代物理的研究热点。高能物理学家正试图证明中微子（neutrino）是Majorana费米子。     

The Daya Bay Reactor Neutrino Experiment

Scientific Background On Aug.15, 2011, a new large-scale scientific facility in China, Daya Bay Reactor Neutrino Experiment, started to operate. It is located in Daya Bay Nuclear Power Plant in Guangdong Province, around 50km to both Hong Kong and Shenzhen City. The main scientific goal is to precisely determine the neutrino mixing angle θ13 by detecting neutrinos from the reactors at different distances.

树木的拍摄

树木与人类息息相关,不论自觉或不自觉。人们都意识到,这个世界用于呼吸的空气,环境地球的大气,以及培植未来生物的土壤,全都依赖于树木的存在。人们应该利用摄影去表现春．夏、秋、冬四季树木的形态,表达树木的个性,抒发对大自然热爱的情感,通过摄影活动唤起人们保护自然的意识。     

基于技术引进、消化吸收的自主创新困境及消解对策

实现技术、经济的持续发展必须重视技术引进后的消化和吸收再创新.国家对于技术引进应有明确的战略目标,必须形成一套机制,有效地对国内企业实现激励、导向和制约的作用,促进企业技术引进后能够消化吸收进行自主创新.必须坚持制度创新,建立现代企业制度,使企业真正成为技术引进的主体、技术创新的主体.企业在引进技术时必须注重技术引进的先进性及本土化,技术引进后必须加大研发投入量并最终形成拥有自主知识产权的核心专利技术.     

浅谈生态建筑设计重点及重要性

如今生活在都市里的人都渴望回归自然,希望更多地与大自然接触,但住宅建筑仅有绿色还不能说其具有生态性,住宅的生态型是以绿色为基础涵盖生态环保,可持续发展等多种理念。首先就绿色本身而言,要达到国家有关标准,并具有完整的包括设计,施工,物业管理等多个环节的生命周期评价,且要和所有城市的整体环境质量相结合。其次是垃圾处理,污冰处理的就地化,实现生态最统内部有秩序的循环转换。垃圾就地处理及时,避免了在清运中的撒泄现象和因垃圾堆放而造成的污染。     

蚂蚁的"知音"——记美国生物学家爱德华·威尔逊

如果人类消失,地球上将欣欣向荣;如果蚂蚁消失,成千上万的生物将会跟着消失。20世纪初,著名的英国物理学家卢瑟福曾经骄傲地宣称:科学除了物理之外就是集邮。他的话语中显露出对科学中的博物学传统的轻蔑和不屑一顾。进入20世纪之后,各门科学的研究内容都越来越细致,从前那种"集邮"式的博物学者已经少之又少。但是,总有那么一些不合群的人,偏偏就喜欢研究那些别人不屑一顾的东西,当今的美国生物学家爱德华?威尔逊就是其中之一,他对一种小东西情有独钟。
