建立了冲击压缩金刚石的光学反射率和透射率模型，并利用该模型计算了不同冲击压缩下金刚石的光学反射率和透射率。模拟结果表明，反射发生在激波前沿，与被压缩金刚石的厚度无关，但透过率随厚度的增加而减小。模拟得到的反射率与文献中的实验结果吻合较好，验证了模型的正确性。结果表明，当冲击波压力低于2.00Mbar时，金刚石保持透明；当冲击波压力从2.00 Mbar增加到4.60Mbar时，金刚石变得不透明但不反射探测激光；当冲击压力高于4.60Mbar时，金刚石对探测激光有明显的反射。
An optical reflectivity and transmissivity model for the shock-compressed diamond is established and used to calculate the optical reflectivity and transmissivity of the diamond under different shock compressions. The simulated results indicate that the reflection occurs at the shock front and does not depend on the thickness of the compressed diamond, but the transmissivity decreases with the thickness. The simulated reflectivity is consistent with the experimental results in the literature, which validates the model. It is shown that the diamond keeps transparent when the shock pressure is lower than 2.00 Mbar, and becomes opaque but does not reflect the probe laser as the shock pressure increases from 2.00 Mbar to 4.60 Mbar and reflects the probe laser markedly when the shock pressure is higher than 4.60 Mbar.
