The phase structural change withtemperature of solid helium is also studied using MD simulation at a givendensity 1.6g/cm3.Radial distribution functioncalculation demonstratesthat its second peak will disappear beginning in the region from 2000K to3040K,showing a solid-liquid transition or a decrystallization occurs.

文中进一步用分子动力学方法研究了在固定ρ＝1.60g/cm3下固氦相结构随温度的变化，发现其径向分布函数的第二个峰在2000K到3040K区间及其以后逐步消失，意味着此时发生了一次固-液相变或非晶化过程。

Helium is inert, which removes all risk of flammability, both real and perceived.
