Turbulence spectra in superfluids are modified by the
nonlinear energy dissipation caused by the mutual friction between
quantized vortices and the normal component of the liquid.
We have found a new state of fully developed
turbulence which occurs in some range of
two Reynolds parameters characterizing the superfluid flow.
This state displays both the Kolmogorov-Obukhov
-scaling law and a new
"3-scaling law" , each in a well-separated
range of k.
