栀子蓝色素的制备及其抗氧化活性研究

用米曲霉发酵产物水解栀子苷,水解产物与味精反应制备栀子蓝色素,采用DM-2大孔树脂对产品进行精制,通过DPPH·捕获分光光度法测定栀子蓝色素精制前后的抗氧化活性.栀子蓝制备的最佳条件为:10.64 g栀子苷和129.36 g水混合后,加入米曲霉发酵液9.8 m L,在50℃,160¹80 r/min下水解6 h后,与3.15 g味精反应40 h,80℃保温30 min.所获栀子蓝色素粗品的色价(E1%1cm)为90.56,经DM-2大孔树脂纯化后产品色价提高至180.01%,收率为90.96%.抗氧化实验表明栀子蓝色素粗品和精制品均能有效清除DPPH·,且精制后的栀子蓝色素产品清除DPPH·的能力增强.     

Statistical inference for simple tree order in the means of stochastic order on stratified contingency tables

In this paper, we consider testing the hypothesis that all multinomial populations in the stratified contingency table are identically distributed against the alternative that all these popula-tions are in simple tree order. We provide an asymptotic represen-tation of the order-restricted maximum likelihood estimate of the unknown parameters. The resulting estimators are proven to be n-consistent and asymptotically normal under appropriate con-ditions. A chi-squared test method is used for this hypothesis t...     

由原型理论看英语词义变化机制

在语言这个科学系统中，词汇是最活跃、最具可变性的一部分。长期以来，词汇结构并不是词汇变化的主要方面，因而研究词义变化就显得尤其重要。运用原型理论来探究词汇领域稳定性与灵活性并存的现象，能够更好地分析出词义变化机制。这对英语的词汇学习有一定启示。

Satellite Image Adaptive Restoration Using Periodic Plus Smooth Image Decomposition and Complex Wavelet Packet Transforms

A satellite image adaptive restoration method was developed that avoids ringing artifacts at the image boundary and retains oriented features. The method combines periodic plus smooth image decomposition with complex wavelet packet transforms. The framework first decomposes a degraded satellite image into the sum of a "periodic component" and a "smooth component". The Bayesian method is then used to estimate the modulation transfer function degradation parameters and the noise. The periodic component is deconvoluted using complex wavelet packet transforms with the deconvolution result of the periodic component then combined with the smooth component to get the final recovered result. Tests show that this strategy effectively avoids ringing artifacts while preserving local image details (especially directional textures) without amplifying the noise. Quantitative comparisons illustrate that the results are comparable with previous methods. Another benefit is that this approach can process large satellite images with parallel processing, which is important for practical use.     

废内燃机油的预处理过程及其产物性质分析

对废内燃机油进行了热处理-蒸馏深拔的预处理研究,结果表明:经过热处理后两种废油40℃的黏度分别降低36.20%和48.79%,杂原子总含量分别降低56.11%和50.25%,杂元素总含量分别降低86.81%和87.12%,基本达到降黏除杂的目的;热处理后的废油经蒸馏深拔后回收利用率达到了89.72%,同时实现了黏度的进一步降低,杂原子和杂元素的进一步脱除,获得了适合加氢改质的原料油。     

Stabilization of Euler-Bernoulli beam with a nonlinear locally distributed feedback control

This paper studies the stabilization problem of uniform Euler-Bernoulli beam with a nonlinear locally distributed feedback control. By virtue of nonlinear semigroup theory, energy-perturbed approach and polynomial multiplier skill, the authors show that, corresponding to the different values of the parameters involved in the nonlinear locally distributed feedback control, the energy of the beam under the proposed feedback decays exponentially or in negative power of time t as t → ∞.     

论事件的时间与时间中的事件——梅勒时间观探析

梅勒的时间观是基于两种分类方式而产生的:A时代和B时代,前者是相对的、以现在为参照,后者是绝对的、不以任何事物为参照。A时代、B时代对于时间的不同版本就是对于事件的不同看待。事件是时间中的实体,与事物相比具有时间性,与事实相比更具客观性。通过对梅勒时间观点的研究,可以发现时间和事件的关系,二者是统一的,不是单纯的变化关系,而是一种以因果联系为主的属性关系。
