The invention discloses a preparation method of a high-activity humic acid high-tower compound fertilizer. The high-activity humic acid high-tower compound fertilizer is prepared from 5%-8% of a coating agent, 80%-85% of a base material, 1.2%-2% of an ammoniating agent, 0.12%-0.2% of a defoaming agent, 6%-10% of humic acid and 1%-2% of biological bacteria. The base material is prepared from the following raw materials in parts by weight: 130 to 210 parts of urea, 60 to 90 parts of monoammonium phosphate, 2 to 3 parts of magnesium nitrate, 7 to 10 parts of potassium chloride and 1 to 2 parts ofpolyvinyl alcohol; the urea-formaldehyde resin coating agent is prepared from the following raw materials in parts by weight: 15 to 25 parts of urea and 25 to 35 parts of formaldehyde. After the humic acid fertilizer is processed according to the steps of the method, the humic acid fertilizer has a remarkable soil improvement effect, a high tower can be used for producing a humic acid compound fertilizer and inhibiting slurry from overflowing through an improved process, the moisture content of humic acid is reduced through pretreatment, the moisture content is low, pulverization, caking andother quality problems are not likely to happen, and a coating agent does not pollute the environment.

A dust removal method for an open-pit mine dumper

The invention discloses a dust removing method of a surface mine dumping plough. A mode that a mist-spraying dust removing method is combined with a spraying dust removing method is adopted. Accordingto the mist-spraying dust removing method, a dust removing air-assisted mist-spraying machine is mounted at the lower part of a discharging arm, and the dust removing air-assisted mist-spraying machine is mounted at the position, away from a material falling point by the 20-meter horizontal distance, of the lower part of the discharging arm. According to the spraying dust removing method, a nozzle is mounted at the head part of the discharging arm, and the nozzle is connected with a dust removing water pipeline. According to the dust removing method of the surface mine dumping plough, the mode that mist-spraying dust removing is combined with spraying dust removing is adopted and applied to a dust removing system of the surface mine dumping plough, spraying dust removing is used for discharging dust removing of the head part, the mist-spraying machine at the lower part of the discharging arm is mounted at the fixed position so as to ensure the facts that the mist-spraying distance isfixed relatively and the mist-spraying machine does not need to be moved and arranged frequently due to moving of the discharging arm, the dust removing method can play a better inhibiting effect on secondary flying dust generated after discharging of the dumping plough, and the practical effect is obvious.

Electro-optical device, method for driving the same, and electronic machine

The invention provides an electro-optical device and a drive method thereof and an electronic device. The electro-optical device can inhibit the color splitting caused by the drive of the color order to achieve the great color development and gray-tone response. The electro-optical device uses the color order drive way of light source for three light sources for processing the full-color development. The liquid crystal drive unit that divides on a temporal axis one field into subfields and that, during the subfields, applies either an on-voltage or an off-voltage to picture elements of a liquid crystal display in accordance with gradation of the picture elements during the one field. A light source control unit sequentially switches the three light sources, and switches at least two of the three light sources at a switching period that is shorter than a time duration required to exhibit, in the picture elements during the one field, gradation of each color corresponding to each of the at least two of the three light sources. The invention controls the shift of the light source which makes the shifting period of the light source is shorter than the liquor crystal composing grey in the pixels. According to the electro-optical device, the invention can inhibit the color splitting caused by the drive of the color order without reducing the brightness to achieve the great color development and gray-tone response.

Shield segment, segment ring, tunnel segment lining, and tunnel

The invention discloses a shield segment, a segment ring, a tunnel segment lining, and a tunnel. The shield segment comprises a segment body; an axial protrusion and a first caulking which are used for axial connection are arranged on a first side face of the segment body; an axial groove and a second caulking which are used for axial connection are arranged on a second side face of the segment body; in the annular direction of the segment body, a positioning protrusion used for annular positioning is arranged on the first annular face, and a positioning groove used for annular positioning is formed in the second annular face; an annular I-shaped steel support is inserted between every two adjacent segment rings; inner wing plates of the I-shaped steel supports are located at the inner sides of the inner rings of every two adjacent segment rings; outer wing plates of the I-shaped steel supports are inserted into caulking seams of the adjacent segment rings respectively; and bolts penetrate through the inner wing plates, the segment body and the outer wing plates. According to the shield segment, the segment ring, the tunnel segment lining, and the tunnel, compared with a traditional segment connecting mode, the axial and annular connection of the segments is jointly borne by the I-shaped steel supports and the segments, so that the connecting effect between the segments is strengthened, and meanwhile the integrity of a supporting system is improved.
