Suppose the underlying field is of characteristicp>3.The paper first gives the generators of the even parts of odd Contact Lie superalgebra,then uses the method of computing to determine derivations with-degree-1,-2 or-3 from the even part of the odd Contact Lie superalgebra into the odd part of the odd Contact Lie superalgebra.
