摘要/Abstract

摘要： 酸雨是侵蚀我国大部分地区石质文物的主要威胁之一．近几十年来，室外的许多碳酸岩石刻和石雕都因此受到了不同程度的破坏．但是，在许多石质古迹上偶尔可以看到某些部位的石刻文字至今保持完好，仔细观察发现其表面有一层天然形成的保护膜．本工作对这种膜的样品分别进行了ＦＴＩＲ、ＰＬＭ、ＥＤＡＸ、ＳＥＭ和ＴＥＭ分析，结果表明这是一种以草酸钙为主要成分的致密的生物无机膜．本文简要讨论了这种膜的分析结果和形成机理．

Abstract: A crude conservation film was found that formed naturally on the surface of some historic stone buildings and monuments. It was so well preserved
that the stone inscriptions under the film were not damaged though they were made one more thousand years ago. In this contribution, the composition
and origin of the crude conservation film were focused. The samples of the film were analyzed by FTIR, PLM, EDAX, SEM and TEM. The results show that
the film consists mainly of calcium oxalate and there is a microbial involvement in the calcium oxalate film. There is no clear dividing line between the carbonatematrix and oxalates film. The
transformation layer is about 15μm thick. The thin bioinorganic film is very compact non-porous shell and the calcium oxalate is far more acid
resistant than that of calcium carbonate. The forming mechanism was discussed and the chemical bionics of this crude film was also researched.

Key words: cultural relic, conservation, calcium oxalate, bioinorganic film
