This invention relates to the preparation technology of two-dimensional material composites, specifically a method for coating two-dimensional materials onto the surface of non-metallic particles based on a high-temperature growth process. This method is suitable for the large-scale preparation of continuously coated non-metallic particulate materials. The invention employs a three-step method to form continuously coated two-dimensional materials on the surface of non-metallic particles: First, a continuous metal catalyst coating layer with a nanometer-thickness is formed on the surface of the non-metallic particles; then, the coated non-metallic particles are mixed with micron-sized powder of the same metal catalyst composition; next, a continuously coated two-dimensional material film is grown on the surface of the non-metallic particles using a high-temperature catalytic reaction; finally, the metal catalyst is removed, yielding the two-dimensional coated non-metallic particulate material. This invention can achieve the formation of two-dimensional material coating layers on the surface of a large number of non-metallic particles. The two-dimensional materials exhibit continuous, non-overlapping microstructures, high coating rates, and high crystallinity. Furthermore, this method is easily scalable.

The invention discloses a method for obtaining the thickness and refractive index of a film, a test system, a storage medium and application. The method for obtaining the thickness and the refractive index of the thin film comprises the following steps: obtaining an intermediate frequency signal carrying transmission phase information by using two groups of nonlinear transmission line terahertz frequency comb generators and a broadband mixer, and obtaining an actually measured phase curve based on the intermediate frequency signal; constructing an equivalent multi-optical-path interference model of the thin film, performing coherent superposition on multiple reflection components of a measured wave signal in the thin film in a complex field to obtain a complex phase of a total transmission field, and obtaining a phase-frequency change spectrum based on the complex phase as a model phase curve; and an error function of the model phase curve and the actually measured phase curve is constructed, and a parameter combination enabling the error function to take the minimum value is solved by scanning the parameter combination of the refractive index n and the thickness d of the thin film. According to the method, thermal drift or time drift of the phase is avoided, and then calculation errors caused by phase jump are avoided.

This utility model discloses a tracheostomy nebulization and heating device, including a tracheostomy mask, an air delivery tube, a nebulizer, a fine-tuning infusion set, a constant-temperature heater, and an infusion tubing. Both ends of the infusion tubing are connected to the inlets of the fine-tuning infusion set and the nebulizer, respectively. Both ends of the air delivery tube are connected to the outlets of the tracheostomy mask and the nebulizer, respectively. The constant-temperature heater is located on the outside of the infusion tubing. By incorporating the fine-tuning infusion set and connecting it to the nebulizer, the input rate of the humidifying liquid can be controlled by adjusting the fine-tuning infusion set, avoiding the discontinuity of traditional manual water addition, ensuring a stable and sustained humidification process, and reducing airway mucosal irritation caused by humidity fluctuations. The constant-temperature heater on the outside of the infusion tubing heats the humidifying liquid, preheating it before nebulization, preventing cold mist from directly entering the airway and avoiding discomfort caused by inhaling cold air.

The application relates to the technical field of microwave remote sensing, and proposes an adaptive wet troposphere path delay inversion method and system fusing wind speed overlapping partition modeling, multi-scale collaborative sample balancing and model soft fusion. The method comprises the following steps: acquiring multi-source data and preprocessing the multi-source data to obtain to-be-inverted samples; according to a preset threshold, the full-range wind speed of the to-be-inverted samples is divided into a plurality of wind speed subintervals with overlapping transition zones; the to-be-inverted samples are input into trained inversion submodels, the output results of the inversion submodels are weighted and summed according to final fusion weights, and finally, wet troposphere path delay inversion results are obtained; when abnormal wind speed or invalid submodel prediction output is detected, the output result of a pre-trained global unified model is taken as the final inversion result. While guaranteeing overall inversion precision and stability, the application can significantly suppress systematic deviation under sea conditions of extremely low and extremely high wind speed.
