AbstractThis paper deals with the materials used in conservation treatments in the first half of the twentieth century for the preservation and consolidation of wooden art objects from the Saxony region in Germany. The use of such materials must be seen as early attempts to find a conservation treatment for wood. The documentation of conservation treatments provides a reference to the application of oils and oil–resin mixtures. The results from the chemical analysis of samples of historic preservatives from the beginning to the middle of the twentieth century (so-called 'Puckelin') carried out by gas chromatography–mass spectrometry (GC-MS) and Fourier transform infrared (FTIR) analysis confirm the use of tung oil as a drying oil, whereas the use of linseed oil cannot be excluded. Colophony and, probably, amber varnish were used as resinous constituents. There are indications that a conservation material dating from the second half of the twentieth century most likely contained rapeseed oil. 相似文献

粉碎“四人帮”后,随着真理标准讨论的深入,“拨乱反正”成为各条战线的共同呼声,文化、教育领域尤其突出。当时,我有幸参与《文学的基本原理》的修订工作,和上海高校从事文艺理论研究和教学的同志多有接触,还到外地（主要是北京、南京）有关单位听取意见。大家一致认为,如果不拔乱反正,不肃清林彪、“四人帮”的流毒,任凭“三突出”、“高大全”之类谬论泛滥,文艺理论的教学和研究将很难继续下去,社会主义文学也就不可能出现真正的繁荣。 相似文献
