cosmic constant 中文意思是什麼
cosmic constant
解釋
宇宙常量-
When the field is slowly - varying, the scalar field potential acts like a cosmological constant. in addition to the quintessence models, many other theories for dark energy have been proposed, including models based on super - symmetric gauge theories, super - gravity, small extra dimensions, large extra dimensions, quantum field theory effects in curved space - time. all these models are essentially based on the existence of a mass less scalar field acting at a cosmic scale
除了真空場模型外，科學家亦提出其他解釋黑暗能量的理論，這些模型建基於不同的物理理論或假設，例如超對稱規范理論超重力增加一些小或大的空間維數量子力學在彎曲時空的影響等等，這些理論模型，返本溯源，其實背後都假設存在著一個特性類似於宇宙常數的無質量純量場。 -
We find that the cosmic scale factor has the form of exponent inflation if the cosmological constant contributes to the positive material density, and the factor is composite function of cosine if the cosmological constant contributes to the negative material, furthermore, we gain the new formality of the pressure and the temperature in the procedure of cosmological evolution
首次發現當宇宙學常數對物質密度的貢獻大於零時有指數復合函數的型得一般暴漲，當宇宙學常數對密度的貢獻小於零時宇宙有餘弦形式的演化。通過對宇宙中壓強和溫度的計算，得到新的壓強表達式和暴漲宇宙模型中溫度隨時間演化的表達式。 -
And in the lion s invigorating swiftness samadhi, the bodhisattva, mahasattva revels in the stillness of constant flexing, inspiring every conceivable transformation from his cosmic mind
此時懊惱又轉為切心的關懷。也許他被人綁架打劫，或者受傷撞車，可能掉進山溝里死了。
