Abstract: Let $ {f_t}(x,y)$ be a real analytic $ t$-parameter family of real analytic functions defined in a neighborhood of the origin in $ {\mathbb{R}^2}$. Suppose that $ {f_t}(x,y)$ admits a blow analytic trivilaization along the parameter $ t$ (see the definition in $ \S1 $ of this paper). Under this condition, we prove that there is a real analytic $ t$-parameter family $ {\sigma _t}(x,y)$ with $ {\sigma _0}(x,y)=(x,y)$ and $ {\sigma _t}(0,0)=(0,0)$ of local coordinates in which the Newton boundaries of $ {f_t}(x,y)$ are stable. This fact claims that the blow analytic equivalence among real analytic singularities is a fruitful relationship since the Newton boundaries of singularities contains a lot of informations on them.
