Abstract: In 1992, P. Polácik showed that one could linearly imbed any vector field into a scalar semi-linear parabolic equation on $ \Omega$ with Neumann boundary condition provided that there exists a smooth vector field $ \Phi=\left( \phi_{1},\cdots,\phi_{n}\right) $ on $ \overline{\Omega}$ such that

\begin{displaymath} \left\{ \begin{array}[c]{l} \operatorname*{rank}\left( \Phi\... ...tial\nu}=0\text{ on }\partial\Omega\text{.} \end{array}\right. \end{displaymath}

In this short paper, we give a classification of all the domains on which one may find such a type of vector field.
