摘　　要：指纹作为法定证据的一种,在侦查和诉讼阶段发挥着重要的作用。根据指印遗留物质的不同,显现方法也有所不同。物理显影液是处理潮湿渗透性客体上潜在指印的标准方法,针对指印当中的脂类物质,能够表现出很优异的效果,但物理显影液存在着固有的缺陷。油红O自应用到法庭科学领域以来,由于其在一定程度上比物理显影液更实用、性价比更高,受到了广泛的关注。通过对油红O的发展过程进行了简单的概括,总结了油红O的原始配方以及改进配方在各个方面的优缺点,对比油红O和物理显影液两种方法在多种条件下的显现效果,并对油红O在手印显现方法应用次序中的位置进行了归纳,为油红O的发展、使用以及推广提供一定的参考依据。As a kind of legal evidence,fingerprints play an important role in the investigation and litigation stage.According to the different substances deposited by fingerprints,the methods of fingerprints development are also different.Physical developer is a standard method to deal with latent fingerprints on wet and porous objects.It can show excellent results for fingerprints in lipids,but physical developers have inherent defects.Since Oil Red O was applied to the field of forensic science,it has received widespread attention because it is more practical and cost-effective than physical developer to a certain extent.In this article,the development process of Oil Red O is briefly summarized,the advantages and disadvantages of the original formula and the improved formula of Oil Red O are summarized in various aspects,and the appearance of two methods of Oil Red O and physical developer under various conditions are compared.In addition,the effect and position of Oil Red O in the application sequence of fingerprint development methods are summarized.This article provides a certain reference for the development,use and promotion of Oil Red O.
