摘　　要：在物理学实验(如光电效应实验)中测定普朗克常数时,对所获取实验数据进行精确处理是整个实验流程的核心要素之一,因为实验数据处理的严谨性与准确性直接关乎实验结果的有效性和可靠性。鉴于传统人工处理方式存在耗时长、精度受限的问题,文章决定应用现代统计编程语言R,通过编写程序的方式来高效且精准地处理光电效应实验中的物理数据,从而确保实验结果的质量与可信度。同时,为探究胚胎干细胞向间充质干细胞分化的过程中的调控机理,生物学领域广泛应用了R语言进行数据分析。通过整合生物信息学手段,文章系统性地分析了8类组蛋白修饰在细胞分化路径中的动态变化及调控模式。这一系列工作不仅揭示了干细胞分化进程中组蛋白修饰背后的精细调控机制,还为表观遗传学层面调控细胞分化与再生的科学研究提供了扎实的分子理论支撑。Accurately processing the obtained experimental data is one of the core elements of the entire experimental process when measuring Plancks constant in physics experiments,such as photoelectric effect experiments,because the rigor and accuracy of experimental data processing directly affect the effectiveness and reliability of experimental results.Considering the problems of long processing time and limited accuracy in traditional manual processing methods,the article decides to use modern statistical programming language R to efficiently and accurately process physical data in photoelectric effect experiments through programming,thereby ensuring the quality and reliability of experimental results.At the same time,R language has been widely used in the field of biology for data analysis to explore the regulatory mechanisms involved in the differentiation of embryonic stem cells into mesenchymal stem cells.By integrating bioinformatics methods,this article systematically analyzed the dynamic changes and regulatory patterns of eight types of histone modifications in the cell differentiation pathway.This series of works not only reveals the fine regulatory mechanisms behind histone modifications in the process of stem cell differentiation,but also provides solid molecular theoretical support for scientific research on epigenetic regulation of cell differentiation and regeneration.
