  We show, using quantum field theory, that performing a large number of
identical repetitions of the same measurement does not only preserve the
initial state of the wave function (the Zeno effect), but also produces
additional physical effects. We first demonstrate that a Zeno type effect can
emerges also in the framework of quantum field theory, that is, as a quantum
field phenomenon. We also derive a Zeno type effect from quantum field theory
for the general case in which the initial and final states are different. The
basic physical entities dealt with in this work are not the conventional
once-perfomed physical processes, but their $n$ times repetition where $n$
tends to infinity. We show that the presence of these repetitions entails the
presence of additional excited state energies, and the absence of them entails
the absence of these excited energies. We also show that in the presence of
these repetitions the Schroedinger equation may be derived from the functional
generalization of quantum mechanics.
