The utility model discloses a kind of needlefish stringing mould, including mutually buckled upper die and lower die, the upper die includes multiple fish body positioning parts and a fish head positioning part, multiple fish body positioning parts and fish head positioning part are arranged along the same linear direction interval, the lower die includes fish body positioning groove, fish head positioning groove and fish tail positioning groove, fish body positioning groove, fish head positioning groove and fish tail positioning groove are arranged along the same linear direction and mutually through, fish head positioning groove and fish tail positioning groove are arranged in the two sides of fish body positioning groove, the position of fish body positioning part corresponds with fish body positioning groove, the position of fish head positioning part corresponds with fish head positioning groove. The utility model is positioned to needlefish by mutually matched upper die and lower die, fish body does not displace when stringing, thus can ensure that stick accurately is worn into fish body, and the case where fish body is worn off or penetrated does not appear, and then improve stringing efficiency and the security of stringing.

This invention relates to the field of materials testing technology, and more particularly to a dual-temperature zone in-situ corrosion and permeation testing device and method. It includes an atmosphere supply unit, a corrosion unit, and a permeation detection unit. The atmosphere supply unit is connected to the corrosion unit, and the gas outlet of the corrosion unit is connected to the permeation detection unit. The corrosion unit includes an insulated cavity, which comprises a high-temperature zone and a low-temperature zone. The high-temperature zone is the solid-state breeder volatilization zone, and the low-temperature zone is the in-situ synergistic corrosion and permeation zone where the material to be tested is placed. A purge gas pipe is installed at the top of the insulated cavity, connected to the atmosphere supply unit, and the high-temperature zone is located within the purge range of the purge gas pipe. The corrosion unit of the device provided by this invention employs a dual-temperature zone independent heating method to simulate the dual-part experiment of lithium volatilization in the high-temperature zone of the solid-state breeder and the dual corrosion of the solid-state breeder when in contact with the blanket structure material, creating an environment more closely resembling the high-temperature operation within the fusion reactor breeder blanket.
