求翻译：玻璃弯加工后，其每米弦长内拱高的允许偏差为±3.0mm，且玻璃的曲边应顺滑一致；玻璃直边的弯曲度，拱形时不应超过0.5%，波形时不应超过0.3%。是什么意思？

Curved glass processing, its chord length per meter high arch within the allowable deviation of ± 3.0mm, and the glass should be smooth curved line; glass straight edge curvature arch should not exceed 0.5%, the waveform is not should not exceed 0.3%.

After the glass curved processing, in its each meter chord length the rise of arch allowable deviation for ±3.0mm, also nearby the glass tune should be suitable slides consistently; Glass straight edge bending, when arch should not surpass 0.5%, when the profile should not surpass 0.3%.

Glass bending after machining, its chord length per meter high arch of tolerances of ± 3.0mm, should be smooth and curved glass; glass straight edge curvature, Arch should not exceed 0.5%, waveform should not exceed 0.3%.
