| 1. | These particles constitute the cores of the interstellar dust grains that may be coated with ice . 这些粒子构成了星际尘埃颗粒的核子,这些尘埃颗粒的外面也许覆盖一层冰。 |
| 2. | To reach back , you need to look in the dust grains in chondrites , rather than at the chondrules 如果是追溯太阳系形成之前,你需要研究球粒状陨石中的灰尘颗粒,而不是陨石球粒。 |
| 3. | As a result , the automated scans will likely be flooded with false identifications , and the 40 or so actual interstellar dust grains may never be found 所以自动扫描将被洪水般的虚假判别所吞没,而这大约40个真正的微粒恐怕根本发现不了。 |
| 4. | Like the chondrules themselves , most dust grains were created in the early solar system ? in this case by bigger objects grinding against each other 和陨石球粒他们一样,大部分灰尘创造于太阳系初期? ?这样的话,它们是较大物体相互摩擦产生的。 |
| 5. | Researchers filled seven papers in the dec . 15 science with descriptions of just a tiny fraction of the roughly 10 , 000 dust grains captured 研究者在12月15日的《科学》杂志以七篇文章的篇幅描述了捕捉到的大约一万粒细尘中的很小一部分的情况。 |
| 6. | Two years later , in january 2006 , stardust returned these dust grains ? the first sample return from a solid solar - system body beyond the moon ? to earth 两年后的2006年1月,星尘号带回这些尘埃颗粒? ?首批带回的来自月-地系统之外的太阳系自身样品。 |
| 7. | Within days of arrival , mission scientists began extracting the dust grains from wild 2and preparing them for shipment to scientists around the world 在抵达后的数天里,任务科学家开始提取“怀尔特2 ”的尘埃颗粒,为世界各地的科学家准备研究材料。 |
| 8. | They did have one good lead to go on : when interstellar dust grains form in the cores of stars and are then ejected into space , they carry with them the signature of the event that produced them 科学家们确实寄希望于:当星际尘埃从恒星核心形成以及随后被抛入太空,携带着它们诞生时的信息。 |
| 9. | In many stellar disks , observers also have found the spectral signature of silicate emission , indicating that small dust grains on the disk surface have been strongly heated by the stellar radiation 天文学家也发现了许多恒星气盘具有矽的发射光谱,表示盘面上的微小尘埃颗粒已被恒星辐射强烈加热。 |
| 10. | If the rings persist then their supply of dust grains is being regularly replenished , and that almost certainly means that tiny moons within the rings are constantly shedding these particles 如果环是持久的,那么它们的尘埃就存在有规律的补给,这也就明确地意味着在环中的小卫星在不断的抖落这些颗粒。 |
