  The nuclear medium influence on the dihadron neutrinoproduction is
investigated for the first time, using the data obtained with SKAT bubble
chamber. An indication is obtained that the nuclear attenuation of the dihadron
is more expressed for kinematically closest hadron pairs. The experimental data
on the dihadron attenuation and on the ratio of the dihadron to single-hadron
yields are compared with predictions of the two-scale string fragmentation
model.
