在有关原子-分子概念的争论中,一直注意着理论的发展却从不介入争论的本生,在以化学分析为中心的多个领域内深入研究、富有创新,极大地推动了近代化学的发展。他和基尔霍夫共同发现的光谱分析法,为元素的定性鉴定和新元素的发现开辟了一条新路。 In the debate on the concept of atom-molecules, he has been paying attention to the development of the theory but never involved in the controversy of the origin, and has conducted in-depth research and innovation in various fields centered on chemical analysis, which has greatly promoted the development of modern chemistry. . The spectral analysis he and Kirchoff discovered together opened up a new path for the qualitative identification of elements and the discovery of new elements.
