本文利用中尺度模式WRF-ARW(Weather Research and Forecasting Model-Advanced Research WRF)(Version 4.0)对海南岛不同天气条件下的典型海风锋个例进行了高分辨率数值模拟,通过设计局地城镇化的敏感性试验,重点分析了海南岛沿海城镇化对海风锋推进的影响及其可能机制。研究结果表明:海南岛沿海城镇化造成的海风锋结构差异是热力作用和动力作用共同影响的结果;城镇下垫面的摩擦效应与城市热岛的增强阻碍海风向内陆推进,减弱了海风锋途经地区的降温增湿效应,造成海风锋位置相对滞后;而城镇化所引起的高海陆热力差异增强了海风风速及海风辐合,同时导致海风锋前的垂直上升气流和海风环流厚度也明显增强。海风锋发展不同时期,城镇化对海风锋的推进影响有所不同。海风锋发展初期,海陆热力差异引起的推动作用与摩擦效应的阻碍作用相抵消,导致海风锋的推进无明显影响;海风锋发展强盛阶段,城镇化条件下内陆城市与非城市之间的热力差异有所增强,阻碍了海风锋向内陆推进,导致海风锋内陆渗透距离减小。不同天气条件下城市化对海风锋推进的影响有所不同,相比于晴空天气,多云天气下城市与非城市的热力差异稍强,加强了城市热岛效应对海风推进的阻碍作用,导致海风锋滞后距离稍远。此外,当土地利用类型更换为城镇后,净辐射与陆气间交换能量减少,导致其潜热通量显著减小,感热通量值变大,从而升高了下垫面温度,增强了海风的垂直上升运动,进而造成边界层高度的升高。

1903—1906年间,章太炎的进化观发生了鲜明的“断裂”,在《訄书》时期,章太炎认同达尔文、斯宾塞的进化论;至《俱分进化论》时期,他提出了善恶苦乐并进的俱分进化观,并把“俱分”进一步推扩为“文明”的定语;到《民报》时期,特别是在《齐物论释》中,批判线性进化观背后的理论根源逐步呈现出来,表达为“齐文野”的思想旨趣及对目的论文明观的深刻反思,对进化概念本身的批判实则是对诸如文明、进步等观念被用以将强权和暴力合理化、合法化、合目的性的危险的格外警惕,这是理解章太炎一以贯之之道的方便法门。

Mo基合金作为先进核反应堆的包壳等堆芯结构材料的候选材料,其高温抗拉强度仍是制约其在先进核反应堆领域应用的瓶颈之一。本文通过收集Mo基合金的成分及抗拉强度等数据,并对数据进行相关性分析及重要属性的筛选,采用贝叶斯优化卷积神经网络的回归模型,构建了Ti、Zr、C、N等关键成分与Mo基合金抗拉强度的关联性,获得针对Mo基合金高温抗拉强度的性能预测。结合相关性分析以及建模预测分析得出:Ti、Zr、Re、La_(2)O_(3)有利于Mo基合金高温抗拉强度的提升;N和Si不利于Mo基合金高温抗拉强度的提升。后续通过分析双元素或者三元素组合共同影响抗拉强度变化,可以得出在特定温度条件下,Mo基合金抗拉强度达到一定范围的成分设计方案。
