摘要: 在Z-pinch实验物理诊断中使用底片记录1维时空分辨X光功率图像，利用模拟底片能量响应曲线对实验获得的X光功率图像进行了变换，以闪烁体X光功率谱仪获得的X光波形为参考，将变换后的图像沿空间轴积分，并将所得波形与参考波形相比较，两条曲线基本一致，表明所使用的模拟能量响应曲线具有较好的近似效果。Abstract: In Z-pinch experiment, the one-dimensional temporal-spatial distribution of X-ray power is recorded by photographic films with nonlinear luminosity response. After processing by using a simulative characteristic function, the X-ray images are spatially integrated and then compared with X-ray waveforms obtained with X-ray Power Meter. The results show that the two kinds of waveforms are well coincident, which validates the capacity of the simulative characteristic function.
