查询词典 galaxies

Foucault's pendulum, and other much more sensitive experiments, demonstrate that an inertial frame is also one in which the distant galaxies do not appear to rotate.

一节，我们介绍了惯性系的概念：找一个参考系使牛顿定律适用于傅科摆和其他更敏感的实验，而我们发现在这个惯性系中遥远星系是不转动的。

To explain why the frame of the distant galaxies is an inertial frame, we really need either Mach's principle or another postulate.

为了解释遥远星系参考系是惯性系，我们要么需要马赫原理，要么需要其他什么假定。

The surprise is that we are seeing dust hundreds of thousands of light years outside of the galaxies – in intergalactic space.

意外的是我们在距离星系数十万光年的星系际空间观察到了尘埃。

All matter and energy, including Earth, the galaxies and all therein, and the contents of intergalactic space, regarded as a whole .

宇宙一切物质和能量，包括被视为一个整体的地球，各星系及其所包容的星体，和星系间空间电的物质

Location of the planetary nebulae in the outskirts of the giant galaxy Messier 87 and in the intergalactic space around the centre of the Virgo Cluster of galaxies.

图中标出了位于巨椭圆星系M87外晕远处的和位于室女座星系团中心的星系间空间中的行星状星云。

The team used FLAMES, the super-efficient spectrograph at ESO's Very Large Telescope at the Paranal Observatory in Chile, to make ultra-precise measurements of a host of planetary nebulae in the outskirts of Messier 87 and in the intergalactic space within the Virgo Cluster of galaxies, to which Messier 87 belongs.

研究团队使用FLAMES——VLT阵列中的超高效摄谱仪，极为精确的测量了M87外缘和室女座星系团星系间空间中的行星状星云。

The movement of internal energy comes from, the black hole for stars, galaxies movement of energy.

人的运动能量来源于内部，因此黑洞也为恒星，星系的运动提供能量。

The effect is further enhanced in this well-framed view by the galaxies that lie beyond this gorgeous island universe.

这个效果进一步被存在于这个灿烂的岛宇宙之外的星系的充分限定的视野加强。

Some cosmologists think this expansion will leave the Milky Way galaxy as an "island universe" in a few trillion years with no other galaxies visible.

一些宇宙学家认为这种膨胀将使得银河系在接下来的几万亿年里变成一个宇宙岛并且将没有其它可见的星系。

Although cold dark matter has its own problems in explaining cosmic structures [see "The Life Cycle of Galaxies" by Guinevere Kauffmann and Frank van den Bosch; Scientific American, June 2002], most cosmologists consider these problems minor compared with the difficulties faced by alternative hypotheses.

虽然冷暗物质在解释宇宙结构上也有它自身的问题（见《科学人》2002年8月号〈星系传奇〉），但大多数宇宙学家认为，较诸其他假说所面对的困难，这些问题可说是次要的。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
