摘要： <正> 司法实践工作中时有鉴定墨水牌号的要求,但鉴定墨水的牌号是司法鉴定上的难题之一.国外对墨水的研究工作曾有过一些报导.但利用墨水组成的配比不同来鉴定不同牌号的墨水无甚有参考依据.本文试图用可见——紫外分光光度计探讨不同牌号蓝黑墨水的分析和鉴定.

Abstract: The identification of ink is a difficult question in criminal case. In this paper how to apply visible-ultraviolet spectrophotometer into the identification of ink was discussed. There are two maximum absorption top for the blue-black ink in the visible-and ultraviolet region. The wave-length are 288nm and 610am. Tge ratio of their absorption value changes with the type of ink, but doesn't change with the concentration and product date of ink.
