  "abstract": "It is known that local zeta functions associated with real analytic functions can be analytically continued as meromorphic functions to the hole complex plane. In this paper, certain cases of specific (non-real analytic) smooth functions are precisely investigated. In particular, we give asymptotic limits of local zeta functions at some singularities along one direction. It follows from the behaviors that these local zeta functions have singularities different from poles. Then we show the optimality of the lower estimates of a certain quantity concerning with meromorphic continuation of local zeta functions in the case of all smooth functions expressed as $u(x,y)x^a y^b +$ flat function, where $u(0,0)\\neq 0$ and $a,b$ are nonnegative integers satisfying $a\\neq b$.",
