查询词典 gravitational lens

56 We shave it off, and I have a little gravitational lens, OK.

我们把它剃掉，然后我就有了一个引力透镜

One might say that the cluster has acted like a giant magnifying glass, or gravitational lens, in space — focusing, magnifying and distorting the images of the galaxy.

可以说，集群已采取行动，像一个巨大的放大镜，或重力透镜，在太空-聚焦，放大和歪曲的形象银河。

For fiatΛCDM cosmogonies withσ8 normalized by recent weak gravitational lens-ing observations, the best results are obtained forΩ0～0.3;Ω0≤0.2 leads to too large galaxy correlation lengths, whileΩ0≥0.4 gives too high mass-to-light ratios to match the observed TF relation.

对于平直ACDM宇宙学模型，根据最近的弱引力透镜给出的σ8值，条件光度函数模型给出了最佳值为Ω0～0.3；当Ω0≤0.2时，星系相关长度过大；而Ω0≥0.4则给出了太高的质光比，和观测的TF关系不符合。

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。

The object's gravitational field will bend the starlight like a lens, briefly making the star appear slightly brighter.

它的引力场会像透镜一样弯折光线，使星体暂时变得稍微明亮些。

This natural telescope is a gravitational lens.

这个天文的望远镜就是引力透镜。
