摘　　要：一、概述敦煌莫高窟开窟断崖属酒泉系砂砾岩,由戈壁小卵石、砂土和其它一些物质混凝而成,呈半胶结状态,成分以砂砾为主。地仗层一般有二层或三层。底层一般为麦草泥,均用窟前土拌合麦草制成。The deterioration in Cave 194 is serious, salt cryatals have grown across the painting or have pushed them away from the walls. Through collating humidity and temperature data and analysing rock and plaster ground component, we found the humidity and active air circulation cause the efflorescence, and their variable fluctuations.
