Basis Functions in Data Mining

在传统的统计数据分析和数据挖掘中，数据一般是时间序列、截面数据或面析 数据，我们把这些数据看成离散的且有限的，于是导致采用计量经济模型的数据分 析依赖很多的假设条件，有较强的结构约束。此外，传统方法忽视了这些数据的部 分函数特征，且一般要求数据的观测点和观测次数相同，而在实际中收集到的数据 很多时候并不满足这个条件。 函数性数据分析是从函数角度对数据进行分析，把函数性数据看作一个整体， 不要求观测对象的观测点和观测次数相同。与传统的分析方法相比，函数性数据分 析具有其自身的很多优越性。 函数性数据分析目前已成为统计学术界研究的热点之一，涌现了大量相关的理 论和经验分析文章。但...In the traditional statistical analysis and data mining, the data is generally time-series, cross-section data or panel data. We view the data as separated and limited, so that the analysis of econometric model relies on a lot of assumptions with structural constraints. In addition, the traditional methods ignore some functional characteristics of the data, and usu- ally require the data in th...学位：经济学硕士院系专业：经济学院计划统计系_经济信息管理学学号：1542006115086

Study on organochlorine pesticide and PCBs at surface water in Xiamen Harbour

利用GC -ECD对厦门西港 1998年 7月取得的 9个站位表层水体中的 18种有机氯农药 (HCHs ,DDTs等 )和 12种多氯联苯 (PCBs)进行分析。其中有机氯农药的浓度范围 6 .6 0～ 32 .6ng/L(其中HCHs:3.5 1～ 2 7.8ng/L ,均值 8.5 7ng/L ;DDTs:0 .95～ 2 .2 5ng/L ,均值 1.45ng/L) ,多氯联苯的浓度为 0 .0 8～ 1.6 9ng/L ,同国内外其他港口海区相比较 ,其污染程度相对较低。同时 ,对有机氯污染的分析表明 ,发现近年来仍有有机氯的污染输入 ,其农药的使用主要集中在六六六和滴滴涕上 ;多氯联苯和有机氯农药在厦门西港有着相似的分布及来源特征。organochlorine pesticides and 12 polychlorinated biphenyls(PCBs) at the sruface water in Xiamen Harbour were determined. The range of organochlorine pesticides was 6.60～32.60 ng/L, and the PCBs concentrations were 0.08～1.69 ng/L. Compared with the results of other harbor and estuaries, it showed that the contamination for organic chlorine pollutants was more slight than those of others. At the same time, it was found that organochlorine pesticides and PCBs have the similar geological destribution and resources.福建省自然科学基金!项目 (D9810 0 0 3

The trends and characteristics of organochlorines pollution in surface sediments of Xiamen Western Bay

利用GC ECD对厦门西港 1 998年 7月取得的 8个站位表层沉积物中的 1 8种有机氯农药 (HCHs,DDTs)等和 1 2种多氯联苯 (PCBs)进行分析 .其中有机氯农药的浓度范围ND(未检测出 )— 0 58ng/g(其中HCHs和DDTs的含量分别为ND—0 1 4ng/g与ND— 0 0 6ng/g) ,多氯联苯的浓度为ND— 0 32ng/g ,与 1 986、1 993年的厦门西港的分析结果相比较 ,污染程度明显降低 ;说明近年来的厦门的有机污染得到逐步控制 ,也与有机物随时间推移逐渐详解有关 ,分析表明多氯联苯和有机氯农药在厦门西港有着相似的分布特征 .The contents of 18 organochlorine pesticedes and 12 polychlorinated biphenyls(PCBs) in suface sediments from Xiamen Western Bay were analyzed by GC\|ECD. The range of organochlorine pesticides was ND—0 58?ng/g,and the PCBs were ND—0 32?ng/g.Compared with the results of Xiamen Harbor in 1986 and 1993, it showed that the pollution of organochlorines decreased gradually along the time, in Xiamen Harbor became and the contamination was more slightly than that of other Harbors or Estuaries. At the same time, it was found that the geological distributions of organochlorine pesticides and PCBs, also the HCHs and DDTs were similar to each other, which indicated that the polltion was cansed by a same source

