球粒 的英文怎麼說

中文拼音 [qiúlì]
球粒 英文
chondrule
  • 球 : 名詞1 （以半圓的直徑為軸 使半圓旋轉一周而成的立體; 由中心到表面各點距離都相等的立體） sphere; glo...
  • 粒 : Ⅰ名 （小圓珠形或小碎塊形物） small particles; grain; granule; pellet Ⅱ量詞（用於粒狀物）
  1. 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。
  2. Through the spectrum analysis, the authors found that the microspherulites are mainly the lithical spherules, that is, the apatite and the siliceous spherules

    通過波譜分析，微球粒主要為石質球，即磷灰石球和硅質球。
  3. It was the study of chondrites that allowed researchers to work out how old the solar system is

    研究者通過研究球粒狀隕石而得出太陽系的年齡。
  4. To reach back, you need to look in the dust grains in chondrites, rather than at the chondrules

    如果是追溯太陽系形成之前，你需要研究球粒狀隕石中的灰塵顆粒，而不是隕石球粒。
  5. Chondrite normalized ree distribution patterns for the core q43 are comparable to those of the sediment of changjiang river and huanghe river delta

    球粒隕石標準化后的稀土元素具有與長江、黃河、黃土等上陸殼沉積物相一致的特徵。
  6. The average composition for our sample is different in some ways from the ci chondrite meteorites : namely we found more zinc, gallium, and copper, and less sulfur

    我們樣品的平均成分水平在某些方面與ci球粒隕石不同：即我們發現有較多的鋅、鎵和銅及較少的硫。
  7. Even after making generous assumptions, we determined that the maximum temperature reached in carbonaceous - chondrite asteroids with a diameter of 80 kilometers or more would be only 670 degrees c, too low to cause any melting at all

    即使給予很寬松的假設，我們認為直徑在80公里或以上的碳質球粒隕石小行星，達到的最高溫度只有670 ，不足以造成任何的熔化。
  8. Thermal models show that even if the asteroids assembled immediately after the formation of the chondrules, 26al heating would have raised temperatures in the interiors of ordinary - chondrite bodies to a maximum of 1, 100 degrees c ? high enough to cause melting of metals and sulfides but too low to melt silicate minerals extensively and differentiate an asteroid

    熱模型顯示，即使小行星在球粒形成之後立刻聚合，鋁26的加熱最多也只能將普通球粒隕石內的溫度提高到1100 ，雖可使金屬和硫化物熔化，但並不足以將矽酸鹽礦物大量熔化並造成小行星各層分異。
  9. Work out how old the oldest chondrules are, and you know when the sun ignited

    得出最老的隕石球粒的年齡，你就可以知道太陽是什麼時候開始燃燒的。
  10. That chondrules formed in such quantities suggests that the heating which created them was widespread

    這么大量的隕石球粒的形成說明能使它們形成的熱量的范圍很大。
  11. Looking at these isotopes allows the chondrules to be dated, and they were formed 4. 56 billion years ago

    觀察這些同位素可以估算出隕石球粒的年齡，他們是在45 . 6億年前形成的。
  12. 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。
  13. Although such hypothetical chondrules should have been preserved, researchers have not yet found any. ( to be fair, though, scientists have only just begun to look

    這種假設性的球粒應該能保存下來，但是研究人員至今仍尚未尋獲（不過，公平說來，科學家也才剛開始尋找而已） 。
  14. 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。
  15. 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） 。
  16. 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） 。
  17. White chromosphere one

    白色球粒
  18. Post - sintering test for uo and uo gdo nuclear fuel pellets

    Uo和uo gdo核燃料球粒后燒結試驗
  19. The southern hainan mafic dykes are strongly enriched in lile with high nb / ta ratios, indicating a magma source reconstructed by silicic - melt through partial melting of ancient subducted slides. however, the northern hainan mafic dykes with chondritic nb / ta ratio should be derived from the fiuid - metasomatized mantle related to ancient subduction zone

    瓊南基性巖脈強烈富k _ 2o等lile和具有較高nb ta比值，其地幔源區應受到了古俯沖板片部分熔融形成的硅質熔體的改造；而瓊中基性巖脈的nb ta比值接近於球粒隕石和morb值，應為古俯沖帶含水流體交代的地幔源區的產物。
  20. A few thin sections show fresh variolitic texture.

    少數薄片呈現新鮮的球粒結構。
