Because the resistances between the remaining trace and non-remaining trace are different in paper, we can test remaining trace on paper by testing the resistance of invisible fingerprints of sweat.
由于纸张上有无残留痕迹处的阻抗不同，因此可以通过测试纸张有无汗潜指纹纹理处的阻抗，来实现检测纸张上残留痕迹的目的。
This article elaborates on the testing principles and working procedures of the remaining trace on paper (mainly invisible fingerprints of sweat).
