爱是守护 一场海鸥和鹈鹕之间的较量

<正>海鸥,一种最常见的海鸟,甚至人们一提起海鸟就会很自然地最先想到海鸥。在海边,成群的海鸥欢腾雀跃,它们有的悠然自得地漂浮在水面上,有的自由自在地在低空飞翔,偶尔,还会见到两只海鸥突然如离弦之箭,在空中直矢海面,瞬即又腾空而起,互相奋力地争夺着一条小鱼……     

高原上的生灵们

开车行驶在也许是百年前外国探险家进入青藏高原走过的路,眼前的一切并没有让我感到惊叹不已。一百多年来,青藏高原已经发生了巨大的变化,野牦牛、野驴和羚羊踏出来的道路已经变成了宽敞的公路或者砂石路,抑或是窄小的摩托车道,沿着这样的路我们可以深入到更深更远的无人区,那里曾经是生活在青藏高原的精灵们的家园。     

旅行是良药

<正>假日旅行并非只有狂欢和疲惫,在度假中,做一些有利健康的事也未尝不可。预定一次对你的健康和幸福影响持久的旅行吧,也许是在负海拔的死海里惬意漂浮,或是在清迈的养生中心做一次净化身心的排毒项目,都不失为既修身养性又放松自我的度假方式。"旅行疗法"归来,再看看镜子中的你,可能你也会感到一种重获新生般的惊喜。终日为生活忙碌,困在格子间的你,是否已忘记关照自己的身体和心情?药物治疗,这个向来被认为是所有疾病的灵丹妙药的方案,也许对你目前的状况并不适用,何不尝试一次旅行疗健康生活,离开格子间去旅行吧     

樱桃红了 “大樱桃节暨乡村旅游节”在6月向游人招手

<正>中国樱桃之乡山海关已经连续三年举办大樱桃节了。正值2008北京奥运年,举办之地又是奥运协办城市,因此,今年的樱桃之节格外"红"。一红红在乡土游,第三届大樱桃节又名"乡村旅游节",趣味采摘很益智。     

Knowledge is our Destiny

Abstract

Tracing the development of the human spirit from empiricism to science, the desire to know more about science is discussed and considered to be due to two main springs, curiosity and practical utility. This has led directly to two revolutions, the Industrial Revolution and the Information Revolution. Next, the interaction of science, engineering and technology is proclaimed and 'the virtuous circle' drawn to illustrate this interaction, linked to the funding of its three components. As knowledge is power, those who possess it, the scientists and technologists, have the duty to make the societies in which they live more aware of the powers and limitations of science.     

鸟儿——大自然的精灵

正鸟是大自然的精灵,它们能翱翔天宇,能潜游水中,亦能跳跃枝头,是倏忽之间划过眼前的掠影。鸟是美丽的天使,它们有的嘴部夸张亮丽,有的羽毛华丽美艳,还有的尾部醒目绚烂。鸟是跳动的音符,奏响着生动美妙的旋律,礼赞着生命的珍贵和独特。千姿百态的鸟类,使得大自然充满了无限的生气。一直以来,人们对鸟总有一种最强烈的好奇心和亲近愿望。     

黄之恋

<正>如果问一个人,喜欢什麽颜色,很多人会毫不犹豫地说喜欢绿色。人们可以说出无数个理由让你必须喜欢绿色,可我却偏偏喜欢黄色,因为黄色让我去思考,让我感受到历史,让我感受到人生。     

Gold Chemistry is Different

Abstract

The attractive properties of gold have long been taken for granted without any questioning of the basic chemistry that lies behind them. Today, chemists are beginning to find the reasons for gold's unique position among the family of elements. After a general introduction to gold chemicals and a review of some of the element's unusual facets, the author, who has contributed much himself to this research, explains that only through a consideration of relativistic effects has a deeper understanding of the chemistry of gold emerged. These theoretical advances have led to the preparation of a multitude of novel gold compounds characterised by clusters of gold atoms which can incorporate carbon and nitrogen atoms. In the light of these modern concepts of bonding and structure, the chemistry of gold is now a subject of research in many laboratories and its literature has exploded.

湿地,我们的未来

<正>大自然因成千上万的物种共生共栖而充满魅力,在这样一个生命的链条上,我们所有人的命运都紧密相连。我们在细数世界和国内风景名胜区时,会惊讶地发现大多数是湿地类型。比如:大堡礁、普吉岛、黄果树大瀑布、桂林山水、青海湖、洞庭湖等等。似乎自从人类有了审美的那一刻起,湿地就进入了我们的视野。究其原因,是水与生命的关系太密切了,它成为内心潜     

Finance is History!

A new sensitivity to the significance of historical experience has developed since the 2007 financial crisis. There are three possible ways of drawing on the past: as a source of advice on policies, of patterns of past evolution, of multiple possibilities. The best way of thinking about history is as a way of testing conventional hypotheses – particularly when those hypotheses are being used to create market opportunities (by making for false confidence; but also by engendering exaggerated despair).
