Gaoya dianqi, 2017 高压断路器的运行状态评估是指导高压断路器状态维修、提高其运行可靠性及保证电力系统安全稳定运行的重要手段。文中依据物元可拓理论和证据融合理论建立了一个高压断路器状态评估模型。首先对高压断路器状态评估进行物元分析,通过构造关联函数并计算评估指标的关联函数值,仅凭关联函数值的正负就能初步确定评估指标是否异常;然后依据集对分析理论对评估指标初步所处状态等级的不确定性进行处理,得到评估指标的等级关联度,并将评估指标的等级关联度进行修正作为信任分配函数 ...

基于GB/T 20984的信息安全风险评估模型与综合评价方法
四川大学学报. 自然科学版, 2010 在GB/T 20984的基础上建立了信息安全风险评估的数学模型;通过定义"风险熵",以定量描述各风险域及系统整体风险状态的不确定性程度,揭示信息安全风险随系统复杂程度而递增的规律;对信息安全风险评估和系统风险的整体评价进行了理论归纳.

Exploring English Language Learners’ Vocabulary Knowledge and Usage When Speaking
International Journal of Applied Linguistics, EarlyView.ABSTRACT Vocabulary forms a fundamental component of speaking ability, as it enables speakers to convey meaning accurately, fluently, and effectively. Although the relationship between vocabulary and speaking has been investigated to some extent, gaps remain in understanding the link between learners’ vocabulary knowledge and their speaking proficiency,

L2 Chinese Grammatical Acquisition and Processing: A Substantive and Methodological Review
International Journal of Applied Linguistics, EarlyView.ABSTRACT This study presents a systematic review of 92 empirical studies on Chinese as a second language (CSL) in grammatical processing and development, synthesizing their substantive foci and methodological characteristics. The results reveal consistent scholarly attention to cross‐linguistic topics, with less focus on features that are distinctively

Gaoya dianqi, 2018 针对当前电力变压器套管绝缘状态评估中各评价参量存在复杂性和不确定性的问题,文中应用集对分析方法对变压器套管进行绝缘状态评估。首先选取用于套管状态评估的指标,对评估结果进行等级划分并制定响应策略,采用层次分析法和熵权法融合的综合赋权法来确定各评估指标的权重,构造联系度数学表达式来描述评估指标与状态等级之间的关联程度,建立起集对分析状态评估模型。实例计算分析表明,基于集对分析方法和综合赋权的状态评估模型能够有效反映变压器套管的绝缘状态,评估结果可为变压器的状态检修提供有效参考。

, 2008 近年来,生态风险评估已被人们所重视,但到目前为止,生态风险评估还没有一套完整的方法体系。以我国最大的内陆河——塔里木河下游为研究区,将遥感、地理信息系统等技术手段与模糊数学方法相结合,根据ERA框架和层次分析思想建立塔里木河下游植被的生态风险评估指标,运用模糊综合评判的方法进行塔里木河下游植被生态风险的遥感定量评估,并在评估结果的基础上进行可视化分析。结果表明:在流域生态风险评估缺乏有效的定量评估方法的情况下,Fuzzy集合论与AHP方法结合的模糊综合评判方法是可行的,具有较高的科学性;运用遥感 ...
