Abstract: With the growth of international academic communication, a large number of new terms appearing in scientific fields flow into Mongolian language. Hence it is indispensible for us to regulate and unify terms in Mongolian science and technology. This paper aims to state the general principles and methods for coping with Mongolian terms in sciences and technologies. It is held that new terms appearing in Mongolian language in scientific fields should rather originate from its native language than base on those borrowings or loan words through translation. This paper also maintains that newly introduced scientific terms should be conventional, i.e. the sound of a new-appeared scientific term should conform to its form; as a result, the form should be concerned mainly. When the sound and the form in the same scientific term are different, the sound should be the major concern.

Key words: Mongolian, scientific and technological terminology, standardization principles and methods
