针对高压脉冲电源反电晕放电进行实验研究。采用正极性固态Marx脉冲发生器作为放电电源,以中间添加蜂窝介质的针板作为放电电极,设置正极性矩形高压脉冲输出电压为0~20 kV可调,工作频率为0~1000 Hz可调,脉冲宽度为10~500μs可调,进行反电晕放电实验,并根据电源和电极参数对影响放电电流大小的因素进行分析。进一步,在相同放电电极参数条件下,将高压脉冲反电晕与直流反电晕进行了对比研究。研究结果表明:介质厚度、针板间距、脉冲宽度和放电频率均对反电晕放电电流有一定影响;在脉冲放电频率为100~1000 Hz时,发生反电晕的相同电压下,脉冲反电晕放电电流大于直流反电晕放电电流,证明高压脉冲激发反电晕放电效果更好。

酸性电解水(acidic electrolyzed water,AEW)处理属于新型的果蔬采后保鲜方式。该实验探讨AEW处理对龙眼果实采后贮藏期间活性氧(reactive oxygen species,ROS)代谢的影响。结果表明:相比对照组,pH 2.5、有效氯质量浓度80 mg/L、氧化还原电位1512 mV的AEW浸泡果实10 min能显著提高贮藏期间龙眼果肉抗氧化酶(抗坏血酸过氧化物酶、过氧化氢酶和超氧化物歧化酶)活性,保持较高水平的非酶抗氧化物质(如还原型谷胱甘肽和还原型抗坏血酸)含量,及较高的1,1-二苯基-2-三硝基苯肼自由基清除能力和还原力。此外,AEW处理可显著降低果肉超氧阴离子产生速率和过氧化氢含量(P<0.05),从而有效抑制丙二醛含量的上升。据此推测,AEW处理增强龙眼果实的耐贮性可能与其提高采后贮藏期果肉的ROS清除能力紧密相关。

以介孔硅MCM-41为载体、无水乙醇为溶剂、氯化铝为促进剂,采用浸渍法制备了Pt-Al/MCM-41催化剂。利用XRD、XPS、TEM、FTIR、N_2吸附-脱附、NH3-TPD对催化剂进行了表征,重点讨论了不同Pt-Al负载顺序对催化剂结构和性能的影响,并将其应用于硅氢加成反应。结果表明,Pt和Al的负载顺序不同会影响催化剂的有序度、Pt颗粒的分散程度和酸性,其中,Pt-Al/MCM-41催化剂的有序度和Pt颗粒的分散程度相对最好,酸性相对较强。在七甲基三硅氧烷与烯丙醇聚氧乙烯醚的硅氢加成反应中,不同催化剂对七甲基三硅氧烷的转化率影响顺序为Pt-Al/MCM-41>Pt+Al/MCM-41>Al-Pt/MCM-41>Pt/MCM-41。
