4周搞定2000+托福核心词
ity = ity(名词) = 能力
affinity = af(再) + fin(范围) + ity(名词) = 进入范围内→密切关系
速度
velocity
常考释义
First through a low velocity core, and then through a high velocity shell, where their speed is increased before they are transmitted into the surrounding seawater.
先经过一个低速率中心,再经过一个高速率框架,在声波进入海水之前将声波的速度提高。

Acceleration and velocity are both vectors.
加速度和速度都是矢量。
But let's apply it in the end to an instantaneous velocity.
最后让我们把它应用于瞬时速度上。

If current velocity continues to decrease - as a flood wanes, for example - finer particles settle out on top of the large ones.
如果水流的速度继续减弱——比如洪水消退时——更细的颗粒会沉淀在大颗粒上。
来源于:阅读OFFICIAL52 P1This downstream sorting is curious because stream velocity generally increases in the downstream direction.
这种顺流而下的分类是很奇妙的,因为河流的速度通常在下游方向加快。
来源于:阅读OFFICIAL52 P1Competence increases with velocity, so a river should be able to transport larger particles than its tributaries carry.
水流的携带能力随着流速的加快而提升,因此一条河流可以输送的颗粒应该比它的支流所携带的颗粒更大。

如果一条陡峭的山溪流到平坦的平原上,它的坡度和速度就会急剧下降。

先经过一个低速率中心,再经过一个高速率框架,在声波进入海水之前将声波的速度提高。
来源于:听力OFFICIAL23 L5The Jovian planets, because of their greater masses and thus higher surface gravities, have higher escape velocities (21-60 kilometers per second) than the terrestrial planets.
由于类木行星的质量较大并因此产生更高的表面引力,因此,类木行星的逃逸速度(21~60千米/秒)要比类地行星高得多。
