Quantum entanglements are studied in terms of the invariants under local unitary transformations. A generalized formula of concurrence for N-dimensional quantum systems is presented. This generalized concurrence has potential applications in studying separability and calculating the entanglement of formation for high-dimensional mixed quantum states.
