The research of this paper includes : ? high - speed photography and flash x - ray radiography are both used to capture the process of al shell ' s great deformation under low pressure. front illuminations are used to get the development of the fracture on the al shell. the relative energy release is analyzed from overpressure curves measured with some sensors
本文的研究內容主要包括: ?在受試炸藥經歷低應力大變形過程的susan試驗中,同時採用高速攝影、閃光x射線照相對彈體的撞靶過程進行了拍攝,得到了殼體膨脹變形過程圖像,並使用前照明技術觀察到了鋁殼表面產生的裂紋及其發展變化過程;從壓力傳感器測量的空氣沖擊波超壓曲線,獲得反應釋放總能。This observation is easily explained, if the universal expansion is accelerating : our motion away from the distant supernovae has speeded up since the light left them, sweeping us farther away than we would be in a universe with a constant or decelerating rate of expansion and hence a lower luminosity than expectation
這個觀測結果很容易以宇宙膨脹速度增加來解釋。假若宇宙的膨脹正在加速,那麼這些超新星遠離我們的速度將會不斷加大,它們和我們的距離當然會較膨脹速度不變或減慢的情況為遠,結果超新星的光度自然會較預期的暗。The initial evidence for acceleration came from the study of type ia supernova explosions, which in all cases reach a uniform or at least easily calibrated intrinsic luminosity
支持宇宙正在加速膨脹的第一個證據來自對ia型超新星的研究。這種超新星在爆發時,最終都會達致相同或至少容易校準的固有光度。
