Simple model for gas holdup and liquid velocity of annular photocatalytic external-loop airlift reactor under both bubble and developing slug flow

Based on the momentum conservation approach, a theoretical model was developed to predict the superficial liquid velocity, and a correlation equation was established to calculate the gas holdup of an annular external- loop airlift reactor(AELAR)in the bubble flow and developing slug flow pattern. Experiments were performed by using tap-water and silicone oil with the viscosity of 2.0 mm²/s(2cs-SiO)and 5.0 mm²/s(5cs-SiO)as liquid phases. The effects of liquid viscosity and flow pattern on the AELAR performance were investigated. The predictions of the proposed model were in good agreement with the experimental results of the AELAR. In addition, the comparison of the experimental results shows that the proposed model has good accuracy and could be used to predict the gas holdup and liquid velocity of an AELAR operating in bubble and developing flow pattern.     

在经济学中使用数学方法的收益与成本分析

经济学的发展表明,数学方法是经济学中最重要的方法之一,是经济理论取得突破的重要工具.但是目前经济学也存在着数学形式主义的倾向,引起了一些经济学家的批评.本文力图在简要回顾在西方经济学中使用数学方法的历史后,对经济学中使用数学方法带来的收益与成本作具体分析,并对其运用的利弊权衡和应持的态度进行探讨.     

Measures of Teachers' Workload

The measurement of teachers' workload has till now been subjective. Teachers feel that they have a great responsibility to their pupils and to society and their workload heavy, while non-teachers may have different views. This debate occurs even amongst teachers teaching different subjects and levels in a school as well as amongst teachers in different schools. A comparison of teachers' workload in different countries is also particularly difficult because of different class sizes, curriculum time, etc. It is therefore essential to provide a quantitative and objective measure for evaluating teachers' workload. This measure can then be used as a reference by school principals when allocating extra duties to teachers. It is also useful to education authorities when deploying teachers to various schools in centralized education systems.     

学习实践“三个代表”重要思想加强高校领导班子和各级干部队伍建设

江泽民同志“三个代表”的重要思想,是加强党的建设的行动纲领,也是新形势下加强高校领导班子和各级干部队伍建设的必然要求,长期以来,高校领导班子和各级干部在推进高校的改革发展建设方面做出了较大贡献,但面对新世纪、新形势、新情况,新任务,他们还存在一些与改革,发展,建设不相适应的问题,必须认真学习实践“三个代表”重要思想,全面加强领导班子和各级干部队伍的思想,政治,组织和作风建设,只有这样,才能更好地肩负起时代的重托。     

浅谈高校科研文化建设

科研文化是高校组织文化的一部分,科研文化建设与高校科研管理工作密切相关。高校科研文化建设要以科研管理为切入点,提升高校科研文化的思想性,并加强科研文化体制的建设。     

一国两制是和谐选择的结果

“一国两制”理论的提出和实施是中国社会发展的和谐选择。它把历史和现实、多数人的利益和少数人的利益、单一制的国家结构和复合制的国家结构、社会主义制度和资本主义制度和谐地统一在一起,实现了地方高度自治下的祖国安全统一。双方取长补短,相互借鉴,有利于中国政治、经济、化的发展。     

两性关系中的权力归属

现行的社会秩序体现了男性的意志、男性社会的意识形态特征。这种特征由性别地位、性别角色和性别气质构成。它们分别属于政治范畴 ,社会范畴 ,心理范畴 ,三者之间相互依赖 ,形成三体相连而又相互独立的独联体。男性认为女性是他者 ,他者的存在是威胁和危险。于是男性必须排除这种威胁和危险     

新词新语研究中的几个问题

文章对新词新语的界定问题,旧词产生新义算不算新词语的问题,字母构成、数字构成算不算词的问题,新词新语应用中的特殊语法现象问题,多音节词和缩略词的同步滋生以及缩略词与原词语结构的不等同性问题以及新词新语的规范等相关问题进行了思考和探讨.     

历史消费主义影视剧的文化模式

中国当下，伴随着消费对象的不断“越界”，历史消费主义影视思潮呈现出日渐明显的泛化态势。从历史消费主义影视剧的内部配方机理入手，可以把历史消费主义影视剧归纳为“配方”、“怀旧”、“噱头”、“小历史”、“游戏”、“反历史”等文化模式。历史在历史消费主义的尽情游戏中“迷失”了。无论历史消费主义影视剧走着怎样的路线，始终不变的是“消解-确立”模式。
