摘要
纸质文献酸化是影响其保存寿命的重要原因。本文以我国纸张脱酸专利文本为研究对象,运用主题识别、聚类和频数分析等方法识别专利主题、分析技术要素和实用性研究等内容。研究结果表明,我国现有纸张脱酸专利主要分为脱酸剂、脱酸方法和脱酸设备三类,近87%的脱酸专利属于液相脱酸,脱酸均匀、安全环保、工艺简单和不影响纸张字迹是脱酸专利设计的主要技术目标;近30%的纸张脱酸专利缺失实用性研究,仅为实现某功能而研发,缺少此功能对整个脱酸技术影响的研究;大部分专利(95%)没有完整的安全性测试,安全性表征方式和测量指标不相同,很难客观上评估脱酸技术是否安全可用。
Acidification is an important factor affecting the documents preservation lifetime.This paper takes the deacidification patent texts as the research object.Subject recognition and clustering and frequency analysis are used to analyze the technical elements and practical research.The patents are mainly divided into three categories:deacidification solvent,method and equipment.Nearly 87%of deacidification technology invention are aqueous treatments.The main goals of deacidification technology invention are uniformity,safety,environmental protection,simple process and no influence on paper and handwriting.Nearly 30%of patents do not include practical research,which were invented only for a purpose of achieving a certain function.Most patents do not have comprehensive safety tests,and the safety measurement methods and the results expressed in patents are also different.So it is difficult to objectively assess whether a deacidification technology is safe and usable.
