空气流速对纤维素类材质文物霉菌病害的影响

Effect of Ambient Air Velocity on Mold Disease of Cellulose Cultural Relics

霉斑是纤维素类材质文物中常见的一类病害。文章通过模拟实验研究纤维素类材质文物(纸质、棉质、竹木质)表面霉斑受空气流速与其表面摩擦系数的影响程度,单因素方差分析结果表明,空气流速对霉斑数量影响显著,且呈现线性递减关系;双因素方差分析结果表明,表面摩擦系数与空气流速有显著交互作用,共同影响霉斑数量,空气流速在0.25 m/s以上时,对霉斑数量有显著抑制效果,可作为文物存放位置的参考指标。

Mildew is a common disease for cellulosic cultural relics.In this paper,through the simulation experiment,the influence degree of air velocity and the friction coefficient of cultural relics surface on the number of mildew was investigated.The results of one-way ANOVA showed that the influence of air velocity on the number of mildew was significant and showed a linear decreasing relationship.The results of two-way ANOVA showed that the surface friction coefficient and the air velocity had significant interaction and jointly affected the amount of mildew.When the air velocity was above 0.25m/s,the amount of mildew was significantly inhibited,which could be used as a reference index for the storage location of cultural relics.
