【摘要】 抗战时期,大后方出版了大量的期刊。这些期刊有许多是用手工纸印刷的。该文取样研究表明,这个时期的手工纸与机制纸期刊的破损状况差异很大:机制纸期刊酸度高,纸张变色,少有虫蛀;手工纸期刊接近中性,没有变色,但虫蛀严重。纸张酸度高,会导致纤维素的长链易断为短链,再过几十年,这批机制纸期刊有可能一触即碎。手工纸期刊的酸碱度接近中性,应可以保存几百年,但要及时采取有效的防虫灭虫措施,否则有被虫吃光的危险。更多还原

【Abstract】 During the period of Anti-Japanese War,a large number of periodicals were published in the rear of war.Many of them were made of hand-made paper.The research on samples from the collection shows that the damaged conditions of the two kinds of periodicals are very different.The machine-made paper periodicals are acidified severely,discolored,but not moth-eaten.The hand-made paper periodicals are acidified lightly,not discolored,but moth-eaten.Severe acidification will lead to the break of cellulose from long molecular chain to short chains.A few decades later,the machine-made paper periodicals may probably break into pieces at a touch.On the contrary,hand-made paper periodicals can exist for hundreds of years because the pH closes to neutral while timely and effective measures should be taken to avoid being moth-eaten.更多还原
