تضمن هذا البحث دراسة بعض صنوف المنطويات المترية التلامسية ثلاثية الأبعاد شبه المتنـاظرة
جزئياً. وجدتُ في البداية شروطاً لازمة وكافية حتى يكون منطو متري تلامسي ثلاثي ما شـبه متنـاظر
جزئياً من النمط الأول أو الثاني.
In this paper we study some classes of partially pseudo symmetric contact
three-manifolds .
In sections 3 −1 and 3 − 2 we find necessary and sufficient conditions for
a contact metric three-manifolds to be partially pseudo symmetric of the first
and second type respectively .

In this article we study two classes of contact metric three manifolds,
where first we investigate the necessary and sufficient condition for the contact
metric three manifold to be partially pseudo- Ricci-symmmetric manifold of
constant type.
