  Stable pairing states of superfluid 3He in aerogel are examined in the case
with a global uniaxial anisotropy which may be created by applying an uniaxial
stress to the aerogel. Due to such a global anisotropy, the stability region of
an ABM pairing state becomes wider. In an uniaxially stretched aerogel, the
pure polar pairing state with a horizontal line node is predicted to occur, as
a 3d superfluid phase, over a measurable width just below the superfluid
transition at T_c(P). A possible relevance of the present results to the case
with no global anisotropy is also discussed.
