文章研究了风味鱼仔加工过程中挥发性风味成分的变化情况.采用顶空固相微萃取-气质联用(HS-SPME-GC-MS)技术分别检测鲜海鱼浸泡、清洗、油炸、卤制、拌料、杀菌前后7个不同工序的风味成分变化.结果 表明,卤制和拌料阶段风味变化明显,是风味产生的主要加工阶段,酯类、烯类以及醇类大幅度增加.7个工序挥发性风味成分种类数分别为33,32,18,19,30,31,28种,成品(S)中芳樟醇、()4萜品醇、桧烯、月桂烯、右旋萜二烯、乙酸芳樟酯含量较高,相对含量分别为13.46%、2.88%、3.21%、2.08%、7.08%、34.29%.此外,结合阈值大小确定了与腥味相关的11种风味物质:壬醛、己醛、庚醛、(Z)-4-庚烯醛、2,4-癸二烯醛、1-戊烯-3-醇、2-正戊基呋喃、2-乙基呋喃、2,4-癸二烯醛、松油烯和1-辛烯-3-醇.上述结果为风味鱼仔加工中气味控制和鱼制品脱腥提供了科学依据.

This article provides an assessment of the changes in marine climate drivers (hazards), associated impacts, risks, and adaptation to the coastal China zones and seas since the mid 20th century. The results show that:①Marine climate drivers, such as ocean
探究气候的干湿格局及其演化趋势对旱涝灾害监测防御具有重要意义,围绕北方内蒙古生态功能区重要定位,依据1970-2020年45个气象监测站点月尺度降水资料,采用标准化降水指数(SPI),运用线性趋势、突变检验及Morlet小波分析等方法,探究内蒙古地区多时间尺度下气候的干湿特征及周期演化规律.结果 表明:1970-2020年,内蒙古地区干旱强度以轻中旱为主,局域性和全域性干旱频发,夏季干旱趋势显著,且明显高于年际干旱化水平;不同生态功能区干湿空间格局呈现东北部林区和西部荒漠区旱情缓减、中部草原区旱情加重、且
This paper studies the environmental effects of technical change using a spatial model with panel data from 284 prefecture-cities over 2004–2015 in China. We find that the effects of technical change vary across different dimensions of technical change an

跃移是推移质泥沙颗粒运动的主要形式之一,跃移颗粒的运动特性是影响推移质输沙率的重要参数,但目前对跃移泥沙颗粒的起跳时间研究相对较少.本文利用高速摄影技术,对不同粒径泥沙起跳过程进行了系列的试验研究,后期采用RGB颜色映射函数获得灰度图,通过逐帧批处理获取颗粒的运动轨迹,直接得到了泥沙颗粒的起跳时间大小.试验结果表明,在本文试验的水沙条件下,泥沙颗粒的起跳时间呈现偏态分布,随着水流作用流速与特征沉速之比从0.3增大至0.7,起跳时间的变化趋势不显著.在此基础上,利用Gilbert和岗恰洛夫两家输沙率实测资料
