离子无序对主激波Hugoniot的影响
Effect of Ionic Disorder on the Principal Shock Hugoniot
摘要:
用多重散射理论研究了离子无序对超高压下主Hugoniot的影响。使用分子动力学模拟离子无序的计算,与那些具有固定的晶格,碳和铝。对于这里考虑的条件的范围内,我们发现,离子紊乱是最重要的壳层电离的发病,并在较高的压力,离子环境的微妙影响是压倒了大量的电离电子与较高的热能。
英文摘要:
The effect of ionic disorder on the principal Hugoniot is investigated using Multiple Scattering Theory to very high pressure (Gbar). Calculations using molecular dynamics to simulate ionic disorder, are compared to those with a fixed crystal lattice, for both carbon and aluminum. For the range of conditions considered here, we find that ionic disorder is most important at the onset of shell ionization and that at higher pressures, the subtle effect of the ionic environment is overwhelmed by the larger number of ionized electrons with higher thermal energies.
