查询词典 simulated data

Direct difference is sensitive to noisy data, so a threshold limitation is given, which can not only filter the result from noisy data but also pick edge points up according men's desire. On the other hand, artificial intelligence is used for segmentation in reverse engineering. Because the essence of segmentation is clustering similar characteristics and self-organizing feature mapping is one function of neural network, SOFM network is used for segmentation in the thesis, coordinates and normal of data points is took as the characteristics vector.

第二种方法，基于双向角度微分的边点提取法，针对三维正交模型采用基于截面线的方式组织数据，此方法比基于曲率半径方法更简洁，不用进行曲面拟合，大大提高了计算速度；计算过程中由数据点的直接差分逼近微分，但直接差分对数据误差敏感，为此，本文提出了阈值过滤的方法，一方面过滤了数据误差在计算结果中引起的噪音，另一方面可以按照设计意图控制边点的提取；来决定是否提取光滑交接的边点。

Point data is reorganized by generating index list respectively for geometric coordinates, texture coordinates and normal vectors. Triangular facet data is reorganized by collecting the faces with the same material attribute and generating triangle strip. Texture image data is reorganized in the format of DDS.

采用对几何坐标数据、纹理坐标数据和法线向量数据分别建立索引列表的方式重组点数据，通过集中存储相同材质面片和生成三角形条带来重组三角形面片数据，采用DDS图像压缩格式重组纹理数据。

The data a GetChunk call returns is assigned to variable. If Size is greater than the remaining data, the GetChunk method returns only the remaining data without padding variable with empty spaces. If the field is empty, the GetChunk method returns Null.

此方法取回的数据赋值给一个变量，若Size参数大于还需要取出的数据，则该方法返回剩余数据且并不在该变量后添加空格，若字段为空，则该方法返回NULL值。

Meanwhile, new observation operators are designed for routine observational data, and background error covariance is also calculated. Currently, the m3DVAR system is able to assimilate all the conventional observations data, such as sounding, surface and ship data, etc.

重新构造各种观测算子，并考虑了质量场和风场之间的平衡约束关系、背景误差协方差结构，实现对探空、地面资料、船舶报等常规观测的同化。

In this paper, for the data character of exploring and developing area in oil-area, I propose a sub-area, multi resolution and level model and create effective management mechanism on stratum grid data organization with index managing and organizing data linear octonary trees.

本文针对油气田的勘探、开发领域的数据特点，提出了分块的多分辨率层次模型，结合线性八叉树索引管理和组织数据，建立有效的地层网格数据组织管理机制。

I will make full use of simple data to demo online and offline access to data management data.

我将尽量使用简单的数据来演示在线获取数据和离线管理数据。

This project have done an in-depth data mining to the data of circuit breaker on-line working conditon monitoring system, and implement some effective circuit breaker on-line working conditon monitoring data analysis diagnose methods, promote the development of the analysis and research of other devicess on-line working conditon monitoring in the substation too.

本课题对断路器在线监测系统的数据进行了深入的数据挖掘，研究并实现了一些比较有效的断路器在线监测数据分析诊断方法，更对变电所其他设备的在线监测数据开展分析研究作出了有益的探索。

The data has been compare for test data and the soft can be used to the study of H.M.Cyclones by the RSM model Of Onflow , the predicted results fit well with test data and the new method has been found out which the study of H.M. Cyclones is used by.

试验结果证明，选用RSM湍流模型可以对旋流器流场进行较全面准确的数值模拟，为从理论上对重介旋流器进行深入研究提供了一条新的途径。

Scanning each character in the expression to separate and record operators, operational symbols and data types of operators, when expression being correct in syntax, recording interpreter executive order based on precedence of operator, a general expression interpreter is designed. The interpreter not only is used for numerical value and string computation, but also is easy to extend its functions, and when batch converting data, it could catch run error and continue to successive data.

2通过对公式的一次扫描，记录操作数、操作符号和操作数的赋值特性，并在语法正确的情况下，记录公式基于算符优先级的解释执行顺序，设计了通用公式解释器，它不仅可以进行数值运算、字符运算，而且可以对使用的函数库方便地进行扩充，在批量进行数据转换时，可以记录运行时错误，而不影响后续数据的执行。
