食用花卉中微量元素Fe、Zn的蛋白质结合态分布

本文以食用花卉中的菊花，芙蓉花，金银花为实验材料，采用原子吸收分光光度法测定了此3种花卉中微量元素Fe,Zn的水溶性蛋白质结合态含量及形态分布。结果表明，Zn元素蛋白质结合态分布较多，平均为20．26％，Fe元素蛋白质结合态分布平均为13．06％，金银花和菊花中的Fe,Zn蛋白质结合态形态分布更为接近，而且均比芙蓉花高。

用通用计算流体力学程序FLUENT计算了中国氦冷固体增殖实验包层模块(TBM)冷却剂丧失事故中的冷却剂排放瞬态过程。并为中国氦冷固体增殖实验包层模块冷却剂丧失事故(LOCA)分析开发了一维喷放和余热排除计算模型。典型LOCA事故的分析结果显示,TBM诱发事故或ITER其它部件诱发TBM事故对整个ITER系统安全造成的总风险不严重。     

Waveguides Induced by Screening-Photovoltaic Solitons in Biased Photorefractive-Photovoltaic Crystals

We investigate theoretically waveguides induced by screening-photovoltaic solitons in biased photorefractive-photovoltaic crystals. We show that the number of guided modes in a waveguide induced by a bright screening photovoltaic soliton increases monotonically with the increasing intensity ratio of the soliton, which is the ratio between the peak intensity of the soliton and the dark irradiance. On the other hand, waveguides induced by dark screening-photovoltaic solitons are always single mode for all intensity ratios and the confined energy near the centre of a dark screening-photovoltaic soliton increases monotonically with the increasing intensity ratio. When the bulk photovoltaic effect is neglectable, these waveguides are those induced by screening solitons. When the external field is absent, these waveguides predict those induced by photovoltaic solitons.     

大量钴镍铬存在下直接测定铁

经典的汞盐法测定铁,不仅污染环境且不适于大量钴镍铬存在下铁的直接测定。因为这些离子本身有颜色,用二氯化锡还原铁(Ⅲ)时,较难观察铁(Ⅲ)黄色消失,可靠性不大。本文提出用铝片还原并以中

面向对象的软件原型化可操作模型OPM

基于OMT(Object Modeling Technique),面向软件原型化领域,提出了可操作模型OPM(Object-Oriented Prototyping Modeling)。OPM是在对象模型OM(Object-Model)之上的一种二维的模型化方法,纵向,功能对象的APO抽象与继承的自顶向下模型化机制;横向,功能对象的有穷状态机中,状态对象的AKO抽象与继承的逐步细化的模型化机制。OPM通过当前状态对象的转换、消息授受来描述系统行为,原型化深度通过上述二维的对象模型化粒度来刻划,并给出了OPM应用的具体例子。     

CONSTRUCTION OF COMPACTLY SUPPORTED BIVARIATE ORTHOGONAL WAVELETS BY UNIVARIATE ORTHOGONAL WAVELETS

After some permutation of conjugate quadrature filter, new conjugate quadrature filters can be derived. In terms of this permutation, an approach is developed for constructing compactly supported bivariate orthogonal wavelets from univariate orthogonal wavelets. Non-separable orthogonal wavelets can be achieved. To demonstrate this method, an example is given.     

F同位素的反应总截面测量和17F可能的质子皮结构

应用透射法对中能区F同位素与C靶的反应总截面进行了测量。发现^17F的反应总截面比其邻近同位素的反应总截面稍有增强。用Glauber模型和BUU模型对F同位素进行了差异因子d的分析。^17F的差异因子d比共附近同位素稍有增强。分析结果表明^17F可能存在质子皮结构。
