In recent years, research and development in many conservation methods of waterlogged wood is done, and there are some which are actually used for conservation of excavated wooden artifacts like the sugar alcohol method, the higher alcohol method, and the fatty acid ester method. About these new method, research results, such as the suitable impregnating period, size stability, material feeling, and time-dependent change when storage, are reported.On the other hand, most of objects deteriorate while being buried with a certain physical power, modification, breaking and missing has done. In order to give the higher value as archaeological data, after strengthening by medicine impregnation, the work of adhesion, supplementation, etc. must be done in order to reconstruct. Many of objects conserved by their new methods are restored in many cases by the same material and technique as usual regardless of the difference in the adhesion characteristic.In this research, with the adhesiveness test for flexural strength of adhesives it adhesive strength insufficiency of epoxy type resin adhesives is remarkable in especially the fatty acid ester method, and with the test for shear strength of the sheet prepared from adhesive only by punch tool the ethanol gives negative effect. Furthermore, the good result could be obtained, when the sample wood impregnated with the fatty acid ester method was pasted up on the adhesive for use on oily surface.1) It should manage the temperature and the humidity of storage, even if it is the objects that conserved without using water.2) Since the bad influence to adhesives is remarkable, you have to deal with ethanol carefully.3) "Adhesion" becomes a problem most are the PEG method and the fatty acid ester method. The former should settle by storage environment. I think that it is the latter may be able to improve by continual examining an adhesive for use on oily surface.

近年来，人们研究和开发了许多浸木的保护方法，并有一些实际用于保护出土的木制文物，如糖醇法、高级醇法和脂肪酸酯法。对这些新方法，如合适的浸渍时间、尺寸稳定性、材料感觉、贮存时随时间的变化等进行了研究，另一方面，大多数物体在一定的物理力作用下，在埋藏过程中会发生变质、变形、破碎和丢失。为了赋予其更高的考古资料价值，在进行药物浸渍加固后，还必须做好粘接、补充等工作才能复原。许多新方法保存的物品在许多情况下都是用相同的材料和技术修复的，而不管粘合特性的差异。在本研究中，通过对粘合剂的弯曲强度的测试，环氧型树脂粘合剂的粘合强度不足，特别是脂肪酸酯法，而对于仅用冲压工具由粘合剂制备的片材的剪切强度测试，乙醇给出了负面影响。另外，用脂肪酸酯法浸渍的试材粘贴在油性表面用胶粘剂上，也能取得较好的效果。1）即使是不用水保存的物品，也要管理好储存的温度和湿度。2）由于对胶粘剂的不良影响显著，你必须小心处理乙醇。3）“粘附”成为一个问题最多的是PEG法和脂肪酸酯法。前者应根据储存环境而定。我认为，这是后者可能能够通过不断检查用于油性表面的粘合剂来改善。
