A Study of Information Support in Governmental Public Decision-making

信息化浪潮方兴未艾，时代的发展对公共决策科学化提出了新的要求和挑战，这使得信息系统日益凸显其在政府公共决策中作为神经系统的地位和作用，公共决策的科学正确在很大程度上取决于信息支持的程度如何。本文在厘清信息、信息资源管理等概念以及信息支持与公共决策关系的基础上，指出当前政府决策的信息弱化现状及问题，进而从动态和静态两个层面，文图结合，重点探讨了政府公共决策信息支持的核心——政府综合信息资源库群建设和信息资源管理及系统流程建构，并运用具体案例即厦门市决策咨询委员会信息服务平台建设进行深入阐释。全文共分为五个部分：第一部分：公共决策与信息支持概述。从数据、信息、信息管理、信息资源管理的概念入手，提出...The present thesis is an detailed discussion on the core of information support in public decision-making----the construction of comprehensive information resource database in government, information resource management and the construction of systematic flow.

Mixing Effect of Two-Dimensional Micromixers Based on the Deformed Square-Wave

设计并制作了多种二维变形方波微混合器,通过荧光观测及标准偏差数值分析,在低rE数(rE≤13.33)时,考察拐角和单元长度对混合器混合效果的影响。结果表明,集成拐角的混合器存在一个临界rE值1.3,当rE1.3时,可以产生回流,混合效率随着拐角的减小逐渐提高。对于集成6个单元、拐角为45°、单元长度(S)为3132μM的微混合器,在雷诺系数rE=13.33时,混合效率为56%,约提高了1倍;但当拐角与混合单元长度增大时,混合效率明显降低。A series of two-dimensional micromixers based on the deformed square-wave were designed and fabricated.The effect of the turning angle and unit length on the mixing efficiency at low Reynolds number(Re≤13.33)was investigated by fluorescence observation and numerical analysis of the standard deviation from the pixel intensity distribution.The results indicate that the mixer with the integrated turning angle has a critical Reynolds value of 1.3.The mixture only depends on the molecular diffusion and the mixing efficiencies remained at about 28% when Re1.3.For the micromixer of six square-wave units with 45° turning angle and 3 132 μm unit length,the mixing efficiency is increased to 56% at Re=13.33.However,the mixing efficiency is decreased with turning angle and unit length increasing.国家基础科学人才培养基金资助项目(J0630429);福建省自然科学基金计划项目(D0740013);集美大学科研基金资助项目(ZQ2007001

Y-shaped electric -field free electro -osmotic pump with small sub -channels in parallel

设计并制作了一种y型无电场电渗泵芯片,以聚电解质静电自组装技术在侧臂通道分别修饰正、负电荷形成电渗泵,实现中间主通道无电场干扰。侧臂由多个平行亚通道构成,以增强电渗泵流速。使用中性离子示踪法、毛细管法分别测定电渗泵流速与压强,考察了电场、亚通道个数及深度对流速与压强的影响。结果表明,流速、压强随外加电场增大而增大,并呈线性关系;流速随侧臂亚通道个数增大而增大,压强随通道深度减小而增大。当电场强度为600V/CM时,含9个深10μM、宽度25μM亚通道的电渗泵流速与压强分别为672nl/MIn和442PA。A novel Y-shaped electro-osmotic pump consisting of two arms which has small sub-channels in parallel was developed.Two arm-channels were modified with cationic and anio-nic polyelectrolyte respectively,allowing a field-free flow to be generated in main-channel.Flow rate and pressure were measured by particle tracking and capillary method respectively,and the influence of electric field, numbers and depth of sub-channel on flow rate and pressure was investigated as well.Results showed that both of flow rate and pumping pressure increased linearly with electric field.As the number of subchannels increases,the flow rate becomes higher by increasing the cross-sectional area at a constant electric field.Meanwhile,the pressure falls as depth of sub-channel increases.Flow rate and pumping pressure were 672nL/min and 442Pa respectively for the pump with 9 sub-channels(10am deep、25μm wide)in parallel,when electric field was 600V/cm.国家自然科学基金面上项目20675066;国家基础科学人才培养基金J0630429项目资

以γ-氨丙基三乙氧基硅烷(KH-550)为先驱体,应用溶胶-凝胶技术在织物表面形成一层凝胶薄膜.由于该薄膜含有氨基和羟基等活性基团,能与钯离子起配位络合作用,阻止钯粒子的团聚,使钯以较高的活性完成织物化学镀.扫描探针显微镜(SPM)及扫描电子显微镜(SEM)观察了施镀前后织物的表面形态.与传统的前处理相比,无需SnCl2敏化,减少污染,缩短工艺流程,降低钯盐用量.Using KH-550 as precursors,gel thin films were formed on fabric by sol-gel method.By complexed with palladium ions due to the presences of amido and hydroxide in the gel thin films,the aggregation of palladium particles was inhibited.Therefore,Palladium could exhibit better catalytic activity in the process of electroless plating.The surface morphology of fabric was observed by SPM and SEM.Campared with the traditional pretreatment process,no SnCl2 was needed.This method reduced pollution,shortened process flow and reduced the amount of noble metals.作者联系地址：东华大学生态纺织科学技术教育部重点实验室;Author's Address: Key Laboratory of Science & Technology of Eco-Textile,Ministry of Education,Donghua University,Shanghai 201620,Chin
