论文摘要
1993年，Nallet，Laversanne和Roux提出了一个简化的模型，以散布层状相的强度，尽管如此，它仍然非常成功地用于拟合实验结果，尤其是使用粉末系统获得的结果。我认为，模型的成功以及模型的简单表达是由于样本方向的近似集成而导致的，这是由于对散射矢量成分的隐式积分而产生的，导致了导演的正常。
In 1993, Nallet, Laversanne and Roux put forward a simplified model for the intensity scattered by lamellar phases, which was nonetheless very successfully used in fitting experimental results, especially those obtained with powder systems. I argue that the success as well as the simple expression of the model result from an approximate integration over sample orientation, resulting from an implicit integration over the scattering vector component normal to the director.
