云冈石窟石雕风化的微测深试验

Test with a micro-fothometer at weathering stone sculpture of Yungang Caves

本文是介绍地球物理勘探之一的电法探测新仪器——微测深仪.它经过改装后已被成功地应用到云冈石窟石雕防风化研究中,解决了无损探测石雕表面风化层深度及防护喷涂材料的渗透深度问题,此项试验为国内外石质文物防风化研究中的无损检测开创了一条新路.

The paper introduce the successful application of the Micro-fothometer,a transtformed electrical news survey instrument used in geophysical exploration,to the conservation of weathering stone sculptures in Yungang Caves.It has solved the problem of nondestructive examination of the weathering depth of stone sculptures and the permeated depth of spray coating.The paper explains the principle,the method and the analysis of the test with a micro-fothometer,which has opened a new way for the study of the conservation work on weathering stone relics both in China and abroad.
