查询词典 data point

The title and bill of material in engineering drawings are important data source for product data integrated management. In order to reuse the CAD data, the paper presents an effective method for extracting part information from existing engineering drawings. Through analyzing the format of title and bill of material, several shape-position characteristics of tables are summed up from the view of macro-layout and microstructure. A new method to automatically extracting drawing information based on cell-grid and feature-point is proposed along with its algorithm principle and implementation steps. A software package based on the method mentioned above is developed and used in practice.

1引言工程图是工程设计的主要成果和制造加工的主要依据，CAD软件的广泛应用使得传统上对于纸质图纸的管理模式转变为对大量电子文件的管理模式·由于文件系统在实际应用中不能适应复杂大规模的管理模式，已经出现了各种各样的图档管理系统[1]·工程图中包含的零件信息在表现形式上体现纸格式的标准化为批量提取数据提供了可能性·作为计算机处理的对象，图纸信息自动识别成为数据管理和系统集成的一项关键技术·当前CAD管理系统所处理的数据对象比较复杂，面临由不同企业使用不同的绘图软件生成的图纸，其中的标题栏和明细栏或者由软件自动生

本文根据激光扫描数据二维网格的组织形式，三维点的邻域关系直接体现在距离图像象素点的邻域关系上，因此对应点周围的点也有可能产生新的对应点，所以采用在已知对应点的邻域内局部搜索新的最近的点对，提高搜索的效率。

This study conducted a secondary data analysis based on the data from 1999 Survey of Health and Living Status of the Middle Aged and the Elderly in Taiwan, provided by the Bureau of Health Promotion, Department of Health, R.O.C.. The study subjects were elders over 65 years old, and the number of valid samples was 2890. The data were analyzed with descriptive statistics, one-way ANOVA, Chi-square test(X2), Independent-Samples t-test, point biserial correlation, the Pearson product-moment correlation, logistic regression analysis, multiple regression analysis and hierarchical regression analysis.

本研究乃是使用行政院卫生署国民健康局人口与健康调查研究中心执行之「台湾地区中老年身心社会生活状况长期追踪调查系列」1999年调查资料进行次级资料分析，研究样本为年满六十五岁以上之高龄者，有效样本数为2890人，针对所得的资料，以描述统计、单因子变异数分析、卡方检定、独立样本t检定、点二系列相关、皮尔森积差相关、逻辑回归、多元回归分析及阶层回归分析等统计方法进行分析。

It can edit the disaster map element selected including of adding ,querying propertiy data,zooming out,zooming in the map element and so on..systemic establishing solves the segregative fact between the geography position of disaster point and the propertiy data.lt unites them,realizes the mutual consult between the map and data,infinitely increasing the work efficiency.

可以对选择的灾害图元进行编辑，包括对应属性数据的入库、查询、图元的放大、缩小等。系统的建立较好地解决了灾害点地理位置与其属性数据相分离的事实，它将二者统一起来，实现了图数互查，极大的提高了工作效率。

We led the density function into the data structure as the weight, and use dense micro-cluster to describe the arbitrary-shaped clusters in data streams. In addition, we propose candidate core-micro-cluster and isolated micro-cluster synopses to maintain and distinguish the potential micro clusters and isolation point in data streams.

我们把密度函数以权值的形式引入数据结构中，并利用核心微簇描述数据流中任意形状的簇，并提出候选核心微簇和孤立微簇结构分别用于维护并区分数据流中潜在的核心簇和孤立点。

Forecast conclusion from prognosticating model abot river water quality may conflict with existing data of environmental monitoring,because it doesn't import existing data of forecast point In allusion to this condition, to import parameter of existing data may make forecast conclusion approach fact

河流水质预测模型使用的参数未引入预测断面现状监测结果，使预测结果可能与现状监测结果发生矛盾。针对这一情况，通过对预测模式的推导转化，在模型中引入污染源现状源强和预测断面现状监测浓度，将预测结果同现状监测结果联系起来，使预测结果更贴近实际

Taking Yanhe as an example, the distinct transition point of flood season runoff time series by the impacts of human activities has been detected by way of mathematical statistics analysis. And meanwhile, based on the datum before distinct transition point, the forecast model is set up only with the data series before the distinct transition point. The difference between the value derived from the equation and the observed value is right the influence on flood season runoff induced by human activities.

以延河流域为例，采用数理统计方法推估获取人类活动影响下汛期径流时序的显著转折点，以显著转折点前的数据建立预测模型，对比分析汛期径流量的实测值与预测值，其差值即为人类活动对汛期径流的影响程度。

This paper aimed at the Daqing region based sauce, sweet paraffin base crude oil, the main tasks and objectives will be: 4 million tons / year, 330 days a year, total starts, top of the tower to take heat, the first mid-back to take heat, second heat to take the middle back the distribution of 5:2:3, based on the given crude true boiling point distillation data and products Engler distillation data to calculate the product of various complex decision to cut the program data to calculate the product yield, full-tower heat balance calculation, rendering the whole tower of steam , liquid load distribution.

本文设汁主要针对大庆地区低硫石蜡基原油，主要任务及目标为：400万吨/年，按每年开工330天计，塔顶取热、第一中段回流取热、第二中段回流取热分配为 5：2：3，依据所给的原油实沸点蒸馏数据及产品的恩氏蒸馏数据，计算产品的各物性数据决定切割方案，计算产品收率，进行全塔热平衡计算，绘制全塔汽、液相负荷分布图。

When GPS data is displayed on a GIS map,logically the v ehicle point should be displayed on the roads.But because of the effect of error s,there are warps between the true vehicle point and the displayed point o n the map.

AVL系统中GPS信号在GIS地图上显示时，由于各种因素的影响，存在很大的偏差，对这种偏差的校正是十分必要的。

It can control the signal light with its internal project; also the user can modify the project by the control panel. And the outstanding point is that the intelligent traffic signal machine has the function of long-distance stakeout and control. Namely the intelligent traffic signal machine can transmit the real time traffic data to the upper computer and display the data on computer. The upper computer can modify and transmit the traffic data to the signal machine, improving the efficiency of the traffic control. The system realizes the function of communication by the TCP/IP protocol, and the capability is very good in reliability and real time.

本信号机能够运行内部的固有方案控制交通信号灯，同时可以通过键盘面板对方案进行修改，其突出特点是具备远程监控功能，即信号机能够实时将路口交通方案信息反馈给监控中心并在主控界面显示出来，监控中心可根据路口实际情况对现行交通方案进行修改，通过以太网下传给路口信号机，改善交通流量控制。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.
