It is shown that the time‐energy uncertainty relation can be combined into the position‐momentum uncertainty relation covariantly in the quark model of hadrons. This leads to a Lorentz‐invariant form of the uncertainty relations. This model explains that the quark model and the parton model are two different manifestations of the same covariant model. In particular, this covariant model explains why the coherent amplitudes in the quark model become incoherent, after a Lorentz boost, in the parton model. It is shown that this lack of coherence is consistent with the present form of quantum mechanics.
