Natural frequencies and damping coefficients were determined from the fomulae: W = C (g/r )1/2 6 = C i.84ir /(R )1/2 1 0 2 0 for spheres, and /2 1/2 = CjL(jAg/r.)l 6 = C21,841M /(R0) for cones, where r 0 is the radius of the free surface and r0 is the radius of spheres. The dependence of C I and C 2 in spheres, on relative depth is shcwn in Figs. 14 and 15- For cones the variation of C 1 and C 2 with inclination angle a is shown in Figs. 16 and 17~ The cone formulae were obtained for fluid depths h > r 0 and for amplitudes of up Card 4/6 290 64 S/179/61/000/004/CC7/019 Experimental investi-ation .... r,195/E335 to 0.01 r0 at the wall.

Until the sand reaches the crack it has to travel a considerable distance along the vertical tube. Therefore, for selecting a rational technology of the process of breal:ing up a stratum it is important to know the hydro-mechanical picture of motion of a mixture of liquid with sand, both along the crack and in the verti~zal tube. Special experiments were carried out to verify Cardl/2 whether available relations are applicable for such SOV/ JZ4-58-11-~ eyt2 nd On the Movement of a Mixture of Liquid with San in the a__ in the Crack During Hydraulic Fracture of an Oil Bearing Stratum coarsely disperse suspensions as mixtures of liquid and sand; the experimental set-up is shown diagrammatically in the sketch, Fig.l. The basic liquid used in the experiments was glycerine and for obtaining various viscosities the 151yeerine was diluted with water; furthermore, sulphite-alcohol distillery refuse was used, which is frequently applied in the oil industry as a liquid for breaking up strata. As sand, quartz sand with the fractions 0.6-0.85 mm was used and in some of the experiments sand of other fractions was used. Curves calculated on the basis of the relations expressed by Eqs.(2.1), (2.8) and (2.11) are plotted in the graph, Fig.6; in the same graph the values determined in the here described experiments are also plotted.

The DDA-100!,' sprinkler (designed by the VTITIGiT4) had given -~,cd tervice on the "'Pakhta-Aral" sovkhoz but the Session criticized the Tashirmash Plant for producing defective and poor-quality sprtnk- lers and other meliorative macninery. To help exiend the use of watering equipment Dn cottcn farms intensi- fied research on such equipment is required. The Uzbek- skaya akademiya.sellskokhozyay~Btvennykh nauk (Uzbek Academy of Agricultural Scienc-9s) should encourage and equip the Uzbekskaya dozhd.?val'naya stantsiya (Tjzbek Sprinkling Station) and organize a chain of sup- porting centers to introduce watering equipment in the Golodnaya 9tep' and Fhorezm region.

The calculation of the field of such a system reduces to the Dirichlet problem for the Poisson equation,&U - q(Xi, Y) in a rectangl under the condition that U = 1 on the boundary of the rectangle, and q'(x, y) = 0 everywhere inside the rectangle, with the exception of the electrodes, on which U(x) y) = u(x) y) is specified. Computation formulas are given to determine the potential field and an algorithm is presented for the computer calculiLtion of the coefficients of the system of algebraic equations. It is indicated that by using the Adams-Stoermer extrapolation formula, and by assuming the potential field that results ftom the calculation, it is possible to determine the flight -trajectory of the electrons from the system of ordinary differential equations of -the form dly L Ox I du (X.
