Electronic map of MapInfo is introduced into the environment of object oriented by the use of Map X 4.0 module. The operations such as dynamic add, delete and edit of objects can be done real-time dynamically by operators in the environment of object oriented on the present diagram of polder region. At the same time, the spatial-data and attribute-data of irrigation district are managed separately. The spatial-data is used by the file system, whereas, the attribute-data exist in the relevent database. The figures and database are related through the only ID number in order to realize two-way inquiry, so that, the polder region river system planning data are collected automatically. Moreover, this system make the great use of GIS advantage in storing and annalising data to automatically organize files needed in river network calculation , adopt one-dimensional unsteady flow model , so as to lay out height of river levee .
把GIS技术引入水系规划,通过MapX4.0组件把MapInfo电子地图调入面向对象编程环境,使操作人员能在面向对象环境中对圩区现状图进行实时动态操作,包括对操作对象的动态添加、动态删除、编辑等;同时,将空间数据和属性数据分开进行管理,空间数据用文件系统管理,属性数据采用数据库管理,通过建立唯一ID号进行数据联接,将图形与数据库进行关联,实现属性到图形或图形到属性的双向查询,从而实现了圩区水系规划部分数据的自动采集;另外,本系统充分利用GIS存储与分析数据的功能,自动生成河网水力计算所需的文件,采用一维非恒定流模型进行河网水力计算,为确定沟道堤顶高程提供依据。

Assessment of Gastric Sensitivity, Compliance and Accommodation: The stomachs were distended isobarically by barostat via a double-lumen polyvinyl tube with an adherent plastic bag, gastric sensitivity was measured by perception threshold and gastric compliance was calculated as the slop of the pressure-volume curve.
胃敏感性、顺应性和容受性的检测:用barostat及双腔气囊导管对胃进行等压扩张,以患者的不适阈代表胃对扩张的敏感性,以压力-容量曲线的斜率反映胃顺应性;将气囊压力恒定为MDP+2mmHg,以进食前后胃内平均容量的差值来反映近端胃的容受性。7。

A normal method to eliminate these stripes is presented. And then a new method based on a stable reference source is presented and validated. And the two methods are compared. The result shows that it is better to turn off blackbody controller when it is very difficult to control blackbody temperature precision, and it is of significance for remote sensing application of infrared scanner.
