  In this paper, we partially solve Yau' Conjecture of the first eigenvalue of
an embedded compact minimal hypersurface of unit sphere $\mathbb{S}^{n+1}(1)$,
i.e., Corollary 1.2. In particular, Corollary 1.3 proves that the condition
$\int_{\Omega_{1}}|\nabla u|^{2}=(n+1)\int_{\Omega_{1}}u^{2}$ is naturally true
and meaningful in Corollary 1.2.
