研究目的
To develop a theoretical model that explains the transition between different structural states of a solid surface under the influence of laser radiation, focusing on the self-consistent behavior of relaxation field, stress fields, and concentration of relaxation zones.
研究成果
The theoretical model successfully describes the transition between different states of a solid surface under laser radiation through the self-consistent behavior of relaxation field, stress fields, and concentration of relaxation zones. The analysis reveals that the formation of relaxation zones can occur discontinuously by the mechanism of a first-order phase transition, depending on the external load related to the intensity of laser radiation.
研究不足
The study is theoretical and does not involve experimental validation. The model's applicability to specific materials and conditions under laser radiation is not tested.
1：Experimental Design and Method Selection:
The study employs a theoretical model based on the Lorentz system to analyze the transition between stable states of formations on the surface of a solid under laser radiation.
2：Sample Selection and Data Sources:
The model is applied to a general case of a deformable solid without specifying particular materials.
3：List of Experimental Equipment and Materials:
Not applicable as the study is theoretical.
4：Experimental Procedures and Operational Workflow:
The analysis involves setting up a system of nonlinear differential Lorentz equations to describe the time dependencies of the relaxation field, stress fields, and concentration of relaxation zones.
5：Data Analysis Methods:
The study uses dimensionless quantities to simplify the system of equations and analyzes the steady-state solutions to understand the transition mechanisms.
