摘要
高原地区寒冷干燥,昼夜温差大,日照强,为了研究高原博物馆环境参数的变化情况,对拉萨市某博物馆库房经书柜内外进行为期10个月的温湿度、CO2浓度、VOC浓度、光照强度和紫外线强度监测,分析了环境参数的变化规律、特征和影响因素.结果表明:柜内温湿度随柜外温湿度季节性变化而变化,柜内温湿度日变化小,温湿度平均日较差分别为0.73℃和0.83％,柜外为1.6℃和4.25％,经书柜可以有效保护古籍文物不受柜外环境温湿度日波动的干扰;柜内外温湿度日较差与季节无显著的相关关系,该博物馆建筑围护结构隔热性能较好;温度日较差与CO2浓度日较差呈显著的正相关关系,即库房内工作人员越多,温度日较差越大;柜内VOC容易富集,浓度更高,建议放置活性炭等吸附材料;光照和紫外线强度极低,当前经书柜整体有利于保存.
Abstract
The plateau area is characterized by cold and dry conditions,large diurnal temperature variations and strong sunlight.To study the variations in environmental parameters in highland museums,a ten-month monitoring of the temperature,humidity,CO2 concentration,VOC concentration,light intensity,and ultraviolet intensity was conducted both inside and outside a scripture cabinet of a museum in Lhasa.We accomplished this by analyzing the patterns,characteristics and influencing factors of environmental parameter changes accordingly.The results show that the temperature and humidity inside the cabinet changed seasonally with the external conditions but exhibited smaller diurnal fluctuations,with average daily variations of 0.73℃ and 0.83 percentage points,respectively,compared with 1.6℃ and 4.25 percentage points externally.The scripture cabinet could effectively protect the ancient manuscripts from daily fluctuations in external temperature and humidity.There was no significant correlation between the diurnal variations in temperature and humidity and seasons,indicating good thermal insulation properties of the museum's structural enclosure.There was a significant positive correlation between the diurnal variations in temperature and the CO2 concentration,suggesting that a higher number of staff in the storage area led to a greater temperature variation.The VOC in the cabinet was easy to enrich,featuring a higher concentration,and it is recommended to place adsorbent materials such as activated carbon.The light intensity and ultraviolet intensity were extremely low.The current cabinet was generally beneficial to scripture preservation.
