In contrary to the development and internationalization of science and technology in China,scientific translation is not well-developed yet.As a typical scientific text,physics text is analyzed and examined with a focus on the translation of technical terms and sentences so as to research the internal and external factors of the translator's subjectivity,including horizon,prejudice,knowledge,values,orientation,competence,and so forth.Therefore,the applicability of the translator's subjectivity in scientific translation can be preliminarily evaluated so that some references would be provided for the theoretical and practical research of scientific translation.
