Abstract: Disclosed are a multi-stage gravity-type sludge drying apparatus and a sludge drying method using the same. The drying apparatus includes: a dryer, a preheater, a steam generator, a filter, a steam or water separation buffer tank, a steam compressor, a cooling water pump, a sealed discharge device, pipes and valves. The dryer includes several indirect dryer modules. The transportation of sludge in the dryer is achieved by gravity. The inner cavity of respective indirect dryers is filled with high-temperature steam to dry the sludge by indirect heating. The condensate water in the cavity is recycled and fed into the preheater to perform preheating and impurity removal on the wet sludge. The secondary steam generated in the dryer is filtered, compressed and overheated to become a new heat source for indirect heating in the cavity and convection drying at a bottom of the dryer.

Abstract: The present invention provides a method and device for implementing original handwriting trace, and an electronic device. The method comprises: continuously sampling handwriting trace in time order, and detecting location information and the actual stroke widths at the sampling points; for every two adjacent sampling points, determining the former point as the starting sampling point, determining the latter point as the ending sampling point, using a line connecting the two points as the center line of the stroke between the two sampling points, obtaining location information of and the corresponding longitudinal stroke width at each point on the center line, and determining, according to the location information of and the corresponding longitudinal stroke width at each point on the center line, the fill gray value of each pixel in the stroke; and filling, according to the fill gray values, the corresponding pixels, and displaying the pixels.

Abstract: Provided are a method and device for implementing the original calligraphy of handwriting. The method comprises: carrying out a real time sampling of a contact to obtain position information about the sampling point and the pen width at the sampling point; determining a central line of the stroke determined by adjacent sampling points; determining position information about a key point of the corresponding stroke according to the central line and the pen width at the sampling point; dividing the key point of the stroke into groups to determine the type thereof; generating a calligraphy outline of the corresponding stroke by drawing an arc and/or a line according to the type of the key point and the position information about the same; and finally filling the outline for displaying. The displayed handwriting trace has the same calligraphy of handwriting as characters written on paper.
