Problems solved by technology

[0004] However, when using the heuristic algorithm, not only certain chemical-related knowledge is required, but also programming and code writing are required. Therefore, the threshold for using the heuristic algorithm to guide the synthesis of luminescent powder is high and the operation is difficult. Therefore, how can it be convenient? It has become an important research topic to effectively obtain the ratio information of each element in the process of luminescent powder synthesis
