查询词典 database access

This thesis,aim at the portability,makes the design of residential supervising system modulized and a small scale.It combine the microcontroller to process data through internet and store input signal in the database.In addition,it need the basic internet environment rather than database and web server.In this thesis,the sensor module and other hardware are also designed portably in order to set up easily.

因此本研究以「可携式」为目标，针对一般居家活动监测系统进行模组化、缩小化设计，并结合单晶片网路伺服器作资料处理与传输，以个人化资料库软体作资料储存与处理，仅需基本家庭网路环境，不需专用伺服器主机，而且感测器及软体亦均设计为可携式，期望能以简单、高弹性、客制化的方式，依个人需求装置於居家环境中。

This paper studys the the interactions between solution of primary minerals ofthe reservoir sandstone, the deposition of authigenic mineral, and the formingmechanism of secondary porosity in Upper Paleozoic reservoirs in Ordos basin withthe modeling theory of Water-Rock Interaction, builds the correspondingthermodynamics database and dissolution experiment database, and provides thecomparable and quotative data for the Water-Rock Interaction modeling research ofreservoir rock.

本论文将水—岩相互作用模拟(即热力学理论模拟计算和溶解模拟实验相互结合的方法)用于鄂尔多斯盆地上古生界碎屑岩骨架组分的溶解、自生矿物的沉淀及其与次生孔隙形成机制之间关系的研究，建立了相应的热力学数据库和溶解实验数据库，为沉积盆地储集岩的水—岩相互作用的模拟研究提供了可对比与借鉴的基础资料。

In this thesis, we have proposed the algorithms of performing of three improving types, can improve the efficiency of prospecting of the unusual fluctuation database , so the improvement type of a thesis performs algorithms and will not need to rescan the whole database each time when there are newly-increased materials, the majority only needs to scan the newly-increased trade materials, in order to improve the efficiency of prospecting.

在本论文中，我们提出了三个改良式的演算法，第一个为Apriori演算法来动态探勘，其二为使用布林演算法为基础进行动态探勘，最后为以布林运算为基础之FP-tree的动态探勘，可以提升异动资料库的探勘效率，因为在过去的资料探勘技术中，在探勘关联规则的过程}式演算法当有新增资料时将不用每次都要重新扫描整个资料库，绝大部分只需要扫描新增的交易资料，以提升探勘效率。
