He jishu实现对空间中子/伽马（n/γ）的精准甄别有利于空间辐射场的研究。传统的甄别方法受数据噪声影响较大，难以实现在星载探测器这样高噪声水平条件下进行n/γ甄别。为实现在不同噪声水平下n/γ的有效甄别，本研究提出了使用小波散射网络（Scattering Convolution Networks，SCN）结合MobileNetV4（MNv4）和Kolmogorov–Arnold Networks（KAN）模型的n/γ甄别的算法。研究选用Ø50 mm×50 mm的NaI（Tl ...

He jishu铅铋堆蒸汽发生器发生传热管破裂事故（Steam Generator Tube Rupture，SGTR）后，二次侧高压过冷水将喷放进入一次侧的高温铅铋熔融物中。该现象可能的后果有铅铋凝固，压力波造成堆内构件损坏以及蒸汽迁移进入堆芯引入意外反应性。为了研究该过程，上海交通大学先进核能系统实验室搭建了大型铅铋-水反应实验装置台架。在实验开始前，针对该台架预先开展计算流体动力学（Computational Fluid Dynamics，CFD）计算以认识实验现象并确定实验工况 ...

He jishu钠沸腾是钠冷快堆重大事故前的重要瞬态现象，进行钠冷快堆事故分析需要准确预测钠沸腾时的两相状态和冷却剂热力学参数。本文为钠冷快堆一体化分析程序ISAA-Na（Integrated Severe Accident Analysis code）开发了基于多气泡段塞假设的堆芯热工水力模型。使用ISAA-Na对高燃耗辐照堆芯（Cœur à Haut Bûrnup Irradiation，CABRI-BI1）失流实验进行了模拟和分析。与实验数据的对比表明，ISAA-Na相较于SAS4A、ASTEC ...

Frontiers in Neuroenergetics, 2010 Interpreting fMRI data relies on the assumption that hemodynamic responses reflect neuronal activity. Some recently reported results seem to suggest that this assumption might be less robust than what has been thought so far. Data by Schummers et al. (2008) suggest that hemodynamic responses depend on functional properties of astrocytes as mediators of

European Journal of Entomology, 2020 The progress in constructing a DNA barcode library for German Diptera as published by Morinière et al. (2019, Mol. Ecol. Resour. 19: 900-928) is appraised from a dipterists' perspective. The coverage of the diversity of German Diptera in terms of barcode
