恒定

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。

Patterns in Nature: Sand Strange creatures slithering up from the Empty Quarter desert floor in the Arabian Peninsula are really a network of barchan dunes—sculpted by winds that over time strike the sand from a consistent direction.

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。

Orthogonal subset is extracted from orthogonal geometry by collecting all traces that have a shot line and a receiver line in common, therefore the two lines are vertical bisectors. An orthogonal subset is single-fold coverage of a 3-D dataset.

在正交子集中，各种规则干扰，如面波、声波、折射以及由地面不均匀体产生的散射，在三维空间上，形成以震源或散射点为顶点的锥形体，线性噪音为从圆锥顶点辐射出的直线，具有恒定的视速度。

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.

针对该明暗条纹消除方法，介绍了常规的基于图像处理的&Laplacian噪声消除法&，并提出了一种新的解决方法&恒定参考源法&，通过对比这两种方法，认为在难以保证黑体控温精度的情况下，关闭黑体的温控功能是一种更好的解决方法，对于红外扫描仪的遥感应用具有一定的指导意义。

The research results show as follows: if the gas pressure is fixed, the seepage velocity of briquets drops at first and rises later with increasing axial stress, and increases after peak stress.

研究结果表明：恒定瓦斯压力时，在某一围压下，峰前渗流速度随轴向应力先减小后缓慢增大，到达峰值应力后，随轴向应力的减小而增大。

The De for the two relaxation pro- cesses decreased strongly at the beginning of curing process and then became almost constant at longer curing times.

前二的放松的De在治疗过程初强烈被减少的cesses然后变得几乎恒定在更久的治愈时间。

Results Positive selected codons were different in groups corresponding different periods.

结论分析结果提示流感病毒HA1序列在进化过程中的正向选择位点并非恒定，而是在不同年代中存在更替趋势。
