✦ Synopsis

By path integration method developed by Brusov and Popov earlier we investigated the influence of textures on collective excitations in superfluid He-3. For arbitrary textures we have obtained the quadratic form of the hydrodynamic action functional, which determined the collective mode spectrum. Using this quadratic form we have calculated the whole collective mode spectrum for B-phase of helium-3 closed to boundary. The texture splits the real squashing, squashing and pair breaking-modes and leads to appearance of gaps in goldstone-mode spectrum.

Using the path integration technique, developed by Brusov and Popov earlier for investigation of collective properties of superfluid phases of He 3 we study the collective mode spectrum in polar phase of He 3. This phase has points and lines of gap nodes. We derived equations, describing all 18 coll

Different types of porous materials as surface coatings on samples (RhFe wire) are investigated at Hells and HeIIp in respect to their influences on the heat transfer. Experimental results of measurements on samples with and without coatings are presented. Wires covered with capillary filter plates
