The DM642 External Memory Interface expands two pieces of MT48LC4M32B2 (4M*32 bit SDRAM) and a AM29LV33C (8M bit FLASH). SDRAM is connected to the 64bit data bus of EMIF, can read/write 64bit data at every cpu cycle, be used to store program, data and image.

单片机采用了Cygnal公司的C8051F020，它使用了CIP-51微控制器内核，与MCS-51TM指令完全兼容。C8051F020通过I2C总线和通用I/O口与DM642相连接，接收I2C偏差数据，并通过单片机内部的两个全双工UART输出。

An isolated point s statistic excluding method is proposed in this paper to eliminate crassitude error in clouding data, which include plenty of oddity data. The method based on the distance between two neighbour points can eliminate the data beyond normal distribution. A error limitation of angle and chordal highness method is used to filtrate clouding point.

针对大量含奇异点的数据点云，本文提出了剔除粗大误差的孤立点统计排异法，该方法根据对相邻点距离的统计，剔除在正态分布以外的点；对大量数据的精减，利用角度和弦高的最大允许偏差法进行点云精减。

本文以共反射面元水平迭加的原理为基础，全面、系统地研究了山区弯线地震反射工程地质勘探技术，包括，弯线设计、数据采集、数据处理、资料解释等，并介绍了两个应用实列。

In the respect of data adaptability, MARS is relatively more suitable to credit score model building based on current credit data in China, for the classification accurate rate of General Cross Validation Value is better than based on data from UK.

在对数据的适应性方面，相对来说，MARS方法更适用于基于中国个人信用数据建立个人信用评分模型，其最终模型的GCV值分类准确率都好于基于英国个人信用数据得到模型。

The electronic heating evaporator in the high-side gravity recirculation system in ANSI/ASHRAE 64-2500 standard is replaced by a new type plate evaporator which is more effcient and energy-saving, because the cold water outlet from the evaporator that is used to heat the cryogen can be used once again to cool the air in the air inlet trunk; an air processing unit is designed in the lab design, so to imitate all kinds of weather in each season in every location of China at any time the test is being made; the data selection system can send all the data in the test to the computer at one time, and to reduce the cost of the test some data which is more stable are read manually through traditional meters if this can not sacrifice the precision of the test.

本文的设计中用效率更高的新型板式换热器代替了原ANSFASHRAE 64——2500标准中压缩驱动循环系统中的电加热蒸发器，加热冷剂后得到的低温淡水还可以用于冷却进气通道中的空气，不仅提高了效率，而且更加节能；实验室方案中增加了空气处理系统，可以实现随时对全国各地各季节的空气状态进行模拟，方便实验的进行；采用数据采集系统将数据整体采集到电脑中方便数据处理，而且对于变化频率不高相对较为稳定的数据采取传统仪表进行人工读数，在保证测试结果准确性的前提下降低了成本。

If the current receiver location is outside the current data cell range, a hand-off controller (202) searches for a new data source (104) encompassing the current receiver location coordinates and having an associated data topic matching the current topic.

如果当前接收机位置是在当前数据小区范围之外，切换控制器(202)搜索一覆盖当前接收机位置坐标并具有与当前主题匹配的相关数据主题的新数据源。

To obtain the likelihood function indicating the uncertainty of observed information, noisy data is firstly expressed by a set of data vectors instead of a single vector, and then transferred to probability density curve defined in model space through confidence value defined in data space.

我们将数据向量的概念扩展为数据向量的集合，通过引入数据空间内的信赖度，把数据噪声转移到模型空间的概率密度函数上，即获得了反映数据本身的不确定性的似然函数。

Basing on the 3D image data compression and in accordance with the structure characteristics of 3DLCS scanning data that the scanning data set of 3D surface can be considered as a curve set in 3D space, the thesis extends 2D curve Splitting compressing method to the 3D space and presents a 3D curve compressing method based on the curve compression and the color information compression. The 3D compressing effect is better.

在三维图像数据压缩方面，根据3DLCS的扫描数据结构特点（即可以将三维表面扫描数据集看作一个空间曲线的集合），将平面曲线压缩中的Splitting方法推广到三维情形，提出了一种基于曲线压缩和彩色信息压缩的三维数据压缩方法，取得了较好的压缩效果。

Based on the fact that managing changes of data is the most neglected problem in the data warehouse metadata management, the paper proposes a model that is based on CWM and repository technology and can manage metadata of data warehouse.

针对元数据的变更管理是数据仓库元数据管理中最容易忽略的问题，本文提出一种基于数据仓库元数据管理系统的元数据管理模型。
