The MD (Molecular dynamics) method is used to investigate the he (Hydrogen Embrittlement) fracture of single-crystal and twin-crystal aluminum under tension.
采用分子动力学方法模拟了铝单晶、双晶及其含氢模型在拉伸条件下的力学特性。

The results indicate that a stable and suitable thermal field, the transparence of B_2O_3, doping quantity are important conditions for growth of twin-free InP crystal.
实验证明，建立一个稳定合适的热场、保持b_2o_3的透明度、控制好掺杂量等是减少孪晶的必要条件。

At the time of deformation reached 40%, the appearance of the crystal changed greatly: the size refined, boundary turned clear, second phase disappeared and twincrystal structure appeared.
