球石粒 的英文怎麼說
中文拼音 [qiúdànlì]
球石粒
英文
coccolith-
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。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。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。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。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。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。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。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。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。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。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。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） 。Of the eons of geological periods recorded in the stratifications of the earth : of the myriad minute entomological organic existences concealed in cavities of the earth, beneath removable stones, in hives and mounds, of microbes, germs, bacteria, bacilli, spermatozoa : of the incalculable trillions of billions of millions of imperceptible molecules contained by cohesion of molecular affinity in a single pinhead : of the universe of human serum constellated with red and white bodies, themselves universes of void space constellated with other bodies, each, in continuity, its universe of divisible component bodies of which each was again divisible in divisions of redivisible component bodies, dividends and divisors ever diminishing without actual division till, if the progress were carried far enough, nought nowhere was never reached
隱藏在大地的洞穴里和能移動的石頭底下蜂巢和土墩子中那無數微小的昆蟲類的有機生物：微生物病菌細菌桿菌精子憑著分子的親和之凝聚力而粘在一根針尖上那幾萬幾億幾兆個多不勝數肉眼看不到的微小顆粒人類的血漿是一個宇宙，群集著白血球和紅血球，每個血球又各自形成一個空虛的宇宙空間，群集著其他球體各個球體連續性地也是由可分割的構成體形成的宇宙，各個構成體又可以分割成為幾個能夠進一步分割的構成體。就這樣，分子與分母實際上在並未分割的情況下就不斷地減少了。如果這個過程延續到一定時候，就永遠在任何地方也不會達到零。Characteristic : shape of rose, specific design, jewelry could be stored in the corolla. there are many sparkle grains inlet on the petal would give the flickering effect
特色:玫瑰花形，款式獨特，可放首飾在花球內，花瓣鑲有多粒閃石，閃閃生輝，手工精緻。Lithogeochemistry and lithogenetic epoch for shaba granulite in mianning, sichuan
四川冕寧沙壩麻粒巖的巖石地球化學性質及形成時代The spherical particles are swept as droplets or volatilized and recondensed from a meteorite as it is heated to incandescence by friction in the upper atmosphere.
球形粒子是由小滴吹刮或者由在高層大氣中被摩擦加熱到白熾化的隕石揮發並重新凝結而成。According to sedimentary characteristics of the carboniferous taiyuan formation in feicheng coal field, including lithology, size distribution, sedimenta ry structure, geochemistry and paleontology etc., the carboniferous paleoenvironme nt of this area is divided into carbonate open platform and tidal flat environme nt. it is recognized that the taiyuan formation is formed in the epicontinental c oast which is dominated by the tidal. the peat flat is the important paleoenviron ment for coal accumulation. the tidal channel destroys the coal bed. the pulsative vibration of the crust is the major factor which controls the evolution of the sedimentary environment and the coal accumulation
根據肥城煤田石炭系太原組的巖性、粒度分佈、沉積構造、地球化學及古生物等沉積特徵，將該區晚石炭世古地理劃分為碳酸鹽開闊臺地和潮坪環境，認為太原組形成於潮汐作用為主的陸表海海岸，泥炭坪是成煤的重要古地理環境，潮渠對煤層有一定的破壞作用，地殼的脈動性振蕩作用是控制沉積環境演化和聚煤作用的主要因素。Finally, the application of the discrete element method with an interstitial fluid is discussed. for this purpose, a dynamic compacting process and a retaining wall problem are simulated by dem. it is shown that these problems can be qualitatively analyzed by dem
對存在填隙流體時離散元法的應用進行了初步探索，對塊石土強夯過程和擋土墻問題等進行了簡單的離散元模擬，可以看出採用存在填隙流體時球顆粒間的作用規律后，可以對一些問題定性分析。分享友人
