Thereinto, exterior drive mostly arises from the change of competition mode and custom demand, and inside drive includes up-and-up internal force, culture internal force and desire internal force, and the black hole which result from enterprises plough vast capital into information technology compel enterprises to reengineer its business process.

In recent years,with the development of super string theory,manyattempts have been done to explain the statistical origin of black hole thermodynamicsin the frame of string theory.In all these works,the AdS/CFT correspondence conjec-ture attract much attention.

近年来，随着超弦理论的发展，许多学者都试图从超弦理论的角度来研究黑洞热力学，特别是最近AdS/CFT对偶猜想的提出，极大的推动了这方面的研究。

Because no light escapes after the star reaches this infinite density, it is called a black hole.

当恒星的密度达到无穷大时，因为光也逃离不了它，此时的恒星就叫做黑洞。

Since the atoms that make up normal,"solid" matter are mostly empty space, a star made almost entirely of tightly packed neutrons is extraordinarily dense: a fingernail's worth of a neutron star would have a mass of more than a trillion kilograms. A neutron star's density and gravity is second only to a black hole.

确切的说，是直径20km左右的一个超级中子，虽然不过只有一个大中型城市的体积，质量超过1.5倍太阳——译注）由原子组成的普通物质，其&实心&的物质内部其实绝大部分都是空的（大家完全可以用太阳系质量集中在太阳来想象原子内部，当然电子与行星有本质区别——译注），而一颗几乎全部由中子构成的恒星却密度极大：指甲大的一块中子星物质的质量达到万亿吨级，中子星的密度、引力仅次于黑洞。

How unlikely, that a short-lived biped on a two-bit planet should be able to gauge the speed of light, lay bare the structure of an atom, or calculate the gravitational tug of a black hole.

在这个微不足道的星球上，生命短暂的两足动物能够测量光的速度，揭示原子的结构，计算出黑洞的吸引力，是多么的难以置信。

How unlikely, that a short—lived biped on a two--bit planet should be able to gauge the speed of light, lay bare the structure of an atom, or calculate the gravitational tug of a black hole.

一个生命短暂的两足动物居然能够测量出光的速度，揭示出原子的结构，计算出黑洞的引力，这一切是多么不可思议啊！

How unlikely, that a short-lived biped on a two-bit planet should be able to gauge the speed of light, lay bare the structure of an atom, or calculate the gravitational tug of a black hole.

在一个有两颗卫星的星球上，一个寿命不长的双足动物居然能够测量光速，弄清原子的结构，计算出黑洞的引力，真是令人难以置信，这是多么地不大可能。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。
