Das theoretische Auflösungsvermögen des Elektronenmikroskops

R. Rebsch1938-01-01Annalen der Physik

Abstract Der unvermeidbare Öffnungsfehler der Elektronenlinsen bewirkt, daß das theoretisch erreichbare Auflösungsvermögen des Elektronenmikroskops außer von der Wellenlänge auch von der Brennweite der Objektivlinse abhängt. Da dieser Brennweite aus Herstellungsgründen eine untere Grenze gesetzt ist, liegt die mit rau…

On the Theory of Space Charge Between Parallel Plane Electrodes

C. E. Fay、A. L. Samuel、W. Shockley1938-01-01Bell System Technical Journal

The problem of the potential distribution, current, and electron transit time resulting from the perpendicular injection of electrons into the space between parallel planes is considered. The electrons are assumed to be injected uniformly with velocities corresponding to the potential of the plane through which they a…

THE THEORY OF PHOTOELASTICITY *

Hans Mueller1938-01-01Journal of the American Ceramic Society

A bstract The photoelastic birefringence of solids is caused by the superposition of two effects. An elastic deformation changes the arrangement of the atoms. If the deformation is a simple strain, this effect produces negative birefringence which increases with increasing refractive index of the solid. The second eff…

THE STRUCTURAL DESIGN OF FLEXIBLE PIPE CULVERTS

M G Spangler、George E. Shafer1938-01-01Highway Research Board Proceedings

THE STRUCTURAL PERFORMANCE OF FLEXIBLE PIPE CULVERTS WAS STUDIED WITH THE OBJECTIVE OF DEVELOPING A RATIONAL THEORY OF DESIGN. LABORATORY TEST RESULTS JUSTIFIED THAT EVEN THOUGH THE DEFLECTIONS AND ACCOMPANYING CHANGES IN RADIUS OF CURVATURE WERE RELATIVELY LARGE, THE ELASTIC THEORY WA APPLICABLE TO CORRUGATED METAL P…
