查询词典 datum

By theory analyzing and example calculation and comparison, the conclusion is obtained that the traditional inferential method can be applied in the design flood peak flow calculation, yet it cannot truly express the runoff process of the rain drainage inlet, the instantaneous unit hydrograph depending on the real and actual datum is different to be used in the runoff discharge hydrograph calculation, and the no linearity reservoir means and the isochronal method have some physics base and its parameters easily evaluated and its runoff discharge hydrograph still more is close to practice.

5通过城市雨水地表汇流特性及计算方法的理论分析、实例计算和对比得出：传统推理法可应用于城市设计洪峰流量的计算，但不能真实地反映雨水口径流流量过程；瞬时单位线法等对实测资料有较大依赖，难以应用于城市径流流量过程线的计算；非线性水库法和等流时线法的径流流量过程线接近实际。

Therefore, we just supplement and improve the use of altimeter setting and the datum level as used by the aerodromes where the transition height or the transition altitude and transition level have been set up in the Administrative Rules on Air Traffic of China's Civil Aviation.

鉴此，只对《中国民用航空空中交通管理规则》有关高度表拨正值的使用，以及划设过渡高或者过渡高度和过渡高度层的机场使用的基准面进行补充和完善。

Pressure figures from this ISA are used in calibration of barographs, because although the real atmosphere varies from day to day, for calibration purposes a set of internationally agreed figures are needed so that all calibrations are to the same datum, whether or not such figures correspond to 'true' height on a given day.

来自 ISA 的压力数字，用来校准自动记录式气压计﹙ barographs ﹚，因为真正的大气每一天都不同。为校准的目的，需要一套国际同意的数字是，使所有校准是相同的基准，无论这些数字是否对应某一天的'真正的'高度﹙ 'true' height ﹚。

Successively with dataflow picture, data dictionary, function structure chart various kinds of datum analyticl system take of system in network analysis.

在系统的设计中，详细的展现了系统的各个功能模块。所需的数据库表及表字段。菜单的设计等。

Historically, datums have been based on ellipsoids that best represent the geoid within the region the datum is intended to map.

历史上，大地基准面一般基于与制图区域大地水准面最接近的地球椭球面构建。

By looking up lots of datum, we selected ASP as developing tool, SQL2000 as database developing tool, empoldered a student document management system based on ASP which uses B/S mode.

经过分析，我们使用 ASP 作为开发工具，SQL2000作为后台数据库，开发出了以B/S为模式的基于ASP的学生信息管理系统。

By looking up lots of datum, we selected ASP as developing tool, SQL2000 as database developing tool, empoldered a student document management system based on ASP which uses B/S mode.

摘要学生档案管理系统是典型的管理信息系统，其开发主要包括后台数据库的建立和维护以及前端应用程序的开发两个方面。

On the basis of getting the true and reliable monitoring datum, the methods of diagnosis algorithm based on state predicting are also discussed in this paper. A method based on BP artificial neural network is presented. A diagnosis model is also designed and emulated. The results of the emulations show that the algorithm is obviously better than that of the traditional three-ratio method, and the algorithm can accurately makes good judgments on the faults base on qualitative and quantitative analysis.

在获得真实可靠的监测数据的基础上，还进行了运行状态预测的故障诊断方法的探讨，提出了基于BP神经网络的故障诊断方法，建立了一个诊断模型，并对该模型进行了仿真，仿真结果表明该算法明显优于传统IEC三比值法等故障诊断方法，能够比较准确地定性和定量地对故障做出判断，为电力运营部门提供有用的决策依据。

Firstly, we simulate the signal received by OTHR in each antenna according to the real working condition, and save the signal datum in file. Secondly, we develop the signal processing program and the visual users interface. Thirdly, we utilize the simulation system to analyze Linear Frequency Modulated Continuous Wave OTHR system and Binary Phase-coded Continuous Wave OTHR system. Finally we compare the performance in suppression of interference of these two kinds of OTHR system.We achieve two aims in this simulation system.

本文首先根据OTHR的工作环境模拟OTHR各个阵元接收的回波信号，并将其保存为数据文件；然后根据OTHR的系统结构，编写信号处理程序，并给出可视化用户界面；最后利用OTHR仿真系统，对二相编码连续波和线性调频连续波这两种发射波形的OTHR作抗干扰性能分析。
