Because accretion disks also contain flows with very high rates of shear , scientists proposed in the 1970s that the disks must also be highly turbulent 因為吸積盤也包含具有非常高切變率的流體,科學家在1970年代倡議吸積盤必定非常混亂。

That cold accretion called the world , which , so terrible in the mass , is so unformidable , even pitiable , in its units ( thomas hardy 那個被稱為地球的沖積而成的寒冷球體,整體是如此令人生懼,各部分又是那么懦弱甚至令人生憐(托馬斯?哈代) 。

With the increase of the velocity and acceleration of the moving target , it produces a large accretion of dynamic error of o - e theodolite 隨著被測目標運動速度和加速度的不斷提高,導致光電經緯儀電視跟蹤的動態誤差急劇增大。

Although turbulence is sometimes seen in these experiments , it may arise from effects that would not be present in a real accretion disk 雖然有時在這些實驗中可看見亂流,但那可能源自某些不會出現在真實吸積盤中的效應。

Investigators have conducted laboratory experiments to search for turbulence in flows that resemble accretion disks , but again the results have been debated 研究人員也做實驗尋找像吸積盤般流動的亂流,而結果仍有爭論。

Although it becomes invisible past a certain point , an accretion disk , which is visible , develops as the matter swirls toward the black hole 雖然它變成看不見的過去某點,一個增大圓盤,是可見的,當物質向黑洞成漩渦發展。

Then , we analyse in detail the mass - accretion histories and structural properties of dark haloes in high - resolution n - body simulations 本文利用高分辨率的n體數值模擬仔細分析了暗暈的質量吸積歷史和內部結構演化歷史。

Astronomers ascribed them to thermonuclear fusion of hydrogen or helium or to the sudden accretion of matter onto the star 天文學家因此可將其歸因于氫或氦的熱核融合反應,或是有物質突然被星體吸附而產生的。

Later simulations show that even a companion with an orbit as wide as neptune ' s could scoop up an accretion disk 后來的數值模擬結果顯示出,即使伴星的軌道半徑大如海王星的軌道,它仍可汲取物質而形成吸積盤。

Astronomers all along rely on radiation emitted from accretion disk of binary as the only clue for detection of black holes 天文學家一直依賴黑洞吸食物質時所發出的輻射,作為探測黑洞的唯一線索。

Several items on our list have come about because of the slow , steady accretion of basic research findings and trial results 有幾個故事是基于一些緩慢的、逐步累積的關于基礎研究以及試驗的進展。

If its process of accretion is never halted , if the balancing stage is never reached , there will be no toppling 倘若財產的增長過程從未中斷過,倘若那種平衡的狀態從未達到過,那么就不會垮掉。

Ghoramara island has lost 75 % of its land area in last 30 years due to heavy erosion and slow rate of accretion 哥若馬若島30年來,因為大量的侵蝕,和慢速度的沖積,已喪失了三分之二的土地。

Accretion disks formed when compact objects suck in matters of companion stars may also betray the existence of black holes 另一個重要的觀測對象是致密天體因為吸食伴星物質而形成的吸積盤。

And astronomers , in fact , have seen evidence of spiral - wave patterns in accretion disks in some binary systems 事實上天文學家已在一些雙星系統的吸積盤中,看見螺旋波圖樣的證據。

Nevertheless , astrophysicists have persisted in their belief that accretion disks are indeed turbulent 雖然如此,天文物理學家仍舊堅持信念,認為吸積盤的確是充滿亂流擾動的。

But what is the nature of the friction inside the accretion disks that touches off this enormous energy release 然而,引發吸積盤內巨大能量釋放的摩擦,本質是什麼?

Unfortunately , this simple process cannot explain the activity of many other types of accretion disks 很不幸地,這個簡單的程序無法解釋許多其他型態的吸積盤活動。
