. 7. .: 7 Emissions rates of motor transport serving civil aviation airports at its tests on stand with running drums under European riding cycle are investi gated. Influence of hydrocarbon fuel type, flammable mixture inflammation method and automobile internal combustion engine on levels of formation of carcinogen and nitrogen oxides in exhaust gases is analyzed. Actual effec tiveness of measures used on reduction of certain pollutants emissions in at mospheric air is estimated. Following investigations directions are selected.

. 2. .: 8 Process of production powders by electropulse dispersing of conductive material. Results of investigations of size distribution of metal powders are shown. Investigated powders are steel and aluminum alloys. Particle size dis tribution of the energy input is plotted. Amounts of metal, which passed in the oxides and hydroxides is calculated. Phase composition of the powder is de termined. Minimum and maximum droplet sizes of dispersible material are de fined.
