几年前，科学家就宣称发现了这两种元素，例如，1999年，俄罗斯物理学家用高能粒子钙- 48冲击钚- 244，产生了一个很快衰变的第114号元素的原子。
Evidence for the two elements has been mounting for years. In 1999, for example, Russian physicists bombarded plutonium-244 with calcium-48 to produce a single atom of rapidly decaying 114.
除了残骸，这些冲击波模型对于了解一系列天体物理学现象，从新恒星上的气体流动到恒星物质的喷发，有很重要的帮助。
Besides supernova remnants, these shock models are important in understanding a wide range of astrophysical phenomena, ranging from winds in newly-formed stars to cataclysmic stellar outbursts.
