流态化速冻装置布风板实验研究

针对目前流态化速冻装置在速冻过程中速度分布和压力分布不均匀导致食品流化状态与冻结效果不佳等缺点,课题组从布风板孔隙形状（正方形、三角形和圆形）、孔隙率和孔隙分布3个角度出发,设计出16种布风板,以提高装置对不同种类食品的适应性要求,提高装置能效比从而达到节能的目的。文中研究设计的布风板可改善流态化速冻装置在冻结过程中的流化程度与冻结效果,同时不同孔隙形状的设计也满足食品颗粒形状的多样性需求。

An individual-based model of information diffusion combining friends’ influence

In many real-world scenarios, an individual accepts a new piece of information based on her intrinsic interest as well as friends’ influence. However, in most of the previous works, the factor of individual’s interest does not receive great attention from researchers. Here, we propose a new model which attaches importance to individual’s interest including friends’ influence. We formulate the problem of maximizing the acceptance of information (MAI) as: launch a seed set of acceptors to trigger a cascade such that the number of final acceptors under a time constraint T in a social network is maximized. We then prove that MAI is NP-hard, and for time \(T = 1,2\) , the objective function for information acceptance is sub-modular when the function for friends’ influence is sub-linear in the number of friends who have accepted the information (referred to as active friends). Therefore, an approximation ratio \((1-\frac{1}{e})\) for MAI problem is guaranteed by the greedy algorithm. Moreover, we also prove that when the function for friends’ influence is not sub-linear in the number of active friends, the objective function is not sub-modular.

试论邓小平外交思想的历史渊源

邓小平外交思想是中国进入改革开放新时期正确处理我国与世界各国外交关系的指导思想。邓小平外交思想的历史渊源表现在把国家的主权、安全和国家利益放在第一位 ,秉承中华民族优秀的文化传统 ,对时代特征作出准确判断 ,是对毛泽东独立自主外交思想的有效继承和发展。     

有效政府的理论基础及其建构

生态环境的动态性和复杂性决定了政府行政必须以灵活性和有效性作为根本价值取向。有效政府不仅是一种价值 ,更是一种运作过程和运作结果。它不是有限政府 ,更不是无限政府。树立有效政府理念 ,是对政府管理的创新和突破 ,它必将有助于政府实践的发展 ,实现政府行政的现代化。     

我国民事诉讼辩论原则的缺陷及其完善

辩论主义原则是民事诉讼的基本原则之一 ,也是我国辩论原则的法律依据。我国的辩论原则与真正的辩论主义原则尚有很大的距离 :程序的独立价值被否定 ,程序公正不能实现。这需要从加快立法进程和加大执法力度等方面加以完善。     

走向多元化的俄罗斯技术哲学

当代俄罗斯技术哲学和西方技术哲学相比,总体上还存在着较大差距,但俄罗斯技术哲学在保持自己传统优势的前提下,正在引进西方技术哲学特别是工程伦理学和技术社会学的合理成分,努力形成自己的特色。对20世纪90年代以来俄罗斯技术哲学发展现状、主要成果和发展方向进行了介绍和预测,指出多元化将是俄罗斯技术哲学的发展趋势,而技术本体论、技术价值论和工程伦理学将是它的研究重点。

Psychological mechanisms of investors in Chinese Stock Markets

The study investigated the psychological mechanisms of risky investment behaviors in Chinese Stock Markets. A 42-item questionnaire was developed and distributed to 1547 individual investors recruited by stratified random sampling from Nan Fang Bond Company. A speculative orientation and a low level of risk perception among Chinese investors were revealed. The results also showed that investors were deficient in investment knowledge and skills. Structural equation modeling was used to generate a risk perception-mediated model for investment behaviors. We found that information from organizational/institutional level can precipitate low risk perception and policy-oriented speculation of investors, which could be accounted for by the collectivistic culture in China and may not be beneficial to risk management in Chinese Stock Markets. Suggestions were made regarding the further development of stock markets in China.
