The invention provides a linear evaporation source. The linear evaporation source comprises a heating cavity for accommodating a vapor deposition material, a mixing cavity which is positioned above the heating cavity and is used for mixing steam of the vapor deposition material, and a passage for communicating the heating cavity and the mixing cavity, wherein one end of the mixing cavity is communicated with the heating cavity through the passage, and a plurality of nozzles for spraying the steam of the vapor deposition material are arranged at the other end of the mixing cavity; heaters are respectively arranged on the peripheries of the heating cavity, the mixing cavity, the passage and the nozzles. According to the linear evaporation source provided by the invention, the heating of the vapor deposition material and the mixing of material steam are carried out in two independent spaces, so that the thickness of a vapor deposition film can be controlled to be higher in uniformity.

The invention provides a large-torque continuous rotating type SMA motor. At least two drive units are installed on a main shaft in a series connection way, and the main shaft is driven to continuously rotate by sequentially actuating each drive unit. Each drive unit mainly comprises an SMA wire, a spring, a rotating disk, a ratchet wheel and a ratchet pawl, wherein one end of the SMA wire is installed on a ceramic support seat by a flattened stainless steel pipe, and the ceramic support seat is installed on an upper plate of the motor; the other end of the SMA wire is installed on the rotating disk by a ceramic pulley; one end of the spring is hung on the rotating disk, and the other end is installed on a bottom plate by an adjusting bolt; the ratchet pawl is installed on the rotating disk, simultaneously pressed by a spring sheet installed on the rotating disk and meshed with the ratchet wheel; and the ratchet wheel is installed on the main shaft by a key groove. The drive units areformed by the joint actuation of the SMA wire and the spring, and the output torque is large; the SMA wire is used as a drive element and has high energization heating efficiency; and the ratchet wheel and ratchet pawl connection is adopted between the main shaft and the rotating disk, and the one-way rotation is realized.

The invention discloses a sheet metal cooling and heating rapid cycle aging forming method and device, relates to the technical field of sheet metal forming, comprising the following steps: horizontally put the sheet material after solid solution treatment into a concave die, and then press the male die on the sheet metal Put the forming mold on the pressure device to apply pressure, tighten the pressure-holding nut to maintain the pressure of the forming mold on the sheet; start the temperature control system and enter the cooling and heating cycle aging forming process: At this time, the forming mold is at room temperature, and the heating device Start to make the forming mold heat up to a temperature slightly higher than the aging temperature; after reaching the set temperature, the temperature control system will turn off the heating device and start the cooling device to cool the forming mold to room temperature; after the first cycle process is completed, it will enter a continuous cycle In the aging process, after the last cycle process is completed, the sheet can be taken out after cooling to room temperature, and the formed parts can be obtained. The invention reduces aging forming time, improves forming performance and has better forming effect.

The invention discloses a device and a method for continuously preparing charcoal, which relate to the field of comprehensive utilization of forestry and agricultural residue resources. The device comprises a hollow annular furnace body, wherein a material feeding and discharging chamber is communicated to the outer side of the annular furnace body; a material transferring track is commonly arranged in the annular furnace body and the material feeding and discharging chamber; a feeding and discharging end of the material transferring track parallelly penetrates through the material feeding and discharging chamber to the outside; a material tank automatically enters the material feeding and discharging chamber through the material transferring track, and is preheated in the material feeding and discharging chamber; the preheated material tank enters the annular furnace body so as to be carbonized; the carbonized material tank automatically enters the material feeding and discharging chamber through the material transferring track; at the moment, the carbonized material tank preheats forestry and agricultural residues in a non-carbonized material tank, the carbonized material tank is conveyed outside the material feeding and discharging chamber through the material transferring track, and finally, the charcoal in the material tank is taken out. The device provided by the invention can be used for continuously producing without the need for flameout, the production efficiency is high, and the carbonization energy consumption is reduced.

The invention provides a method and system for enriching trace heavy nuclear hydrogen isotopes in hydrogen isotopes by a hydrogen displacement adsorption method, which belongs to the field of chemical separation.
