石灰岩石刻文物表面硬度与生物风化研究——以南京明代石刻为例

Study of Limestone Statuary on Base of Rigidity——A Case Study on Stone Statuary of Ming Dynasty in Nanjing

从岩石表面硬度着手,分析了南京明代碳酸盐岩石刻文物溶蚀过程中表面微生物的作用.研究表明,同一岩性的岩石硬度在石刻文物风化程度上具有一定的指示作用,表面硬度与微生物作用之间存在相关关系,这种相关关系不是简单的线性相关,而是因材质、微生物类型、微生物作用方式的差异而有不同的表现形式,并初步分析了石刻表面微生物在石刻文物保护上的作用.

There are many cultures stone of Ming dynasty in Nanjing, all made of limestone. The paper divides the surface of culture stone into four types on base of overcast of diverse microorganism： nearly no overcast of microorganism, overcast of less microorganism, overcast of much microorganism, nearly all overcast of microorganism. And it uses schmit hammer to get their external rigidity and the connection between external rigidity and overcast extent of microorganism. It draws a qualitative conclusion of the connection of external microorganism： if culture stone is obvious of grain, then the external rigidity and the extent of overcast of microorganism is relational, others do not.
