为定量揭示城区和郊区O_(3)前体物对O_(3)生成的差异化影响,文章基于多重分形去趋势互相关分析法和K均值聚类算法,对2016-2022年四川省15个重点城市城区和郊区不同站点NO_(2)-O_(3)互相关性的多尺度特征进行对比分析。结果表明,城区和郊区大气NO_(2)-O_(3)互相关性均具有多重分形性及长期持续性特征,且郊区站点多重分形强度显著高于城区。城区和郊区NO_(2)-O_(3)互相关性多重分形强度差异呈现逐年递增规律,且受季节影响较大,其中夏季城区和郊区差异最大,冬季最小,这些差异主要受O_(3)前体物排放特征和热岛效应的影响。研究结果有助于从新的角度理解城区郊区大气污染差异及形成机理,为城郊O_(3)精细化预测模型的完善提供动力参数。

对于功能梯度矩形板的自由振动问题,寻求既满足高阶偏微分控制方程又满足各种非Lévy型边界条件的振型函数十分困难,这使得利用传统方法难以解析求解该类问题.该文拓展了近年来发展的基于Hamilton体系的辛叠加方法,将其成功应用于功能梯度矩形板自由振动问题的解析求解.求解方案将原问题拆分成子问题,并引入物理中性面消除了由于横向材料不均匀产生的拉弯耦合效应,采用在传统Lagrange体系中无法使用的分离变量、辛本征展开等数学方法对子问题进行求解,最后通过叠加获得了原问题的解答.辛叠加方法的优点是不需要事先假定解的形式,克服了传统半逆解法的限制,能够获得更多复杂问题的解析解.将该方法的求解结果与数值解进行对比,证明了其正确性,并在此基础上进行了定量的参数分析,研究了不同边界条件、材料分布和长宽比对板固有频率的影响.
