摘要：
Based on the identification (a(11), a(21), a(22), ..., a(d1), a(d2), ..., a(dd))(T) is an element of Ed(d+1)/2 with symmetric matrix A = (a(ij)) is an element of E-d2, the relation between geometry of the cone of positive semidefinite matrices and the moment cone in four-dimensional Euclidean space E-4 is given. As for the higher dimensional case, we present part of the relation of the two types of cone.
