利用添改手段变造文件在经济纠纷案件中经常发生,大多数可以以假乱真。由于受各种条件(具体的书写笔、墨水种类、文件形成时间)的限制和影响,不可避免的会出现添改特点。实践中,靠传统的用目力观察、借助放大镜等检验手段已经不能够适应文件检验这门技术发展的需要。我们需要开拓新思路,借助先进的仪器设备,进一步提高我们检验的准确性。 The use of Timmeng means to create documents in economic disputes often occur, most can be true. Due to a variety of conditions (the specific writing pen, ink type, file formation time) and the impact of constraints, inevitably there will be changes in the characteristics of Tim. In practice, by traditional means of observation, with the help of magnifying glass and other means of inspection can no longer meet the document testing the development of this technology needs. We need to develop new ideas, with advanced equipment to further improve the accuracy of our inspection.
