摘要：
Each of the three commonly investigated perpendicular planar sections is described by two of the three symbols for directions. The two symbols describe the orthogonal directions that are contained in the plane being described. For example, a metallographic examination of the top surface of rolled plate would be an L-LT section because the longitudinal and long-transverse axes lie in that planar section. The proposed notation discriminates between this section and one used to examine the side of the rolled plate, which would be an L-ST section. By convention, the symbol of the direction in which the longer dimension of the wrought product exists is placed first in the notation.
