We study the self-force acting on a scalar charge in uniform circular motion around a Schwarzschild black hole. The analysis is based on a direct calculation of the self-force via mode decomposition, and on a regularization procedure based on Ori's mode-sum regularization prescription. We find the four self-forces at arbitrary radii and angular velocities (both geodesic and nongeodesic), in particular near the black hole, where general-relativistic effects are strongest, and for fast motion. We find the radial component of the self-force to be repulsive or attractive, depending on the orbit.
我们研究了作用于在史瓦西黑洞周围做匀速圆周运动的标量电荷上的自力。该分析基于通过模式分解对自力的直接计算，以及基于奥里模式求和正则化方法的正则化过程。我们求出了在任意半径和角速度（包括测地线和非测地线情况）下的四个自力，特别是在黑洞附近，那里广义相对论效应最强，以及对于快速运动的情况。我们发现自力的径向分量是排斥的还是吸引的，取决于轨道。
