Dizhen xuebao, 2018 本文通过多个震例的假定情形，讨论了地震破裂的有限性对地震早期预警系统布局设计的重要意义。分析结果认为，地震早期预警系统对地震减灾所能发挥的作用要远大于传统地震学视角下的预期。该观点深化了目前所认为的预警台站应该适当考虑非均匀布设的认识，强调在发生较大地震时，近断层区域密集布设的预警台站可能会使地震早期预警系统更加有效。

Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Conservation Biology, EarlyView.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

Attainment Pairing Effects on Cognitive Conflict in Technology‐enhanced EFL Cooperative Tasks
International Journal of Applied Linguistics, EarlyView.ABSTRACT This study examines how attainment pairing (high‐high versus high‐low versus low‐low attainment) impacts English as a Foreign Language (EFL) learner engagement during technology‐enhanced cooperative writing tasks. Seventy‐eight Chinese university learners formed 39 dyads (13 pairs per group) via Tencent Meeting.

高原地区器官剂量调制技术在CT平扫中对女性盆腔的保护价值及对图像质量的影响
Zhongguo shiyan zhenduanxue, 2022 目的 探讨高原地区器官剂量调制(ODM)技术在女性盆腔CT平扫中对性腺区辐射剂量和图像质量的影响。方法 收集临床需要行盆腔CT平扫检查的女性患者200例，随机分为实验组和对照组。对照组100例，采用常规盆腔CT平扫，实验组100例，开启ODM技术进行盆腔CT扫描，记录患者性腺区域前、左、后、右4个方向管电流、平均管电流、容积CT剂量指数(CTDIvol)、剂量长度乘积(DLP),并计算有效剂量(ED)。由两位资深影像科医师采用5分法对两组CT图像质量进行主观评分 ...
