From the angle of engineering application, this article analysed the corrosion characteristics and damage causes of the current structural used concrete in the region of Hangzhou gulf, on the basis of on-site survey of all the Marine concrete projects in that area. Taking HPC used in Marine as research objective, this article put great emphasis on the influence of the composition cementing material system to concrete performance, and make a preliminary probe into the action mechanism of the composite effects of various mineral materials in improving the performance of concrete by laser measuring size machine and EMPA. Through experiments, the article discussed how chloride ingression in concrete will be effected by such factors as exposure time, chloride binding, environment temperature, stress and cracks conditions; and also analysed the symptoms of these factors in the model of concrete service life prediction by conference to all related research reports both home and aboard. On the foundation of abovementioned research, this paper brought up an engineering model of service life prediction of marine concrete, which is based on chloride-induced corrosion.
本文从工程应用的角度,在对杭州湾地区既有海工混凝土工程作实地调研的基础上,研究分析杭州湾地区既有海工混凝土结构的腐蚀特点和破坏原因;以海工高性能混凝土为研究对象,着重研究复合胶凝材料体系对混凝土性能的影响,并应用激光粒度仪、EMPA等分析手段,就复合胶凝材料的作用机理进行初步探讨;试验研究混凝土暴露时间、胶凝材料对氯离子的吸附、环境温度、应力和裂缝状态等因素对混凝土中氯离子迁移运动的影响,并结合国内外相关研究报导,探讨这些因素在混凝土使用寿命预测模型中的表征;在上述研究基础上,提出以氯离子侵蚀为基础的海工混凝土使用寿命预测的工程应用模型。

According to Meese's exchange rate model in 1986, in this paper, we modified Meese's (1986) model and suppose the Interest Rate Parity is untenable, the risk premium factor and real exchange rate parameter are considered, and the Purchasing Power parity doesn't follow random walk, we derive our modified equilibrium model. Base on the State Space Model, we try to estimate bubbles and risk premium which are unobservable variables by Kalman Filter to test which one is or both are the main factors that to cause the real assets price biased from the market fundamental price.
本文是以Meese(1986)所决定的汇率模型为基础,但Messe一文并未讨论到风险溢酬的问题,故本文为了克服此一缺憾,而假设未抛捕的利率平价说(uncovered interest parity,UIP)不成立,以加入风险溢酬因子,且更进一步假设偏离购买力平价理论(purchasing power parity,PPP)不服从随机漫步,若如此则顺利将实质汇率变数纳入於模型中,重新建立均衡汇率模型,为了验证本文所创立的模型,实证方法以状态空间模型为基础,运用卡门滤波器递回法来估计不可观察的变数,以观察台湾的外汇市场上是因泡沫现象还是风险溢酬造成资产价格偏离市场基要价值或是两者皆是造成实际资产价格偏离市场机要价格的因素。

Thirdly, in order to manage these data better, the paper advances the organization methods of data of commixed Database of Geo-spatial Framework model by integrating some advanced database technologies such as RDBMS and the Spatial Database Engine, namely on the basis of database and the data of Geo-spatial Framework divided in a preceding part of this paper, it describes layer-delaminating, block-dividing, slice-connecting, map-dividing and BLOB etc. to organize spatial data, including DLG, DOM, DEM, and thematic data, taking example for the data of urban planning. At the same time it also realizes integrated management of these data.
然后,本文以管理这些地理空间框架数据为主要目标,集成关系数据库管理系统以及空间数据引擎等相关技术,提出了地理空间框架混合数据库数据组织方法,即以地理空间框架数据库为基础,以分类后的地理空间框架数据为对象,通过采用分层、分块、连片、分幅以及大二进制对象等方法对基础空间数据(包括数字线划数据、数字正射影像数据、数字高程模型数据)和专题数据进行统一组织,并实现了这些数据的关联一体化管理。
