The glass with a higher length-to-diameter ratio was formed under lower temperatures and speed when a meteorite impacted the lunar surface, reflecting milder impact events compared with the formation of glass beads which have a lower length-to-diameter ratio.

陨石撞击月球表时，在较低温度和速度下形成了长径比较高天然玻璃纤维，与具有较低长径比玻璃珠形成相比，这反映了月球表较为温和微撞击事件。

Some have the regular glass beads on them, and other ones have the 3M elements on them with the 1.9 refractive index or the 2.4 refractive index or a combination of those.

有上有通玻璃珠，有上有折射率为 1.9 或 2.4 3M 元件，或者是它们组合。

For example if you were very wealthy, you may wear emerald, but if you were less wealthy you might wear green glass beads instead.

例，果你非常富有，你可能会戴祖母绿，但果你不那么富有，你可能会戴绿色玻璃珠。

The water is in extremely small glass beads that were found in the dirt where many meteorites have hit the moon. The dirt was collected in 2020.

水存在于极小玻璃珠中，这些玻璃珠是在月球被许多陨石撞击时产壤中发现。这些壤是在2020年收集。

And NASA says that detected water that's trapped in glass beads or in between grains on certain parts of the moon.

美国宇航局表示，探测到水存在于玻璃珠或月球上某些固体颗粒中。

Scientists analyzed 117 glass beads which were scooped up by the Chang'e-5 spacecraft and selected 32 homogeneous impact glass beads for further detailed analysis.

科学家们分析了嫦娥五号飞船收集到 117 颗玻璃珠，并选择了 32 颗均匀撞击玻璃珠进行进一步详细分析。

Since billions if not trillions of these beads exist on the moon, there could be large amounts of water.

由于月球上有数十亿颗甚至数万亿颗这样玻璃珠，所以月球上可能存在大量水。

The amount of water inside was extremely small.

玻璃珠里水量非常少。

" That's equivalent to half a kilogram of water inside a tonne of impacting glass beads, more than we previously thought, " Hui Hejiu, co-corresponding author of the study, told Science and Technology Daily.

“这相当于一吨撞击玻璃珠里有半公斤水，比我们以前想象要多，”该研究共同通讯作者惠鹤九告诉《科技日报》。

The material, which includes spherical, ellipsoidal, and dumbbell-shaped glass beads as well as colloidal items with a porous structure and sputtering material in fluid form, have also been found.

此外，还发现了球状、椭球状、哑铃状等形状玻璃珠，以及气孔构造胶结质和流体形态溅射物。

Hui said the beads differ in size from the width of one hair to several hairs. The amount of water inside was extremely small.

惠鹤九说，玻璃珠大小不一，有玻璃珠直径和一根头发一样粗，有直径宽度有几根头发粗。玻璃珠里水量非常少。

They first used these glass beads.

他们首次使用了这些玻璃珠。

" Yes, it will require lots and lots of glass beads, " Hui said in an email. " On the other hand, there are lots and lots of beads on the moon."

惠教授在一封电子邮件中说：“是，这需要很多很多玻璃珠，但从另一方说，月球上有很多很多玻璃珠。”

Led by the Chinese Academy of Sciences, the study suggests that " impact glass beads in lunar soils are a prime water reservoir candidate able to drive the lunar surface water cycle."

由中国科学院牵头研究表明，“月球壤中冲击玻璃珠是能够驱动月球表水循环主要候选水库。”

The findings are based on 32 glass beads randomly chosen from moon dirt collected on China's Chang'e 5 moon mission.

这些发现是基于从中国嫦娥五号任务中收集月球壤中随机选择32颗玻璃珠。

Since billions if not trillions of these beads exist on the moon, there could be large amounts of water. But mining it would be difficult, the research team said.

由于月球上有数十亿颗甚至数万亿颗这样玻璃珠，所以月球上可能存在大量水。但该研究小组表示，开采它会很困难。

The study's findings raise the possibility that water could be removed by heating the beads in future robotic missions.

这项研究发现提高了在未来机器人任务中通过加热玻璃珠来去除水分可能性。

They found an average water content of 0.05 percent in the glass beads, the Science and Technology Daily reported.

据《科技日报》报道，他们发现玻璃珠平均含水量为 0.05%。

" On the other hand, there are lots and lots of beads on the moon."

“另一方，月球上有很多很多玻璃珠。”

Earlier studies found water in glass beads formed by volcanic activity on the moon. Those studies used material collected on the moon by American astronauts more than fifty years ago.

早期研究发现，月球上火山活动形成玻璃珠中含有水。这些研究使用了50多年前美国宇航员在月球上收集材料。
