水稻(Oryza sativa L.)是全球种植最广泛的粮食作物之一,在全球粮食安全中扮演着至关重要的角色。陈化是稻谷储藏过程中发生的一种自然现象,其机制至今未阐明。在储藏过程中,稻米的感官、蒸煮和糊化特性等理化性质以及淀粉结构与功能都会发生不同程度的变化。这些变化大多与储藏时间和温度有关,并且对稻米品质的影响是不可逆的。虽然已有许多研究关注稻米陈化过程中相关的理化性质变化,但对稻米储藏后淀粉精细结构的研究还不多。本文综述了稻米人工陈化类型、陈化方法以及陈化对稻米理化性质和淀粉精细结构变化影响的最新研究进展,为进一步阐明稻米陈化机制提供了理论依据。

以镍基高温合金GH4169超薄带材为研究对象,构建了考虑晶粒尺寸和晶界的本构关系,与通过单拉试验获得的应力应变曲线对比发现,该模型可以较好地预测不同厚度和晶粒尺寸的GH4169超薄带材的流动行为。为分析材料参数和工艺参数对带材U形弯曲回弹的影响,开展了U形弯曲试验。结果表明,回弹角随晶粒尺寸、材料厚度和压边力的增大而减小,而冲压速度对回弹无显著影响。为对比晶粒尺寸、带材厚度、压边力和冲压速度对U形弯曲回弹影响程度的关系,设计了4因素3水平的正交试验,使用所建立的本构模型进行了U形弯曲回弹数值仿真。结果表明,带材厚度对回弹的影响程度最大,其次是压边力和晶粒尺寸,而冲压速度对回弹的影响最小。晶粒尺寸对三个回弹参数的影响均显著,而带材厚度对于回弹角θ2和回弹半径的影响较显著,但对回弹角θ_(1)无明显影响,压边力对于回弹角θ_(1)的影响最为明显,回弹半径ρ次之,对于回弹角θ2的影响最不明显。
