摘　　要：为了解天津博物馆文物保护环境状况,选取天津博物馆展厅内的部分展柜微环境为监测分析对象,利用无线传感监测系统对文物保存环境进行监测,监测日期为2015年1月份,监测参数包括展柜内的温湿度、光照度、紫外线和空气污染物。在数据分析过程中结合文物保存环境监测和控制方面的若干问题进行了探讨,对展柜的调控效果进行了分析。通过分析发现:独立加湿机控制的独立展柜相对湿度介于60.4%~63.3%,相对湿度偏高,建议展柜内配合一定量的调湿材料一起控制;光照度在闭馆时为1.84lx,开馆时介于43.96~52.22lx,开馆时紫外线强度介于0.02~0.06μW/cm2,基本能够满足《博物馆照明设计规范》的要求;展厅内二氧化碳浓度受观众人数的影响,在12∶00~14∶00浓度达到最大值,随后又不断降低,VOC浓度在展柜内存在累积增加现象。调查分析结果可为提高文物保护水平提供参考。In order to understand the status of preservation of current historical relics, a complete system of wireless sensors was built in the Tianjin Museum to monitor the microenvironment inside showcases in January, 2015. Monitoring parameters included the temperature and relative humidity of the air, the light intensity, the ultraviolet radiation and the concentrations of air pollutants inside the showcases. Based on the insitu test results, some critical issues relevant to monitoring and control of the preservation environment of historical relics were evaluated and analyzed. Results showed that the individual showcases had a relatively high humidity ranging from 60.4% to 63.3%, which is not good for preservation of historical relics. It was suggested that hygroscopic materials should be used to control the humidity in the showcases. The illuminance was 1.84lx when the museum closed; when the museum opened, the illuminance and ultraviolet radiation intensity ranged from 43.96 to 52.22lx and from 0.02 to 0.06μW/cm^2, respectively, which meet the requirements of the Code for Lighting Design of Museums （GB/T 23863-2009）.The carbon dioxide concentration in the exhibition hall was affected by the number of persons present, reaching a maximum at 12∶00-14∶00 and then decreasing. The cumulative phenomenon of volatile organic compounds concentration was found in the showcases. The results can provide reference for improving the protection level of cultural relic.
