查询词典 planetesimal

They may have been a source of part of the atmosphere of the terrestrial planets,and they are believed to have been the planetesimal——like building blocks for some of the outer planets and their satellites.

它们可能一直是地球行星的一部分大气的来源。它们还被认为是构成外部行星以及其卫星的一种类似微星的基础材料。

Each planetesimal would have been moving pretty quickly as it crashed into the new planet, and all that speed was converted into another form of energy--heat.

当星子坠向地球时，它的移动速度是非常快的，而且这些速度会转化为另一种形式的能量——热。

In the 19th century, a number of American and English scientists challenged the Nebular theory. They presented the "Planetesimal Theory", or the "Theory of the Little Planets".

在19世纪，一些美国和英国科学家挑战了星云说，他们提出"星子论"，或"小行星学说"。

Indeed, but they all with are the star, in the vast stars two most glisten the planetesimal which but does not make widely known, the nature, refinedly.

的确，但他们又都同为星斗，浩瀚繁星中两颗最闪亮但不张扬的星子，自然、脱俗。

Gravity pulled these planetesimals together, and the young Earth grew slowly, like a snowball, as more and more pieces collided with it. Each planetesimal would have been moving pretty quickly as it crashed into the new planet, and all that speed was converted into another form of energy--heat.

地球的引力将这些小行星体凝聚在一起，就象滚雪球一样，随着越来越多碰撞碎片的聚集，地球的体积日渐成长，每一个星体碰撞形成新饿地球板块时速度及其之快，所有的这些速度形成另一种能量--热量。

It is generally believed that Venus originated with the typical fast and direct rotation. But in the late evolution process, as a result of atmospheric tides and core-mantle friction inside the planet, the rotation is changed gradually. While some others considered that the change of Venus'rotation perhaps due to the early giant planetesimal's collisions.

一般认为，金星原来具有典型的快速正转的状态，在后来的演化过程中，由于潮汐作用或行星内部流体核与幔间的摩擦作用，使得自转逐渐发生变化；也有研究认为可能是早期受到大星子的偶然碰撞所致。

According to the evolution theory of the solar system, the planets were formed from collapse of the planetesimal clouds. The asteroids, occupying the transition region between the rocky terrestrial planets and the outer gas giants with special configuration, underwent the collision evolution process.

按照太阳系的行星由星云塌缩而成的演化理论，对在太阳系中处于特殊位置和具有特殊存在形态的小行星的物理参数的研究，可以为太阳系早期演化条件提供证据；为小行星碰撞演化研究提供边界条件。

The Giant Impactor Theory (sometimes called The Ejected Ring Theory): This theory proposes that a planetesimal the size of Mars struck the Earth just after the formation of the solar system, ejecting large volumes of heated material from the outer layers of both objects.

巨人冲击理论：这种理论认为，一个小行星的火星大小刚刚发生后，太阳系的形成地球，退出从外层激烈的大量材料两个对象。
