摘要
X射线的相干散射图样呈高斯分布,本文通过高斯分布的理论模拟理想状态下的散射分布图样,在此基础上进一步模拟噪声影响和偏心影响,从而推断出试验图像中分布特征的本质,为后期的分析工作提供依据。
The pattern of X-ray coherent scatter contributes a Gauss distribution.In this paper,the coherent scattering patter was theoretically simulated by Gauss distribution modal.On the basis of it,the affection of noise and eccentric were simulated,so the essential character of the distribution of experimental images has been deduced.These results provide the theoretical support for the later analysis.
