文物保存攸關文化傳承，我國書畫文物以紙絹為本，易受環境影響及本身結構薄弱，在維護方面有其特質。歷代本諸經驗雖有所成，但如加礬於素材，未審其弊，使熟絹藝品難於久存，即為明證。迺以理化觀點試解其因。紙絹一如所有高分子聚合物，易受光氧化作用，生成含氧自由基，進行連續反應，導致強度減弱，再加環境濕度及細菌之相乘效應，變本加厲。除在環境方面防患於未然，更宜以輓近科技知識加強維護，針對傷害文物之過氧及過氫氧自由基，予以處理，使用光安定劑於文物素材，諸如揭裱重裝時，與糊料併用或將溶液噴霧物面，以抑止光氧化反應之進行。至於素材杇損特甚者，可採取聚合作用以求保固。此外，利用非破壞性分析，如化學閃光法以監測文物受損程度及處理成效。當務之急則為研討其可行性及系統設計。

　　　　　Chinese painting and calligaphy works represent the subtle traditions of culture in China. The artists express the concept, humanity, and aesthetic attitudes on paper and silk. However, these materials are delicate with limited resistance to environmental changes, microbial attacks, stresses and the last, in the storage and exhibition of art works, photo-oxidation reactions proceed silently under the inluence of free-radical chain reactions initiated by light and atmospheric oxygen. On the substrate materials, the effect can be more pronounced through a combination of unfavourable factors cited above, or by additives used in the treatment. In art history, masterpieces from alum-im-pregnated silk and paper were reported for untimely disintegrations. One purpose of this paper is to investigate the adverse effect of alum, potassium and the action of sulfate reducing bacteria on the substrates. As fas as photo-oxidation is concerned, the essential step is to apply light stabilizer for protection. It is necessary to stop the chain reactions by peroxide and hydroperoxide radicals imbedded in the matrices of silk and paper. In monitoring the degree of photo-oxidation and efficiency of trearment, the use of chemiluminescence as an analytical tool is suggested for checking without taking samples. For art works close to the brink of destruction, attempt to use monomer impregnation followed by radiation induced polymerization is considered to be a versatile approach in consolidating the structures of silk or paper.
