The application relates to a scalar in-situ calibration method for a three-axis magnetic field reference source in a magnetic shielding environment, and relates to the fields of weak magnetic measurement and quantum precision measurement. In order to solve the problem that the prior art cannot execute in-situ calibration in a closed environment without complex alignment, the application takes the magnetic field modulus data obtained by a scalar magnetometer as the only input, constructs a global error model, and quantifies the mapping relationship between the coil input current and the actual output magnetic field; taking the minimum residual error between the scalar field measurement value and the model calculation value as the optimization target, the LM algorithm is used to inversely solve the coil actual response matrix and the environmental background magnetic field, and the global compensation of the system error is completed; meanwhile, the magnetic coupling distortion effect of the magnetic shielding boundary is calculated by using the mirror method, the coil geometric size is optimized, the magnetic field uniformity and the boundary magnetization effect suppression are balanced from the design source, and finally the accurate mapping model of the input current and the actual output magnetic field is established. The application calibrates the three-axis coil with high precision.

The invention relates to a special-shaped floating strip self-adaptive pressure welding fuse machine which comprises a fuse machine body, a welding mechanism is arranged in the fuse machine body, and an auxiliary limiting mechanism is arranged at the top of the fuse machine body. According to the special-shaped floating strip hot melting machine, a matching structure of the welding mechanism and the auxiliary limiting mechanism is arranged on the hot melting machine body, so that the special-shaped floating strip body can obtain a stable and reliable multiple positioning effect in the welding process, and a second push rod drives a limiting baffle to vertically limit the outer side of a placement table; according to the special-shaped floating strip welding device, the top end of the special-shaped floating strip body is fixed in cooperation with the suction cup in an adsorption mode, displacement and shaking of the special-shaped floating strip body can be effectively limited before welding, and therefore the influence of manual placing errors on the welding quality is reduced; the electric push rod can conduct self-adaptive pressing according to the actual position of the special-shaped floating strip body, and the problem that adsorption is not firm or excessive pressing is caused by height or position deviation is solved.
