In order to improve the show rate of the sweat fingerprints on permeability rough objects, the experiment in this article chooses diverse types, consistence and temperatures of Ninhydrin liquor on the rough woody object for the fingerprint color test. The result depicts that 5% Ninhydrin liquor is the best media to show the sweat fingerprint on the rough woody object among the permeability objects.%为提高渗透性粗糙客体上汗潜手印的显出率，对粗糙木质客体上的汗潜手印，分别选用不同种类、不同浓度、不同温度茚三酮溶液进行指纹显色试验，结果5％的茚三酮丙酮溶液对于显现渗透性粗糙木质客体的汗潜手印为最佳。
