In order to formulate a reasonable protection and restoration plan， various modern analytical techniques were employed to analyze the physical properties of the paper， and the fiber composition and processing techniques were inferred according to the observed fiber morphology. In response to the contradiction between the large amount of ancient books and limited repair capacity， a classification repair plan was formulated based on preservation requirements. During the conservation work， sulphuryl fluoride fumigation was carried out before restoration， and the customized folding cases were made after the restoration. The results showed that the cover paper， label paper， and inner pages of the books were bamboo paper without coating. The average pH value of the ancient book paper was 5.5， indicating mild acidification. Given the strength of the paper， deacidification treatment was not performed during the restoration. In the actual restoration process， five volumes were selected for complete restoration that one of repaired page by page and flattened， four of underwent partial repair， and remaining volumes had covers’ repaire and the threads’ replacement.]]> 2024/10/25 0:00:00 LIU Jianhui,YANG Qin,CHENG Xiaolin,JIAO Jiabao,BAI Xuesong,SUN Bijia 8true 2024/10/25 0:00:00 SHI Qian 7true 2024/10/25 0:00:00 YAN Zhipei,YI Xiaohui,ZHANG Ming,LONG Kun 6true Aspergillus glaucus.]]> 2024/10/25 0:00:00 SHAO Yongmei 5true 2024/10/25 0:00:00 ZHAO Xiaolong,ZHANG Xiaolong,CHEN Zifan,ZHOU Songluan 4true 2024/10/25 0:00:00 WANG Fan,LIU Hua 3true 2024/10/25 0:00:00 YANG Fan 2true 2024/10/25 0:00:00 ZHOU Huahua,QIU Wan,DING Chunli 1true
