It maps the entire earth by using images obtained from satellite imagery, aerial photography and GIS over a 3D globe.

它的地图整个地球用图像获得的卫星图像，航空摄影和地理信息系统的一个三维世界。

As the wide existence of steady liquid water on the red planet has been more and more clearly proved ,and the idea that bacterielles fossil was brought to the earth by an aerolite from the Mars was incessantily debated over ,the argument concerning whether this planet witnessed the existence of organism which lives till now will be more fierce.

由于越来越多的证据表明红色行星上曾经含有大量稳定的液态水，由于人们对细菌化石是火星上的一块陨石带到地球上的这种观念争议不休，因此，有关该行星上是否曾经存在生命以及生命是否持续到今天的争论更加激烈。

She also said that the aerosphere around the earth is like a very thin egg shell,which suggests that the aerosphere is getting very fragile.

她还说：地球表面的大气层看起来就像一层很薄的鸡蛋壳。

Methods On the basis of a great deal empirical and calculated data, a fundamental calculating formula was derived to calculate cosmic radiation dose rate in aerosphere from sea level to altitude of 25 km.

在大量实验和计算数据的基础上，推导出计算从海平面至25 km高度地球大气层中任意位置宇宙辐射剂量率的基本计算公式。

Under the precondition of above analyses, this research compares the meteorite-stricken cases in planets and secondary planets of solar system, the "shielding" and "eroding" effect in aerosphere, the scale of small planets and movement rules, then briefly analyzes the basic reason of mass meteorite-stricken events occurred in earth history.

在上述分析的前提下，本研究从太阳系有关行星和卫星表面陨击现象对比，大气层的"遮蔽"和"侵蚀"作用，小行星的规模及运动规律等方面简要分析了地球历史上大规模陨击事件发生的基本原因。

Since the magnesium metal ions with gas phase state abundantly exist in the aerosphere of the earth and around the other planets, recently, there increasing attentions focused in Mg~+ and complexes related with Mg~+.

由于处于气相状态的金属Mg~+以令人惊讶的丰度存在于地球大气层和其它行星周围，近年来，人们对有关Mg~+及与Mg~+形成复合物的研究给予了越来越多的关注。

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。
