As Lavoisier advocated in the Preface of his Elements of Chemistry, "…we cannot improve the language of any science without at the same time improving the science itself; neither can we, on the other hand, improve a science without improving the language or nomenclature which belongs to it", the importance of the proper usage of nomenclature for the education and the development of science is beyond any doubt. Nevertheless, it has been over a hundred years since the inception of importing Western classics via translation at the end of the 19th century, certain choices of Chinese physics terminology need to be reexamined closely. In this article, attempts are made to summarize and propose in general principles, together with exemplary explanation, for determination of the proper usage of nomenclature in physics. These are: 1. principle of evolution, 2. principle of consistency, 3. principle of contextual conformity, 4. principle of elucidation, 5. principle of correction, 6. principle of adaptation, 7. principle of incorporation.
