摘要：

It is shown that the previously known N = 3 and N = 4 superconformal algebras can be contracted consistently by singular scaling of some of the generators. For the latter case, by a contraction which depends on the central term, we obtain a new N = 4 superconformal algebra which contains an SU(2) X U(1)4 Kac-Moody subalgebra and has nonzero central extension.
