In this paper, a finite-dimensional Lie superalgebra
K
n
,
m
over a field of prime characteristic is constructed. Then, we study some properties of
K
n
,
m
. Moreover, we prove that
K
n
,
m
is an extension of a simple Lie superalgebra, and if
m
=
n
−
1
, then it is isomorphic to a subalgebra of a restricted Lie superalgebra.
