Study on environmental control method in public and conservation of decorated stone chamber in tumulus

本研究的目的是为遗址石室的公共环境控制和遗址石室的保护提供基础技术。我们测量和调查了装饰石材外观和现场温度、湿度、冷凝水的年变化。通过对石室水分流动的分析，阐明了结露机理，并提出了防止结露的对策。其次，以光和石材的多重折射为材料背景，提出了润湿修饰石材外观变化模型，阐明了润湿修饰石材外观变化。最后，研究了含盐风化材料的吸附等温线，提出了考虑盐浓度及其结晶的吸附等温线预测模型。

The purpose of this study is to develop the fundamental techniques for environmental control method in public and conservation of decorated stone chamber in tumulus on site.We measured and investigated annual variation of the appearance of the decorated stone and temperature and humidity, condensation on site. We analyzed moisture flow in the stone chamber in order to clarify mechanism of condensation and proposed the counter measure to prevent the condensation. Next, we proposed a model to change of appearance of decorated stone by wetting considering multi refractions of light and stone as the material background and clarified the change of appearance by wetting. Finally, we investigated sorption isotherm of the material which includes salt caused salt weathering and propose a model to predict the sorption isotherm considering concentration of salt and its crystallization.
