[Objective] The research aimed to study the Juglans regia and Arachis hypogaea by Fourier transform infrared spectroscopy (FTIR).[Method] The infrared spectra of Arachis hypogaea and Juglans regia from six different producing areas were analyzed.[Result] The results showed that the spectral shape and position of the peaks were very similar for the Juglans regia from different areas and between the Juglans regia and the Arachis hypogaea.The differences were observed among the absorbance ratios of several peaks.For the Juglans regia and Arachis hypogaea,the absorbance ratio A1746/A1653 was greater than 1,while A1099/A1653 was slightly larger than 1 for the Juglans regia and less than 1 for the Arachis hypogaea.By the differences of absorbance ratios of A1746/A1653 and A1099/A1653,Juglans regia from six different areas might be discriminated.[Conclusion] The FTIR might be a rapid,convenient simple and non-destructive method in determination of the origin of agricultural products.

摘 要: 由于国家考试招生制度改革的深入推进,农业院校自主招生工作面临新的形势。本文运用SWOT分析法,通过对比农业院校及其他试点院校自主招生,明确新形势下农业院校自主招生独特的优势S、劣势W、机遇O、威胁T,在此基础上提出对策建议,以进一步完善和发展农业院校自主招生制度,为选拔和培养我国优秀农业人才助力。  关键词: 农业院校 自主招生 SWOT分析  作为我国高校考试招生制度的重要组成部分,自
高考英语全国卷中完形填空占了相当的分值,各省市自命题卷中也大多包含完形填空这一题型,因为完形填空能比较准确地考查考生阅读理解、词汇及语法知识运用等综合能力。它要求考生在选项中选取一个最佳答案,而非唯一正确答案,这就增加了难度,因为往往并不是唯一选项意思契合上下文,也并不一定唯一选项语法恰当。在这种情况下,考生唯有对文章的理解达到一定准确程度,对英语语言有一定驾驭能力,才能够甄选出一个最符合上下文意
摘 要: 近年来在高考理综的考试中,生物科目的选择题变得越来越少,只有6道题,但是这6道题在知识角度上将整个高中生物教材的所有章节进行了覆盖,在难度上也进行了适当区分。高考理综生物选择题的分值比较大,在高考过程中解答好生物选择题,对那些由于非知识性因素造成的失分现象尽量避免,这是高中生物教师和学生都要注意的问题。本文结合高考理综生物选择题的审题和解答,给解题策略方面提出一些意见,希望可以对学生对理
