广义相对论

1960S, a student told me that he wanted to go into general relativity ratherthan the area I was working on, elementary particle physics, because the

生找我说，他想去做广义相对论领域的研究，而不愿意做我所在的领域－基本粒子物理学

In his early work on general relativity, Einstein realized that over cosmic distances space might not conform to the principles of euclidean geometry - that is, the sum of the angles of a very large triangle might not equal exactly 180

爱因斯坦在早期研究广义相对论时就已认识到，在宇宙规模的距离上，空间是不可能符合欧几里得几何的原理的，这就是说，一个非常大的三角形的内角之和不可能正好等于180度。

According to Albert Einstein's theory of general relativity , space around gravitational fields deviates from Euclidean space.

根据爱因斯坦的广义相对论，引力场的空间大约偏离欧几里德空间。

The study of extremal surfaces is of substantial interest in mathematics, general relativity and string theory.

极值曲面的研究在数学理论，广义相对论和弦理论中具有相当重要的地位。

In general relativity, time is considered a dimension like height, width and depth, creating a four dimensional universe called space-time.

在广义相对论中，时间被看作和长宽高一样的维度，并与它们构成了一个四维宇宙-被称作时空。

The modern study of space generalizes these ideas to include higher-dimensional geometry, non-Euclidean geometries (which play a central role in general relativity ) and topology .

现代的空间研究一般化了这些想法，包括高维几何，非欧几里德几何（这在广义相对论中发挥中心作用）和拓扑。

Geometry now is, in large part, the study of structures on manifolds that have a geometric meaning, in the sense of the principle of covariance that lies at the root of general relativity theory in theoretical physics.

现在是几何，在很大程度上是结构的研究流形上具有几何意义，在意义上的原则协在于从根本上广义相对论理论在理论物理。

This gives a much more geometrical and intuitive insight into vector and tensor calculus, together with general relativity, than do traditional, more abstract methods.

这给一更几何和直觉的对矢量和tensor微积分，以及广义相对论了解，比传统，更多的抽象的方法。

In fact, the situation can be described using the geometrical tools of general relativity.

事实上，这类情况可以用广义相对论的数学几何工具来描述。

According to general relativity, the observed gravitational attraction between masses results from the warping of space and time by those masses.

根据广义相对论，引力的观察结果与群众的翘曲的空间和时间的那些群众。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
