近红外光谱技术在红砂岩文物风化研究中的应用

Application of Near-Infrared Spectrum Technology to Research of Weathering of Red Sandstone Relics

用现代近红外光谱分析技术研究红砂岩文物的风化机理,分别对六组红砂岩样品进行分析,结果表明近红外光谱技术能较好的分析红砂岩风化前后的物质组分,达到探究组分变化的目的,是一种快速有效的研究手段,且比其他研究技术更具测量样品用量少、速度快、无破坏、无污染的特点,这些优点表明近红外技术也能用于其他石质文物的研究,尤其对那些取样难、珍惜贵重、不能破坏的石质文物其作用更显得尤为重要。所以随着时代的进步近红外技术作为石质文物的研究手段将会越来越凸显其意义。

In the present paper,with near infrared spectroscopy technology,the weathering mechanism of red sandstone relics was studied.Six groups of red sandstone samples were analyzed using near infrared spectroscopy technology.The results show that the near-infrared spectroscopy technology can analyze the material composition of red sandstone before and after weathering,aiming to explore their components changed.So it is a quick and efficient means of research with characteristic of less measurement sample and speed and non-damage and being pollution-free compared with other research techniques.All the characteristic shows that it is also well for studying other stone cultural relics.Especially for those with sampling difficulty and treasure valuable,non-destruction of stone cultural relics is particularly important.So with time advancing,near infrared technology as a research means of stone relics,its meaning will be more prominent.
