球粒體 的英文怎麼說
中文拼音 [qiúlìtǐ]
球粒體
英文
sphaeroplast-
According to this scenario, researchers could never find evidence of such early chondrules because all these objects would have been destroyed by the melting of the chondritic asteroids into which they accreted
在這個情形下,研究人員恐怕永遠也無法找到如此早期的球粒證據,因為所有這些物體在聚合的過程中,都會因為球粒隕石小行星熔化而被破壞。Like the chondrules themselves, most dust grains were created in the early solar system ? in this case by bigger objects grinding against each other
和隕石球粒他們一樣,大部分灰塵創造于太陽系初期? ?這樣的話,它們是較大物體相互摩擦產生的。Because the chondritic asteroids formed after the chondrules did, the initial 26al to 27al ratio in chondrules places an upper limit on the amount of 26al that was available to heat the rocky bodies
因為球粒隕石小行星是在球粒之後形成,球粒中鋁26對鋁27的初始比值,決定了能夠用來加熱石質天體的鋁26含量的上限。These investigations have found strong evidence for the former presence of 26al in the so - called refractory inclusions : tiny mineral assemblages, rich in calcium and aluminum, embedded in chondritic meteorites alongside the chondrules
這些研究發現了強而有力的證據,顯示鋁26曾經存在於所謂的耐火包體(富含鈣和鋁的細小礦物組合體,與球粒一起鑲埋在球粒隕石內) 。Given the decay rate of 26al, the lower initial ratio in the chondrules implies that these objects formed between one million and two million years after the creation of the refractory inclusions ( assuming that the radioisotope was indeed homogeneously distributed in the early solar system )
以鋁26的衰變速率估計,這些球粒的初始比值較低,表示它們是在耐火包體產生后100 ~ 200萬年才形成(假設鋁26在早期太陽系中確實是均勻分佈的) 。In one, equiaxed dendrites form and subsequently ripen into more - or - less spheroidal shape, suitable for forming

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。分享友人
