论培育和践行社会主义核心价值观的人民主体思想

培育和践行社会主义核心价值观是围绕人民群众展开的认识和实践活动,体现着唯物史观的人民主体思想。人民群众是实践活动和认识活动的主体,培育和践行社会主义核心价值观需要人民群众作为主体广泛参与。同时,人民群众作为现实的历史主体,其社会意识并不是自发反映时代发展的要求,如何形成正确的价值自觉有赖于社会主义核心价值观的培育。尊重人民群众主体地位的关键在于实现人民群众的根本利益,这是社会主义核心价值观的本质体现

传统孝道规范性的来源及其现代启示

孝道的规范性是指孝道作为行为指示系统在社会生活中的效力。传统社会的孝道规范性来源就是探讨这种效力确立的依据。从传统孝道产生和发挥作用的农业文明的历史境遇中考察,其规范性来源于:外在的权威、规范体系自身的合法性、主体的情感与理性认同三个方面。现代社会的孝道规范是对传统孝道的继承和超越,从传统孝道规范性的来源中获得启示将有助于在新的历史场景中激发孝道的活力

The Research and Implementation of Realtime Business Wireless Multi-hops Access Technology Based on Multi-paths Routing

摘要 随着信息技术的不断发展，人们对移动通信的需求越来越强。移动Adhoc网络具有无中心基础设施和允许节点任意移动等特性，尤其适用于缺乏有线网络、需要进行网络快速部署或动态重配置的应用情形，因此对于应急通信及军用网有着特殊意义，例如可以在消防现场，通过布置一个临时的Adhoc网络，通过消防员身上的背负式终端，将现场视频实时的通过无线网络多跳传输到指挥中心，便于及时、准确掌握现场火灾态势，提高快速反应能力，最大限度地减少损失。 本文在介绍AdHoc网络的基础上，对AdHoc网络的多径路由技术进行分析，并按利用多径路由进行传输的方式，将多径路由分为两类：一种是同时在备份路径上传输相同的数据包，...ABSTRACT As information technology development, people's demand for mobile communication is growing. mobile Ad hoc network with no central infrastructure and allow nodes to move is especially suitable for the case of needing for rapid network deployment or dynamic re-configuration but lack of cable networks, Ad hoc network has special significance for the military and emergency communications net...学位：工学硕士院系专业：信息科学与技术学院通信工程系_通信与信息系统学号：2005130239

Dynamic Analysis of a High-rise-Building Structure during an Earthquake Considering Soil-Structure-Interaction

土－结构体系有限元模拟计算分析的复杂性与计算成本，在一定程度上限制了土与结构相互作用分析在高层建筑结构设计中的应用。上部结构数值解与土解析解耦合的土－结构相互作用计算方法，为高层建筑结构提供了有效途径。利用作者提出的耦合算法，对一个钢框架-混凝土核心筒高层结构进行地震作用下的非线性动力分析,讨论了不同强度地震和不同种类地基土对结构地震反应的影响，得出了对实际工程具有指导性意义的结论。The conventional coupling analysis based on a comprehensive finite-element(FE)model is prohibitive in terms of computational complexity and cost.The coupling method between the numerical modeling of the superstructure and the analytical modeling of the soil provides an efficient approach for SSI.This paper applies this method to a steel-reinforced concrete frame-tube high-rise building and verifies its potential through this case study.Using this method,various soil conditions and earthquake intensities are studied to explore the SSI effects,leading to meaningful conclusions to engineering practice.国家重点研发计划项目(2016YFC0701106)、国家自然科学基金项目(51261120376、5157847

EFFECTS OF SOIL TEXTURE AND LIGHT ON GROWTH AND PHYSIOLOGY PARAMETERS IN KANDELIA CANDEL

在香港的 3个红树林样地即黄竹湾 (沙土 )、西径 (沙壤土 )和米埔 (粘壤土 )进行了土壤结构对秋茄 (K an-delia candel(L .) Druce)生长和生理影响的研究 ,并在米埔比较了林内和林外秋茄幼苗的生长和生理参数以观察光照水平的效应。在沙土和沙壤土生长的 1.5年秋茄幼苗比粘壤土具有较粗的基径和较高的总生物量 ,说明秋茄幼苗在沙土和沙壤土中比在粘壤土中生长更好。沙土 1.5年秋茄幼苗的叶片厚度分别为沙壤土和粘壤土的 1.75和 2 .0 5倍 ,表明沙土中的秋茄幼苗具旱生结构以维持体内水分。然而 ,沙土和沙壤土 4.5年秋茄幼树的叶片厚度无显著差异。沙土和沙壤土中 1.5年秋茄幼苗分配于根系的生物量比例约为 5 0 % ,高于粘壤土的值 (约 40 % )。沙土和沙壤土中 1.5年的秋茄比粘壤土具有较低的叶绿素含量、根系活力、硝酸盐还原酶活性、过氧化物酶 (POX)活性、超氧化物歧化酶 (SOD)活性及较高的丙二醛 (MDA )含量。米埔 1.5年秋茄幼苗在红树林外比林内有更好的长势 ,具有更大的叶面积、特殊叶面积、叶片数量及生物量。林内幼苗具有较高叶绿素含量、较低叶绿素 a/b比值、较高硝酸盐还原酶活性和较强的根系活力。林外幼苗的叶片 POX和 SOD活性比林内的值稍高 ,MDA含量比林内显著要高Growth and physiological changes in Kandelia candel (L.) Druce with varying soil texture were investigated at three sites in Hong Kong: at Wong Chuk Wan(sandy soil), Sai Keng(loamy-sandy soil) and Mai Po(silty-loamy soil). The effects of light level were studied at Mai Po by comparison of plants located under a mangrove canopy with those in a light gap. 1.5 year old K. candel plants had a larger basal stem diameter and higher total biomass in sandy and loamy-sandy soil than in silty-loam soil, partially indicating that K. candel seedlings can grow better in sandy soil than loamy soil. Leaf thickness of 1.5 year old K. candel seedlings growing in sandy soil was 1.75 and 2.05 times that of seedlings from loamy-sandy soil and silty-loamy soil, respectively, indicating that K. candel seedlings developed a xerophilous character to maintain water. However, this response is dependent on plant age as no significant difference was observed in leaf thickness of 4.5 year old plants growing in sandy and loamy-sandy soil. In 1.5 year old K. candel seedlings more biomass was allocated to roots in sandy and loamy-sandy soils (about 50%) than silty-loamy soil (about 40%). 1.5 year old K. candel plants had a lower chlorophyll content and lower root, reductase, peroxidase and superoxide dismutase activities, but higher malonaldehyde content than in silty-loamy soil. K. candel seedlings at Mai Po grew better in light gaps than under a mangrove canopy. Light gap plants had relatively larger leaf area, specific leaf area, leaf number and biomass. Also, there was higher Chl content and lower Chl a/b ratio in leaves of 1.5 years old K. candel plants growing under the mangrove canopy than those growing in light gaps, as well as higher leaf nitrate reductase activity and higher root activity. POX activity and SOD activity in leaves of K. candel seedlings growing under light gap conditions were slightly, but not significantly, higher than in leaves of seedlings growing under the mangrove canopy, resulting in higher MDA content.香港城市大学资助项
