本文根据经验的多原子分子间相互作用势研究了氨基酸的遗传密码子与反密码子的相互识别。我们以RNA12的几何构型为理论模型,计算了RNA12上互补碱基间,非互补碱基间和碱基三联体间的相互作用能,并对碱基异构体参与的非互补碱基配对的相互作用能函数进行了自选尺度拟牛顿法的最优化处理.研究结果可归纳如下:1.从分子间相互作用能的角度阐明了氨基酸遗传密码子与反密码子配对的wobble学说。并指出,当存在一定自由度时密码子的第三个碱基U能与反密码子中碱基G、I的醇式异构体配对,而密码子的第三个碱基A能以顺式构象与反密码子中碱基I配对,并求得它们的最优配位模式。2.现有的大多数密码子和反密码子间的识别关系可由它们之间的相互作用能来说明,从而进一步阐明了密码子与反密码子中碱基间直接的物理的相互作用在密码子与反密码子的高度专一性识别过程中起着重要的作用。

PU/EP IPNs were synthesized by bulk polymerization technique.The characterization of the IPNs was done by using transmission electroscopy (TEM),FT-IR and Rheo-vibron.TEM results revealed that the PU/EP IPN has a mophological structure consiting of EP particles in PU matrix and the EP domain size varies within 500A to 80oA.The mophological feature of the IPNs depends on the weight ratio of PU and EP,the cross-linking dentsity of PU,the viscosity of the uncured epoxy resin,the length of the soft polyether segment...

PU/EP IPNs were synthesized by bulk polymerization technique.The characterization of the IPNs was done by using transmission electroscopy (TEM),FT-IR and Rheo-vibron.TEM results revealed that the PU/EP IPN has a mophological structure consiting of EP particles in PU matrix and the EP domain size varies within 500A to 80oA.The mophological feature of the IPNs depends on the weight ratio of PU and EP,the cross-linking dentsity of PU,the viscosity of the uncured epoxy resin,the length of the soft polyether segment in the PU network.FT-IR spectra showed that the PU and EP networks in the IPNs are chemically independent with each other and only the physical permenent entanglement of their chains exists.The dynamic mechanical spectroscopy (DMS)of the PU/EP IPNs was studied by usingRheovibron DDV-Ⅲ-EA (TOYO Baldwin,Japan).The results showed the two Tg peaksshifted inward,and the tan has high values (>0.4) over a wide temperclure range(>100℃) These phenomenon result from the permenent entanglement (interpenetration)of the PU and EP chains in the IPNs.Conclusions may be drawn from the DMS studies that the degree of the inwerd shifting of two Tg peaks correlates well with the TEM studies discussed in our previous paper and the STNs synthesized have exellent damping property which is proved further by using a method of sheet measurement.

用一步本体法合成了聚醚氨酯/环氧树脂(PU/EP)互穿聚合物网络(IPN)。以透射电镜(TEM)、红外光谱(FT-IR)及动态粘弹仪(TOYO Baldwin Rheovibron DDV-Ⅲ-EA)对IPN体系前进行了表征,并以自行设计的悬臀梁法测量了该体系的阻尼性能。结果表明:PU/EPIPN中PU和EP两高分子网络间存在着强物理相互作用——互穿作用而无化学相互作用。互穿作用的大小依赖于PU/EP原料配比、PU交联密度、PU软段长度、PU扩链剂结构及未固化EP的本体粘度等因素;该IPN体系的阻尼温域宽(大于100℃)且阻尼值高(tgδ大于0.4),是性能优越的阻尼材料。由表征结果对该IPN体系的形成过程进行了探讨,提出了互穿——迁移相竞争的概念。

A computer interface technique was applied to the data collecting system of theapparatus for measuring freezing points of mixtures. The sampling of experimentaldata, the plotting of heating curves and calculating of freezing points and activitycoefficients were completed automatically. The apparatus is capable of measuring thefreezing point of mixtures with a reproducibility of ±0.001K and the solvent partialmolar excess Gibbs free energy with a reproducibility of ±0. 1J mol~(-1). In this paper, the solvent activity coefficients of binary associated mixtures havebeen measured for n-propylamine, isopropylamine, n-butylamine, isobutylamine, n-amylamine, isoamylamine, diethylamine, diisopropylamine, triethylamine and tributy-lamine in benzene and p-xylene. The mole fraction concentrations of solute areranged from 0 to 0. 1 and 0 to 0.2 for benzene and p-xylene respectively. The sol-vent activity coefficients for all systems are greater than unity. A modified three-parameter association model, which contained a dimerization constant K_2, a formationconstant K for higher polymers and a non-specific interaction parameter w, was usedto treat the experimental activity coefficients. Under the condition of w=0, thisthree-parameter model is reduced to the ideal association model. It is shown thatthe association constants K_2 decrease in the following order: Primary amines>secondary amines>>tertiary amines A similar order exists for the constant K. These results are in accordance withthe fact that self-association does not occur in tertiary amines. No regular order for the empirical non-specific interaction parameter w has beenfound. But there is also no apparent difference among the values of w of the stu-died systems. It can be safely assumed that the interaction parameter w reflects thephysical interaction of the components in the studied mixtures.

本工作利用计算机技术改进加热式凝固点测量装置的数据采集系统.改进后装置的混合物凝固点测量再现性为±0.001K;溶剂偏摩尔过量自由能测量再现性为±0.1J.mol~(-1).用凝固点降低法测量正丙胺、异丙胺、正丁胺,异丁胺、正戊胺、异戊胺、二乙胺、二异丙胺、三乙胺、三正丁胺分别与苯和对二甲苯构成二元混合物的溶剂活度系数.并使用一个包含物理相互作用的三参数连续缔合模型拟合实验数据.结果表明该模型能较好地刻画所研究的二元缔合混合物。
