摘要: 从氢原子间及氢分子间的相互作用入手,提出了固体氢中氢分子在高压作用下解离为氢原子,并以氢原子相互结合成金属氢的微观转化过程的机理。用这样的转化机理,可以解释毛河光等关于固体氢的拉曼光谱频率随高压变化规律的实验结果。Abstract: A mechanism for the metallization of solid hydrogen under high pressure is proposed on the basis of the theoretical analysis on the structural change of hydrogen molecule in solid state at high pressures. The experimental results from H. K. Mao, et al., about the Raman shifts of solid hydrogen under pressure, may be explained reasonably by the proposed mechanism.
