本文通过静态样品定标的方法，在神光Ⅱ实验装置上获得了给定空间频率下分幅相机系统的调制传递函数．在相同实验配置的情况下，利用定标的结果，实现了对正弦扰动样品的流体力学不稳定性增长的绝对测量，获得了不同时刻的增长因子，结果表明现阶段己具备辐射驱动流体力学不稳定性实验的扰动增长表征能力．

英文摘要：

In inertial confinement fusion experiments, the measurement of hydrodynamic instability growth factor is an important means of studying hydrodynamic instability. In this paper we use the calibration of the sample to gain the modulation transfer function of framing camera at a given space frequency. The calibration results are employed to measure the absolute hydrodynamic instability growth of sinusoidally perturbed sample, under the condition of the same configure, and the growth factors at different times are given. The results show that the method of measuring the absolute hydroponics instability growth is established successfully.
