  Inspired by Caffarelli-Kohn-Nirenberg, Fefferman and Lin, we try to
investigate how to control the set of large value points for the strong
solution of Navier-Stokes equations. Besov-Lorentz spaces have multiple indices
which can reflect complex changes of the set of the large value points. Hence
we consider some properties of Gauss flow, paraproduct flow and couple flow
related to the Besov-Lorentz spaces. When dealing with Lorentz index, we use
wavelets and maximum norm to describe the decay situation in the binary time
ring and to define time-frequency microlocal maximum norm space. We use maximum
operator, $\alpha$-triangle inequality and H\"older inequality etc to get
accurate estimates. As an application, we get a global wellposedness result of
the Navier-Stokes equations where the solution can reflect how the size of the
set of large value points changes.
