例句與造句
- The galaxy in the photo is m87 , a typical elliptical galaxy
：圖中的是m87星系，是一個(gè)典型的橢圓星系。 - Elliptical galaxies range in shape from almost perfect spheres to flattened globes
橢圓星系的外形范圍從幾乎完美的球體到壓扁的球。 - Elliptical galaxies do not take on the flat - disk or spiral shapes that most galaxies do
橢圓星系并不具有大多數(shù)星系具有的扁圓或是螺旋型的形狀。 - Spiral galaxies contain both young and old stars . in general , they are brighter than elliptical galaxies
：旋渦星系同時(shí)擁有年老和年青的恒星，它們通常比橢圓星系光。 - In the specific model we developed , elliptical galaxies have roughly equal numbers of each type
在我們所發(fā)展出的模型里，這兩類星團(tuán)在橢圓星系中的數(shù)量大致上是差不多的。 - It's difficult to find elliptical galaxy in a sentence. 用elliptical galaxy造句挺難的
- The light from an elliptical galaxy is brightest in the center and gradually becomes fainter toward its outer regions
從橢圓星系發(fā)出的光在中心部分最亮越靠近邊緣越暗淡。 - Taking the famous m87 elliptical galaxy as example , the dark matter in its core runs up to 2 . 4 billion solar masses
其中最著名的m87橢圓星系，其核心的黑暗質(zhì)量竟達(dá)24億太陽(yáng)質(zhì)量！ - As far as astronomers can determine , elliptical galaxies rotate much more slowly than spiral galaxies or not at all
直到天文學(xué)家能夠測(cè)定，橢圓星系自轉(zhuǎn)要比旋渦星系慢的多或者根本不旋轉(zhuǎn)。 - Elliptical galaxies have much less dust and gas than spiral galaxies have , and few new stars appear to be forming in them
橢圓星系中的氣體和塵埃比旋渦星系要少得多，貌似其內(nèi)部也少有恒星誕生。 - At least some elliptical galaxies , as well as the bulges and halos of spiral galaxies , may have arisen from such collisions
至少螺旋星系的核球與暈，以及某些橢圓星系，可能是由此種碰撞產(chǎn)生的。 - One way to demonstrate a link would be to identify two populations of globular clusters in old elliptical galaxies
要證明兩者彼此相關(guān)，其中一個(gè)方式，就是在古老的橢圓星系中，同時(shí)辨識(shí)出這兩類球狀星團(tuán)。 - Hubble space telescope image ? taken using only light that would be visible to the naked eye ? shows m87 [ lower right ] a giant elliptical galaxy
哈勃望遠(yuǎn)鏡捕捉到的這張照片顯示的是1999年1月23日伽馬射線爆炸的景象。 - A hubble space telescope image ? taken using only light that would be visible to the naked eye ? shows m87 [ lower right ] a giant elliptical galaxy
