Контактные аналоги тождеств Грея для $NC_{10}$-многообразий

We consider contact analogues of Gray identities for almost contact metric manifolds class $NC_{10}$. It is proved that every $NC_{10}$-manifold is a manifold of class $CR_3$. We obtain a local structure $NC_{10}$-manifolds class $CR_1$ and $CR_2$.
