中文摘要：

大足石刻千手观音凝结水的定量研究中,由于雕刻砂岩风化表层的吸附作用,使肉眼观测圈定凝结水分布面积十分困难。为了解决这一问题,根据千手观音凝结水区域红外辐射特征与周围环境存在着明显差异,利用红外热成像仪对千手观音造像区的凝结水进行了检测。结果表明,千手观音造像区凝结水十分严重,即使在比较干燥的冬季,也有凝结水分布,面积约为9.26%,春季开始大面积产生凝结水,分布面积达51.05%,千手观音造像区不同部位的凝结水分布差异性明显,左下角凝结水最为丰富,从下往上凝结水的分布面积逐渐减少。研究表明,利用红外热成像技术可以精确地检测凝结水的面积。

英文摘要：

In the quantitative study of the condensation water of Avalokitesvara statue in Dazu Rock Carvings,it is difficult to see and delineate the distribution area of the condensation water due to the adsorption of mantle rock regolith on sandstone sculpture.Therefore,according to the significant differences of infrared radiation characteristics between the condensate area and the surrounding area,the authors used infrared thermal imaging devices to detect the condensate zone of Avalokitesvara statue.The results show that the condensation water of Avalokitesvara statues is very serious.Even in the relatively dry winter and spring,the condensate zone takes up about 9.26% and 51.05% of the whole area.Meanwhile,the regional difference in the distribution of the condensation water is obvious,that is,condensation water in the lower left corner of the Avalokitesvara statue is the most abundant,and it gradually decreases from the bottom of the distribution area upward.Studies show that the infrared thermal imaging technology can accurately detect the area of the condensation water.
