求助翻译摘要

番茄中含有番茄红素和β-胡萝卜素两种重要的营养成分。两种成分的主要拉曼光谱基团相同，利用基频很难在体将两种成分区分开。我们利用共振拉曼光谱技术，通过测量二次谐波，用软件获得每种成分光谱的积分强度而得到番茄红素和β-胡萝卜素的含量。本文为在体检测同种基团成分含量提供一种方法。 [search]翻译[/search] [ Last edited by ouyangshunli on 2008-8-4 at 14:45 ] |

the main raman spectrum group of lycopene and β-carotene abundant in tomato is identical and difficult to be distinguished through fundamental frequency. In this article, upon resonance raman spectrum technology, the content of lycopene and β-carotene has been determined through spectrum integral intensity of each compound obtained by measuring second harmonic. the present article proposes a method to determine the composition content of compound with identical group.

| Tomato contains lycopene and β-carotene two important nutrients.Two ingredient main Laman spectrum genes are same, it is very difficult to separate the two components using the base frequency in the body .We use resonance Laman spectrum , the measurement of second harmonic, obtain the integral intensity of each ingredient spectrum with the software , obtain the lycopene and β-carotene content.This paper provided a method of detection of the same group content in the body |
