Technical terminology has a significant role in translation of technical or scientific texts. Unfortunately, most of research in this area has not perceived the urgent need for a model to analyze or shown how translate technical or scientific terminology. In this paper, the researcher attempts to designs a workable model for translation of technical or scientific terminology. The major aim of this model is to provide a real equivalence for both one word terms and above words terms. The design of such a model benefits from different theories about equivalence and approaches that are used for finding real equivalence which translation studies especially technical translation are still lacking.
