In this research, including information and photographs, collected from on-site research which had conducted over four years of secular change of artifacts on post-conservation treatment for current condition, were organized and compiled the database.It was remarkable the factors and the results of analysis from samples of artifacts which were found change from on-site research as follows :1.Processes of conservation treatment : Separation of chemical agents on wooden objects, reappearance of corrosion and cracking of metal objects due to defective corrosionproof, separation of calcium salt on resin-supplemented parts, and etc.2.Locations and circumstances of display/storage : Elution of chemical agents, appearance of blackening and stains due to high degree of humidity, decrease in function of conditioning dry and humidity agents, change of surface and color on artifacts, deterioration of supplemented resins, and etc.3.Handling : Breakage and damage during unpacking due to transporting and excess packing, other cases of breakage and damage, adhesion of display sheets and expanded polystyrene to artifacts, and etc.4.Others : Stains from water drops, traces by knots of label strings being off parts of adhesion and restoration, coloring on artifacts itself, and etc.About total 9,121 artifacts were researched and found change on about 1,475 of them. The factors of change were due to display and storage in many cases rather than a matter of conservation treatment. These factors are remarkable that it will be able to be solved by well familiarizing the factors to conservation science researcher and conservation processing staff.As for wooden objects treated with new processes are still expected further improvements in terms of separation of chemical agents on surface of certain wooden objects. However, since size change on wooden objects has not been found it shows that current status of long-lasting stability of artifacts itself were recognized.

本研究将四年多来文物保护处理后的长期变化的现场调查资料和照片整理成数据库，并对现场调查的文物样本进行分析，发现影响因素和分析结果与现场调查相比有如下变化：1.文物保护处理过程：木制品上的化学试剂分离、金属制品因防腐缺陷而再次出现腐蚀和开裂、树脂补充部件上的钙盐分离等。2.展示/储存的位置和环境：化学试剂的洗脱，由于高湿度而出现变黑和污渍，调节干燥剂和湿度剂的功能降低，人工制品的表面和颜色变化，3.搬运：由于运输和过度包装，在打开包装过程中的破损和损坏，其他破损和损坏的情况，显示板和发泡聚苯乙烯粘附到文物上，等等。4.其他：水滴污渍，标签线结的痕迹，粘合和修复的部分脱落，文物本身的着色等。大约总共9个，研究了121件文物，发现其中约1,475件发生了变化。在许多情况下，变化的因素是由于展示和储存，而不是保护处理的问题。这些因素是显着的，它将能够通过保护科学研究人员和保护处理人员很好地熟悉这些因素来解决。至于用新工艺处理的木制品，在某些木制品表面上的化学试剂的分离方面仍有待进一步改进。然而，由于没有发现木制物体的尺寸变化，这表明目前文物本身的长期稳定性得到了认可。
