adj.落下的

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。

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)氣體安定下來后，溫度必定降低。
