The light emitted from a Keplerian ring around the objects with strong gravitational field should be affected by Doppler shift, gravitational redshift and deflection of light. The line profiles for a faraway observer are dominated by these effects. In this paper the precise solutions of line profiles for the Keplerian rings in the Schwarz-schild case have been obtained by means of the kinetic equation for photons.

对于一个围绕强引力场物体作开普勒运动的环状发光物，它所发射的光线要受多普勒频移，引力红移和光线偏折等效应的作用，这种作用决定了远处观察者所看到的谱线轮廓，本文利用光子输运方程方法，求出在Schwarzschild度规中的开普勒环所发射的谱线的轮廓的精确解。

These problems together with the infinities in the quantization of gravitational field indicate strongly that there must be a rigorous examination of Einstein's geometrized theory of gravitation, especially a careful investigation of the role of vacuum in gravitational interaction.

另一方面，当前天体物理学和宇宙学中面临两个扑溯迷离的重大问题，即与星系转动曲线异常和宇宙加速膨胀等一系列问题相联系的暗物质、暗能量问题。
