摘要：
The models of rf-driven Josephson junctions are investigated as the perturbed systems. It is shown that the heteroclinic orbits corrected by perturbations are stable if some relations between the initial constants and system parameters are satisfied, which leads to Melnikov chaos: To stabilize chaos one has to make the control parameters fitting the relations. The result is compared with the previous numerical work and a good agreement is found.
摘要：
Based on not only the ideas of phenomenological investigations about the internal friction of crystalline materials but also the studies on the internal friction laws of noncrystalline materials during structural relaxation processes in recent years, the method of making relaxation cell is put out. In the method, traditional mechanics parameter model and two-level model are unified, so phenomenological studies on the internal friction of noncrystalline materials during structural relaxation processes are made and a new relaxation law is formed.

摘要：
Information concerning the effect of pre-heat treatments upon the internal friction behaviour of amorphous palladium silicon alloys during multiple isothermal annealing at different or same temperatures was presented. The reversible behaviour of structural relaxation was observed experimentally.
