A Study on Health Supervision for Centralized Tableware Disinfection Industry in Xiamen

随着近年来中国老百姓生活水平的迅速提高和社会经济交往活动的增加,特别是近几年来,人们日益加快的生活节奏以及潮汐性的工作规律,在外就餐已经成为我国普通百姓的日常生活另一选择。餐饮具消毒问题一直都是餐饮消费者关注的热点，很多中、小型餐饮店没有消毒能力或消毒制度不落实，给急性肠道传染病传播提供了机会。集中式消毒餐饮具的出现和普及，弥补了这一缺陷，提高了餐饮具消毒质量，为确保餐饮消费环节食品安全等发挥了积极作用。但近年来，餐饮具集中消毒行业出现了诸多管理乱象，限制了产业的发展，直接危害消费者健康权益。 本文以探讨厦门市餐饮具集中消毒行业的卫生监管现状及对策为研究目的，采用文献研究、现场调查、问卷调查...With the rapid improvement of Chinese ordinary people’s living standard, increase of social economic communication activities, especially plus the acceleration of residents’ living tempo and upgrading of consumption concept in recent years, dining out has already become a part of ordinary people’s daily life.

AN ADAPTIVE ITERATION METHOD FOR STRUCTURAL STATIC REANALYSIS of TOPOLOGICAL MODIFICATIONS

基于guyAn缩减和EPSIlOn算法,提出了结构拓扑修改静态重分析的自适应迭代方法。首先将新增加的自由度通过guyAn缩减方法凝聚到原结构自由度上,形成缩减方程。其次,根据刚度矩阵增量,利用nEuMAnn级数建立基向量,采用向量EPSIlOn算法对基向量部分和系列进行迭代加速,并给出了控制迭代收敛精度的误差计算方法,可以根据结构改变的大小自适应选择迭代次数,从而快速求出原结构自由度的位移。新增加自由度的位移可从缩减方程恢复得到。给出了一个数值算例,将该方法与组合近似法(CA)进行比较。数值计算结果表明,该方法可以根据精度要求自动选择迭代次数,且计算效率比CA方法高。Based on the Guyan reduction and epsilon algorithm, an adaptive iteration method for structural static reanalysis of topological modification is presented.In this process, the equations of the newly added degree of freedoms(DofS)(if any) are condensed to the original structure by means of Guyan reduction.And then, the basis vector is formed using Neumann serial according to the increment of the stiffness matrix, and the epsilon algorithm is used to accelerate the convergence of the partial sum of the basis vectors.An error evaluation method is introduced to control the accuracy of the iteration adaptively.A numerical example is given to compare the computational cost and approximation accuracy between the combined approximation and the presented method, the numerical results show that the present method is effective and easy to integrate into a general optimization approach.国家自然科学基金项目(50905033);中国博士后科学基金项目(20070420761);广东省自然科学基金项目(8451009001001414);广州市科技计划项目(2006Z2-D9061);广东省科技计划项目(2009B010900032);粤港招标项目(20070103-1

压缩拐角激波与旁路转捩边界层干扰数值研究

为了研究激波与旁路转捩边界层的干扰机理,采用直接数值模拟(DNS)方法对来流马赫数Ma∞=2.9,24°压缩拐角内激波与转捩边界层的相互作用进行了系统的研究。考察了旁路转捩干扰下压缩拐角内分离区形态和激波波系结构的典型特征。比较了转捩干扰与湍流干扰流动结构的差异,并分析了造成差异的原因。研究了拐角内转捩边界层的演化特性,探讨了转捩干扰下脉动峰值压力和峰值摩阻的分布规律及形成机制。研究结果表明:相较于湍流干扰,两侧发卡涡串的展向挤压使得分离区起始点以V字型分布,且分离激波沿展向以破碎状态为主,激波脚呈现多层结构;拐角内的干扰作用急剧加速了边界层的转捩过程;转捩干扰下的拐角内峰值脉动压力以单峰结构出现在分离区的下游,同时干扰区内的强湍动能和高雷诺剪切应力使得其局部峰值摩阻系数要高于湍流干扰
