We can get electron density with the calculated phase and some common model formula ( such as sphere and cone ) in the wake of hypervelocity projectiles
由計算出的相位並根據彈道靶尾跡的一些常用模型（包括圓球體、鈍錐體等）公式，把相位轉化為尾跡的電子密度。Their full slow eyes belied the words, the gestures eager and unoffending, but knew the rancours massed about them and knew their zeal was vain. vain patience to heap and hoard
他們那睜得圓圓的滯鈍的眼睛，與這些言談，這些殷切不沖撞人的舉止相左，然而他們曉得自己周圍積怨甚深，明白一腔熱忱是徒然的。In time of use of this product, it is only required to make hanging rope cross above solid structural object with truncated edge, hang ring - shaped hook on hanging rope inside the upper interface and circular ring of anti - dropping device, and then hang the ring - shaped hook of roll - up safety belt inside the semi - circle ring on safety belt
使用時只需將懸掛繩跨過上方堅固鈍邊的結構物上，將懸掛繩上的環形鉤掛入防墜器的上部介面和圓環，將卷收安全帶的環形鉤掛入安全帶上的半圓環內即可使用。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 results show that, after transformation the size, shape and distribution of primary silicon in hypereutectic al - si alloy have a serious effect on the tool life and the machined surface quality of the alloy, the alloy whose primary silicon is fine, spread and dull angular has a better machinability
試驗結果表明：過共晶鋁硅合金經變質處理后組織中初晶硅的大小、形狀和分佈狀況對切削刀具壽命和合金的切削加工表面質量影響極大，具有細小、分散而形狀圓鈍化初晶硅的合金有比較好的切削性能。分享友人
