The more strict equations of the GPS static absolute position are obtained,by considering the effect of the transmission of signal in earth's gravitation,on the condition that the earth's gravitation is static and spherically symmetric.

笔者认为导航卫星在地球周围的引力场中运行，因此要作精确的定位就必须考虑时空的弯曲结构对信号传播的影响，进而对GPS系统的静态绝对定位方程做出修正。1 GPS静态绝对定位原理如图1所示。

I know that each is a spheroid stars, the Earth and a lot of almost all large, have more than the Earth.

我知道每颗星都是一个球体，很多都和地球差不多大，还有比地球更大的。

Then, to incorporate non-linear earth pressure gradual change theory, to get non-linear earth pressure all spring elastic ground beam method which is related to wall deviation direction and magnitude.

然后结合非线性土压力渐变理论，得出非线性土压力全弹簧的弹性地基梁法，该法与墙体变位方向与大小均有关。

The records gathered revealed that these 90 initiates left their monastery in the inner earth and ventured up to a beautiful cave near the surface of the earth that was as large as a canyon with lakes, streams, waterfalls and stalactite ceilings that refracted the light of the aurora.

收集起来的记录揭示出，这90个提升者离开了他们地心的修道院，探访到一个靠近地表的优美洞穴中，这个洞穴巨大到就象一个包含湖泊、溪流、瀑布的峡谷，在钟乳石的洞顶上折射着地心极光的色彩。

Rare earth luminescence materials of alkaline earth stannates have also been prepared via thermal decomposition of hydroxo stannate precursors.

利用某些新型带羟基的碱土锡酸盐作为前驱体，固相反应合成掺稀土的锡酸盐发光材料。

If the brain is from the other star life , and the body is from human, then the cultural life of the brain has flooded the earth civilization, but the body, especially the sex demand are repelled by the earth civilization, this kind of behavior is evil and immoral.

倘若大脑是外星生命的，而身体是人类的，那么大脑的精神生活充斥了地球文明，而身体尤其是性需求却排斥在地球文明之外，这种行为也是邪恶的和不道德的。

Just as in astronomy the difficulty of admitting the motion of the earth lay in the immediate sensation of the earth's stationariness and of the planets' motion, so in history the difficulty of recognising the subjection of the personality to the laws of space and time and causation lies in the difficulty of surmounting the direct sensation of the independence of one's personality.

正如在天文学上，承认地球运行的困难乃在于否定地球不动而行星运动的直接感觉，在历史学上，承认个人服从空间，时间和因果关系的法则的困难，乃在于否定我们个人的独立性的直接感觉。

I can not negligent, he should do what?

我不能不在意了，他要做什么呢？

It is very dangerous to swim in the river alone.
