针对滏阳河流域断流河道生态修复的问题,为了实现断流河道尽可能恢复有水时间并且恢复基本生态功能的目标,基于节水措施和调水工程现状,通过建立滏阳河流域SWAT(soil and water assessment tool)水文模型,在模型中设置不同补水水量、补水方式的生态补水情景,分析不同情景下断流河道断面的径流量变化和恢复有水天数,并结合生态流量评价标准评价不同情景的河流生态恢复效果。结果表明:滏阳河流域邯郸断面在节水情景和调水情景中恢复河流生态效果较好,在通过上游节水措施和补充年调水1.00×10^(8)m^(3)/a的情景下,可以达到5—10月恢复有水184 d、恢复径流量3486.7×10^(4)m^(3)/a的目标;年内恢复径流峰值在8月中旬,并且河道年均径流量可以恢复到“好”等级的生态流量标准。滏阳河下游邢台断面在节水情景和调水情景下恢复径流量较少,河道有水天数不达标,需要在上游节水条件下补充外来调水水量1.50×10^(8)m^(3)/a来达到恢复年有水天数304 d、恢复径流量1906.5×10^(4)m^(3)/a的目标,年内恢复径流峰值分别在3月中旬和8月中旬;并且在达到恢复有水目标的情景下邢台断面仅达到“一般”等级的生态流量标准,需要考虑增加调水水量进行分时段单点位补水的补水方案。

随着市场竞争日趋激烈,创新主体的组织形态发生了重要变化,开放式创新生态系统范式顺应而生.由此,本研究基于将生态系统概化为隶属关系的观点,探讨生态网络结构对开放式创新生态系统价值共创的影响机理及其情景因素,并通过收集生物医药行业145家上市公司2010年—2018年构成的1305个观测值的平衡面板数据,采用社会网络分析和多元回归等方法对其进行实证检验.研究结果表明:1)生态网络结构的两个维度(生态网络密度和生态网络结构洞)均对价值共创具有显著的正向影响;2)稳定性在生态网络结构的两个维度与价值共创关系之间发挥中介作用;3)生态位宽度和生态位重叠度调节生态网络结构的两个维度与价值共创的关系,且调节效应存在差异;4)生态网络惯例在“生态网络结构洞-稳定性-价值共创”中介路径中发挥正向调节作用;但由于过强的网络规范共识会导致合作伙伴之间的路径依赖,其调节“生态网络密度-稳定性-价值共创”中介路径中的边际效应减弱.本研究不仅完善了开放式创新生态系统价值共创的理论框架,也为企业打造更加持续稳定的开放式创新生态系统提供了理论借鉴.

基于高阶剪切变形理论提出了一种功能梯度板自由振动分析的简化模型,该简化模型最显著的特点是适用于功能梯度板的振动分析,且不需要剪切修正。相比于其他具有更多未知变量的剪切变形理论,本文提出的简化模型只包含一个控制方程,极大地减少了计算量。基于该简化模型研究了功能梯度矩形板在简支边界条件下的自由振动,并与其他已有文献进行了比较。结果表明,本文提出的简化模型在分析功能梯度板的自由振动行为时简单且精确。此外,文中还通过多个数值算例分析讨论了不同的梯度指数、长宽比和边厚比对功能梯度板自由振动行为的影响。

近年来,商丘市臭氧(O_(3))污染日益凸显,尤其是夏秋季,严重影响了当地环境空气质量.基于商丘市环境监测站2022年6月和9月(分别代表夏季和秋季)O_(3)污染天的监测数据,运用基于观测的模型(OBM)研究了该市O_(3)污染成因和光化学反应特征,并开展了前体物减排策略研究.观测结果表明,商丘市夏季ρ(O_(3))和O_(3)日最大8 h滑动浓度[ρ(MDA8-O_(3))]均值分别为149.7μg·m^(-3)和195.4μg·m^(-3),而秋季ρ(O_(3))和ρ(MDA8-O_(3))均值分别为119.8μg·m^(-3)和173.9μg·m^(-3),夏季O_(3)浓度显著高于秋季.臭氧敏感性研究表明,商丘市夏秋季O_(3)生成均为挥发性有机物(VOCs)控制区,其中,含氧类挥发性有机物(OVOCs)、芳香烃和烯烃物种对臭氧生成潜势(OFP)和·OH反应性(L·OH)贡献最大,需加强管控.OBM模拟结果表明,夏秋季O_(3)生成速率最大值分别为23.0×10^(-9) h^(-1)和13.6×10^(-9) h^(-1),净生成速率最大值分别为17.4×10^(-9)h^(-1)和10.4×10^(-9)h^(-1),夏季O_(3)的生成速率最大值和净生成速率最大值均为秋季的1.68倍,说明夏季光化学反应明显强于秋季;与夏季相比,秋季O_(3)生成受其他区域输入影响较大,最大输入量达14.2×10^(-9) h^(-1).商丘市夏秋季O_(3)污染防治应以控制VOCs为主,秋季VOCs/氮氧化物(NO_(x))的减排比例应大于夏季,可分别采取夏季3∶1和秋季4∶1的减排比例进行管控.
