在冲击动压为133GPa的氧化铝单晶的冲击实验中，测量了在850nm处冲击氧化铝单晶的辐射曲线，发光信号显示被冲击压缩的单晶中存在延迟发射现象；该现象表明氧化铝单晶在冲击波到达后经历了一个再压缩过程，该过程可用失效波解释；通过实验曲线拟合到在133GPa下失效波的弛豫时间为0．107ms／cm．

The radiance curve of shocked alumina monocrystailine was measured with the radiation pyrom- eter. The experimental pressure is 133 GPa and the dxperimental wavelength is 850 nm. The recorded sig- nals reveal that there is a phenomenon of emission delay in the monocrystalline. It shows a failure wave has been formed in the shocked alumina monocrystalline, the fitted result based on the experimental data demonstrated the formation time of the failure wave in the shocked alumina monoerystalline is 0. 107 microsecond per centimeter.
