变晶的

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.
