摘要： Using uniform illumination of high-power laser on targets and the principle of impedance-match, the shock wave velocities in the standard material and the test sample have been measured experimentally on "Shenguang-I" laser facility from high-quality luminant signals produced at the back surface of target, and the shock adiabats of Fe and SiO2 were obtained, respectively, in the pressure ranges of 0.35-0.82 and 0.21-0.41 TPa.
