The information obtained from the metallographic procedure used in this paper, as compared with techniques of the past, indicates that certain subgroups such as pinhole porosity, microporosity and subsurface porosity require re-evaluation.
与过去的技术相比，从本文所采用的金相检验程序中获得的信息表明，某些子类别，如针孔孔隙率、微孔孔隙率和亚表面孔隙率，需要重新评估。
