solar nebula 中文意思是什麼
solar nebula
解釋
太星-
Models of the solar system ' s early history posit that the frequency of impacts should have tapered off between 4. 5 billion and four billion years ago because most of the planetesimals ? the small rocky bodies that formed from the solar nebula ? were gradually cast out of the inner solar system or absorbed by the outer planets
描述太陽系早期歷史的模式假設，撞擊頻率應該在45 ~ 40億年前趨緩，因為大部份的微行星（由太陽星雲形成的小型石質天體）逐漸被驅逐出內太陽系或被外行星吸收。 -
It also appears to solve the deuterium problem but only if the rocky materials out near the earth ' s present orbit picked up some local water from the solar nebula ( the cloud of gas and dust surrounding the young sun ) before they accreted to form the earth
同時，看上去它也解決了氣含量的問題? ?但是只有當外來的巖石物質處于地球現今軌道附近時，並且在它們增生形成地球之前，從太陽的星雲里（圍繞著年輕太陽的氣體和塵埃）獲取了水時，這個問題才最終得到解決。 -
The minerals in these assemblages form at high temperatures, at least 1, 180 degrees c, so the refractory inclusions presumably date from the very beginning of the solar system ' s history, before the solar nebula cooled significantly
這些組合體內的礦物形成於非常高的溫度，至少約1180 ，因此耐火包體可能產生於太陽系歷史的最初期，在太陽星雲顯著冷卻之前。 -
Solar nebula theory
太陽星雲理論 -
Theorists figure a pre - solar nebula began to collapse about 5 billion years ago, possibly triggered by a shock wave from a nearby exploding star
前太陽星雲開始崩潰大約5十億年前的理論家形象，由沖擊波可能觸發從一個附近的爆炸的星。 -
According to common scientific wisdom, comets formed in the outer edges of the “ solar nebula, ” the swirling disk of gas and dust which gave birth to the solar system 4. 6 billion years ago
根據通常的科學常識，彗星都形成於「太陽星雲」 ? ?那個46億年前誕生了太陽系的氣體和塵埃盤，的邊緣地帶。 -
Some new laboratory studies of the manner in which deuterium gets exchanged between hydrogen gas and water vapor have indicated that the water vapor in the local region of the solar nebula would have had about the right proportion of deuterium to balance the excess deuterium seen in comets
最新的對于氫氣與水汽間氖交換方式的實驗室研究表明，處于太陽星雲里的水汽剛好有適當的氛含量來平衡彗星里所含的過多的氙。 -
To circumvent this problem, advocates of 26al heating hypothesize that some chondrules might have formed earlier in the solar system ' s history ? perhaps closer to the time when the minerals in the refractory inclusions condensed from the solar nebula ? and thus had much higher 26al to 27al ratios
為了解決這個問題，鋁26加熱說的擁護者假設，某些球粒可能是在太陽系歷史的更早期形成，也許與耐火包體開始由太陽系星雲的收縮而形成的時間差不多，因此鋁26對鋁27的比值較高。
