String Field TheoryString field theory (SFT) is a formalism in string theory in which the dynamics of relativistic strings is reformulated in the language of quantum field theory. This is accomplished at the level of perturbation theory by finding a collection of vertices for joining and splitting strings, as well as string propagators, that give a Feynman diagram-like expansion for string scattering amplitude

Outline of string theory弦论列表

英汉例句

• that「s why string theory also is sometimes called a theory of everything, because it could serve someday as a foundation for all future scientific discovery and innovation.

  这就是为什么有时候弦论被称为一切的理论，因为有一天它会成为所有未来科学发现和革新的基础。

• recently, though, string theory has acquired a rival, known as loop quantum gravity.

  然而最近，弦理论遇到了一个劲敌：圈量子引力理论。

• however, they have two major challenges to overcome if they are to persuade the rest of the scientific community that string theory is the best candidate for a toe.

  但是，如果要去说服科学界弦论是万有理论的最好代表，这些变体还要跨过两个主要的挑战。

• just how many hidden dimensions exist depends on the theory, but some versions of the popular string theory for example, postulate we live in a 10- or 11-dimensional universe.

  究竟存在着多少隐藏的维度，这个问题仅依赖于理论，但流行弦理论的一些版本，作为例子，假设我们生活的宇宙，有10维或11维。

• this can be measured in a lab, and the results will demonstrate whether string theory actually works.

  这可以在实验室中进行测量，而且结果将证明弦论是否真正有效。

• what」s more, the mathematics of string theory also rely on extra spatial dimensions, which humans could not experience directly.

  而且，弦论力学依靠于超三维空间，这人人类所不能直接体验的。

• string theory is the more established of the two; some 90% of theoretical physicists are engaged in developing it.

  同环圈量子重力学相比，超弦理论的根基更为牢固，约有90％的理论物理学家致力于发展超弦理论。

• however, most string theory models are based upon certain mathematical assumptions, and what we ve shown is that such string theories have some definite predictions that can be tested.

  然而，大多数弦理论模式都是基于确定的数学猜想，我们所需要说明的东西就是此类弦理论有一些明确的预测可以检测到。

• it turns out that string theory predicts the behavior of entangled quantum particles, which can be tested in a lab — therefore testing string theory.

  结果是弦论能够预测纠缠态的量子粒子的行为表现，而这种行为表现可以在实验室中进行检验——因此最终可以对弦论进行检验。

• you’re not going to meet a ph.d. in string theory or hear a talk about playing the lute at davos the way you do at ted.

  不过你别指望在达沃斯上碰到一个谈论超弦理论string theory的物理学博士，或是听到有人用在ted上的方式来谈论该怎么弹奏琉特琴。

• most of us are happy to admit that we do not understand, say, string theory in physics, yet we are all convinced we understand evolution.

  虽然我们大多数人乐于承认，比如说，我们不懂物理学中的弦理论，但我们都确信我们理解进化。

• string theory smooths out the mathematical inconsistencies that currently exist between quantum mechanics and the theory of relativity.

  弦理论缓和了量子力学和相对论之间的数学矛盾。

• ahead of the official announcement, one scientist said it was an excellent appointment for a physicist who had been a driving force for string theory from the start.

  在官方发表声明之前，一位科学家说，让一位从弦理论创始之初就大力推动其发展的科学家获此殊荣，这次任命实至名归。

• he is lead author of a paper to be published tomorrow in physical review letters, which explains how string theory math can be used to predict quantum entanglement.

  他是今天发表在《物理评论快报》（physicalreviewletters）杂志上的一篇论文的领衔作者，这篇论文解释了弦论数学如何能够被用于预测量子纠缠。
