Using some ideas from the theory of positivity preserving semigroups, we establish the strong contraction in the <span class="math inline">\(L^1\)</span> norm. As a consequence, it is proved that the equation with a bounded external force possesses a unique bounded solution on <span class="math inline">\(R\)</span>, which is exponentially stable in <span class="math inline">\(H^1\)</span> as <span class="math inline">\(t\to+\infty\)</span>. In the case of a random external force, we show that the difference between two trajectories goes to zero with probability <span class="math inline">\(1\)</span>.</p></abstract><trans-abstract xml:lang="ru"><p>В статье рассматривается проблема устойчивости потока одномерного уравнения Бюргерса на окружности.
