贵州不同油茶物种及产地对油茶籽油品质的影响Influence of different species and origins on quality of oil-tea camellia seed oil in Guizhou

open access: yesZhongguo youzhi, 2022
为探究贵州不同油茶的生产适应性,分析贵州本土油茶物种与普通油茶的差异性,研究不同产地对油茶籽油品质的影响,对贵州2个主要油茶物种(威宁短柱油茶、西南红山茶)和3个主要产地(贵阳、平塘、册亨)的普通油茶籽仁含油率及其制取油脂的理化特性、脂肪酸组成与活性物质含量进行检测,应用聚类分析和主成分分析进行综合评价。结果表明,威宁短柱油茶和西南红山茶籽仁的含油率较高,分别达到了57.76%和56.08%,与普通油茶差异显著(p<0.05)。各物种及产地的油茶籽油不饱和脂肪酸相对含量差异不显著(p>0.05 ...

考虑用电形态相似度的多用户共享储能投资决策 [PDF]

open access: yes全球能源互联网, 2021
在大规模可再生能源渗透的背景下,利用储能装置促进可再生能源消纳并降低用户成本逐渐成为发展趋势。以电能用户为研究对象,深入挖掘并构建用户侧储能综合效益模型;建立多用户共享储能的容量配置投资决策模型,基于用电形态相似度,提出了以高、低2种相似度为标准的共享储能模式下用户筛选方式,以提高共享储能的经济效益。算例分析对比了高、低2种用电形态相似度下用户集体共享储能的经济性,给出了共享储能容量配置的投资决策结果,以高用电形态相似度作为用户筛选标准可以获得更大的共享储能经济效益,并且经济效益与用户数量呈现正相关。

产地、物种及加工工艺对油茶籽油中的微量元素 及重金属含量的影响Effects of origins,species and processing technology on contents of trace elements and heavy metals in oil-tea camellia seed oil

open access: yesZhongguo youzhi, 2022
以贵州不同产地及物种的油茶籽为原料,分别采用烘制和炒制对其进行预处理后压榨制油,并对油茶饼进行二次压榨制油,对不同预处理及不同压榨阶段油茶籽油的微量元素及重金属含量进行分析。结果表明:不同产地和物种的油茶籽油的微量元素及重金属含量存在不同程度的差异,形成不同品质特征的油茶籽油;与烘制预处理相比,炒制可以显著提升油茶籽油中锰、铁、铜含量(P<0.05),但同时增加油茶籽油中的重金属含量;不同压榨阶段油茶籽油的微量元素含量具有显著差异(P<0.05),二次压榨可使油茶籽油中的锰和铁含量显著增加(P<0.05)

Superior CO2 Conversion Performance by Er‐Doped BiOCl Nanosheets Through Synergistic Photocatalytic Memory Effect and Er‐Doping

open access: yesCarbon Energy, EarlyView.
Er‐doping and the photocatalytic memory effect through visible‐light irradiation synergistically reconstruct internal electronic states of ultrathin Er‐doped BiOCl nanosheets and generate stable oxygen vacancies. Light absorption, charge carrier separation, and CO2 adsorption capability are subsequently enhanced, leading to a significant increase in ...
