英文摘要	Universal properties of Efimov states for some triatomic systems composed by one light and two heavy atoms are investigated using the finite-range model potentials. We have successfully obtained accurate values of binding energies and sizes for three successive Efimov states. Compared with the predicted scaling constants of the zero-range theory, the ground Efimov states are found to have the largest finite-range corrections. There exists a universal size-binding momentum relation for Efimov states which can be described by the formula R-nk(n) = root(1 + s(0)(2))/3 derived with zero-range approximation. It is found that for the Efimov states that have large scaled sizes, their size-binding momentum relations follow the universal formula well. Our calculations demonstrate that size is an important characteristic in determining the universalities of Efimov states.
