The method sets an energy plate between tungsten halogen or xenon arc lamp and a amorphous film deposited on a glass base plate to use heat energy released by amorphous film to heat it to be a polycrystal film. It also can be made by setting a heat radiating plate and a load plate at another side of glass base plate to control distance between them so as to control energy quantity transmission or setting a heat guiding layer and a heat isolation layer between glass base plate and polycrystal film, a heat radiating layer on anotherside of glass base plate and heat receiving layer on amorphous film to control heat guiding dirction for guiding growth direction of crystallization.

The invention discloses a beam-electron beam composite brazing method for high-nitrogen steel, comprising: ① preparing solder paste and coating it on the surface to be welded; Light radiation heating welding is carried out at both ends and the central position; ③The surface to be welded is divided into side A and side B along the vertical line of the welding surface, and side A of the surface to be welded is brazed by electron beam virtual focus welding; ④Use electron beam real focus Soldering and brazing is to be performed on the B side of the welding surface; in parts by weight, the raw material alloy powder of the solder paste consists of 25-28 parts of Pd, 39-46 parts of Ni, 36-39 parts of Cr, 2.8-5.8 parts of vanadium-plated nickel graphite Alkene, 12-15 parts of Mn, 7-11 parts of Re, 6-9 parts of Si and 2-5.5 parts of B. The invention does not melt the high-nitrogen steel parent material during welding, does not lose nitrogen element, is not easy to produce pores, reduces welding heat-affected zone and residual stress, and enhances the mechanical properties of brazed joints.

The invention discloses a xenon lamp, which belongs to the technical field of light source parts. The xenon lamp comprises a lamp body and a lamp holder; the lamp body is fixed with the lamp holder; the lamp body comprises a protective glass tube, a glass core tube, a cathode lead and an anode lead; the glass core tube consists of a discharge tube section, a first core tube section and a second core tube section, wherein the discharge tube section is provided with a discharge cavity and xenon is filled in the discharge cavity; the neighboring part of the first core tube section and the discharge tube section forms a constrictive first neck part; and the neighboring part of the second core tube section and the discharge tube section forms a constrictive second neck part. The xenon lamp is characterized in that: a reflecting film is combined on the outer wall of the first neck part and extended to the core tube shoulder of the first core tube section and the discharge tube section tube shoulder of the discharge tube section. The xenon lamp has the advantages of realizing stable working temperature of a cathode in unidirectional reflection when the lamp body works, ideally increasing the brightness and ensuring that grating is not reduced because of the reflecting film, and reducing the using cost by using a direct-current rectifier.

The invention discloses a method for improving soil. Biomass charcoal is firstly oxidized under the irradiation of a xenon arc lamp, and hydrogen peroxide is sprayed every 6-9 hours during the oxidation period; ditches are dug in the land in winter to form criss-cross ravines; Mix the raw soil from the ditch with the oxidized biochar at a ratio of 1:0.5‑1, apply the mixture of biochar and raw soil in the ditch, and bury and tamp it with soil; cover the tamped ditch For crop stalks, evenly sprinkle animal manure on the crop stalks every 10‑20 days from the date of compaction until the next spring. By modifying the biochar, the invention not only improves the environmental restoration capability of the biochar, but also improves the effect of soil improvement in a low-cost manner.

The invention relates to highly converged high-power adjustable solar simulation equipment. A high-power high-pressure xenon short-arc lamp is used for simulating sunlight; six lamps are uniformly distributed on the periphery of a plane perpendicular to the axis of a middle lamp; and the optical axis of each of the six lamps and the optical axis of the middle lamp form an angle of 15 degrees; each lamp is provided with an ellipsoidal reflective collecting lens; the bright spot of the xenon lamp is adjusted to be positioned at a first focal point of the collecting lens; and light rays emitted by the seven lamps are reflected by the collecting lens and are all converged to a second focal point. The power of the xenon lamp is high, and the optical symmetry of the xenon lamp is also high; and different irradiances under different irradiation areas can be realized by adjusting the number of the lamps which are turned on, the working current of the lamps and the distances from the lamps to a working surface. The highly converged high-power adjustable solar simulation equipment can well simulate various converged real solar irradiations; and a platform which can be flexibly operated is provided for various solar high-grade utilization researches.
