数十年来，天文学家们一度怀疑一种更寂静的恒星爆炸的存在——称之为“对不稳定”超新星，其能量超过普通超新星100倍。
For decades astronomers have suspected the existence of a type of stellar explosion that is bigger still-a "pair-instability" supernova, with 100 times more energy than an ordinary supernova.
通过净化介质可提高光学击穿阈值，进而提高相位共轭保真度、能量反射率及其稳定度等SBS特性。
By purifying the medium, the optical breakdown threshold can be increased; thus the phase-conjugation fidelity, the reflectivity of the energy and the stability of SBS increase correspondingly.
