Therefore, this paper aims to explore the relevant control methods by in-depth studying the color development mechanism of SNF, in order to improve its practical value.The basic properties and applications of SNF are introduced, as well as the practical difficulties of the color development problem that have yet to be completely resolved. We discuss the necessary scientific research for this problem and propose a research plan and objectives. Specifically, we plan to explore the color development mechanism of SNF based on its chemical structure and reaction mechanism, and provide theoretical basis for corresponding control methods. At the same time, we will establish a laboratory experimental system and use a series of analysis methods to track the reaction process and obtain preliminary experimental results.精品文档---下载后可任意编辑Finally, we summarize and present prospects for the control of the color development problem of SNF based on the comprehensive analysis of experimental data and literature, to provide a foundation for the optimization of its application.
