Preconditioning high-dose vitamin C for the dialyzer can decrease AOPP in HD patients.

大剂量维生素C预冲透析器对血液透析患者AOPP升高有抑制作用。

It is found that there exists an obvious prepeak in the low-Q domain (Q=15.7 nm^-^1) of the structure factor. In the X-diffraction pattern, the liquid diffraction curve is corresponding with the solid diffraction curve. There exist the prepeaks for them in the low-Q domain, which shows that there is the comparability in the microstructure between them.

采用紧束缚原子间作用势，利用分子动力学模拟的方法研究了Al5Fe2合金熔体的微观结构，发现在结构因子的小角部分(Q=15.7nm^-^1)出现了一个明显的预峰，并得到X射线衍射实验的进一步印证，在实验测得的合金衍射图样中，液态衍射曲线与固态衍射曲线间存在着很好的对应关系，它们在小角部分都存在峰位，这表明Al5Fe2合金熔体与其固态在结构上存在着很大的相似性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
