Designing And Study About Photoinduced Birefringce Experiment Of Polyvinyl Alcohol Films Doped With Azoaromatic Dyes

This paper had the reformation of modern physical experiments in mind, took experimental content and process reformation as the main body, aimed at cultivating the ability and innovating spirit of students, discussed the basic of introducing photoinduced birefringce experiment of Polyvinyl Alcohol films doped with azoaromatic dyes ,and got a experimental project. This paper included five parts. The first part analyzed the actualities of experimental teaching reformation, pointed out the problems, and put forward the reformation project. The second part is about Complex Experiments and Creativeable Experiments .It cited the relation between Complex Experiments and Creativeable Experiments and cultivating the students' ability. It was necessity that introducing Complex Experiments and Creativeable Experiments in teaching. At last, it showed how to doing. The third part introduced the azoaromatic dyes' configuration and optical characteristics. The fourth part was the design of this experiment what mainly introduced the theory of photoinduced birefringce, the sample compounded of azoaromatic dyes, designed the light line of experiment and the reflection factor of photoinduced birefringce .This part indicate that the experiment is adapted for students as Creativeable Experiments and design a concrete scheme for doing out experiment. The fifth part discussed the teaching study of photoinduced birefringce experiment of Polyvinyl Alcohol films doped with azoaromatic dyes .This part analyzed the feasibility about introducing this experiment into modern physical experiments and as Creativeable Expriments .Designing experimental project .At last, discussing the function of this experiment on cultivating the students' ability.
