The invention relates to an overlapped method for a virtual object in AR glasses. The method comprises that the AR glasses are fixedly arranged in a set position in a practical scene, and a practical marker with multiple scales is placed in front of the AR glasses; panoramic scanning is carried out on the practical scene to obtain a virtual scene corresponding to the practical scene; the virtual scene is introduced into a development device, and a video scene shot by the AR glasses is uploaded to the development device; after that the development device enters a debugging mode, the virtual scene and the video scene are displayed in the same interface, and virtual scales in the virtual scene are adjusted to be overlapped with shooting scales in the video scene; and the virtual object is overlapped to a target position in the virtual scene, an overlap range parameter in overlapping the virtual object in the virtual scene is obtained, and the virtual object and the overlap range parameter are sent to the AR glasses. Thus, the practical scene corresponding to the video scene can be restored highly effectively, and the virtual scene displayed by the AR glasses has a better display effect.

The present invention relates to a method and a device for the heat treatment of welds. To improve and further develop the heat treatment of the weld and the joining weld regions (6, 7) before and behind the actual welding by means of a laser, which is carried out during welding of steel sheets (2) to minimize the risk of crack formation or alteration of the microstructure in the region of the weld, it is proposed according to the invention that the heating of the region of the weld (6, 7) be carried out by means of a multiply stepped line inductor (4, 5) which can be set in a defined way andhas zones of different power densities and is configured with a multiple division of its conductor loop lengths and / or with different plating of the conductor loops and / or with a plurality of spacingsteps from the steel strip (2). Here, a steeper temperature rise occurs in the first heating stage than in the subsequent heating stage.

The invention discloses a technique for measuring the heat release rate of materials in a reactor. The thermal compensation method is used to measure the heat release rate of the material based on the equivalent heat equivalent principle of temperature difference. The calorimeter designed by this technology is mainly composed of two measurement bridges and a comparison bridge with the same shape and material. The sample material is fixed on the measurement bridge, and controllable electric power is input on the comparison bridge to make the temperature difference between the measurement points on the comparison bridge The temperature difference between the measuring points corresponding to the measuring bridge is equal, and the input controllable electric power divided by the sample mass is the heat release rate of the sample to be tested. In order to allow the calorimeter to be placed in a static coolant and to increase its safety, the calorimeter has a cold junction with enhanced heat transfer capability. In order to weaken the influence of gas heat conduction and radiation heat transfer on the measurement results, the calorimeter adopts a double cladding design with a gap between the two claddings. This technology effectively overcomes the influence of material properties on the measurement results due to changes in environmental parameters and reduces the impact on The correction of the experimental results realizes the direct measurement of the heat release rate of the material.

The invention relates to an arrangement method of a tower-type boiler high-temperature reheater container system, which can reduce the thermal deflection among the screens of reheater effectively according to the operation characteristic of the tower-type boilers. The arrangement method comprises: arranging a resistance device in a lead-out steam guide pipe, close to the center of the boiler, of the tower-type boiler reheater outlet container, the distribution of inter-screen flow is changed by changing the difference between the lead-out flows on two sides of the reheater system outlet container so as to be matched with the distribution of inter-screen heat release difference on a smoke side to reduce inter-screen thermal deflection.

A method for making a Fischer-Tropsch synthetic reaction stable. A catalyst for Fischer-Tropsch synthesis is activated and enters an initial phase of a Fischer-Tropsch synthetic reaction; at the reaction initial phase, an inert medium is introduced into synthesis gas so as to allow a mixture flow containing hydrogen, carbon monoxide and the inert medium to contact with the Fischer-Tropsch synthesis catalyst bed layer for reaction; with the activity of the Fischer-Tropsch synthesis catalyst being in a steady state, the amount of the inert medium in the reactant flow is decreased gradually till the Fischer-Tropsch synthetic reaction is in a steady-state phase, wherein at the reaction initial phase, the reaction condition is the same as the reaction condition at the steady-state phase. With the method, the risk of overtemperature at the reaction initial phase is reduced; hot spot areas are reduced; the Fischer-Tropsch synthetic reaction can go into a steady-state phase stably; and guarantee for the long-period running of Fischer-Tropsch synthesis equipment is provided.

The invention provides a Fischer-Tropsch synthesis method. The invention adopts two Fischer-Tropsch synthesis reaction vessels in serial connection, wherein the first Fischer-Tropsch synthesis reaction vessel is a slurry bed reaction vessel, and the second Fischer-Tropsch synthesis reaction vessel is a fixed bed reaction vessel. Outflow materials of the first Fischer-Tropsch synthesis reaction vessel fully or partially enter the second Fischer-Tropsch synthesis reaction vessel for carrying out synthesis reaction, and H2 and / or CO is injected between the two Fischer-Tropsch synthesis reaction vessels for regulating the molar ratio of H / C at an inlet of the second Fischer-Tropsch synthesis reaction vessel.
