 [PDF]

张佳, 建军
Statistics and Applications (SA) , 2014, DOI: 10.12677/SA.2014.34022
Abstract:
本文以小额贷款公司主要的客户群体中小企业作为研究对象,立足于公司日常的信用贷款业务,基于Logistic与Probit模型进行风险评估实证分析。在小额贷款行业专家的帮助下,采取头脑风暴法获得建立模型所需的八项指标。这八项指标作为模型的自变量,从内容上可分为两部分,一部分描述借款人个人情况,另一部分衡量企业经营状况。在昆明高新科创小额贷款公司数据支持下获得模型结果。在面对具体的贷款业务时,可以通过相应模型计算客户信用风险得分,最终做出是否予以贷款的决策。经检验,研究成果可行、有效。
SMEs (small and medium-sized enterprises) as small loan companies’ main customer groups are objects of study in this paper. Based on the companies’ day-to-day credit loan business, Logistic model and Probit model are applied to this empirical analysis of credit risk assessment. Adopt brainstorming to get eight required indicators with the help of experts on microcredit industry. These eight indicators as independent variables in the model can be divided into two parts ac-cording to content. One part is used to describe borrower’s personal circumstances and another part is used to measure companies’ business conditions. Data from Kunming KC small loan company are fitted with these two models. In the face of a specific loan, calculate the corresponding credit risk score and then make the decision. Upon examination, results of this study are feasible and effective.

Abstract:
目的:了解抗血栓泵对预防下肢静脉血栓形成的作用,为临床护理实践和护理科研提供信息。方法:对比其他药物和物理方法预防下肢静脉血栓形成,抗血栓泵在预防下肢静脉血栓形成的安全性和医护心理接受程度更佳。结果:抗血栓泵模拟人体行走运动时腿部肌肉收缩,加快下肢血液流动,防止血液淤滞,从而减少了血栓的形成。从而达到预防深静脉血栓的目的。结论:间歇式压力充气泵是一种物理性非介入型的治疗仪器。它使用方法简单,减少了护士的工作量,病人也易于接受。
Objective: To investigate the effect of antithrombus pump on prevention of venous thrombosis of lower limbs, and to provide information for clinical nursing practice and nursing research. Methods: Compared with other drugs and physical methods to prevent venous thrombosis of lower limb, the antithrombus pump in the safety of the prevention of lower limb venous thrombosis and the psychological acceptance of health care is better. Result: Antithrombotic pump mimics human leg muscles’ contracting when walking, to speed up the lower limb blood flow, prevent blood silt up, thus reducing the formation of blood clots, so as to achieve the goal of prevention of deep vein thrombosis. Conclusion: The intermittent pressure air pump is a kind of physical nonintervention therapy apparatus. It is simple to use, reducing the workload of nurses, and is more acceptable to patients.
TCP congestion control based on RTT phase-plot
基于RTT相位图的TCP拥塞控制


重庆邮电大学学报(自然科学版) , 2009,
Abstract: 异构无线网络中传统TCP协议性能大幅度下降.在不增加开销的情况下,利用三维相位图划分RTT所处空间区域来区分丢包原因,提出了一种新的TCP拥塞控制机制(TCP- BRP).仿真结果表明,TCP- BRP增强了对拥塞和随机差错的区分能力,满足公平性要求,有效地提高了在异构无线网络环境下TCP的性能.

上海市普陀区现制现售水自动售水机现况调查

中国公共卫生 , 2009, DOI: 10.11847/zgggws2009-25-10-64
Abstract: ?随着人们生活水平的提高和对健康需求的增加,各种可直接饮用水应运而生,其中一种新型的以现制现售方式售卖纯净饮用水的自动售水机,水质处理设备与自动售货机结合为一体,通过采用反渗透、纳滤或超滤等制水工艺,对市政自来水的源水进行消毒灭菌〔1〕。为加强现制现售水监督管理,参照上海市卫生局于2006年7月颁布的《上海市现制现售水卫生监督管理办法》,于2007-2008年,对上海市普陀区内所有的现制现售水自动售水机进行现况调查,并以随机抽样方法对其中部分自动售水机出水水质进行检测分析。现将结果报告如下。
反语生成和理解的认知心理探究

