Schwarzschild Metric

释义 Definition

Schwarzschild metric(施瓦西度规):广义相对论中描述非旋转、无电荷、球对称质量(如理想化的黑洞或恒星外部)周围时空几何的一个精确解。它引入了史瓦西半径事件视界等关键概念。(该词组在更广语境下也常与“Schwarzschild solution/施瓦西解”互换使用。)

例句 Examples

The Schwarzschild metric describes the spacetime outside a non-rotating black hole.
施瓦西度规描述了非旋转黑洞外部的时空结构。

Using the Schwarzschild metric, we can derive the gravitational time dilation and the bending of light near a massive body in the weak-field limit.
利用施瓦西度规,我们可以在弱场近似下推导出引力时间膨胀以及光在大质量天体附近的弯曲。

词源 Etymology

“Schwarzschild”来自德国天文学家与物理学家Karl Schwarzschild(卡尔施瓦西)之姓;他在1916年给出爱因斯坦场方程的第一个精确解之一。“metric”源自希腊语词根,意为“测量”,相对论中指用于计算时空间隔的“度规张量”。
