    Abstract: The present invention provides a composition, a gypsum board and their preparation method and the use of ascorbic acid as an anti-sagging additive in a gypsum board. Said gypsum board comprises set gypsum prepared from the composition; while said composition comprises hemi-hydrate gypsum, water and a compound comprising (see above formula) group and no carboxylate groups. The set gypsum prepared from the said composition shows better anti-sagging or deformation resisting property. The gypsum board of the present invention is hardly distorted and has stronger stability even in the condition of high humidity, thus improve the quality of the gypsum board to meet the demands of the customer.

    Abstract: A method and system for detecting and classifying a defect of a substrate, the system including a first channel, including a first illuminating unit to irradiate a light to a substrate and a first imaging unit to take images by sensing a light from the substrate when it is irradiated; a second channel, including a second illuminating unit to irradiate a light to the substrate and a second imaging unit to take images by sensing a light from the substrate when it is irradiated; an image constructing module to construct two images of the substrate using the images of the first and second imaging units respectively; and an image processing module to detect, when the substrate has a defect, that the defect is a defect on or in the substrate, based on a relationship of positions where the defect of the substrate appears in the two images of the substrate.
