    为考察火花放电等离子体射流控制机翼气动力矩的效果,在NACA0021平直机翼模型上安装火花放电等离子体射流发生器,通过改变射流发生器安装位置、射流角度及加载电参数,研究其控制机翼模型气动力矩的性能及机理。在NACA0021机翼模型近前缘处,布置2个火花放电等离子体射流发生器,采用气动力测量技术,在来流风速为20 m/s时测得,攻角-4°~10°时,滚转力矩系数最大减小了0.0024,攻角为12°~16°时,滚转力矩系数最大增加了0.0021;偏航力矩系数最大减小了0.00097。实验研究结果表明:等离子体射流可改变机翼模型横航向气动力矩,并可通过改变射流角度和加载电压频率调节等离子体射流控制横向气动力矩的效果。To investigate the control effect of Spark Discharge Plasma Jets(SPJs) on the aerodynamic moments of a wing, SPJ generators were used for active flow control experimental study on an NACA0021 straight wing model. The location of SPJ generators along the chord of the airfoil, the jet flow direction relative to the chord, and the driving voltage parameters were changed to research the control effect and mechanism of SPJ generators on the aerodynamic moments of a wing model. The aerodynamic moments were measured with a six-component balance at a wind speed of 20 m/s. Two SPJ generators, arranged near the leading edge, reduced the rolling moment coefficient by a maximum of 0.0024 for angles of attack-4°~10°, but increased the rolling moment coefficient by a maximum of 0.0021 for angles of attack 12°~16°. The yaw moment coefficient was reduced by a maximum of 0.00097. The results show that aerodynamic moments control of wings can be realized using SPJs. The control effect of SPJs on the aerodynamic moments is changeable by adjusting the driving voltage frequency and the jet flow direction relative to the chord.航空科学基金项目(20141368007);; 福建省自然科学基金项目(2010J01014

    为研究海南珊瑚礁区重金属的污染现状,选择鱼类为污染指示物,测定珊瑚礁区的5种鱼体中Cr、Mn、Cu、zn、AS、Pb和Hg 7种重金属的含量,并采用单因子污染指数法(PI)对重金属的污染状况进行了风险评价。研究结果显示,不同鱼类对同种重金属元素的富集能力存在较大差异,同种鱼对不同重金属元素的富集能力也存在差异。珊瑚礁区鱼类重金属的污染程度由强到弱的顺序为:Cr>AS>Mn>Hg>zn>Cu>Pb;鱼类的鳃和内脏器官比肌肉更容易蓄积重金属。珊瑚礁区生物富集作用最明显的为Cr和AS。PI结果表明海南珊瑚礁区鱼体重金属Cr的污染严重,AS中度污染,其他重金属基本无污染或轻度污染。To study the pollution status quo of heavy metals in coral reef ecosystem in Hainan Island,concentrations of heavy metals including Cr,Mn,Cu,Zn,As,Pb,and Hg in wild fish were determined.Single factor pollution index(Pi) was employed to evaluate the heavy metal pollution level.The results showed that enriched degree of the heavy metals in fish can be ranked from high to low as Cr>As>Mn>Hg>Zn>Cu>Pb;heavy metals prefer to be accumulated in gill and viscera.Obvious bioaccumulation of Cr and As in fish of coral reef ecosystem was observed.Pi indicated that coral reef ecosystem in Hainan Island has been heavily polluted by Cr and moderately polluted by As.Other metals have shown no pollution or slight pollution.中国博士后科学基金(2012M510201); 中国科学院百人计划资助项目(2060299); 中国科学院南海海洋研究所知识创新工程领域前沿项目(50601-31); 王宽诚教育基金会对本工作的资

    为更 多地保留活性成分,提高油茶籽油品质,研究了油茶鲜果6种不同预处理方式(剥壳-摊晒、直接摊晒、堆沤-摊晒、剥壳-烘干、直接烘干、堆沤-烘干)对油茶籽主要成分以及低温压榨油茶籽油中3种理化指标(酸值、过氧化值、多环芳烃)和4种微量活性成分(维生素E、维生素K1、角鲨烯、多酚)的影响。结果表明:油茶鲜果预处理方式对油茶籽主要成分(脂肪、蛋白质、淀粉)影响不大;6种不同预处理方式对低温压榨油茶籽油的理化指标和微量活性成分均有一定的影响,其中剥壳-烘干处理油茶鲜果在油茶籽油的酸值、多环芳烃、维生素E、角鲨烯指标上较其他预处理方式存在一定优势。综上,采用剥壳-烘干对油茶鲜果进行预处理,可在一定程度上提高油茶籽油品质。 In order to retain more active components and improve the quality of oil-tea camellia seed oil, the effects of six different pretreatment methods of fresh Camellia oleifera fruit(shelling-spreading, direct spreading, retting-spreading, shelling-drying, direct drying, and retting-drying) on the main components of oil-tea camellia seed, as well as three physicochemical indexes (acid value, peroxide value, and polycyclic aromatic hydrocarbons) and four trace active components (vitamin E, vitamin K1, squalene, and polyphenols) of low-temperature pressed oil-tea camellia seed oil were studied. The results showed that the different pretreatment methods had little effects on the main components (fat, protein, starch) of oil-tea camellia seed, and had certain effects on the physicochemical indexes and trace active components of low-temperature pressed oil-tea camellia seed oil. The shelling-drying method had certain advantages over other pretreatment methods in acid value, polycyclic aromatic hydrocarbons, vitamin E, and squalene of oil-tea camellia seed oil. In conclusion, the shelling-drying pretreatment of fresh Camellia oleifera fruit can improve the quality of oil-tea camellia seed oil to a certain extent
