摘要： Consider k(>= 2) independent populations pi 1,...,pi(k) such that an observation from population pi(i) follows a logistic distribution with unknown location parameter mu(i) and common known scale parameter sigma(2), i = 1,...,k. Let mu([1]) <= ... <= mu([k]) be the unknown ordered values of its and the population associated with mu([k]), be the upper extreme population (UEP) and the population associated mu([1]) be the lower extreme population (LEP). In this paper, we discuss a procedure on the lines of Liu [On a multiple three-decision procedure for comparing several treatments with a control. Austral. J. Statist. 39, 79-97] and Boher [Multiple three-decision rules for parametric signs. J. Amer. Statist. Assoc. 74, 432-437], for classifying k logistic populations by the location parameters as better or worse than a control/standard population. In the absence of any standard/control population, we propose a selection procedure for simultaneous selection of two non-empty random size subsets, one containing population associated with largest mean and the other containing population associated with smallest mean with a pre-specified probability P* (1/k(k-1) < P* < 1). The required selection constants to implement the proposed procedures are tabulated. Using these selection constants, the simultaneous confidence intervals for the parameters mu([i])-mu([1]), i = 2,...,k, mu([k])-mu([i]), i = 1,...,k-1, are constructed. A simple instructive numerical example is given. (c) 2006 Elsevier B.V. All rights reserved.

关键词： 检验批   验收   表格填写   验收制度  

摘要： 随着建设的高速发展,各个地方对工程质量重视程度不同,因此在结合实际进行操作时,不能熟练的按照检查验收的内容和方法进行检查验收。在中间阶段性验收时,发现检验批的质量验收记录,不够详细,也不够及时、真实和准确,达不到新版规范强化管理、过程控制的目的。因此,对检验批的质量验收,应该引起参建各方的重视,以提高检验批验收的操作水平。

关键词： 解不等式   应用题   不等式组  

摘要： 　　利用不等式解应用题的步骤与利用方程解应用题的步骤相似:即设未知数、列不等式(组)解不等式(组)、检验、写出答案.但是,同学们很容易忽略检验这一步骤.下面就举例来说明检验这一步骤的重要性和必要性.……

摘要： A chemometric analysis has been developed to emphasise the discrimination power of spectroscopic techniques such as near infrared, mid-infrared and visible spectroscopy. The combination of two spectral domains using outer product analysis (OPA) leads to the calculation of an outer product (OP) matrix. The representation of this matrix is called the "analytical fingerprint" of the samples and their classification is performed in the following steps. First, two different techniques are tested by subtracting the images one-by-one and the sum of all the elements of the resulting difference matrix gives a scalar, characteristic of the distance between the two images. Combining chemical analysis with image, processing techniques provides an original approach to study butters and margarines in relation to their fat content. Best results were obtained with the OP matrix built from NIR and visible signals following the use of city-block distance and average linkage. Samples were arranged in four groups: 100%, 82-75%, 70-59% and 38-25% w/w fat. The cophenetic correlation coefficient (validity of the cluster information generated by the linkage function) associated with these spectral data has a value of 0.973. Similar results were obtained using Ward's algorithm which generated four groups and a cophenetic correlation coefficient equal to 0.959. (c) 2006 Elsevier B.V. All rights reserved.

摘要： The probabilistic neural network(PNN) was applied in the recognition of cancerous stomach *** characteristic FTIR peak frequencies(including vas(CH3),vs(CH2),δ(CH2),vas(PO2-),v(C-O),vs(PO2-) and vs(nucleic acid(DNA,RNA),cell proteins and membrance lipids) from corresponding stomach cancer tissues were used as the input vectors of the PNN neural *** experimental results as follows: 1) when net parameter,spread,is 0.25～2.55,and the vas(PO2-),v(C-O),vs(PO2-) and vs(nucleic acid(DNA,RNA),cell proteins and membrance lipids) were employed as input vectors,PNN neural network exhibited the best performance with a mean accurate rate of recognition up to 96.2%;and when the spread between 0.2～4.60,and all the characteristic FTIR peak frequencies mentioned above were used as net input vectors,the PNN neural network exhibited a slightly lower performance with a mean accurate rate of recognition of 92.3%,while the PNN neural network performed very poorly when just v(C-O) and vs(PO2-) were used as input vectors with a mean accurate rate of recognition of 53.8%.2) In general,in comparison,PNN neural network should obviously be more excellent with respect to LVQ neural network(see ref.) in prediction and recognition of cancerous stomach tissues.

摘要： 近年来,我国农产品频频遭遇技术壁垒和绿色壁垒。商务部最新发布的数据显示:2006年,中国农产品出口达310.3亿美元,与2005年同期相比增长14.1%。但与此同时,我国有90%的农业及食品出口企业受国外技术性贸易壁垒措施的影响,每年损失约90亿美元。帮助农产品应对复杂苛刻的贸易壁垒,推动农产品出口的持续增长,关键在于做好农业标准化工作。对于这项艰巨迫切的任务,检验检疫部门大有可为。

关键词： 病案资料   法医   审查   伤者  

摘要： 目的探索病案资料在法医活体检验鉴定中的作用。方法将与伤者损伤有关的全部材料联系起来,并举例说明就病案资料与法医活体检验所见及调查材料等之间的联系,全面分析并进行综合审查。结果病案资料是法医活体检验鉴定中的重要文证资料,对法医能否准确作出法医学鉴定起着举足轻重的作用,也是检察法医文证审查的重要内容。法医在实际检案过程中经常会碰到一些伪假的病案,倘若不认真细致地对病案的客观性进行审查,就可能导致认定事实的错误,从而作出错误的鉴定结论,造成冤假错案。因此,法医对病案客观性的审查十分重要。结论规范病历书写,切实做好病案质量的监控,使病案资料在法医检验鉴定工作更具严肃性和科学性。

摘要： 我国合同法未对合同的法定书面形式的效力加以规定,致使存在不同看法。法定书面形式的效力应当从其种类、范围、立法目的来加以确定。在法律未明确法定书面形式的效力时,我们认为其主要起到证据的作用。
