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 JIC is 0.1513 and the AK is 120.5 respectively. The scanning electron microscope and transmission electron micrograph shows that microstructure of the fracture toughness of new tiny deformation steel (GDL-1) was bunchy bainite+ martensite and a little retained austenite mixed structure. The retained austenitic film separates bunchy bainite into extra-fine subunits and improves the micro-ductility of the steel.

扫描电镜和透射电镜分析表明，空冷后新型高强韧GDL-1钢的显微组织为窄束状贝氏体＋马氏体和部分残余奥氏体复合组织，残余奥氏体以薄膜形态分割贝氏体板条而形成超细化亚单元，增加了材料的微观塑性。

The influence of secondary carbides precipitation and transformation on hardening behavior of a 14Cr-1Mo-1.5V cast iron in sub-critical treatment was studied using optical microscope, transmission electron microscopy and X-ray diffraction.

为了揭示高铬耐磨铸铁硬化的微观机制，提高其使用性能，采用光学显微镜、透射电镜和X射线衍射研究15Cr-1Mo-1.5V高铬铸铁中二次碳化物的析出和转变对其亚临界处理硬化行为的影响。

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