差示扫描量热仪测量影响因素分析及其不确定度的评定

本文以杭州盘古自动化系统有限公司提供的MDSC100型差示扫描量热仪为测试仪器,根据JJG 936-2012《示差扫描热量计检定规程》使用热分析标准物质In和Sn对仪器温度和热量性能进行测试和评价,对测量影响因素进行分析探讨,并对其测得值的不确定度进行评定。

伤残鉴定中智能障碍评定的多因素的临床研究

目的:为客观评定智能障碍程度,探讨影响智能障碍评定的多因素。方法选定366例颅脑损伤患者分别进行韦氏智力测验和鉴定专家评定,对其结果和影响因素进行分析,并将其结果进行分析。结果脑外伤所致智能障碍占大部分比例,脑外伤程度与所致伤残等级关系密切。影响韦氏智能测试结果有被鉴定者的主观因素与客观因素。智力测验结果与专家鉴定结果存在显著差异。结论智力障碍评定受多种因素影响,有测量试验本身的影响因素和测验者规范化操作、熟练程度的影响等,还包括被测者的主客观因素的影响。

Pre-evaluation on stability of proposed expressway embankment with existing geothermal regulation measures in permafrost regions

Embankment stability is the primary problem for the expressway construction in permafrost regions.The proposed Qinghai-Tibet Expressway(QTE)is planned to construct along the Qinghai-Tibet Project Corridor.Confronted with harsh environmental condition and intense heat exchange between earth and atmosphere,it is necessary to predict and evaluate the stability of the proposed QTE.In this study,the factors affecting the embankment stability are analyzed firstly.And then,a scheme for the stability evaluation of the embankment is established.Finally,the evaluation scheme is used for the pre-evaluation of the stability for the proposed QTE with different geothermal regulation measures(GRMs).The results indicate that the influencing factors include climatic environment,permafrost property,engineering condition and geological condition,and among them,engineering condition and permafrost property are the main influence factors for embankment stability.The stability of the proposed QTE varies greatly in the different geomorphological regions.The application effect and contribution to embankment stability of the existing GRMs are different,and using GRMs cannot completely overcome the influence of various factors on expressway stability.In the construction process,different GRMs should be adopted depending on the geomorphological environment where the embankment is located to ensure the embankment stability.

基于ROMI的住院精神分裂症患者服药依从性及相关因素研究

目的 探讨住院精神分裂症患者服药依从性及其影响因素。方法 以住院精神病患者为研究对象，采用药物影响因素评定量表（ROMI）作为评定工具，以半结构式访谈的形式评估入院 3周后患者对于抗精神病药物的心理资料，分析ROMI评分与患者人口统计学资料及临床资料的相关性，预测ROMI各因素对依从性的影响程度。结果 患者的人口统计学资料（年龄、学历、工作状态、是否有人监管、住院付费方式）及临床资料（用药种类、病程、住院次数）与 ROMI评分无关（P＞ 0.05），药物不良反应与 ROMI不依从原因分量表得分呈正相关（P＜0.05）。患者遵从专家指示、感受到药物对日常生活的益处、害怕复发、家人或朋友对于服用药物有正面意见等因素在促成依从的主观因素中影响较大（P＜0.01），患者认为药物不良反应较为缓和、药物可以帮助实现个人目标、与医务人员有良好关系是促成依从影响较普遍的因素（P＜0.01）。结论 药物不良反应带来的苦恼是不依从的主观原因中影响较普遍的因素，患者遵从专家指示、感受到药物对日常生活的益处、害怕复发、家人或朋友对于服用药物有正面意见等因素对药物依从性影响较大。
