density of the universe 中文意思是什麼

density of the universe 解釋
宇宙的密度
  • density : n. 1. 稠密；濃厚。2. 【物理學】濃度；密度；比重。3. 愚鈍，昏庸。
  • of : OF ＝Old French 古法語。
  • the : 〈代表用法〉…那樣的東西，…那種東西。1 〈用單數普通名詞代表它的一類時（所謂代表的單數）〉 （a） 〈...
  • universe : n. 1. 宇宙；萬有，天地萬物，森羅萬象；全世界；全人類。2. 全領域；【統計學】全域；【邏輯學】整體。3. 【天文學】銀河系；恆星與星辰系。
  1. In recent years researchers have calculated that if a value called omega, the ratio between the average density of the universe and the density that would halt cosmic expansion had not been within about one quadrillionth of one percent ; does anyone know hot to write that number

    聽著，最近從事研究的人計算到，若一個值稱為亞米加，宇宙平均密度與停止宇宙擴張的密度的比例，少於百分一的千萬億分一。誰知道這怎麼寫？
  2. In the case of an open universe, the mass density ( denoted by the greek letter omega ) is less than unity, and the universe is predicted to expand forever

    在一開放的宇宙里，質量密度（以希臘字母歐米加表示）是小於平均數，且宇宙被預言永遠地膨脹下去。
  3. It is the simplest theory that agrees with the cosmological principles and most observational facts in our universe. it states that when the age of the universe was about just 1ms, the universe was very small, with very high density and temperature about 10

    宇宙不是無紿無終的，它亦有一個起源，一個誕生點，當宇宙的年只有1微秒的時候，宇宙的一切皆擠壓在一個細小高密度的熾熱火球內，溫度達10
  4. As an extension of the big bang theory, inflation theory predicts the universe density is rather close to the critical density. thus, the universe is flat

    根據為改進大爆炸理論而發展出來的暴脹理論，宇宙密度必定接近於臨界密度，所以宇宙應是平坦的。
  5. Their standard model treats the universe as though its density did not vary from place to place but had a uniform, average value of one atom per cubic meter

    標準模型將宇宙視為一個均勻結構，密度不會隨著空間位置而變化，每立方公尺平均有一個原子。
  6. How the universe evolves is affected by three factors, namely the mean density of mass - energy, the space - time curvature and a mysterious factor, the cosmological constant

    宇宙尺度的變化受三個因素影響：宇宙中質量-能量的平均密度宇宙的時空曲率與及一個神秘因素宇宙常數。
  7. The future of the universe is mainly determined by the mean density of mass - energy and the space - time curvature, while cosmological constant does not carry any weight among popular cosmological theories

    現在流行的宇宙論都不考慮宇宙常數，宇宙的未來完全由質量能量的平均密度及宇宙的時空曲率來決定。
  8. We currently have a coherent model that tracks the growth of subtle density fluctuations laid down in the early universe to the present richness of the night sky

    現在我們擁有一致的理論模型，能夠描述早期宇宙密度的細微起伏，一路上是如何成長，而成為現在夜空中的豐富結構。
  9. The big bang model, which states that almost 14 billion years ago the universe started expanding from a state of extremely high density and temperature, is able to explain galaxy motions, the abundance of hydrogen and helium, and the properties of the cosmic microwave background ( cmb ), the remnant heat from the expanding and cooling gas

    大霹靂模型指出，宇宙于約140億年前自極度高溫、高密度的狀態開始擴張，這理論不但可以解釋星系運動以及宇宙中氫與氦的含量，而且還預測了宇宙擴張時，冷卻中氣體的殘餘熱輻射，也就是宇宙微波背景的各項性質。
  10. Mass density is the physical quantity determining the future of the universe. there is a value called the

    宇宙的質量密度決定了宇宙的命運，假若質量密度大過某一稱為
  11. On the other hand, if the mean density of mass - energy is too low, the universe will keep on expanding forever, resulting in an open universe

    相反，若質量能量的平均密度太低的話，宇宙會無休止地膨脹下去，成為一個開放的宇宙。
  12. If the density of matter and energy in the universe is less than the critical density, the space curvature will be negative

    事實上，宇宙中暗物質和暗能量的多寡決定了宇宙的幾何結構。假若宇宙中的物質和能量的總密度低於臨界密度，它是一個空間曲率
  13. A parameter known as the " mass density " - that is, how much matter per unit volume is contained in the universe - determines which of the three possibilities applies to the universe

    以「質量密度」聞名的一個參數-也就是，在宇宙里含有多少單位體積物質?確定三種可能性哪一種適用於宇宙。
  14. The density of the universe is still unknown. one of the major problems is the existence of

    要準確量度宇宙的質量密度非常困難，最大的障礙來自宇宙的
  15. Therefore, data from a wide variety of independent cosmological and astrophysical observations strongly suggest that most of the energy density of the universe today may be contained in empty space

    換言之，不同的研究和觀測數據皆表明，現時宇宙中大部份的能量密度很可能隱藏於虛空之中！
