The education in the new era calls for the cultivation of innovative talents. The integration of physics education between high school and university, as an important link to deepen the cultivation of innovative physics talents, should not only focus on the deepening of knowledge but also on the improvement of comprehensive quality. Based on the characteristics of the International Young Physicists' Tournament, a research-oriented competition, and taking "cognition-inquiry-practice-innovation" as the main thread, an integrated multidisciplinary curriculum is developed to create a series of physics courses that combine theory and practice for the high school-university connection. This aims to achieve better integration in terms of quality and cultivate innovative talents.

Three types of color line phenomena generated by optical discs under grazing incidence of incandescent light are analyzed from the perspectives of interference, the combined effect of interference and diffraction, and reflection. This paper takes the generation of green lines as an example, based on the construction of optical discs and starting from different incident modes, discusses the impact of different incident modes on the position of color lines on CD discs, explains the reasons for the generation of three types of color lines, and analyzes the conditions for their generation and the factors that affect them. The theoretical model was validated through experiments. It is found that the generation of the first and second types of color lines is essentially influenced by aperture limitations and affects the form of light intensity distribution. The incident light from above the substrate forms the first type of color lines, which are mainly affected by interference factors. While, the incident light from the side of the substrate forms the second type of color line, which is also affected by interference and diffraction factors. The third type of color line is generated in the line of sight direction due to the reflection effect of the central metal ring.
