引力

Now, the electromagnetic, the weak and the strong forces have already been unified in a quantum framework, whereas the quantization of gravitational field is still faced with the vital problem of infinities after more than 70 years of hard attempts.

爱因斯坦本人做了开创性的工作，即试图建立一个将引力和电磁力纳入同一理论框架的统一场论，但是虽然尽了后半生漫长而艰辛的努力，终未能成功。

The general effect is known as gravitational lensing, and this specific case is known as the Einstein Cross.

这种效应统称为引力透镜，而图上这种特殊的例子称为爱因斯坦十字。

This effect is known as gravitational lensing, and the heavy object that causes it as a gravitational lens.

这种效应就是引力透镜。大质量物体都能够形成这样的效应。

Because the gas cloud is more massive, the lensing it creates should be more pronounced.

由于气云较为庞大，所产生的引力透镜现象也就应该更为明显。

Another hallmark of dark matter is gravitational lensing, similar to the effect of light passing through a piece of polished glass.

暗物质的另一个特征是引力透镜现象，类似光线通过磨光玻璃时所产生的效果。

Hubble was used to map the dark matter using a technique known as gravitational lensing.

哈勃望远镜是用来绘制暗物质使用的技术，称为引力透镜。

Dr Clowe and his colleagues used a technique called gravitational lensing to detect the mass distribution of the bullet cluster.

克洛博士和他的同事使用一种叫做引力透镜的技术来探测子弹状星云团内物质的分布情况。

Dr Clowe and his colleagues used a technique called gravitational lensing to detect the mass distribution of the bullet cluster.

克洛韦博士及其同事们使用一种称为引力透镜（注1）的技术来探测子弹状星系团的质量分布情况。

In the first part of the thesis, the basic theory of gravitational lensing isintroduced, which includes strong lensing, weak lensing and microlensing,respectively, combined with their most recent observational results.

本文较详细介绍了引力透镜的基本原理，针对不同的情况、结合目前的观测结果对强透镜、弱透镜和微透镜分别作了系统的说明。

Ellis explains, Gravitational lensing is the magnification of distant sources by foreground structures.

Ellis 解释说：引力透镜效应是通过前景结构对遥远光源的放大的结果。

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.
