在现有技术,几何形状等原因影响识别时,可对字体高度进行调整,但必须清晰可辨.
If there is a problem in the recognization or identification of signs caused by the limitations of the available technology or the geometrical shapes, one can adjust them by enlarging the character fonts, but they must be clearly visible.

In the existing technology, geometry etc. affect recognition, can adjust the font height, but must be clearly legible.
