The invention discloses a turnable-heating-tube mounting structure and an electric oven and aims to solve the problem that the side walls, on which a heating tube is arranged, of the inner container of a conventional electric oven are hard to clean. The turnable-heating-tube mounting structure comprises a box body and a heating tube mounted in the box body, wherein the box body is provided with a wall surface; the heating tube is mounted close to the wall surface and arranged in the box body in turnable manner; and in the turning state, at least part of the heating tube deviates from the wall surface. The invention also provides the electric oven with the mounting structure. The two ends of the heating tube are rotatably mounted on two side walls of the inner container of the electric oven, and the heating tube can rotate by a preset angle along the axis where the two end parts of the heating tube are positioned, so that the wall surface, on which the heating tube is fixed, of the inner container is exposed outside to be conveniently cleaned.

The invention relates to a four-junction solar cell structure with high radiation resistance and a preparation method thereof. The structure comprises a metal thin film substrate, a high-reflectivity metal layer, a dielectric layer, and a thin four-junction epitaxial layer arranged in sequence; the method includes adopting Thin four-junction epitaxial layer is prepared by metal-organic chemical vapor deposition technology; an omnidirectional reflector is prepared on the surface of the epitaxial wafer, and a dielectric layer is grown by plasma-enhanced chemical vapor deposition technology, and periodic micropores are etched on the dielectric layer. The metal material with high reflectivity is deposited on the surface; the metal thin film substrate is prepared on the surface of the omnidirectional reflector by electroplating technology; the gallium arsenide substrate and the GaInP corrosion stop layer are respectively removed by chemical etching. Beneficial effects of the present invention: the thickness of the four sub-batteries is greatly reduced, the loss of charged particle radiation to the four-junction battery is greatly reduced, the defect density is reduced, and the radiation resistance of the four-junction battery is improved, thereby promoting the four-junction Application of batteries in aerospace field.
