A rocket is propelled by the ejection of a portion of its mass to the rear.
火箭是靠向後噴射其部分質量而推進的。 -
Solar activity, especially, coronal mass ejection ( cme ) during a large solar activity affected the space environment of human being and could be one of main reasons of the space disaster
太陽活動密切地影響著日地空間環境和地球高空大氣結構，太陽耀斑爆發產生的日冕物質拋射（ cme ）是空間災害的主要原因之一。 -
Wang, s., zheng, h. n. ， wang, x. h., 1997, magnetic reconnection and mechanism for the formation of coronal mass ejection in the coronal current sheets, research digest in memory of zhao jiuzhang, scientific press, beijing, 205

The turbulence picture predicts that whatever is true of low - mass stars should also be true of brown dwarfs, whereas the ejection hypothesis predicts that brown dwarfs will lose some of their starlike characteristics in the course of being ejected
亂流說預期低質量恆星與棕矮星的發生機制並無二致，排斥說則預言棕矮星在被排斥逐出的過程中會喪失某些恆星的特性。 -
Since sunspot number is closely related to solar activities like flares and coronal mass ejection, the sun might have entered a low - activity state for a rather long period of time during these minimums
由於太陽黑子數目與如耀斑和日冕拋射等太陽活動關系密切，在上述太陽黑子極小期內，太陽的活動可能沉寂了一段長時間。 -
Conventional two - dimensional echocardiography ( 2de ) provides a limited view of the lv and makes assumptions about its shape that may cause error in studying abnormal ventricles. three - dimensional echocardiography ( 3de ) can offer more diagnosing information than 2de, allow to view 3d lv from any position and orientation and be more accurate and reproducible than 2de in measuring lv volume, mass and ejection performance by avoiding geometric assumption
三維超聲心動圖可以獲得比二維超聲心動圖更多的診斷信息；允許從任意的角度觀察左心室三維形狀；在確定左心室體積、質量和射血功能時，不對左心室形狀做幾何假設，其測量結果更準確且可重復性好。 -
Results from this investigation show that the loss generation within the coolant holes is substantial and that ejection into regions of low static pressure increases the loss per unit coolant mass flow. the results also reveal strong interactions between endwall coolant ejection and secondary flow in the blade passage. the secondary flow has a strong influence on coolant trajectories and coolant ejection delays the three - dimensional separation of the inlet boundary layer on the endwall, chang the secondary flow and reduces its associated losses
本文的研究成果顯示，冷卻孔內產生的損失是主要的，並且低靜壓區域的冷空氣噴射會增加單位冷空氣質量流的消耗；噴射的冷空氣與葉柵端壁流場之間有強烈的相互作用；二次流對冷卻空氣的流動軌跡有較強的影響；冷空氣噴射能延緩端壁入口邊界層的三維分離、改變二次流從而減少其相關損耗。 -
Progress of a coronal mass ejection observed over an eight hour period on 5 - 6 august 1999
這六幀圖片捕捉了在1999年8月5日至6日期間，歷時8小時的日冕拋射現象。 -
After the process of matter ejection stellar body will continue collapsing into black hole if the mass of the nuclear - energy - exhausted star is more than 3 mq
星體經過物質拋射后，核能耗盡的恆星質量超過3m _ ，則此星體將繼續坍縮成黑洞。
