%X The problem of norm invariance property of two-spin half systems is discussed in this paper. Based on the basis of tensor space, the Liouville-von Neumann equation of two-spin half systems is transformed into the coordinate differential equation by using matrices of adjoint operators of two-spin half systems. Then, norm invariance property of trajectory of the transformed coordinate differential system is established.
