长期以来,美术界一直关注四川美术学院的油画创作现象。过去的研究多集中在20世纪80年代初的伤痕美术、乡土绘画等,对90年代以来四川美院油画创作的新变化缺乏完整深入的了解和探究。本文梳理了四川美术学院油画近30年的创作历程,对这段时期绘画风格演变和艺术观念转向的历史动因和内在逻辑展开全面分析,试图厘清四川美院当代油画的发展脉络,并阐释其艺术史意义。此外,本文还结合四川美院油画系教学实践的几次重要转型,为相关分析和阐释补充一种“内在”视角。

为提高在碱性环境中的过渡金属的电催化性能并降低使用成本,合成一种新型尖晶石异质结构的催化剂,并研究R-CFO在1.0 mol/L KOH溶液中的电催化活性及其催化机理。以硝酸钴、硝酸铁、三氯化钌为原料,制备出Ru O_(2)@Co Fe_(2)O_(4)新型材料。通过XRD、TEM、XPS、电化学实验和理论计算等方法,研究R-CFO在1.0 mol/L KOH溶液中的催化活性及其催化机理。电催化实验表明,合成的新型催化剂R-CFO在碱性环境下的电流密度为10 m A/cm^(2)时的过电位和Tafel斜率仅仅需要215 m V和50.93 mV/dec,电流-时间变化曲线中表现出催化剂较为稳定,合成的R-CFO电催化剂表现出优异的催化性能。因此,本文提出了一种很有前途的方法,对电催化具有潜在应用价值。

针对传统A^(*)算法八邻域搜索路径节点多导致搜索及规划路径速度慢的问题,提出1种融合改进斜四邻域A^(*)与三次B样条曲线的路径规划算法。在传统八邻域搜索启发下,删除原本上下左右4个方向上的搜索路径,保留右上、右下、左上及左下4个方向的搜索路径,使算法在搜索时速度更快,搜索路径节点数更少;引入三次B样条曲线,优化路径上的尖锐拐点,使路径更平滑。采用提出的算法与其他2种算法在3种不同分辨率及不同障碍率的地图上进行实验验证。结果表明:相比于传统A^(*)算法,改进斜四邻域A^(*)算法的搜索时间缩短83.4%,路径节点数减少89.7%;引入的三次B样条曲线使斜四邻域A^(*)算法规划出的路径更平滑,提出的算法可极大提高路径搜索及规划的有效性。

维生素B_(3)及其代谢物是婴儿身体生长和细胞代谢所必需的物质,而不同物种乳中维生素B_(3)的组成尚未明确。本文章采用液质联用法分析了母乳、黑白花牛乳、羊乳、牦牛乳和娟姗牛乳中4种不同形式维生素B_(3)及其代谢物含量。结果表明,5种原料乳中4种维生素B_(3)及代谢物烟酰胺腺嘌呤二核苷酸(NAD^(+))均有检出,但其含量有显著差异。母乳主要由烟酰胺单核苷酸(NMN)及烟酰胺(NAM)构成,其含量分别为1 779.04 ng/mL和1 613.58 ng/mL;其余4种原料乳主要由NAM及烟酰胺核苷(NR)构成,其中羊乳NAM含量为2 508.39 ng/mL,占比高达96.07%;黑白花牛乳NR457.89 ng/mL,占45.88%。此外,母乳中NAD^(+)的含量显著高于其他原料乳。为婴幼儿生长发育的精准营养调控及配方奶粉中维生素B_(3)添加量及添加形式的研究提供理论依据。
