地球

If they figure out how to play it, they will hear greetings in 60 Earth languages, as well as the natural sounds of the planet -- thunder clapping, frogs croaking and a newborn baby crying.

如果他们揣测出怎样摆弄唱盘，他们将听到地球上大自然的声音——雷鸣声，青蛙的呱呱声，以及新生婴儿的哭喊声；他们还将听到六十种地球上的问候语。

The attraction that the earth has for every particle or body on its surface is meant by gravity.

地心引力指的是地球把每一粒子或物体保留于地球表面的吸引力。

Nevertheless, the smaller mass (1 / 80th that of the earth) and size make the moon's surface gravity only about one-sixth that of the earth.

但是，由于它质量较小(为地球质量的1/80)，体积较小，致使其表面的重力仅为地球的1/6。

Very fresh: the sun and the moon Centre Centre at the smallest distance.- Health: the sun and the moon, the second cut, sun-exposed just west of the moon moment.

如果月球本影比地球与月球之间的距离小，月球本影的尖端到不了地球的表面，那么在影尖延长出来的小影锥扫过的地带可以看到日环食。

The great circle representing the apparent annual path of the sun; the plane of the Earth's orbit around the sun; makes an angle of about 23 degrees with the equator.

在地球上看到的太阳运行的轨道；地球绕着太阳转的平面；与赤道平面大致成度角。

They found that its orbit is inclined at 30 degrees to the Earth's, the same angle at which the star's disc of dust and gas is tilted.

他们发现这颗行星轨道同地球的倾角是30度，而恒星的碎屑盘相对地球倾斜的角度同样是30度。

Processes that affect organic molecules stretch from biochemistry to geochemistry and transport us from star dust to mountains to the humble mud of ancient oceans.

影响有机分子从生物化学到地球生物化学的过程，使我们的地球将星际灰尘变成了山脉，然后就变成了我们最普通的原始海洋沉积物。

From a vantage point outside our home, a revealing perspective has shown us the planet for what it really is; a ball of living star dust, a four-and-one-billion year old miracle.

从地球以外的有利地位来看，地球是一个有生命的、虚无缥缈的球体，一个有着50亿年生命的奇迹。

From a vantage point outside our home, a revealing perspective has shown us the planet for what it really is; a ball of living star dust, a four-and-one-billion year old miracle.

从地球以外的有利地位来看，地球是一个有生命的、虚无缥缈的球体，一个有著50亿年生命的奇迹。

The transition from a believing that the earth stands still at the center of the universe, to believing that the earth is a planet that moves in various ways two ways primarily spinning around its own axis every twenty-four hours and going around the sun in uh, an orbit once a year.

由相信地球静立在宇宙中心，转变为相信地球为行星之一，以各种不同的方式转动，其中两种主要方式是：每24小时依地轴自转一周，而每年依天体轨道绕太阳公转一周。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
