cosmological constant的用法和樣例：
例句
- Therefore, the irreducible warp of the brane acts like a cosmological constant, which speeds up cosmic expansion.
因此，這膜上無(wú)法消除的時(shí)空彎曲就表現的如同宇宙常數，導致了宇宙的加速膨脹。 - But to produce the observed acceleration of the universe, the constant's density would have to be twice that of matter.
但若想造成現今觀(guān)測到的加速膨脹，則這個(gè)宇宙常數的能量密度須為物質(zhì)密度的兩倍。 - If only conservation forces act, the kinetic energy plus the potential energy remains constant.
如果只受保守力的作用，則動(dòng)能加勢能是一個(gè)恒量。
