常見(jiàn)例句A companion star is a perfect source of infalling material for a black hole. 伴星是物質(zhì)下陷形成黑洞的一個(gè)極好的物質(zhì)來(lái)源。As the white dwarf spins, the columns of infalling gas rotate with it. 當(dāng)白矮星自轉(zhuǎn)時(shí)，被吸入的氣柱也跟著一起轉(zhuǎn)起來(lái)。As the infalling matter approached the center, it reached higher and higher densities. 當(dāng)墜入的物質(zhì)接近中心時(shí)，它的密度會(huì)越來(lái)越高。Intriguingly, they found that layers of infalling matter could intersect to create momentary singularities that were not covered by horizons. 非常有趣的是，他們發(fā)現(xiàn)密度不同的各層物質(zhì)在坍塌時(shí)，彼此會(huì)有交互作用而短暫地產(chǎn)生不被視界遮蔽的奇異點(diǎn)。The annihilation of the infalling photon acts as a measurement, transferring the information contained in the matter to the outgoing Hawking radiation. 向內(nèi)墜落的光子，其毀滅的過(guò)程就是個(gè)測(cè)量的動(dòng)作，會(huì)將黑洞內(nèi)物質(zhì)的資訊轉(zhuǎn)移給向外發(fā)出的霍金輻射。An embryo's gravity pulls in gas from the disk, but the infalling gas releases energy and must cool off if it is to settle down. 行星胚胎的重力會(huì)從氣盤(pán)吸引氣體，但墜落的氣體會(huì)釋放能量，所以當(dāng)氣體安定下來(lái)后，溫度必定降低。 返回 infalling
