地球

If the results prove to be valid geophysicists will have a new theory to guide them in their quest to understand the earth's inner physics.

CET-6 1999.1 Passage2 Paragraph3 如果这个结论被证明是有根据的，地球物理学家们将需要一个新的理论来指导他们了解地球内部的物理情况。

VRGIS is a virtual reality technology, which can researches geosciences or takes geoscientific system as object, as well as is a rising research branch of GIS recently.

虚拟现实地理信息系统(Virtual Reality Geographic Information System，简称VRGIS)是虚拟现实与地理信息系统相结合的技术，是一种用于研究地球科学的，或以地球科学系统为对象的虚拟现实技术，也是近年来一个新兴的地理信息系统的研究分支。

As the name suggests, a geostationary satellite is stationary relative to the earth.

恰如其名，地球同步气象卫星相对地球是静止不动的。

The satellite placed in a geosynchronous orbit revolves once a day with the earth, so it appears to be fixed over one place at all the time.

地球同步轨道上的卫星，每天随地球转一圈，所以看上去似乎总固定在一处。

His idea was to put a weight of some kind in geosynchronous orbit around the earth. This weight would be attached to the surface of the earth, allowing people to go up and down the tether.

这个概念是通过在地球的同步轨道上放置某种重物，这个重物需要连接到地球表面，人们通过系链上下穿梭。

A futuristic scheme that has been proposed to produce power on a large scale envisions placing giant solar modules in geosynchronous earth orbit, where energy generated from sunlight would be converted to microwaves and beamed to antennas on earth for re-conversion to electric power.

有一个未来的方案被提议是大胆的设想在地球同步轨道上安置太阳能模块来制造能量，能量从太阳光中产生就能够被转化成微波和直播传给地球上的天线来再次转化为电能。

Because of the absorption of ozonosphere existing in higher level atmosphere,the sun-blind-region ultraviolet radiation (200～280nm) of solar spectrum could hardly reach the surface of the earth. Therefore, the communication system using this spectral coverage could hardly be disturbed.

由于地球大气上层臭氧的吸收作用，阳光中的日盲区(200～280nm)辐射几乎无法到达地球表面，因此，采用这个波段的光学通信系统几乎不会受到太阳光的干扰。

At present, our country's fire situation is austere. Currently the mostly used fire extinguishment products is tend to destroy the ozonosphere being located at 25 to 40 kilometers above the earth, which imperil to human beings and the earth ecological balance.

现阶段我国火灾形势严峻，而防治火灾时，当前应用最多的卤代烷系列灭火剂产生的自由基会严重破坏位于地球上空25～40公里处的臭氧层，从而威胁人类生存，危及地球生态平衡。

There is a film called "The Quiet Earth" in which story - except for three people - all human and animal lifeforms disappear from the face of the earth, respectively they are transported to another dimension.

DO ：有部叫做《寂静的地球》的电影，电影里，除了三个幸存者，其他所有的人类和动物都从地球上消失了，他们分别被转移到其他的地方去了。

A new kind of tree could cool the planet by removing a major greenhouse gas from the planet's atmosphere.

这是一种新式人造树，它能够将地球大气所含的高比重温室气体一网打尽，从而令地球的气候转暖为凉。

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。
