在本片的一个场景中，超人悬浮在地球之上，观众听到他那位外星父亲的画外音。
In one scene, as Superman floats above the Earth, we hear his alien father in a voiceover.
这是第一个试图勘测整个世纪地球表面自然(非人造)环境中悬浮颗粒的研究。
It's the first study to trace the fluctuation of a natural (not human-caused) aerosol around the globe over the course of a century.
将悬浮粒子注入平流层，或是云层亮化方案都不仅仅是对地球降温。
Injecting aerosols into the stratosphere or brightening clouds would do more than just cool the planet.
尽管煤炭的燃烧会产生大量的温室气体二氧化碳，但是它也把大量的硫酸盐悬浮颗粒扩散到大气中。这些悬浮颗粒把太阳光反射回太空中，从而给地球降温。
Although burning the coal produced more warming carbon dioxide, it also put more tiny sulphate aerosol particles into the atmosphere which cool the planet by reflecting solar energy back into space.
OMI传感器可以区分云、烟、灰尘、臭氧和其他悬浮颗粒，在为保障航空安全而进行的地球观测中十分重要。
The OMI sensor can distinguish the differences between cloud, smoke, dust, ozone and other aerosols, and is important in Earth observations for aviation safety. AP / NOAA
严重的问题是被污染了的空气悬浮在地球表面。
The serious problem is that the polluted air is hovering over the surface of earth.
在那里，气态硫转化为可以反射阳光并令地球冷却的硫酸盐悬浮微粒。
There, the sulfur gas transforms into a sulfate aerosol that reflects sunlight and cools the planet.
圣诞老人的线路最好是与地球自转逆向而行，而不是悬浮在空中、等着各家各户随着地球自转来到他的脚下。
But instead of hovering over a longitude waiting for the Earth's rotation to bring homes to him, Santa can do better by travelling backward against the direction of Earth's rotation, notes the author.
悬浮在地球上空的冰天之所以坍塌，是直接归因于黄金及维系冰天的其它矿石的丢失的。
The loss of the ice shields that once were suspended around earth in her atmosphere was directly due to a loss of gold and other minerals to hold them in place;
地球在开始形成时，是温度极高的液态，又因为它是悬浮在太空中的，所以变成了圆球形。
Wen the Earth formed, it was hot and liquid. Because it was floating in space, it became round.
从前许多科学家认为只有那些较轻的能够引起温室效应的气体，例如二氧化碳，才能够围绕地球游动，但是现在看来带有悬浮颗粒的烟雾也是可以的。
While many scientists once thought that only lighter greenhouse gases, such as carbon dioxide, could travel across the Earth, they now say that aerosol clouds can too.
