The problem <strong>of</strong> the mixed quark-hadron matter, that can arise at nuclear collisions, is<br />
addressed. It is shown that there can exist several different kinds <strong>of</strong> such a mixed matter.<br />
Be<strong>for</strong>ecomparing theoretical results with experiments, onehastoanalyze thermodynamic<br />
stability <strong>of</strong> all these mixed states, classifying them onto unstable, metastable, and stable.<br />
Only the most stable mixed state should be compared with experiment. In addition<br />
to thermodynamic instability, there exists dynamic instability occurring in a mixture <strong>of</strong><br />
components moving with respect to each other. This effect, called counterflow instability,<br />
has also to be taken into account, since it can lead to the stratification <strong>of</strong> mixed matter.<br />
