gravitational contraction
解釋
引力收縮- gravitational : adj. 【物理學】萬有引力的，地心吸力的。adv. -ly
- contraction : n 1 縮短，收縮；【醫學】攣縮。2 （開支等）縮減；收斂，狹窄；縮度。3 【語法】縮略〈如將 never 略成...

The criterion for gravitational contraction set by equations (3. 4) is significantly weaker for more massive clouds.
由（34）式建立的引力收縮判據，對質量較大的雲是很牽強的。 -
The criterion for gravitational contraction set by equations ( 3. 4 ) is significantly weaker for more massive clouds
由（ 3 4 ）式建立的引力收縮判據，對質量較大的雲是很牽強的。 -
The electron degenerate pressure does not come from the burning of any nuclear fuel and can therefore support the star from further gravitational contraction forever
電子簡並壓力並非來自任何核反應所以它能永遠抵抗恆星的引力。 -
The helium core of the star starts to collapse. this gravitational contraction will heat up the hydrogen envelope surrounding the core. fusion therefore begins in the envelope and the star expands
剩下的氦核心便會開始塌縮並產生熱，緊鄰核心的氫外殼會被加熱而開始有熱核反應恆星亦同時膨脹。 -
Can stop the star from further collapsing. note : again, neutron degenerate pressure does not come from nuclear burning. it can support a neutron star from further gravitational contraction forever
則足以防止恆星進一步收縮同電子簡並壓力一樣中子簡並壓力並非來自核子反應它可永遠?抗恆星的引力收縮。
