We study the field dependence of the quasi-particle density
of states,
the thermodynamics and the transport properties in the
vortex state of d-wave superconductors when a magnetic field
is applied
perpendicular to the conducting plane, specially for
the low field and the low temperature compared to the upper critical field
and transition temperature, respectively,
and 
.
Both the superfluid density and the spin susceptibility exhibit
the characteristic 
-field dependence, while the nuclear
spin lattice relaxation rate 
and the thermal
conductivity are linear in field H. With increasing temperature,
these quantities exhibit the scaling behavior in 
.
The present theory applies to 2D f-wave superconductors as well;
a possible candidate of the superconductivity is Sr2RuO4.
