13. As the accretion disk feeds more mass into itself, the embryo star contracts, growing ever denser and more massive.
隨著吸積盤獲得越來越多的物質(zhì)，胚胎恒星就不斷收縮，密度和質(zhì)量都變得越來越大。
14. In chapter three, on the basis of the new anomalous magnetic Prandtl number in accretion disks, we study the effect of dissipation on magnetic instability of Keplerian disks.
第三章在新的反常磁普朗特數(shù)的基礎(chǔ)上，我們研究了耗散過程對開普勒盤磁不穩(wěn)定性的影響。
15. It deduces from the results of calculation that the maximal contact stress have a obvious accretion at the hurt spot, the quantity is maybe 1.5 times than the normal state. But the bend stress almost the same.
從齒輪損傷后的計算結(jié)果得出：齒輪損傷處的接觸應(yīng)力最大值有明顯的躍遷，躍遷值大約是未損傷的1.5倍，但齒輪的彎曲應(yīng)力沒有多大變化。
16. Aircraft can experience icing when encountering a cloud that contains supercooled water droplets. Ice accretion is a common phenomenon in flight. It is one of the main hazards to flying.
飛機積冰是飛機在積冰氣象條件下飛行時，大氣中的液態(tài)水在部件表面凍結(jié)并累積成冰的一種物理過程，是飛行實踐中廣泛存在的一種現(xiàn)象，也是導(dǎo)致飛行安全事故的主要隱患。
17. Terrain heightened can enhance blocking effect, which lead to strengthen water vapor flux divergence and vertical convection, and cloud water increases but centralizes in the middle-low level. This change intensify accretion of snow by collecting more supercooled cloud water, and rain water converts into graupel by collecting more snow, and dry growth of graupel increase at the same time. Rain water augment because of more graupel melting, and rain water continue to increase by collecting cloud water in the low level.
地形高度增加后，阻擋作用加強，使水汽通量輻合加強，垂直氣流增大，中低層云水增多，導(dǎo)致雪撞凍過冷云水增多，促使了雨水撞凍雪轉(zhuǎn)化為霰和霰干增長過程的加強，霰融化為雨水增多，低層雨水碰并云水加強，冷云過程得到增強。
18. The results show that the system can keep certain smoothness with short delay, but the control precision can decline with the accretion of time delay, long random delay will not only reduce system expeditiousness, but also the smoothness and control precision at the same time. If the random delay is long enough, it can destroy the stability of networked control systems.
研究結(jié)果表明：系統(tǒng)在較小的延時下仍能保持一定的穩(wěn)定，隨著延時的增大，系統(tǒng)的控制精度有所降低；而較大的隨機延時不但降低系統(tǒng)的總體快速性，同時，使系統(tǒng)的穩(wěn)定性和控制精度明顯降低，而當(dāng)隨機延時大到一定程度時，系統(tǒng)的穩(wěn)定性難以保證。
19. Sediment accretion. Changes in community structure over time are apparent from pollen analysis of sediment cores.
群落結(jié)構(gòu)隨時間的變化從沉積物芯樣的花粉分析來看是十分明顯的。
accretion的反義詞
20. This paper focuses on the application of hydrodynamics and magnetohydrodynamics to solar oscillations and accretion process and outflow in star formation.
本文著重討論了流體和磁流體力學(xué)在日震學(xué)方面和恒星形成中吸積和外流這兩方面的應(yīng)用。
