In this paper, we obtain the local uniqueness of a single peak solution to the following Kirchhoff problem $$ - \left( {{ \in ^2}a + \in b\int_{{{\rm\mathbb{R}}^3}} {{{\left| {\nabla u} \right|}^2}{\rm{d}}x} } \right)\Delta u + u = K\left( x \right){\left| u \right|^{p - 1}}u,u > 0,x \in {{\rm\mathbb{R}}^3}$$ for $ \in > 0$ sufficiently small, where $a,b > 0$ and $1 < p < 5$ are constants, $K:{{\rm\mathbb{R}}^3} \to {\rm\mathbb{R}}$ is a bounded continuous function. We mainly use a contradiction argument developed by Li G, Luo P, Peng S in [20], applying some local p...
