His proposal created a native graph data type that looked a bit like dictionaries , but allowed for storage of triples to represent a graph 他建议创建一种本机图( native graph )数据类型,这种数据类型看起来有点像字典,但是考虑到了用三元组的存储来表示图。
In this paper , the main frame of the graph data collection system of dmas is provided , the basic principle of the hardware system is analyzed , and the functions of automatic focus , automatic sampling , and picture joint are described at length 本文主要介绍了dmas智能化铁谱分析系统的图像数据采集系统的基本框架,分析了系统的硬件原理,详细描述了自动聚焦、自动采样、图像拼接等具体功能的实现。
On the base of current spatial data structure , management technology of gis is discussed in the second chapter . using serialized file organizes graph data , and using relation database manage property data and linking data of graph and property data 第二章在现有gis空间数据组织及空间数据结构基础上,探讨了gis数据管理方法;即图形数据由序列化的文件管理,属性数据及图形和属性数据的连接数据采用关系数据库管理。
Dmas graph collection system adopts the technology of closed - loop automatic control ; has capabilities of displaying and storing the graph data and characteristic of portable , strong anti - jamming , small - volume . 2 , the research on dmas fault diagnostician system 使dmas图像采集系统具有全自动控制能力,实现了整个系统的闭环控制;具有高性能的自动采集能力;具有显示和存储能力;具有较强的抗干扰能力;具有体积小、轻便灵活的特点。
( 3 ) this paper independently developed a especial memory database for reactive optimal software with the visual c + + 6 . 0 fundamental database class . the storage of data is implemented through serialize and the management of data is implemented in memory to minimize the data storage and increase the speed of read / write . all of those are foundation of acquisition and transmission of text data and graph data ( 3 )本文结合visualc + + 6 . 0内部的基本数据库类,独立开发了无功优化软件的专用内存数据库,数据的存储通过序列化机制来完成的,数据的管理则完全在内存中进行调度,从而减少了数据的存储量,提高了数据的读取速度,为本文无功优化软件的本文和图形数据的提取和网络传输提供了良好的基础。
Based on theory and software of gis , the thesis do some application research on the application of geographic information system to transportation planning , which is pertinent to characteristic of transportation planning and combined with actual circumstance of traffic zone and road network in certain city . during the process of transportation planning and by theoretical base and software development system of gis , basal database is founded , which consists of spatial database and attribute database in information system of transportation planning . the system provides corresponding tools for editing and modifying graph data and can flexibly do some operations such as adding , deleting and modifying and so on 本论文就地理信息系统在交通规划中的应用进行了研究,在gis的理论基础和软件开发平台的基础上,针对交通规划的特点进行了gis的二次开发,结合某城市主城区交通小区和道路网络的实际例子,建立交通规划信息系统的基础数据库,包括空间数据库和属性数据库,并提供相应工具对图形数据和属性数据进行编辑和修改,可以非常灵活地对它们进行增、删、改等操作,对交通规划的前期预测、交通需求预测、交通分配及规划方案的评价进行了探讨,最后,对交通规划成果进行可视化输出,如制作各种专题图,从而将地理信息系统和交通规划结合起来,形成交通规划信息系统,将交通规划中具有空间特征的信息进行可视化表达,为信息利用者提供直观、清晰、全面的信息表达方式,提高了交通规划决策的科学性和合理性。
This software uses some important technologies such as the digital - format graph , mapx - integrated graph technology , integration of property - data and graph data and the analysis of the internet route and etc . in this essay , from the characteristic of the city route net to the relationship between the routes , a reasonable top - modal of the net is constituted 然后介绍了gis技术的一个应用实例?数字化城市电子地图软件,主要介绍了开发过程中使用的一些关键技术如数字地图的格式、 mapx集成地图技术、数据库的管理、属性数据和几何数据的结合、网络路径分析等。
The measurement system can automatically control the movement of servo motor and communicate with vna through gpib bus to setup the measurement variable automatically , measure the phase of s parameter . it also can progress the measurement data on the background , display the results by graph data , store them in the data files 系统自动控制伺服电机的运行,对测试探头完成指定的移动定位;通过gpib总线与矢量网络分析仪器通信,自动完成相关测量参数的设置以及s参数的相位测量;对测得的数据进行后台处理,将结果以图形、数据文件的方式显示、保存。
After setting up the bank , it involves in linking graph data with attribute data , spatial analysis , establishing the appraisal model of gold resources . subsequently , the thesis fulfills an ore deposit location assessment and gold ore resources assessment by correctly applying mathematical models and numerical methods , and bring forward assessment outcome and work suggestion 地学空间数据库建立后,即进行图形数据与属性数据连接,开展空间分析,建立资源评价模型,并正确应用评价数学模型和计算方法,进行矿床定位预测和资源潜力评估、提出评价成果和工作建议。
