| 在某些情况，外向流动很可能对吸积盘具有支配性的影响，因为它们向外携带的不仅是质量与能量，或许还有很显著的角动量。 |

| 碰撞使环具有放射状散开的倾向，但土星的卫星会储存角动量，而使环保持封闭性。 |

| 在剑桥当研究员时，他再接再励，并推测出：可能是产生宇宙的大爆炸同时也产生了那些小黑洞，其大小同质子差不多，但质量却重如一座大山。 |

| 15. | The strength of the magnetic field increases as the particle's momentum increases. |
| 同步加速器: 环形的粒子加速器，用磁场把粒子限定在它们的轨道上。磁场强度随着粒子动量的增加而增加。与粒子的轨道频率同步的交流电场使粒子加速。 |

| 16. | Saturn's rings: as the pebbles, rocks and boulders that make up the rings collide, their energy is lost as |
| 例如在土星环上：当组成环的细小石砾、石或巨石发生碰撞，能量会转化为热而丧失，且角动量会向外传输。 |

| 草坪从海滩起步，直奔大门，足足有四分之一英里，一路跨过日文、砖径和火红的花园——最后跑到房子跟前，仿佛借助于奔跑的势头，爽性变成绿油油的常春藤，沿着墙往上爬。 |
