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。

Methods Twenty-two adolescent SD female rats were selected. All rats were killed by dislocation of cervical vertebra, the eyeballs were in paraffin imbedding and made to a series of sections, using immunohistochemical method; ERα and ERβ distribution were investigated in uvea tissue of rats; and quantitied by Tanaka scores analytical method. The uteri of rats was used as positive control and PBS as negative control.

选择青春期SD雌性大鼠22只，采用颈椎脱臼处死大鼠，取眼球作常规石蜡包埋，连续切片， SP免疫组织化学方法显示ERα、ERβ在葡萄膜组织的表达；采用Tanaka记分法对ERα、ERβ进行定量分析，并设正常大鼠子宫作阳性对照；PBS代替一抗作阴性对照。

In 1925, R. Nevanlinna established two fundamental theorems of meromorphic functions and the study of the value distribution theory of modern times started.

Firstly, a scalar and vector potential analysis models of tooth-layer magnetic field in a two-degree-of-freedom motor is developed, which is the same as standard hybrid step motor. By applying the finite element method, the distribution of the tooth-layer magnetic field is studied in detail. It provides an effective means for further calculation of performance and parameters of the motor.
