一般情况下,在我们技术员的潜意识中汗潜手印的乳突纹线经“502”胶熏显后应为白色。然而在实际工作中却出现了这样的情况,汗潜手印经“502”胶熏显后的白色纹线并不是由乳突纹线形成,而是由乳突纹线之间的犁沟线形成。本文主要对某些用“502”胶显现的现场手印的白色纹线是否为乳突纹线所形成的问题来进行讨论。
Under normal circumstances, in our technician’s subconsciousness sweat latent handprint of the mastoid ridge line by “502 ” gum smoked after the display should be white. However, in actual work, however, such a situation has arisen. The white streaks after the “502” gum sweat is not formed by the mastoid lines but by the furrow between the lines of the mastoid Line formation. This article mainly discusses some questions about whether the white grain of the spot handprint displayed by “502 ” glue is formed by the mastoid ridge.
