静电复印品司法检验是一项比较新的研究课题,复印墨粉的种类鉴别是其中的主要内容。国内这方面的研究尚处起步阶段,目前还很不完善,见诸报道的各种检验手段和方法与实践应用还有较大差距,面临的主要困难是检测仪器的灵敏度达不到要求;多数会破坏样品,同时较难确定纸张成分造成的影响。 Judicial examination of electrostatic copy is a relatively new research topic, the identification of the type of toner is one of the main content. The domestic research in this area is still in its infancy, and is still not perfect. There are still a long way to go for the various test methods and methods reported in various reports. The main difficulty is that the sensitivity of testing instruments can not meet the requirements. Most Will destroy the sample, at the same time more difficult to determine the impact of paper composition.
