一個同蘇聯結盟的河內統治下的印度支那；它是由於一個遲鈍的超級大國不願給自己的外交一個取勝的機會而造成的。The tests were conducted in the hypersonic low density wind tunnel at nominal test conditions of mach 16, stagnation temperature 923k, stagnation pressure 1. 40mpa and 7. 30mpa. heat - transfer data were obtained on a hemisphere model, a sharp cone and a big blunt cone respectively by means of infrared thermal mapping techniques, that of a 0. 5mm thickness blunt cone by virtues of thermocouples. furth ermore, heat - transfer on all those models was calculated with the theoretical method
最後在名義m _ = 16 、 t _ 0 = 923k 、 p _ 0 = 1 . 40mpa及7 . 30mpa的高超聲速低密度風洞中，利用紅外熱圖技術獲得了半球圓柱、尖錐、大鈍頭三個模型表面熱流分佈，利用薄壁法技術得到了一壁厚為0 . 5mm的鈍錐模型表面的熱流分佈，並通過工程理論方法計算了模型表面的氣動熱，把理論計算結果與上述試驗結果比較，幾者符合得較好。The flowfields around the reentry blunt body are simulated numerically by solving the navier - stokes with the various thermal and chemical model, such as perfect gas model, vibrational excitation model, equilibrium gas model, and the non - equilibrium gas model of one temperature, two temperature and three temperature
本文採用完全氣體模型、振動激發氣體模型、平衡氣體模型、一溫度非平衡氣體模型、兩溫度非平衡氣體模型和三溫度非平衡氣體模型進行了鈍體高超聲速繞流流場的數值計算。Both hydrogen plasma and sinx thin film can effectively enhance the short circuit current density of mono and poly silicon solar cells, which cause the improvement of the absolute transfer efficiency about 0. 5 % ~ 2. 9 %. depositing sinx thin film followed by hydrogen plasma treatment will result in better passivation effect. the thickness of sinx thin film will decrease and the refractive index will increase after annealing
經過薄膜後退火處理發現，氮化硅薄膜經熱處理后厚度降低，折射率升高，但溫度達到1000oc時折射率急劇降低；沉積氨化硅薄膜后400oc退火可以促進氫擴散，提高鈍化效果；超過400oc后氫開始逸失，晶體硅材料中的少子壽命急劇下降； rtp （快速熱處理）處理所導致氫的逸失比常規退火處理顯著。Latapy, who will be 38 in august, and currently plays with falkirk in the scottish premier league, admits he has lost some speed but not his knowledge of the game
今年8月就38歲的拉塔皮目前是蘇格蘭超級聯賽隊福爾柯克隊的球員。他說他承認他的速度有所減退，但對比賽的感覺絲毫沒有遲鈍。分享友人
