By carrying out ~1H spin-diffusion experiments,the domain sizes of DNA in the complexes were determined.The domain size of DNA is found to decrease greatly when the N/P ratio changes from 0.5 to 3 and changes only slightly with further increase of the N/P ratio.After making a thorough analysis and discussion on drug control release and gene delivery systems with general NMR techniques,we presents a method of 1D PFG NMR technique to realize quick observation on the Mw change of polymer during its degradation process.Moreover,according to the inverse Laplace transformation theory and based on a function of diffusivity distribution of polymer in solution,2D PFG NMR technique is developed to measure the Mw distribution of polymer.Combined with Monte Carlo simulation,the degradation mechanism can be figured out.

针对施工期现浇钢筋混凝土结构的时变性，定义楼板刚度与模板支撑的刚度比为施工时变结构体系的弹性特征值，建立了以施工时变结构体系弹性特征值为参数的现浇钢筋混凝土结构施工受力性能分析的弹性支撑连续梁模型，基于该模型，分析了施工期现浇钢筋混凝土结构的受力特性，发现在特定施工方案下，当施工时变结构体系的弹性特征值较小时，最大施工荷载出现的楼层位置会提前，而拆模时间也会改变最大施工荷载出现楼层的位置；施工时变结构体系的弹性特征值和拆模时间都影响楼层承担的最大施工荷载比率(荷载比率定义为结构承担荷载与楼板自重的比值)；施工期楼层承担的最大施工荷载随楼层位置呈现波动特性，随楼层位置增高波幅逐渐减小，最后趋于稳定。

Technology also undergoes the process of socialization, which is defined as "soci-technological" process. One of its influences is that technology changes the meaning of security and war, and the understanding of the other countries and this is an important factor of the transformation of international system.

科技对国际体系的影响表现在宏观和微观的层面，从宏观上讲，一国整体科技实力的提高是其国家整体实力得以提高的保证，国家的力量发展不平衡从而导致了国际体系的变动，从微观上，拥有某些尖端武器和前沿技术的国家极大地影响着国际体系的变动，这两种情况有一个共性是都能使国际体系的变动朝着自己有利的方向发展。

The dispersion of particles are also related to the interactionbetween nanosilver and polymer. Nanosilver dispersed well in PS, while form larger branchedclusters in PMMA, and polymers could prevent nanoparticles from aggregation. The interaction between nanosilver and polymers depends on the properties of polymers and treatment. XPS results indicated that no obvious interaction between nanosilver and PS was foundbefore and after heat treatment; for AS matrix, there exists a interaction between nanosilver and AN,moreover AN on the nanosilver surface could cyclize and lose N after heat treatment at 150℃ for1h; for PMMA matrix, there exists a interaction between nanosilver and O atoms, heat treatment at150℃ for 1h could lead to the reaction between Ag, S and O in the interlayer of composite andchange the interface interaction.

纳米银粒子的加入改变了聚合物体系对激光能量的吸收和转换方式，导致其激光离解方式的变化，通常此种粒子会促进聚合物的炭化，且在界面可能有诱导石墨化的作用；而银粒子自身的离解及其对基体激光离解的作用都受两相的界面相互作用的影响，即与聚合物基体的性质、后处理等有关，热处理后两相界面的变化对PS和AS体系的炭化影响不大，但PS体系中银团簇的最大原子聚集数减小；而对PMMA体系则基本上消除了激光炭化。

The results indicated that both binary interactive parameters of water/isobutanol system from this work and the parameters of water/ethanol from literature can be used to precdict the liquid-liquid equilibria of water/ethanol/isobutanol. But the parameters of ethanol/isobutanol from the literature were not appropriate for the prediction. Furthermore, the model parameters from 30℃ can can be used to predict the liquid-liquid equilibria under 35 ℃. The model parameters of water/isobutanol are independent on the temperatures, so constant parameters irrelative to temperature can meet prediction accuracy. Othmer-Tobias/Bancroft equation was also used to fit the liquid-liquid data of water/ethanol/isobutanol system, but it didnt possess the performance of predicting the liquid-liquid equilibria.The partition coefficients of dipotassium glycyrrhizinat were determined in the liquid-liquid two-phase system of water/ethanol/isobutanol and corrected by experiential equation.

结果表明：由本文的二元液液相平衡实验数据关联得到的水+异丁醇体系的相互作用参数和文献上由二元气液相平衡数据关联得到的水+乙醇体系的相互作用参数都具有预测三元液液相平衡关系的能力，而文献上由二元气液相平衡数据关联得到的乙醇+异丁醇体系的相互作用参数不具有预测三元液液相平衡关系的能力；可以用从30℃三元液液相平衡数据关联回归得到的模型参数来预测35℃时的液液相平衡关系；水+异丁醇的相互作用参数与温度关系不是很密切，计算时取与温度无关的常数即能满足关联精度要求；Othmer-Tobias和Bancroft经验方程可用于水+乙醇+异丁醇两相体系的液液相平衡关系的关联计算，但这类经验方法并不具有预测能力。
