The invention discloses a four-rotor aircraft outdoor formation light performance system and a control method thereof. Aircraft hardware setup, control test, host computer compiling and communicationlink design are included, and a main purpose is to conduct formation flight light performance. The position of an aircraft cannot be measured accurately in the outdoor environment, so that the methodprovides practical application measures to eliminate influence of position errors for a flight performance and avoid track generation during formation change during the performance.

To provide a thermal spraying nozzle device and thermal spraying equipment on which a thermal spraying material can be supplied constantly and filming or deposition state can be controlled. In a thermal spraying nozzle device for forming an ultrahigh speed gas stream by introducing carrier gas to the inlet side of a nozzle and then atomizing a thermal spraying material by that gas stream and discharging the atomized thermal spraying material, a storage section (4) for storing molten metal as the thermal spraying material is connected to the inlet side end of the nozzle (2) through a communication passage, the nozzle has a throat portion (2a) for accelerating the introduced carrier gas to supersonic velocity, and a diameter-expanded channel portion (2b) formed on the downstream side of the throat portion toward the outlet direction. The thermal spraying nozzle is characterized in that the metal particles atomized by the supersonic gas stream are cooled down to solidification or semi-solidification state at the diameter-expanded channel portion.

The invention relates to a construction method for supporting templates in the building field, particularly relating to a construction method for supporting the templates at construction joints of a frame structure. The construction method comprises the following steps: top die sticks are arranged on components at two sides of the construction joints; a back arris is made of battens; the back arris is arranged in a through-length manner along a longitudinal direction of the component; the templates at the construction joints are supported at two sides of the back arris and arranged in the construction joints; the back arris and the templates arranged at the two sides of the back arris are connected with connecting pieces and are connected into a whole through the connecting pieces; then holes are drilled at specific positions of the templates at the construction joints; and split bolts are penetrated into the drilling holes to oppositely pull the templates in the construction joints and the templates at outer sides of the components, and additionally, the top die stick is supported in the components so that the templates are effectively fixed; concretes of the components at the two sides of the construction joints are poured at intervals; and at last, the back arris and the templates are dismantled. By using the method, section sizes of the concretes after pouring moulding on the two side structures of the construction joints, protective layer thicknesses of the components and pouring quality of the component concretes can be effectively ensured, thereby facilitating construction and operation.

The heat pipe organic waste liquor treatment equipment is characterized by that the combustion furnace and concentration device are integrated into one body, in which the cold water part of combustion chamber of combustion furnace, internal top wall and four side-walls of U-shaped fly ash settling chamber and heated face of water-cooling partition wall adopt heat-pipe water-cooling structure. Itsconcentration device is divided into two circulating loops respectively formed from heater, separator, circulating pump and balance box, the heat-pipe to end of heat-pipe water-cooling structure is communicated with heater, and the bottom end of heat pipe is communicated with return pipe of heater.
