From the work of O. Munteanu and J. Wang, we extend their some results to the pseudohermitian (2n+1)-manifold. In fact, according to the Bochner formula in CR manifold, the derivative along to the direction T is the key point whenever we consider the analytic work on CR manifold. Hence, our first work is the vanishing property of T-derivative, and then we have the estimate of eigenvalue on CR manifold.
