BY 1965 the metallurgical output shal'. reach the following figures; 65 to 70 million tons of cast iron; 86 to 91 million tons of steel; 65 to 70 million tons of rol- led metal; 150 to 160 million tons of commercial iron ore. The Seven-Year Plan includes the construction of in4u3trial units with an output of 24 to 30 million tons of -ast iron; 28 to 36 million tons of steel and 23 to 29 million . ns of rolled motal.

ABSTRACT: The absorption of ultrasonic waves in viscous liquids has been investigated very little. Bazhulin (4) has estab- lished a second power relation between absorption and frequ- ency in glycerine, in the 5 - 20 Mc/s range. No agreement can be found in literature as to the abso;ute value of absor- ption. Bazhulin (1) has found that at t = 21 G the experi- mentally obtained values differ by 3011o with the Stokes fieuxe: Litovich (5) has found them differing by the factor of 2. Absorption in castor oil and other vegetable oils has been measured by Bazhulin and I. Mikhaylov (4), (6). In the present article, the author presents the iesults of his measurement of absorption of ultrasonic waves, using the impulse method, for three different experimental conditions: 0.26 - 2.5 Me/s, 4.0 - 18 Mels and 15 - 30 Mels. The wund velocity was measured with an ultrasonic interferometer, the Card J/ 2 viscosity - with an Ostwald visaximeter and density with a picrometer.

ABST-11ACT: A series of photographs of light spectra in liquids, subjected to various sound intensities and at different dis- tances between the quartz and the light beam intersecting the ultrasonic field, were taken in an endeavour to establish the law, governing the asymmetry of the diffraction spectrum when large amplitude ultrasonic waves are present in the liquid. The descri-Dtion of the measuring arrangement is given. It is thought th~at the observed asymmetry is the result of distortion of the ultrasonic waveform, due to the presence of shock-waves. The existence of the L-.tter in liquids has been experimentally established by Zarembo et al. (4) and subsequently confirmed by Fox and Wallace (5), (6). Following calculations of Bigu- ard (7), the authors have satisfied for the conditions of the shock-waves initiation. They also mention that within the &rd 1/2 range of the sound intensities used, the ultra-sound velocity remained constant (within the experimental error of approx.

Ultrasonic Waves in Structur- ul'trazvukow,,~_h voln bol'shoy rastvorakh) PERIODICAL: Akusticheskiy Zhurnai, l')57, Vol.III, Nr 3, pp.239-242 (USSR) ABSTRACT: The propagation of ultrasonic waves of large amplitude in liquids is of major interest. It was shown in (Refs.1 and 2) that the coefficient of absorption of ultrasonic waves de- pends on the intensity of ultrasound. So far this effect has only been observed in some pure liquids. The present authors have studied the absorption of ultrasonic waves of large amplitude in solutions having structural viscosity. It might be expected that in this case at large intensities a break up in the structure of the solution would occur. This would necessarily have an effect on the coefficient of ab- sorption as a function of intensity of ultrasound. Thus, a study of the absor~,tion of ultrasonic waves of finite ampli- tude may lead to information on the interactions between molecules of structurated solutions.

