2023年是党的二十大召开后的第一年,也是建设中国式现代化的开局之年。党的二十大报告首次提出“加快建设农业强国”①,2023年中央“一号文件”将建设供给保障强、科技装备强、经营体系强、产业韧性强、竞争能力强的农业强国摆上建设社会主义现代化强国的重要位置②,这是党中央着眼全面建成社会主义现代化强国作出的战略部署。当前,国内农业在国际竞争力、农业生产效率、科技创新能力、资源利用率、生产要素流动等方面依旧存在不足,农业强国是社会主义现代化强国的根基,强国必先强农,农强方能国强。基于建设社会主义现代化强国的需要,探讨如何加强建设农业强国、借鉴吸取国外现代化农业强国经验,对建设中国式现代化具有重要意义。

基于零部件的基本库存水平补货策略,在多周期订单产品需求不确定情况下构建两阶段随机优化模型:第一阶段在需求未知情况下,规划不同零部件基本库存水平决策变量,实现系统收益最大化;第二阶段针对订单交货期约束创新性设计订单指派决策变量,考虑在不确定需求收益和订单延期惩罚情况下,最大化订单期望收益.通过采样获取不同需求场景,并将不确定需求转成期望需求,针对该期望需求下的单阶段确定性模型求解,并与随机模型结果进行对比.数值实验表明,随机模型的优化结果远差于确定性模型,即未知信息具有一定的价值;同时通过对模型中参数的灵敏度分析,得到了实际中提升系统收益的策略.

以EDTA为螯合剂的亚铁络合脱硝液能够快速吸收NO,但其面临着还原再生效率低下的问题。针对吸收产物Fe(Ⅱ)EDTA-NO(F-NO)和Fe(Ⅲ)EDTA的阴极催化电化学还原制备了一种以泡沫镍为基底的Fe、Cu双金属复合电极,通过SEM、XPS、XRD等材料表征分析验证了此电极制备方法的可行性。电化学催化活性测试表明,还原FNO时设定阴极电位为-0.5 V(***),pH为3~4之间,可以实现72.6%的F-NO还原率和83.19%的NH_(4)^(+)选择性;还原Fe3+时选定阴极电位为-1.2 V(***),pH=2~3,此时还原产生Fe^(2+)的法拉第效率最高可以达到76.14%。此外,还考察了此电极连续工作10 h的还原效果,结果证明了其在实际运行中具有良好的稳定性。
