The invention relates to a method for reinforcing a river bank by utilizing dredger fill, belonging to the technical field of foundation treatment. The method provided by the invention comprises the following steps: firstly making a trapezoidal river bank foundation by utilizing steel bars; then respectively mixing dredger fill with cobblestone, quicklime, polymeric organic matters, coarse sand and medium sand, and then sequentially putting in a terrace river bank; and finally, planting vegetations on the reinforced river bank. Embodiments prove that the method reduces the cement content and saves the cost, and the material prepared by the method has an obvious reinforced effect; and by virtue of the design of the trapezoidal river bank, after the river bank is built for 3-5 days, a truck of which the weight is more than 2.5-3.5t can steadily run on the river bank.

The invention discloses a double-channel electrically-controlled electric dimming transmission film with a nano wire cluster electrode. The film comprises a patterned public electrode formed by nano wire clusters closely distributed at a nanoscale interval, a top-surface cathode and a bottom-surface metal nanofilm cathode, wherein the top-surface cathode and the bottom-surface metal nanofilm cathode are distributed at the upper end and the lower end of the patterned public electrode respectively; the top-surface cathode and the patterned public electrode are made of light-transmission films which have nano thicknesses and are made of the same material, and the bottom-surface metal nano film cathode is made of a metal film in a nano thickness; the same optical medium materials in the nano thickness are injected between the top-surface cathode and the patterned public electrode and between the patterned public electrode and the bottom-surface metal nanofilm cathode. Fine electrically-controlled dimming can be performed on transmission behaviors of incident light waves, and the film has the characteristics of applicability to a wide spectral domain and relatively intense light beams, insensitivity to polarization and high dimming response speed.

The invention discloses a working ignition method of a gasification furnace and a working glue gas generation system, and belongs to the technical field of chemical energy resources. The working ignition method comprises the following steps: fixedly arranging a burner for working ignition of the gasification furnace on the flue gas generation system outside the gasification furnace, and generating high-temperature flue gas used for working ignition of the gasification furnace through the flue gas generation system; then, conveying the generated high-temperature flue gas to the gasification furnace through a pipeline so as to achieve working ignition of the gasification furnace. The flue gas generation system comprises a flue gas furnace, a flue gas temperature adjusting device used for adjusting the flue gas temperature, a flame detector used for detecting whether a flame is existent in the flue gas furnace or not, a flue used for conveying flue gas, and a fire watching device. The flue gas generation system can provide the flue gas with proper temperature for the gasification furnace, so that the gasification furnace can be stably heated and the heat utilization efficiency of the gasification furnace can reach more than 99%.

The invention belongs to the related technical field of intelligent control, and discloses a control system for a wheeled robot to automatically walk along a slope center line, which comprises a slopeedge identification module, a target distance identification module, a slope inclination angle identification module, a central controller, a self-adaptive slope inclination angle driving module andthe like. Wherein the slope edge recognition module is used for detecting the slope edge and correspondingly calculating the deviation between the current position of the trolley and the slope centerline, so that the trolley can adjust the self direction to walk along the slope center line; the slope inclination angle recognition module is used for detecting the inclination angle of the robot trolley, and correspondingly, the parameters of the driving module can be configured to enable the trolley to stably run on a slope; and when the trolley approaches the target place, the stop position mark is detected through the target distance identification module, and the trolley can be accurately controlled to realize deceleration parking. By means of the method, effective guarantee can be provided for the wheeled robot to stably crawl along the center line of the slope and accurately stop at a destination.
