荧光渗透液是荧光渗透检验中的主要工艺辅助材料。渗透检验水平的高低很大程度上取决于渗透液性能的优劣,因而渗透液在渗透检验工艺中占有举足轻重的地位。本文拟对我国荧光渗透液的过去与现状作一简述,以期对其工艺材料的发展有所裨益。 Fluorescent permeate is the main process aid for fluorescence penetration testing. Penetration test level depends largely on the level of permeate performance advantages and disadvantages, and thus permeate in the infiltration test plays a decisive role. This article intends to give a brief account of the past and current status of fluorescent permeate in our country in the hope of benefiting the development of its process materials.