The present authors reported earlier (Ref 1) that on transmission of a light beam through a liquid layer, In which ultrasonic vibrations of large amplitude were excited, a diffractional image with asymmetrical distribution of the diffractional waxima was observed. It veas also reported that with increase of distance between the sound source and the light beam, this asymnstry increases. Fig 1 repeats in qualitative form the results obtained in L~ef I by giving the distribution of intensity in diffractional maxima for thLree distances between the sound source and light beam k7, 25, 65 cm respectively) and for various values of the sound intensity . The curves in Fig 1 are envelopes of microphotograms of maxima aith the highest intensities, as shown in Fig 1, 1. All curves have, in general, two maxim which are resolved only at sufficieutly high acoustic sound intensities. Fig 2 shows Card 1/3 photographs of diffractional ijaages corresponding to curves of Fig I. Diffraction of Light on Ultrasonic Waves of !Arge Apiplitude 46-4-2-10/20 Those photographs and curves illustrate diffraction of light on ultrasound of 573 Icc/s frequency (0.26 cm wavelength) and up to 15 W/CM2 intensity at a depth of 2 cm in distilled water. The present paper deals with the Interpretation of the diffractional image asymmetry. The authors suggest that the cause of this asymmetry lies in the distortion of the sinusoidal form of sound wave at large acoustic intensities. The sinusoidal wave is assumed to be distorted into saw-tooth form at high ultrasound intensities - Galculations assuming saw-toothed wave are in gond qualitative agreement with the experimental data on the distribution of light in diffractional images obtained earlier by the authors. These calculations took into account only the phase modulation of light, excluding the amplitude modulation. This does not inean, however, that the latter is absent and in general modulation should be regarded as mixed, i.e. amplitude and phase wodulation present together. The authors thank S.L. Rytov for his advice.

Nozdrev at al. published a nwaber of papers on absorption of ultrasonic wavou in acetates and formates k?'ofs 1-3~- These papers confirmed the ~mown fact of the existence of relaxation in such liquids. They 41so found that, e.g. in ethyl acetate, two maxima are observed on the curve *LX = f kV) , where at Is the coof f icient of absorption, k is the acoustic wavelength and v is the ultrasound frequency. These maxima "were found in the frequency region 3-30 Mc/s and the corresponding relaxation times vvere calculated to be 0.98 x 10-6 and 2.65 x 10-8soc at 200C. The present author disputes the relaxational nature of both those maxima. He points out that the relaxational theory shows that to rosolve two relaxational maxima In measurements whose precision is of the order of 5-10~., these relaxation times must diffsr by a factor of not less than 10. Thu s) if in ethyl acetate there are two maxima In the region 3-30 kcls, they are Card 1/3 not relaxational maxima. This was pointed out by the proLiont uutior 46-4-2-15/20 on the ProbLow of Absorption of Ultrasonic *ffav96 in 3thyl Acetate and his co-worders at various conferences in 1956-7. Oince aftor discussions at those confacences the probleia of the nature of these Liaxima was btili an open question the author carried out some furthdr weasurements of ul-,rasound absorption in eth.11 acetate. These ware made using a pulse LnetYod in the temperature region -40% to 42003. A piezo-quartz wed6e was used as the ultrasonic source. The method used was carefully checked on a number of known liquids such as m-xylol, benzene and others , and good agree~,ent was obtained between the results reported earlier by other authors and those obtained using the wed7a method. The autrior found ti~at in the ro6ion 5-20 Mc/s the experimental points for ethyl acetate at all tomperaturns lie on a curve of the form G~/V2 = A/11 + (-PlVr) 2] + b, whore Vr is the relaxation frequency. This curve is given in a figure on p. 199 and the experimental points obtained by the present author are shown us circles, while those of V.F. Ilozdrev and A.-. Sultanov (Rof 1) are shown as crosses. All th-jee results wore obtained at 200G. 7he values of constants in the equation for the curve shown in the fi6ure are A = 70 x 10-17 and B a 32 x 10-17. The relaxation time is Card 2/3 On the Problem of Absorption of Ultrasonic Waves in Ethyl Acetate 46-4-2-15/20 calculated to be 1.25 x 10-880C. The author's curve agrees weli with that of Karpovich.6iven by Boyer and Jacob kief 4) and with the majority of exparimental data given in Rof 4. The figure on p. 199 shows that there is a corisidarable difference between the results of Nozdrev and Sultanov and tt,ose of the present author particularly at frequencies below 20 Mc/s. The present author regards Nozdrev and Sultanov's results, as well as those of Beyer and Smith (Ref 5)1 to be in error. In the present author's opinion only one relaxational region exists in othyl acetate. It is suggested, however, that at frequencies greater than 100 kc/s there should exist a second relaxational region in ethyl acetate. rhoreare one firura and five rof3roncos, throe of wilch are Sovitit and two American.
