采用分子动力学方法结合对关联函数分析计算了0—1000 K范围内氦的固—液相变曲线,与实验数据的对比显示,在0—500 K之间与实验数据符合很好,500 K以上还没有相应的实验数据.另外,计算了钛金属中不同尺寸氦泡的压强,并与高密度氦的固—液相变曲线进行了对比.结果显示,在低温条件下,随着温度的降低,钛晶体中可能会出现固态氦泡;在300 K以上不会存在固态氦泡. The molecular dynamics method and the correlation function analysis were used to calculate the solid-liquid phase transition curve of helium in the range of 0-1000 K. Comparing with the experimental data, it is in good agreement with the experimental data from 0 to 500 K and 500 K In the above, there is no corresponding experimental data.In addition, the pressure of helium bubbles with different sizes in titanium is calculated and compared with the solid-liquid phase transition curves of high-density helium.The results show that under the condition of low temperature, Lower, solid helium bubbles may form in the titanium crystal; solid helium bubbles do not exist above 300 K.
