Présentation de l'éditeur
Volume XIX. July, igo. Number .THE PHYSICAL REVIEW. SOME NEW RECTIFYING EFFECTS IN CONDUCTING GASES. By p. G. Nutting. THE passage of electricity from a metal to a gas or from a gas to a metal occurs in a manner not yet well understood. The present investigation was undertaken to determine what conditions of the metal or gas favor the transfer of electricity from one to the other and if possible to throw some light on the mechanism of surface condition. While the results here presented are crude, they bear directly on the theory of metal-gas conduction and the method, though very simple, is believed to be new. The work suggested itself during some spectroscopic work with Pliicker tubes. If we use a direct current in studying the electrode drop in potential, we are confronted by the great difficulty in keeping the condition of the surface, temperature, pressure, etc., constant and in reproducing these conditions in successive tests. But if we use an alternating current of a maximum voltage just a little above the maximum total drop in potential between electrodes, conditions cannot appreciably change between successive alternations and the excess of current in one direction may be taken as a rough measure of the relative surface conductivity at the two electrodes. It is hardly conceivable that there can be any rectifying effect due to the gas itself away from the electrodes, for this would require not only molecular or atomic dissymmetry but a fixed orientation of these particles.

Paperback. Etat : New. Print on Demand. This book investigates the mechanism of surface conditions on the electrical conductivity of gases. The author presents a simple method for determining the electrical conductivity of very dilute hydrochloric and nitric acid solutions. Light upon the absorption and electrical conductivity of fluorescent solutions is also examined. The book then outlines the distribution of temperature in an air liquefier of the single-circuit type, and concludes with a study of radiation pyrometry. Through original research and critical analysis of previous studies, the author demonstrates the importance of understanding surface conditions in order to accurately measure the electrical conductivity of gases and fluorescent solutions, contributing to our understanding of the fundamental principles governing these phenomena. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9781330626696_0
