black hole mass

常見(jiàn)例句

Previous estimates of M87's black hole mass registered at some 3 billionsuns, still 1,000 times the size of the Milky Way's welterweight black hole.
原先估計(jì)M87星系的黑洞質(zhì)量為太陽(yáng)的3億倍，仍然相當(dāng)于銀河系次中量級(jí)黑洞的1000倍。
Most black hole mass seems to come from direct consumption (called accretion) of gas, indicating that a black hole needs a surrounding galaxy to grow.
大多數(shù)黑洞聚集物看起來(lái)是直接從氣體（叫做沖擊層）的消耗中間來(lái)的，這表明一個(gè)黑洞的成長(zhǎng)需要周圍有一個(gè)星系。
Eventually, like a ripening fruit, the galactic mass gets bigger until its ratio to the black hole mass gets to what astronomers have observed in nearby galaxies.
許多天文學(xué)家認(rèn)為，這個(gè)比率可以提供一個(gè)線索，透露出星系與黑洞形成的先后關(guān)系。
