  • 例句与用法
  • The brown - york quasilocal energies of some black holes in string theory are calculated and martinez ' s conjecture , originally proposed for the kerr black hole in general relativity , is explored in string theory
    本文用brown - york准定域能定义对弦理论中的一些黑洞的能量进行了计算,并探讨了源于广义相对论中kerr黑洞的martinez猜测在弦理论中的适用性。
  • In order to include fermions in string theory , there must be a special kind of symmetry called supersymmetry , which means for every boson ( particle that transmits a force ) there is a corresponding fermion ( particle that makes up matter )
    为了将费米子列入弦理论中,必须有一种特殊的对称即超对称,这意味着每一个玻色子(能够传力的粒子)都有有一个相应的费米子(组成事物的粒子) 。
  • Gabriele veneziano , a theoretical physicist at cern , was the father of string theory in the late 1960s ? an accomplishment for which he received this year ' s heineman prize of the american physical society and the american institute of physics
    维纳齐亚诺是欧洲核子研究组织( cern )的理论物理学家,也是1960年代晚期的弦论之父;为此成就,他获得今年美国物理学会与美国物理协会的海曼奖。
  • When gravity operates over microscopic distances ? for instance , at the center of a black hole , where a huge mass is packed into a subatomic volume ? the bizarre quantum properties of matter come into play , and string theory describes how the law of gravity changes
    当重力在微观距离作用时,比如说,在黑洞的中心,极大量的质量被挤进一个次原子的体积中,物质那不寻常的量子性质就会显现出来,而弦论则描述了重力定律在此处如何改变。
  • The second is that einstein ' s general relativity , which is a part of string theory , implies that the universe can grow so rapidly that different configurations will coexist side by side in different subuniverses , each large enough to be unaware of the others
    其次,做为弦论的一部份,爱因斯坦的广义相对论暗示了宇宙可迅速成长,使得不同的组态可以并列共存于不同的次宇宙里;而且每个组态虽然都够大,却察觉不到另有别的组态存在。
  • Because there is more than one parameter , we should actually think of this vacuum energy curve as one slice through a complex , multidimensional mountain range , which leonard susskind of stanford university has described as the landscape of string theory [ see middle illustration on page 85 ]
    因为参数不只一个,我们实际上应把这个真空能量曲线想像成是一个复杂、多维度山脉的剖面,美国史丹佛大学的色斯金将此描述成弦论地景(请见73页能量地形的中图) 。
  • One promising and comprehensive approach to this ultimate theory is string theory , which is based on the idea that all particles and forces can be described in terms of one - dimensional objects ( “ strings ” ) , along with membranes of two dimensions and higher that are called branes [ see “ the string theory landscape , ” by raphael bousso and joseph polchinski , on page 78 ]
    在追求终极理论方面,弦论是一个很有希望又具全面性的途径,其中心思想是认为所有粒子与作用力都可以用一维的弦、二维以及更高维的薄膜来描述(参见第66页一统宇宙的弦论) 。
  • Whereas string theory cannot be tested directly ? it deals with energies that cannot be created in the laboratory ? connes points out that noncommutative geometry makes testable predictions , such as the higgs mass ( 160 billion electron volts ) , and he argues that even renormalization can be verified
    例如,弦论无法以实验来检验,因为弦论所涉及的能量太高,物理学家在实验室中造不出那麽高的能量,但是巩讷指出非可换几何所做的预测,譬如希格斯质量( 1600亿电子伏特) ,却是可以检验的,他说甚至重整化也可以证实。
  • The cable sag and bending stiffness effects are studied on the higher natural frequencies of cable vibration . it is found that the differences of the higher adjacent frequencies go to the fundamental frequency of the taut string theory even though the cable sag or bending stiffness is included . this unique characteristic of cable vibration is used to determine the cable tension with the well - known taut string theory
    2 .考虑垂度和抗弯刚度对高阶自振频率的影响,探讨了索相邻频率之差,发现索的高阶频差就是弦振动理论的基频,利用这一特性,分析了频差法测索力的精度和适用范围。

  • 英文解释
  • (particle physics) a theory that postulates that subatomic particles are one-dimensional strings

  • 百科解释
String theory is an active research framework in particle physics that attempts to reconcile quantum mechanics and general relativity. It is a contender for a theory of everything (TOE), a self-contained mathematical model that describes all fundamental forces and forms of matter.
