摘　　要：Based on the quantum invariant theory,the quantum phases,including the total phase as well as its dynamical and geometric parts,of Pancharatnam type are derived for a general spin in a time-dependent magnetic field,without the constraint of adiabatic,cyclic or unitary condition.The geometric meaning of geometric phase is expounded.
