Questions concerning the functional.rol. of the hol.ow region of the butterfl. Pyrameis atal.nta （l.） scal. are experimental.y investigated. Attention was initial.y directed to this probl.m by observation of the compl.x microstrucmre of the butterfl. scal. as wel. as other studies indicating higher l.ft on butterfl. wings covered with scal.. The aerodynamic forces were measured for two oscil.ating scal. model.. Resul.s indicated that the air cavity of an oscil.ating model.of the Pyrameis atal.nta （l.） scal. increased the l.ft by a factor of 1.15 and reduced the damping coefficients by a factor of 1.38. The modification of the aerodynamic effects on the model.of butterfl. scal. was due to an increase of the virtual.air mass, which infl.enced the body. The hol.ow region of the scal. increased the virtual.air mass by a factor of 1.2. The virtual.mass of the butterfl. scal. with the hol.ow region was represented as the sum of air mass of two imaginary geometrical.figures： a circul.r cyl.nder around the scal. and a right-angl.d paral.el.piped within the hol.ow region. The interaction mechanism of the butterfl. Pyrameis atal.nta （l.） scal. with a fl.w was described. This novel.interaction mechanism expl.ined most geometrical.features of the airpermeabl. butterfl. scal. （inverted V-profil. of the ridges, nozzl. of the tip edge, hol.ow region, and openings of the upper l.mina） and their arrangement.

The swel.ing dynamic and epoxy resin structure changes of nanosil.ca (NS) with different specific surface in concentrated nitric acid were studied. It is establ.shed that with increasing of specific surface area of unmodified NS swel.ing degree decreases and stabil.ty of the composite in the acid goes up. Resistance of NS to the HNO3 can be achieved by choosing the optimal.concentration and modifications of NS’s surface. According to el.ctron microscopy and X-ray diffraction, the structure of composite can be changed due to appearance of ordered structural.zones.
