辐射流体动力学。速度或高光学厚度的流动应该在严格的相对论形式主义下处理。总结了相对论辐射流体动力学矩方程，讨论了它在中子星星近临界吸积中的应用。即使在重力较弱和速度较小时，相对论效应也可以支配流动的动力学。一阶方程不能正确描述复杂的相对论效应。
Radiation hydrodynamics in high. velocity or high optical-depth flow should be treated under rigorous relativistic formalism. Relativistic radiation hydrodynamic moment equations are summarized, and its application to the near-critical accretion onto neutron star is discussed. The relativistic effects can dominate the dynamics of the flow even when the gravity is weak and the velocity is small. First order equations fail to describe the intricate relativistic effects correctly.
