The linear relationship between shock wave velocity d and particle velocity u of our samples were obtained : d = 3 . 701 + 1 . 527u there the unit of relocity is km / s . no phase transition shows for enstatite with perovskite structure according to the experimental linear d - u line up to 110gpa 实验结果表明,在80 115gpa压力范围内本文所用顽火辉石的冲击波速度d与粒子速度u可用线性关系: d = 3 . 247 + 1 . 626u来描述。
