[Objective]The aim was to establish the fingerprints of Alpinia oxyphylla Miq.by HPLC.[Method]The HPLC was used and the chromatographic conditions were as follows:column of ODS Hypersil VP-ODS(150 L×4.6 mm),mobile phases of water-acetonitrile(V:V=70:30),sampling volume of 20 μl and detection wavelength of 220 nm.[Result]The fingerprints of Alpinia oxyphylla Miq.obtained from different areas of Hainan Province were similar,while different from that obtained from Guangdong Province and Guangxi Province.The fingerprints of Alpinia oxyphylla Miq.obtained from Guangdong Province and Guangxi Province were similar as that obtained from the other areas.[Conclusion]Ten kinds of fingerprints were obtained by this rapid,convenient and reliable method,which would be a new rapid identification method for Alpinia oxyphylla Miq..

摘要:语音是语言最基本的要素之一,也是学好一门语言的关键。小学生模仿力强、记忆力好、可塑性强,所以教师可以从语音入手,抓好英语基础教学。  关键词:小学英语 语音 重要性 教学方法  一、字母语音两不误  1.辅音字母须渗透  在教学26个字母时,教师不要忘记语音的渗透。如在教学21个辅音字母时,教师可以渗透和这些字母相对应的一些辅音发音,如b b /b/ /b/ /b/,d d /d/ /d/
