Study on the Interaction Between Tangerine Peel and Beer by Absorption Spectrum

This paper presents a new method to study the interaction between tangerine peel and beer by absorption spectrum.The author explores the change laws and the differences of the absorbance on some wave band from the absorption spectrums of tangerine peel and the mixture of tangerine peel and beer. The results show that there is an obvious difference around 323 nm though the absorbance values of the two samples are almost similar in the most bands. The absorbance value of the mixture is obviously greater than that of tangerine peel at 276 nm in the spectrums, and there is a shift of the peak position in the absorption spectrum of the mixture, which shows the differences of the absorbance values and the peak positions of the two samples. Through comparing the characteristics of the two samples' absorption spectrums, a new method for researching new pharmacological action of tangerine peel is presented in this paper. The result indicates that the technology of spectrum analysis will play an important role in the research and development of Chinese herbal pharmacology and new pharmacology.

成像型任意反射面速度干涉仪研制

成像型任意反射面速度干涉仪是激光驱动冲击波研究的重要诊断设备，主要应用于惯性约束聚变脉冲整形实验、高压状态方程实验研究和材料特性研究。基于传统任意反射面速度干涉仪的特点，研制了一台基于神光Ⅲ原型装置的成像型任意反射面速度干涉仪，该系统可用于测量自由面速度及透明介质中的冲击波速度。给出了成像型任意反射面速度干涉仪的详细设计要点。对系统性能进行了分析及测试，结果表明时间分辨优于30ps，物方空间分辨约为10μm，测速范围为6～45km／s。
