围绕地球的

The Soviets had much more thrust power; they launched the first inhabited capsule with a dog in it,and then in 1961 made Cosmonaut Yuri Gagarin the first human to orbit the earth.

苏联当时有更强大的推动力，他们首次发射了载有一只狗的太空舱，然后在1961年，让宇航员Yuri Gagarin 成为第一个围绕地球轨道飞行的人。

This dissertation focuses on the spherical wavelet expansion of the earth gravity field and its application. Based on the concept of the integration approaches and radial basis functions the spherical wavelet is put forward, with that the earth gravity field is described in a new way, and some other researches are conducted, they are: spherical wavelet regularization, multiscale approximation of satellite gravity measurement, down continuation of airborne geavimetry data, the least squares properties of geopotential wavelet approximation, the spherical wavelet solution of two kinds of BVP and spherical selective multiscale reconstruction.

本文围绕地球重力场的球面小波展开及其应用进行研究，在积分逼近与径向基函数概念的基础上引入了球面小波，利用球面小波对重力场展开进行了重新表示，在此基础上进行了球面小波正则化、卫星重力多尺度逼近、航空重力数据向下延拓、重力场球面小波逼近的最小范数性质、两类边值问题的球面小波实用解、球面选择多尺度去噪方法等方面的研究。

It is strange that the earth is round and the orbit it moves round the sun is a circle.

很奇怪地球是圆的，它围绕太阳的轨道也是圆的。

Over break 3. But even assuming that a planet is the right size and has the proper chemical composition and a stable orbit neither too far from its star nor too close, so that its temperature is at all times in the range of liquid water (as is true of Earth except for the polar regions), a great deal would stilldepend on the kind of star it was revolving about.

over break 但是即使假定有一颗行星，它的大小正好，化学成分适宜，运行轨道稳定，与恒星的距离既不太远也不太近，气温始终保持在液态水温的范围内（正如地球上极地以外地区的温度一样），那儿是否存在生命，在很大程度上仍得取决于它所围绕运转的是什么样的恒星。

Neo Matrix 3D screensaver brings your consciousness to the higher levels of reality where you can find yourself in the endless pseudo matrix 3D alien tunnels spinning and wirling around to change your perception of the earth environment.

新矩阵三维屏幕保护程序将你的意识的更高水平的现实在这里您可以找到自己在无休止的伪三维矩阵外来隧道纺纱和wirling围绕您的看法改变了地球的环境。

According to many Earth legends, the Zep Tepi are supposed to return regularly, at the beginning and end of each time cycle, the 13,000 year half-point of our solar system - 26,000 year zodiacal orbit around galaxy center.

根据很多地球的传说，Zep Tepi假定有规律地返回，在每个周期的开端和结束时，13，000的年一半-我们的太阳系的点-26，000年围绕银河中心的黄道带轨道。

Some of these chemicals are thought to have come from a planet-forming disk of gas and dust that swirled around our young sun. Meteorites carrying the chemicals might have crash-landed on Earth.

部分有机物被认为来自围绕我们原始太阳的原始行星盘中的气体和尘埃，落在地球的陨石群带来另外一些有机物。

Actually, where our Earth orbits, outer space is far from empty.

实际上，我们的地球围绕着的转的太空可不真的是空的。

The idea was two decades ahead of its time, and helped to attach his name to the geostationary orbit above the equator. In 1962, at the chilliest part of the cold war and just after the launch of Sputnik had heralded the space age, he discussed in "Profiles of the Future" the implications of transatlantic satellite radio and television broadcasts, with information raining down on previously isolated parts of the world.

他在20年前就萌发了这个想法，也是这个想法让他把名字贴到了围绕赤道的地球同步轨道上。1962年，也就是爆发冷战最严重的那一年，继Sputnik 人造卫星的成功发送开启了太空世纪后不久，他在《未来的轮廓》一书中探讨了卫星广播和电视广播横渡大西洋的应用，他认为它们将使信息降落到原先与世隔绝的那些地方。

We see the change from new moon to quarter to full and back to new moon every twenty-eight days.

我们称此时的月亮叫做半月；有时，向阳的一面背向我们，则仅见一边的边缘透过一丝银光。我们称之为新月；月球围绕地球一周需28天。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
