21世纪以来,艺术参与乡村实践逐渐形成一股风潮,一定程度上影响着乡村发展转型与重构。本文基于乡村三重空间模型,结合以行动实践捕捉权力形式的框架,通过综合比较艺术参与乡村的不同实践模式,分析艺术参与下的乡村空间重构表现,并进一步探讨其影响机制,以期为艺术助推乡村振兴提供审慎参考。首先,乡村空间重构表现如下:乡村地区的突变往往作为显著特征,包含物质空间的结构性改变;乡村表征由话语权力主体进行再定义,以艺术方、当地政府和社会资本为主导力量;乡村生活则因此充满混杂与不确定性,与村民的日常生活、传统观念产生碰撞;此外,其每一部分都与其他部分相互作用。再者,乡村空间重构受到内源性因素和外源性因素的共同影响,二者持续相互作用,在一定时间的积累后,促进民众参与和集体认同,从而推动乡村在新阶段的转型与发展。

为有效计及风电出力随机性对电网运行状态的影响,在风电并网系统中提出一种基于高斯函数-最大熵原理的改进半不变量概率潮流计算方法。首先,以高斯函数为风速分布信息的载体,在此基础上采用改进反射核密度估计,建立计及风速有界性的风电出力概率模型,以便精确地求取描述风电出力随机性的各阶矩、半不变量等数字特征。然后,基于节点电压、支路功率等状态变量的数字特征,采用高斯函数改进最大熵模型进行状态变量的分布展开,由高斯函数的数量和性质来计及输入侧风速分布形状对输出侧状态变量分布的影响。同时将所提改进最大熵模型的约束由积分形式转为代数形式,提升计算效率。最后,以IEEE30节点系统对所提方法进行测试,结果证明了所提方法的有效性、准确性。

依托冷库制冷系统性能实验台,基于不同的风冷冷凝器风机频率,对冷库降温过程中的制冷剂流量进行监测,定量分析压缩机输气量变化规律。结果表明:冬季工况下,冷库从-2~-18℃的降温过程中,压缩机输气量先较快升至某一最大值,然后再缓慢下降并趋于稳定;库温高于极值点时,冷凝器风机频率变化对输气量影响较大,提高风机频率可使输气量增大约10%;低于极值点时,则影响较小。应用SPSS软件,建立压缩机输气量与蒸发压力、冷凝压力的二次多项式回归模型,56组测试数据与预测值的相对误差均<±3%。

NaCl含量对水产制品的品质,尤其是对腌制品的持水性、质构特性以及鱼糜制品的凝胶性能至关重要。然而,传统水产制品中NaCl含量普遍过高,无法满足消费者对低盐健康方便食品的需求。直接减少NaCl含量会降低水产制品的贮藏稳定性、食用性及加工性能,因此在保证水产制品品质的同时减少钠盐含量是水产制品加工业面临的重要课题。实现有效控制低盐水产制品品质的前提与基础是明确NaCl对水产制品品质的影响机理。本文在概述NaCl在水产制品加工贮藏中的作用的基础上,从NaCl替代物、新型减盐加工技术和钠离子释放/感知提升技术3个方面综述国内外在水产制品减盐技术方面的最新研究进展,并提出水产制品减盐加工过程中存在的问题,对实现低盐水产制品高质化加工具有重要理论和应用价值。

研究了偏高岭土对蒸养(60℃蒸养12 h)钢渣水泥基材料早期水化和力学性能的影响。结果表明:复掺偏高岭土后,蒸养钢渣偏高岭土复合水泥胶砂的力学性能显著提高,最佳掺量下能够与纯水泥胶砂的力学性能持平。偏高岭土加速了蒸养钢渣水泥的早期水化,并加速了硫酸盐消耗,促进AFm相的形成。蒸养钢渣-偏高岭土复合水泥体系中C-S-H和C-A-S-H凝胶量增多,生成碳铝酸盐相固定活性Al_(2)O_(3),有利于稳定钙矾石相。同时,偏高岭土显著改善了蒸养钢渣水泥体系的孔隙分布,使基体更加密实。
