Abstract
In this paper, we consider a Kagome-lattise mixed-spin model and show that it is equivalent to an eight-vertex model via decimation and duality transformation. According to the free-fermion approximate solution of the eight-vertex model, the approximate expressions are given for the free energy and critical condition of the model.
