Abstract：
The concept of moving spin of the relativistic particle is further discussed in the quantum field theory. Two new operators, field quanta spin and moving spin of quantum field system, are introduced. We show that, in virtue of these two operators, some problem in the quantum field theory concerned spin can be neatly settled.
