基于FR-ResNet的车辆型号精细识别研究
车辆型号精细识别 卷积神经网络 残差结构 特征重用
2024/1/23
车辆型号精细识别的关键是提取有区分性的细节特征.以"特征重用"为核心,以有效提取车辆图像细节特征并进行高效利用为目的,提出了一种基于残差网络特征重用的深度卷积神经网络模型FR-ResNet(Improved ResNet focusing on feature reuse).该网络以ResNet残差结构为基础,分别采用多尺度输入、低层特征在高层中重用和特征图权重学习策略来实现特征重用.多尺度输入可...

为解决600 MW示范快堆（CFR600）事故分析和工况设计中的实际问题，自主开发了钠冷快堆系统程序FR-Sdaso，其建模范围包括堆芯、一回路、二回路、三回路、四回路和事故余热排出系统，主要物理模型包括点堆模型、单通道堆芯热工模型、多区钠池模型、四区蒸汽发生器模型等核岛设备或部件分析模型，汽轮机、凝汽器、给水加热器、除氧器等常规岛设备采用集总参数模型，泵、阀门、管道及控制体等采用通用模型。对程序...
钠冷快堆系统分析程序FR-Sdaso衰变热计算模型开发与验证
衰变热 系统分析程序 FR-Sdaso 程序验证
2021/1/11
反应堆停堆后的余热导出是反应堆的重要安全功能之一，停堆初期余热由裂变功率和衰变热构成，停堆后期余热主要取决于衰变热。本文开发了应用于钠冷快堆系统分析程序FR-Sdaso的衰变热计算模型，该模型可考虑裂变功率和功率历史的影响。通过与ANSI/ANS-5.1—2005标准和SAS4A/SASYS-1程序对比进行了模型验证。FR-Sdaso程序的计算结果与ANSI/ANS-5.1—2005标准的最大相对...
系统分析程序是开展反应堆安全分析的重要工具之一，也可用于开展系统瞬态实验过程的分析。法国凤凰堆（Phenix）在停运之前开展的自然循环实验是钠冷快堆领域非常重要的系统瞬态实验，为研究钠冷快堆的瞬态特点提供了很好的参考。为分析此实验过程，利用自主研发的系统分析程序FR-Sdaso对凤凰堆进行建模，对其自然循环实验开展计算分析，并将主要参数的计算值与实验值进行了对比分析。结果表明，FR-Sdaso可较...