Evaluation and Fate of the Organic Chlorine Pesticides at the Waters in Jiulong River Estuary

1999 0 6,对九龙江口 1 5个站位的表层水 ,1 3个站位的间隙水进行了 1 8种有机氯农药的测定结果表明 ,有机氯农药总含量在表层水中的浓度范围为 51 3～ 2 4 79ng L ;在间隙水中的浓度范围是 2 66～ 33355ng L .对不同有机氯的含量在各站位的分布特征进行了探讨 ,发现Methoxychlor(甲氧滴涕 ) ,EndosulfanSulfate(硫酸硫丹 ) ,Endrinaldehyde(乙醛异狄氏剂 )以及EndosulfanII(硫丹 ) ,Dieldrin(狄氏剂 ) ,Deta HCH和Beta HCH 7种有机氯农药在 1 8种有机氯农药中都占主要部分 ;九龙江口的六六六的含量顺序 :β >δ α >γ ;对于滴滴涕 ,表层水中的含量 :DDE DDD >DDT ;间隙水中的含量 :DDE DDT >DDD ,二者DDE的含量都在总DDTs的 50 %以上 ,说明环境中的DDTs主要降解为DDE ;九龙江口有机氯农药随着盐度梯度 ,在河口中呈去除趋势 ;且间隙水中有机氯农药比表层水中的浓度高 ,说明其倾向于吸附在沉积物颗粒上 ,其浓度差使得有机污染物可能通过再悬浮等过程从底层向上层迁移 .九龙江口的有机氯农药污染与其他港湾相比 ,污染水平相当 ,部分站位水质有机氯农药 (HCHs和DDTs)超过国家一类水质的标准 .Organochlorine Pesticides at the water(surface water and porewater) in Jiulong River Estuary were determined. The range of organochlorine pesticides at surface water was 51.3～2479ng/L, and the concentration in porewater was 266～33355ng/L. The results showed that the organochlorine pesticides were removed in the estuary and the sediments were the reservior of the organochlorine pesticides. Compared with the results of other harbor and estuaries , it showed that the contamination for organic chlorine pollutants in Jiulong River Estuary was similar to those of others. At the same time,the risk of organochlorine pesticides in the estuary was evaluated.1998年教育部重点项目、基金委资助留学人员短期回国工作讲学专项基金!项目联合资助 (4 9910 76 0 74

Present situation and development of acupuncture in the Netherlands

介绍针灸疗法在荷兰的发展历史、现状、针灸教育机构及协会、立法、应用等情况。针灸传入荷兰大约有400年,目前针灸在荷兰仅作为补充和替代医学之一,尚未通过国家立法;其发展以民间为主,缺乏正规的针灸医疗机构,教育机构也以私立为主;针灸虽未列入荷兰基本医疗保险范围,但作为保险公司提供的附加保险项目之一,其费用仍可得到部分报销。尽快建立正规的医疗机构,培养高素质的针灸师,促进国家对针灸的立法,将针灸纳入基础医疗保险范畴,是荷兰中医界目前亟待解决的问题。The development,present situation,educational institution and association,legislation and application of acupuncture therapy in the Netherlands are introduced.Acupuncture was introduced into the Netherlands about 400 years ago.At present,being one of the complementary and alternative medicine,acupuncture has not passed the national legislation yet.The nongovernmental source is given priority to the development of acupuncture and the educational institution is private.Even though acupuncture has not been listed in the basic medical insurance in the Netherlands,it becomes one of the additional items of the insurance company and its expenditure is reimbursed partially.The field of TCM in the Netherlands now is facing to the issues to be solved,including constructing the official medical institution,educating high-quality acupuncturists,promoting national legislation and adopting acupuncture into the basic medical insurance

复杂形状的疏水微通道的LBM模拟

随着微机电系统的发展和广泛应用,人们发现由于系统尺度的缩小,使得体系的面体比增大,在宏观系统中可以忽略的表面作用力在微尺度系统中变得不可忽视。宏观流体力学中经典的无滑移边界在微尺度系统中被证实不再适用。因此,液体在微米乃至纳米尺度构件中的独特的流动特性引起了人们的重视。目前,微流动的应用技术发
