Flat geotubes are widely used for coastal structures such as seawalls, breakwaters and sightseeing groins, etc.. However, the understanding of the stable mechanism involved in the wave-structure interactions should be deepened, and one of the important work is to clarify the stress state of the structure under the wave action. In this article, wave force acting on coastal structures made of flat geotube is experimentally investigated. The required drag, inertia and lift coefficients are especially analyzed from the results of hydraulic model experiments specially designed for geotube structure. Several types of structures made of flat geotubes under wave action have been tested in order to understand the stress state of the geotube fixed to force transducer within different structures. Experimental results show that the wave-induced forces on the instrumented geotube are markedly influenced by wave elements. Meanwhile, the magnitude of horizontal force of adjoining geotube is different at the same time.

人文城市建设是我国新型城镇化战略的重要组成部分,也是城市超越物质性和实用性之上的本质追求。建设城市文化场景是实现人文城市的有效路径。本文在场景理论框架下,采集中国31个城市的83种文化舒适物数据,结合专家打分计算各项文化舒适物的场景得分,形成3个一级维度和15个二级维度的文化场景评价体系,并以模式识别方法区分城市的场景模式,筛选其特征性维度。结果发现,31个城市可分为四类文化场景模式,即魅力型场景、本土型场景、理性型场景和表达型场景,四种模式在地理空间上呈清晰的条块状分布。本文认为中国城市文化场景反映出鲜明的时代特征,文化特质、自然环境、区域规划是影响文化场景的主要因素。

文化产品兼具商品属性和社会意识形态属性,能有效提高国家经济实力和文化影响力。基于联合国教科文组织公布的2004-2013年十年间六个文化产品出口领域的面板数据,选取六个文化产品出口大国进行分析。采用主成分分析(PCA)和偏最小二乘判别分析(PLS-DA)进行模式识别,找出文化产品出口的典型模式及影响因素。PCA分析显示六国均具有各自的文化产品出口模式,且大体可分为三种模式;PLS-DA对三类模式进行进一步区分,所构建模型的R2X(cum), R2Y(cum)和Q2(cum)值分别为0.995,0.863,0.829,模型稳健性好(R2=0.869,Q2=0.850)。这三类文化产品出口模式分别为以英国、美国、德国为代表的"传承发展模式",以法国、新加坡为代表的"创新发展模式",以及以中国为代表的"工业制造模式"。造成出口模式差异的主要因素为视听与互动媒体、书籍与报刊、表演与庆典等领域。在模式分析的基础上提出,我国应进一步调整文化国际贸易的结构,拓宽文化产品类型,理顺国际贸易渠道,从以工业输出为主导的文化出口大国,向以价值输出为核心的文化出口强国转化。

长岭断陷经历侏罗纪火石岭组—白垩纪营城组沉积时的断陷期、白垩纪登娄库组—白垩纪末期的拗陷期、第三纪至今的反转期三大演化阶段,发育6个次凹、13个二级构造带,构造带走向多为NE向或近SN向,构造带的形成及演化具有相似性,均为营城组末期形成,后期经历三次张扭改造,但张扭改造程度有强有弱。本文通过研究长岭断陷地质结构、构造特征、火山岩特征及分布,认为长岭断陷规模大、天然气资源丰富,总体上处于天然气初期勘探阶段。火山岩体发育,储层物性较好,具有良好的保存条件,长岭断陷深层具有良好的天然气勘探前景。

在皮埃尔·布迪厄的实践社会学理论中,以实践为中介,将场域与惯习相互关联,最终形成紧密相关的互动结构。区域科技创新系统作为一个场域,对场域中各个创新主体的惯习有着重要影响,而惯习反作用于场域,指导各个创新主体形成以自身为主导的子场域来更好地进行实践创新活动。根据场域-惯习理论,从多维创新主体视觉出发对科技创新进行了分析,明确了科技创新主体内涵;在把握创新子场域的主体——企业、高校、科研机构、政府以及科技服务中介等科技活动主体现状与惯习动态的发展过程中,研究了五大主体在科技创新活动中各自发挥的主导效用以及相互之间关联性、互补性和协调性模式;基于对创新子场域的主体主导效用分析,建立了评价模型,可以为现实中的科技创新场域提供一种便于操作的惯习方法。
