      <abstract>We investigate conditions which provide equi-continuity of bounded on order intervals families of semi-norms. This investigation develops further recent results on uniform boundedness of bounded on order intervals families of linear operators from an ordered Banach space with a closed generating cone to a normed space. More precisely, we prove that a family of semi-norms on an ordered Banach space with a closed generating cone is equi-continuous if it is equi-bounded on order intervals. In particular, every semi-norm on an ordered Banach space with a closed generating cone is continuous, whenever it is bounded on order intervals. It leads to straightforward proofs of above-mentioned recent results on automatic continuity of certain linear operators and on uniform boundedness of some families of linear operators. Furthermore, we prove that every order-to-topology bounded set of linear operators from an ordered Banach space with a closed generating cone to a locally convex space is equi-continuous.</abstract>
      <trans-abstract xml:lang="ru">Исследуются условия эквинепрерывности ограниченных на порядковых интервалах семейств полунорм. Данное исследование развивает недавние результаты о равномерной ограниченности &#13;
 ограниченных на порядковых интервалах семейств линейных операторов, действующих из упорядоченного банахова пространства с замкнутым порождающим конусом в нормированное пространство. Более точно, доказывается, что семейство полунорм на упорядоченном банаховом пространстве с замкнутым порождающим конусом эквинепрерывно, если оно эквиограничено на порядковых интервалах. В частности, полунорма на упорядоченном банаховом пространстве с замкнутым порождающим конусом непрерывна, если она является ограниченной на порядковых интервалах. &#13;
Это ведет к прямым доказательствам вышеупомянутых результатов об автоматической непрерывности ряда линейных операторов, а также равномерной ограниченности некоторых семейств операторов. Например, доказывается, что всякое топологически совместно ограниченное на порядковых интервалах семейство линейных операторов, действующих из упорядоченного банахова пространства с замкнутым порождающим конусом в локально выпуклое пространство, является эквинепрерывным.</trans-abstract>
