有没有人对于强制性附录20以下的这段话,有比较好的理解
At least two tensile test specimens shall be taken from the plate in the proximity of the hub with one specimen taken from the center third of the plate width as rolled, and the second specimen taken at 90 deg around the circumference from the other specimen.
我画了一个试棒的取法,是不是这样
