【目的】研究z指数在期刊评价中的效果。【方法】以SSCI收录的信息科学和图书馆学期刊为例,计算分析了目标数据的总发文数量、总被引频次、篇均被引频次、一致性指标η、h指数、p指数和z指数,实证研究了z指数应用于期刊影响力的评价效果。【结果】z指数相较于h指数以及p指数更加适合于综合评估期刊学术影响力的质量因素、数量因素和被引分布情况。【结论】利用z指数评价期刊有助于激励期刊发表高水平论文,z指数具有较好的灵敏性和区分度。但z指数在期刊学术影响力评价中存在不能区分施引文献影响力大小等缺陷。

目的探讨时刻APP对ST段抬高型心肌梗死(STEMI)患者再灌注救治流程的优化作用。方法根据就诊时间将中国胸痛中心认证数据管理云平台收录的急诊就诊STEMI患者分为对照组(n=19)和观察组(n=23)。对照组按胸痛中心原流程救治,并通过填写胸痛中心急性胸痛诊治时间节点记录表录入D2B时间。观察组采取以时刻APP分析为指导的改进流程进行救治,并通过时刻APP录入D2B时间。结果流程改进后,观察组从诊断到启动导管室和导管室激活到患者到达2个时间段达标率显著优于对照组(均P<0.01),患者D2B时间的总达标率高于对照组(P<0.05)。结论以时刻APP为指导的救治流程改进可以提高胸痛中心STEMI患者D2B时间达标率,进而改善患者预后。

太原理工大学学报 2024年

The new energy generation represented by wind power is the most realistic strategic choice to achieve the goals of carbon peaking and carbon neutrality. To absorb renewable energy electricity in power grids a new probabilistic evaluation method for available transmission capacity in transmission systems is proposed based on joint cumulants， and a decision model for risk available transmission capacity based on expected quantiles is proposed accordingly. As a vital component of ATC calculation， the transmission reliability margin (TRM)， as a reserved transmission capacity， reflects the impact of uncertainty factors on transmission capacity. However， in traditional calculation methods， TRM is determined through deterministic or probabilistic methods， which is difficult to reflect the risks brought by large-scale wind power consumption to ATC and cannot meet the requirements for transmission capacity risk management. Firstly， to address the issue that the cumulative method requires variables to be independent of each other and cannot consider the correlation of wind power output， a joint cumulative method combined with FGM Copula function is proposed to characterize the correlation of wind power output; Secondly， for the probabilistic assessment of available transmission capacity， a probabilistic assessment model for available transmission capacity is established by combining the partition integration method and the Comish Fisher expansion; Finally， in response to the problem that decision methods based on value at risk only consider the probability achieved at the tail of the probability distribution and cannot describe the risks generated throughout the distribution， a risk available transmission capacity index based on expected quantiles is proposed， and its evaluation process is proposed. Verify the feasibility and practicality of the proposed indicators and models through case analysis.

以双王金矿KT9矿体采空区为研究背景,通过建立采空区三维FLAC3D模型,研究分析了采空区周围岩体应力场和位移场的分布情况。结果表明:采空区周围岩体内不存在拉应力场,压应力主要集中于1~4线之间,且在2线处最为严重,导致该处岩体变形量最大,但采空区总体表现为相对稳定,据此提出了后期矿柱回采和空区处理方案。
