本文对纸张类渗透性客体上混合手印的三种显现方法——DFO、茚三酮和二硫化钼小颗粒悬浮液程序化显现方法进行了研究,阐述了混合手印遗留的性质及DFO、茚三酮和二硫化钼小颗粒悬浮液的显现原理,探讨了这三种显现液在信笺纸、打印纸、牛皮纸、画报纸等不同客体上显现手印时较理想的显现配方和显现步骤,并通过实验对单独使用DFO得到的效果,在DFO的基础上再用茚三酮显现的效果,以及采用DFO、茚三酮和二硫化钼小颗粒悬浮液程序化显现方法得到的效果进行了对比分析。
In this paper, three manifestations of mixed fingerprints on paper-based permeable objects, such as the method of DFO, ninhydrin and molybdenum disulfide small particle suspension, were studied. The properties of hybrid handprint retention and the properties of DFO, Ketone and molybdenum disulfide small particle suspension principle of the show to explore these three liquid in the letterhead paper, printing paper, kraft paper, newspaper and other objects on the Indian handprint appear more ideal formulation and presentation steps, and through experiments The effect of using DFO alone, the effect exhibited by ninhydrin on the basis of DFO, and the effect obtained by the procedure visualization of DFO, ninhydrin and molybdenum disulfide small particle suspension were compared.
