    摘要： A beamless mechanic-reversing long stroke pumping unit is provided for petroleum production in diverse types of oil fields. Its mechanic-reversing system consists of differentials, brakes, etc. With two differentials assembled together, taper gears inside them perform revolution and rotation, enabling the pumping unit to achieve direction change and speed change mechanically. The stroke length of the pumping unit can reach 8 meters or longer, and the adjustment process is more convenient than most, by merely tuning the position of the proximity switches. Abrasion of the chains typically caused due to resetting of a motor frequently during operation, is eliminated in this pumping unit. The pumping unit has more reliable operation performance, more convenient maintenance, lower costs, better energy saving effects, and can be applied in land oil fields, offshore oil fields, oil wells with low permeability, etc.

    摘要： An imitation ceramic vase manufactured by a method which includes the following steps. (1) Applying a primer layer material on a vase made by a non-ceramic material, and letting the primer layer material to dry. (2) Applying at least one layer of first middle layer material on the primer layer material on the non-ceramic material vase. (3) Applying at least a layer of second middle layer material on the first middle layer material, and letting the second middle layer material to dry, the second middle layer material having a color which is different from that of the first middle later material. (4) Applying a surface layer material on at least one of the first middle layer material and the second middle layer material, and letting the surface layer material to dry. The surface layer material is a polyurethane imitating porcelain surface coating or an ultraviolet imitating porcelain surface coating.

    摘要： For optimal image quality in susceptibility-weighted imaging and accurate quantification of susceptibility, it is necessary to isolate the local field generated by local magnetic sources (such as iron) from the background field that arises from imperfect shimming and variations in magnetic susceptibility of surrounding tissues (including air). We present a nonparametric background field removal method based on projection onto dipole fields in which the background field inside an ROI is decomposed into a field originating from dipoles outside the ROI using the projection theorem in Hilbert space.

    摘要： Provided are a self-cleaning air filtering material and a preparation method therefor. The air filtering material comprises: a submicron fiber layer (2) at an inflow surface for surface filtration, a supporting area (3) for supporting and a mixed area (5) between the submicron fiber layer (2) and the supporting area (3), wherein the mixed area (5) is formed by contacting and mixing part of the fibers in the submicron fiber layer (2) and the supporting area (3) with each other during the one-step formation of the submicron fiber layer (2) and the supporting area (3) by passing through a double-layer headbox.
