Zhongshan Daxue xuebao. Yixue kexue ban, 1996 通过磁带式２４ｈ连续动态心电监测，对１８６例确诊心肌梗死连续病例及５０例非冠心病者进行Ｑ－Ｔｃ分析，并与传统ＳＴ段指标相比较。Ｑ－Ｔｃ延长检出心肌缺血的敏感性与特异性分别为９２．５％与９６．０％；ＳＴ段指标诊断心肌缺血的敏感性与特异性分别为６９．４％与１００％。两组敏感性差别有高度显著性（Ｐ＜０．０１）．两组特异性差别无显著性（Ｐ＞０．０５）。结果提示：Ｈｏｌｔｅｒ检测中Ｑ－Ｔｃ的延长能作为心肌缺血的判断指标之一。

Gaoya dianqi, 2015 为了快捷准确地识别复合绝缘子的憎水性等级,提出了基于图像处理与RBF神经网络的绝缘子憎水性识别方法。首先,对图像进行直方图均衡增强、自适应中值滤波处理;然后,利用二维Ostu阈值法对图像进行分割;最后提取4个与绝缘子憎水性相关的特征量,以这4个特征量作为输入向量,以相应的憎水性等级作为输出向量,通过训练得到优化的RBF神经网络识别模型,并用于绝缘子憎水性等级的识别。试验结果表明,该方法能够准确识别绝缘子的憎水性等级,总识别率高达90%,准确度达到了实际应用的要求,为在线检测绝缘子憎水性奠定了基础。

Leveraging an Unhappiness Lens for Smarter Policies
Policy Studies Journal, EarlyView.ABSTRACT Traditional policy research has largely focused on enhancing happiness or well‐being, privileging positive outcomes as the primary metric of success. We argue that a systematic focus on the drivers of unhappiness—rather than solely on happiness—offers a complementary analytical framework that can uncover hidden societal deficits and broaden ...

Zhongguo shiyan zhenduanxue, 2008 目的探讨金标法（DICA）和酶标法（ELISA）测定结核抗体在结核病诊断中的临床价值。方法用上述两种方法分别检测结核病患者336例,非结核性呼吸道疾病60例,健康体检者50例。结果结核病组DICA法和ELISA法测定结核抗体的阳性率分别为88.4%和71.1%,特异性分别为95.0%和91.7%;非结核性呼吸道疾病组阳性率分别为5.0%和8.3%;健康对照组DICA法全部阴性,ELISA法有3例阳性（6%）。结论DICA法的敏感性和特异性均高于ELISA法,且ELISA法存在一定的假阳性 ...

, 2007 针对分散性粘土遇水分散流失的不良性质,应用碎块、针孔、双比重计、孔隙水可溶盐和交换性钠质量分数5种试验方法,研究了西安市黑河水利枢纽工程粘土心墙土料的分散性。研究认为,土料大部分属于非分散性粘土,少部分属于分散性粘土,分散性粘土的蒙脱石与伊利石的质量比值较高;在采用黑河水冲蚀针孔时,分散性粘土有表现为非分散性的趋势;大坝建成后的坝体原状土样属于非分散性粘土。结果表明:蒙脱石与伊利石的质量比值是判别粘土分散性的重要指标,水质对土的分散性具有显著影响;分散性粘土与非分散性粘土合理混合使用可降低粘土的分散性 ...

Impacts of Sex,Gender Role and Gender Belief on Undergraduates Personality Traits
, 2007 通过对北京市5所大学552名大学生的调查,探讨性别、性别角色类型和性别观念类型对大学生人格特征的影响。结果表明:(1)性别角色和性别观念比生理性别对大学生人格特征的影响更大。(2)双性化大学生具有更多积极的人格特征; 传统型大学生具有较高的面子; 反传统型大学生具有较高的宜人性和较低的面子; 冲突型大学生具有较高的神经质、防御性和较低的宜人性、灵活性 ...

How Do Policy Narratives Evoke Emotions? An Appraisal‐Theoretic Approach
Policy Studies Journal, EarlyView.ABSTRACT Research on policy narratives acknowledges the crucial role that emotions play within communication and sense‐making. Especially the Narrative Policy Framework (NPF) has placed emotion at the center of attention and stressed that affect‐imbued stories are key for how individuals make sense of the world and navigate through the policy process ...
