引力势能

吸积盘内缘区域的波阻将使盘内的角速度偏离开普勒速度而减小，引力势能使流体加热和加速。

In the transition region of accretion disk , the angular velocity deviates from and is smaller than the Keplerian angular veloeity if the wave dissipations are included , and the gravitational potential energy will convert into heat or kinetic energies of accretion gas .

它包括由质量守恒方程、动量守恒方程和能量守恒方程构成的Euler方程组以及由星体本身的密度分布决定的自引力势能所满足的Poisson方程。

It contains Euler equations for conservation of mass , momentum and energy , and Poisson equation through which the gravitational potential is determined by the density distribution of the gas itself .
