化學命名原則 Principles of Chemical Nomenclature, 1933

Zhèng Zhènwén (鄭貞文), National Institute for Compilation and Translation

Drafted by Zhèng Zhènwén and ratified at Nanjing, this fixed the modern system: every element one character, 氫氧氮氯 for the gases, 矽 for silicon. Later elements follow its rules.
