  1. Witten ' s open string field theory formulate the interaction of bosonic open strings in the language of noncommutative geometry. compactification of matrix theory on the noncommutative torus was argued to correspond to supergravity with constant background three form tensor field. more generally, it has been realised that noncommutative gauge theory arises in the worldvolume theory on d - brane in the presence of a constant background b field in string theory

    Witten的開弦場論用非對易幾何描述了玻色開弦的相互作用；在非對易torus上的矩陣理論的緊化對應于帶有常數三形式張量場的超引力；更為普遍的，非對易規范理論可以自然地產生在帶有常數b背景場的三維d - brane上。
  2. This set of vacuum energies ( or vacua, as physicists like to refer to universes ) has been dubbed the anthropic landscape of string theory

    而這組真空能量（或稱多真空，對應到物理學家提及的多宇宙）便被戲稱為弦論的人擇地景。
  3. String theory, which unites gravity with quantum mechanics, offered the hope of explaining the attenuated cosmological constant

    統合重力及量子力學的弦論，似乎能為微小的宇宙常數提供一個合理解釋。

    本文用brown - york準定域能定義對弦理論中的一些黑洞的能量進行了計算，並探討了源於廣義相對論中kerr黑洞的martinez猜測在弦理論中的適用性。
  5. 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 .考慮垂度和抗彎剛度對高階自振頻率的影響，探討了索相鄰頻率之差，發現索的高階頻差就是弦振動理論的基頻，利用這一特性，分析了頻差法測索力的精度和適用范圍。
  6. The cable tension plays an important role in the construction control and long - term monitoring of cable - supported structures. the engineering implementation of a vibration - based cable tension evaluation is mostly carried out based on the taut string theory where the cable tension is estimated from measured natural frequencies by use of a simple explicit formula

    振動法測索力廣泛應用於索結構的施工控制和健康監測，其原理是基於弦振動理論：索拉力與自振頻率之間存在簡單的關系，因此可以由實測的自振頻率計算得到索力。
  7. A very promising approach to a quantum theory of gravity is string theory, which some theoretical physicists have been exploring since the 1970s

    弦論是廣被看好的一種建構量子重力論方式，一些理論物理學家自1970年代以來就在研究這項理論。
  8. 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，弦論無法以實驗來檢驗，因為弦論所涉及的能量太高，物理學家在實驗室中造不出那麼高的能量，但是鞏訥指出非可換幾何所做的預測，譬如希格斯質量（ 1600億電子伏特） ，卻是可以檢驗的，他說甚至重整化也可以證實。
  9. The kaluza - klein idea has been resurrected and extended as a feature of string theory, a promising framework for the unification of quantum mechanics, general relativity and particle physics

    卡魯扎?克萊恩的觀念被重新提起，並且被擴充為弦論的特色之一，而弦論是個非常有希望能統一量子力學、廣義相對論與粒子物理的架構。
  10. String theory overcomes some of the obstacles to building a logically consistent quantum theory of gravity

    在建構沒有矛盾的量子重力論時，弦論已克服了某些障礙。
  11. Evidence for supersymmetry at high energy would be compelling evidence that string theory was a good mathematical model for nature at the smallest distance scales

    高能量超對稱性的證據將令人信服表明弦理論對于自然界在最小的距離范圍內是一個很好的數學模型。
  12. 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

    當重力在微觀距離作用時，比如說，在黑洞的中心，極大量的質量被擠進一個次原子的體積中，物質那不尋常的量子性質就會顯現出來，而弦論則描述了重力定律在此處如何改變。
  13. Historically, angular momentum is what clued in physicists to the quantum - gravitational implications of string theory

    歷史上，角動量正是讓物理學家注意到弦論中含有量子重力的關鍵。
  14. In both the kaluza - klein conjecture and string theory, the laws of physics that we see are controlled by the shape and size of additional microscopic dimensions

    在卡魯扎?克萊恩的推測與弦論中，附加的微觀維度的形狀與大小，支配了我們所知的物理定律。
  15. After string theory made its comeback as a theory of gravity in the 1980s, veneziano became one of the first physicists to apply it to black holes and cosmology

    在1980年代，弦論以重力理論之姿重新出發之後，維納齊亞諾便成了首度將它應用在黑洞和宇宙學的物理學家之一。
  16. 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

    維納齊亞諾是歐洲核子研究組織（ cern ）的理論物理學家，也是1960年代晚期的弦論之父；為此成就，他獲得今年美國物理學會與美國物理協會的海曼獎。
  17. 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 ]

    因為參數不只一個，我們實際上應把這個真空能量曲線想像成是一個復雜、多維度山脈的剖面，美國史丹佛大學的色斯金將此描述成弦論地景（請見73頁能量地形的中圖） 。
