On the aspect of urban spatial distribution DM: Adopting the conception model of combination of location and attribute, the author brings spatial coordinates, spatial relationship and attribute character into the unitive model of spatial computation, studies city's land suitableness evaluation and the method of spatial clustering in division of urban function districts and brings forward the arithmetic of classification layer. Aiming at land spatial optimization allocation, the author puts forward SGA. In this arithmetic selection, crossover and mutation operator are progressed on the space.

在城市空间分布数据挖掘方面:采用空间—属性一体化概念模型,把空间坐标、空间关系和属性特征纳入到统一的空间计算模型,分别对城市土地适宜性评价和城市功能区划分中的空间聚类方法进行了研究,并提出了一种分类图层的平滑算法;针对城市土地的空间优化配置,提出了一种空间遗传算法,该算法中的选择、交叉、变异算子都是在空间上进行的;对多要素离散空间场之间的相关性测度,定义了一种基于信息熵的规范的相关指数,并给出了计算方法。

A new scheme of target discrimination in SAR images, consisted of frames, models and algorithms, is proposed. Under such a scheme, a global frame, combining orderly the algorithm based on feature extraction and that based on knowledge, is then proposed. Moreover, in the method of target discrimination based on feature extraction, a "loose-coupling" model is given. The existing features are chosen and three new features about the contrast are given under the "loose-coupling". Meanwhile, an algorithm of feature selection based on Genetic Algorithm is also modified to solve the problem that the existing algorithm can not evaluate the goodness-of-features comprehensively. The weighted quadratic distance discriminator is designed to improve the performance of target discrimination. Finally, a method based on the knowledge of target groups to remove clutter false alarms is also given.

The 46 ears classify into three groups on the basis of hearing threshold level,and classified into four groups on the basis of different disorders.Results The amplitude and reproducilbiity decreased as the hearing loss increased.

选择经耳镜检查、纯音听阈及声导抗测试确诊为中耳病变,纯音气导听阈不超过30 dB HL的46只病变耳及对照组正常28耳进行TEOAE测试,病变46耳分别按不同听阈水平及不同病变分组,并对其结果进行分析比较。

Methods One hundred and twenty cases (165 ears) of tinnitus and/or hearing loss were differentiated into five syndrome patterns according to the theory of traditional Chinese medicine: invasion of wind-heat, liver-fire up-stirring, stagnation of phlegm-fire, kidney-essence deficiency and weakness of spleen-stomach. Hearing threshold of pure-tone, function test above hearing threshold and matching of tinnitus frequency and loudness were carried out in all cases and the data were analyzed by SPSS statistical software.

方法]选择具有典型中医证候表现的耳鸣耳聋患者120例(165耳),经传统方法辨证为风热侵袭、肝火上扰、痰火郁结、脾胃虚弱、肾精亏损5个证型,分别进行纯音听阈测试、阈上功能测试、耳鸣频率及响度匹配,数据经SPSS软件进行统计学处理。

Restrain thrombocyte to release 5-HT and prevent Ca channel 'of thrombocyte experimen are chosen to carry out the pharmacodynamics research. Also analysis the PK-PD model.

The Markov forecast model, time series method (triple exponential smoothing method and a combined of triple exponential smoothing method and Markov model) and stepwise regression forecast method were choosed, and the basic principles and processes of the three models were analyzed and compared. Based on above, the three methods were used to predict population dynamic of Cricetulus barabansis and Meriones unguiculatus. The characteristic, accuracy and applicability of three methods were analysed and compared. The results showed that,(1) Markov model belongs to a middle-long time forecast model, and the result was interval forecast, but it reached the requirement of forecasting the harmful population dynamic of rodents. Through the forecasted population dynamic of Cricetulus barabansis and Meriones unguiculatus in 2004, the results were accurate; this meant that Markov model was a good forecast model to Cricetulus barabansis and Meriones unguiculatus population.

选择马尔可夫链预测模型、时间序列分析法(三次指数平滑法、三次指数平滑法和马尔可夫链预测模型的组合预测法)和逐步回归预测法,对这三种模型的基本原理、模型的构建过程进行对比分析,在此基础上用此三种方法预测了黑线仓鼠和长爪沙鼠的种群数量,并对三种方法的特点、预测的准确度和适用范围进行了比较分析,结果表明:(1)马尔可夫链预测模型属于中长期预测,预测的结果为区间预测,但对于害鼠种群数量的预测来说已经达到要求,通过对2004年黑线仓鼠和长爪沙鼠种群数量的预测,预测的结果都比较准确,这说明对于预测黑线仓鼠和长爪沙鼠种群的数量动态,马尔可夫链模型是比较好的模型。
