As gravity pulls a star's gas inward, pressure increases and pushes the matter back outward.

当重力将恒星的气体向内拉时，压力增加并将物质推向外部。

The core of the star, no longer supported by the outward pressure generated by fusion, rapidly collapses from the enormous inward pressure of gravity.

恒星的核心不再受到核聚变产生的向外压力的支撑，在重力巨大的向内引力压力下迅速崩溃。

It was under strong inward pressure of this kind that Fred had taken the wise step of depositing the eighty pounds with his mother.

正是在这种强大的内心压力下，弗雷德才明智地采取了将八十英镑存入母亲的步骤。
