Stricklin was starting off in the hole, in what ejection - seat experts dispassionately call an " out - of - envelope situation with low survivability. " his plane was still falling fast, even after he managed to decrease the sink rate
可斯特里克林開始彈射的那個時刻，已經到了被彈射專家判定為「超出操控范圍的程度，生還機會極微」的節骨眼上。 -
According to the experimental data of droplet size 、 particle spectrum range 、 droplet cone shape 、 flow rate 、 cover area and cover area rate which obtained through changing the pressure of power sprayer and the nozzle diameter in greenhouse ， this paper made comparative analysis on atomizing performance in same pressure and different nozzle type between same nozzle type and different pressure. the conclusion is that : the ejection rate and the droplet cone shape change with the variation of pressure and nozzle diameter ， average particle diameter decreases obviously and particle quantity increases obviously with the increase of pressure and decrease of nozzle diameter. these results will lay experimental foundation for precise spraying 、 low pollution and highly effective operation
本文根據溫室內動力噴霧機壓力與噴嘴孔徑的變化影響霧滴大小、粒譜范圍、霧錐形狀、流量、覆蓋面積及覆蓋面積率的試驗數據，對相同壓力下不同噴嘴型號和相同噴嘴型號時壓力不同時的微粒化性能進行對比分析和研究，得到如下結論噴出量與霧錐形狀隨著壓力和噴嘴孔徑大小變化而變化；平均粒徑隨著壓力的增加和噴嘴孔徑的減小而明顯減小；粒數隨著壓力的增加和噴嘴孔徑的減小而明顯增多，為精噴量、低污染、高防效的防除作業奠定了實驗基礎。 -
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。 -
The predictive value of heart rate variability is independent of other noninvasive measures commonly used to predict prognosis of cardiac diseases, low left ventricular ejection fraction, and so on. like other risk predictors, measures of heart rate variability have modest positive predictive accuracy when used alone. however, combining measures of heart rate variability with other risk predictors yields a positive predictive accuracy of about 50 %
心率變異性的預測價值獨立於其他非創傷性預測心臟疾病預后指標（降低的左心室射血分數，頻發重復性室性心律失常等） ，在單獨應用時陽性預報率較低，但與其他指標聯合應用，陽性預報率可達50 。 -
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。 -
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。
