吸積盤內的粒子在失去重力位能的過程中加速 Particles within an accretion disk increase speed as they lose gravitational potential energy

吸積盤內的粒子隨著速度增加與角動量減少而輻射出更多能量 Particles within an accretion disk radiate more energy as their speed increases and their angular momentum decreases

吸積盤內的粒子在失去角動量時會加速移動 Particles within the accretion disk accelerate as they lose angular momentum

吸積盤內的粒子逐漸喪失角動量 Particles within the accretion disk gradually lose angular momentum
