土遗址加固保护中色差和透气性测试之评价研究

The Opinion of Chrominance and Ventilation Property Researches in the Protection of the Earthen sites

在土遗址加固保护中,对土遗址加固前后颜色变化(又称色差)和透气性的测试是衡量加固材料加固效果优劣的两个核心因素,同时也是建立土遗址加固评价体系中的两项关键技术指标,两者缺一不可。按照颜色科学领域中国际照明委员会CIELAB标准色度表色系统对色差的评价体系和利用国内外材料科学中对透气性的压差法中的重量测试法,对国内外现有的、常用的几种土遗址加固材料和正在研究中的加固材料进行了加固前后色差和透气性的系统测试,客观地对几种加固材料加固前后颜色变化大小和透气性的优劣作出了初步评价,也为建立土遗址加固的色差和透气性评价体系打下初步基础。

In the protection of the earthen sites, testings of colors change （also chrominance） and breathability in before and after treatment are two core factors that are judged reinforcement material consolidates effect superior or inferior and two key technologic indexes that are built evaluating system.At same time they are integral.Based on chrominance evaluating system of chromo CIELAB standard of the international lighting committee and simple pressure-testing of ventilation property in material science of home and abroad, the systemic testings of colors change and breathability in before and after treatment are carded on in several reinforcement materials of now available and common using home and abroad,and some materials of in studying. The results show that the basic evaluation has objectively been made changing size of chrominance and the Superior or inferior rank of ventilation property and the preliminary basis has been lay down for building evaluating system of chrominance and ventilation property of earth sites.