湖南工业大学学报(社会科学版) , 2011,
Abstract: 从认知语言学的角度切入,探讨反语的心理运作过程和规律。在反语生成和理解过程中,人的反向思维能力和人的联想能力,特别是对比联想能力分别起到了至关重要的作用。对其研究有助于加深我们对反语的认识和理解。
上海市某小区管道直饮水卫生状况调查

环境与职业医学 , 2015,
Abstract: :[目的]通过调查上海市普陀区管道直饮水供水小区现况,针对目前管道直饮水供水小区存在的安全隐患,提出管理对策,以进一步加强该区管道直饮水卫生监督管理,并为《上海市生活饮用水卫生监督管理办法》及相关地方标准的制定提供参考。[方法]采用现况调查的方法,调查该区2013年所有管道直饮水供水小区的制水机房卫生状况,使用的涉水产品,消毒产品索证情况,卫生管理制度制订和落实情况,水质自检和自检结果公示情况,供水管网设计及回水消毒情况,水质检测仪表设置情况等,并对调查结果进行分析。[结果]该区17个管道直饮水供水小区仅76.5%的水处理设备能提供有效的涉水产品卫生许可批件;制水机房设置与生产工艺卫生要求不匹配,其中94.1%的机房面积不足50m2;水质自检能力良莠不齐,检测项目8~14项不等,自检频率最高的小区为每日自检一次,64.7%的小区仅每月自检一次;日常巡查养护能力有待加强,频率较高的达6次/d,频率较低的为每2天巡查1次,巡查内容多为水流量等设备运行情况;反渗透制水工艺的设备出水耗氧量与纳滤工艺比较,差异有统计学意义(P<0.05);无论采用哪一种制水工艺,设备出水与用户管网远端水的耗氧量差异均有统计学意义(P<0.05或P<0.01)。[结论]卫生行政部门在加强日常性监督管理及法规知识宣传培训力度的同时,应尽快建立管道直饮水相关的法律法规和技术体系,将管道直饮水纳入卫生许可监管,使管道直饮水的建设和管理更加规范。同时,有关科研部门应继续优化和完善直饮水的工艺方案和设计参数,发展水质在线监测,切实提高管道直饮水的水质安全和供水效益。

安徽早三叠世巢湖龙前肢比较及分类学意义
Comparison of the Forefin of Chaohusaurus and Its Taxonomy Meaning, Early Triassic, Anhui Province


- , 2016, DOI: 10.13209/j.0479-8023.2015.077
Abstract: 摘要 由于标本少和保存情况不好等原因, 对巢湖龙(Chaohusaurus)解剖学特征缺少详细描述, 安徽地区巢湖龙的种级分异尚存争议。经过对比研究北京大学地质博物馆馆藏的采自安徽巢湖的鱼龙标本与相关模式标本, 基于骨骼形态及腕骨骨化程度等方面的差异, 将标本分为两类。将研究标本及相关模式标本等进行聚类分析, 结果表明存在两个类群。将前肢骨骼数据作图, 显示存在两条生长序列, 该结果推翻了之前的巢县陈氏龙和小巧陈氏龙均为龟山巢湖龙后出同物异名的结论。据此推断, 巢湖马家山地区的巢湖龙可能存在两个物种。厘清巢湖龙的种间关系有助于全球早三叠世原始鱼龙类的对比研究, 并对探讨鱼龙的早期演化具有十分重要的意义。
Abstract Due to the low number and bad preserved condition of the specimens, the anatomical features of Chaohusaurus have not been described in detail. As a result, there is a controversy about the membership of this genus. Based on some new specimens housed in the Geological Museum of Peking University, there are two styles of the forefins compared with the holotype, with differences in skeleton morphology and the mesopodial ossification. The cluster analysis of those specimens shows that there are two groups. Measurements of the forefins suggests that there are two trendlines, so the conclusion that Chensaurus xiaoxianensis and Chensaurus faciles are junior synonyms of Chaohusaurus geishanensis is not appropriate. There are at least two species of Chaohusaurus in Chaohu. Clarifing the diversity of this genus is of significance to the comparison of the Early Triassic ichthyosaurs in the world and the study of the early evolution of basal ichthyosaurs.
