Magnetization Hysteresis Loop Tracer for Long Specimens of Extremely Small Cross Section

E. C. Crittenden、A. A. Hudimac、Robert I. Strough1951-12-01Review of Scientific Instruments

An instrument for measurement of the low frequency magnetic properties of thin layers is described. The difference signal from two opposed pick-up coils, one of which contains the sample, is amplified, integrated, and amplified again to cause the vertical deflection of a cathode-ray oscillograph to be proportional to…

The Diffusion of Copper in Cuprous Oxide

Walter J. Moore、B. Selikson1951-12-01The Journal of Chemical Physics

Cuprous oxide strips were prepared by the oxidation of copper at 1000°C. The diffusion of radiocopper in this material at 800 to 1050° gave a self-diffusion coefficient, D=0.0436 exp(−36100/RT). Virtually the same D is obtained from experiments in which radiocopper is plated on copper strips, and the distribution of a…

Statistical Thermodynamics of Rubber Elasticity

Frederick T. Wall、Paul J. Flory1951-12-01The Journal of Chemical Physics

Two principal differences between the theories of rubber elasticity advanced by James and Guth and by other authors are examined in the light of certain fundamental concepts. First the distribution functions for molecular chain lengths in vulcanized rubber networks are considered from the point of view of symmetry. As…

Cavitation Produced by Ultrasonics: Theoretical Conditions for the Onset of Cavitation

E.A. Neppiras、B E Noltingk1951-12-01Proceedings of the Physical Society Section B

An attempt is made to define theoretically the conditions for the appearance of cavitation in liquids subjected to alternating pressure changes. It is found that cavitation is restricted to a definite range of variations of the following parameters: (i) alternating pressure amplitude, (ii) frequency of the pressure wa…

Atomic Size Effect in the X-Ray Scattering by Alloys

Β. E. Warren、B. L. Averbach、B. W. Roberts1951-12-01Journal of Applied Physics

In a random solid solution, if the two atoms have appreciably different sizes, the nearest-neighbor distances and to a lesser extent the higher neighbor distances will be of three kinds, γAA, γAB, and γBB. The effect produces modulations in the diffuse intensity similar to those produced by short-range order. The size…
