The above method can be used as a general method of determining molecular weight distribution of polymers.4.Solid-state ~1H wide-line NMR and ~(31)p magic angle spinningNMR were applied to a series of PEI/DNA complex samples with different PEI molecular weights and nitrogen/phosphatemolar ratios,in order to disclose the influence of various structural factors on the interactions and morphology.The results of ~1H NMR spectra showed that the linewidth of the PEI signal was greatly broadened with increasing the N/P ratio.Meanwhile,in the ~(31)p M_AS experiment,the signal was found to shift upfield with the increase of the N/P ratio.Both ~1H and ~(31)P NMR experiments demonstrated that the interaction between two constituents and subsequently the morphology of the complexes vary with the N/P ratio.

首次将固体核磁共振应用到聚合物/DNA复合物体系，观察复合物体系中不同N/P比对其相互作用和相结构的影响，研究表明N/P比的变化对聚乙烯亚胺/DNA基因递送体系分子水平上相互作用有着很大的影响；另外，还发现不同分子量的聚乙烯亚胺聚合物载体在N/P比为3的情况下对复合物中DNA的微观尺度没有明显影响；通过氢的自旋扩散实验，首次测得在PEI/DNA复合物体系中DNA相尺寸的大小，并发现在体系中N/P比达到3以上的复合物中DNA和PEI达到了分子水平上的相容。

The enhanced emission yields of secondary ions induced by Si2 clusters at the low energies are clearly seen and attributed to the vicinage effect of the nuclear collision processes of cluster constituents and the secondary ion emissions are still dominated by electronic stopping processes at high energies.

实验结果显示，在以上的生物样品中，MeV能量离子的能量损失值和TRIM程序模拟的结果相吻合，但是透射离子的能量离散值却与TRIM程序模拟结果有很大的不同。结合生物样品的结构不均匀的特性，对Bohr能量离散理论进行了修正，并发现修正后的Bohr能量离散理论计算结果与实验值符合得很好。
