According to 't Hooft [Class. Quantum. Grav. 16, 3263 (1999)], quantum gravity can be postulated as a dissipative deterministic system, where quantum states at the "atomic scale" can be understood as equivalence classes of primordial states governed by a dissipative deterministic dynamics law at the "Planck scale." In this paper, it is shown that for a quantum system to have an underlying deterministic dissipative dynamics, the time variable should be discrete if the continuity of its temporal evolution is required. Besides, the underlying deterministic theory also imposes restrictions on the energy spectrum of the quantum system. It is also found that quantum symmetry at the "atomic scale" can be induced from 't Hooft's coarse graining classification of primordial states at the "Planck scale." © 2001 American Institute of Physics.
