论文摘要
在这篇方法学论文中，我们考虑了球形对称的黑洞空间时间中颗粒的大地运动运动。我们开发了一种基于自由下落粒子到流速的速度的方法，该速度仅取决于度量，并偏离它（特殊的速度）。它适用于一类球形对称的指标，并在Schwarzschild黑洞的地平线下开发。目前的工作概括了纯径向运动获得的先前结果。现在，运动通常是非放射线，因此观察者可以具有非零的角动量。这种方法使我们能够对地平线内的红移（Blueshift）进行简单的物理解释，包括奇异性附近的区域，并同意通过直接计算获得的最新结果。
In this methodological paper we consider geodesic motion of particles in a spherically symmetric black hole space-times. We develop an approach based on splitting the velocity of a freely falling particle to the flow velocity, which depends only on a metric, and deviation from it (a peculiar velocity). It applies to a wide class of spherically symmetric metrics and is exploited under the horizon of the Schwarzschild black hole. The present work generalizes previous results obtained for pure radial motion. Now, the motion is, in general, nonradial, so that an observer can have a nonzero angular momentum. This approach enables us to give simple physical interpretation of redshift (blueshift) inside the horizon including the region near the singularity and agrees with the recent results obtained by direct calculations.
