In this paper, an approximate expression for solving plane stress problem of orthotropic material is worked out based upon the procedures of Lecknitzky's work. For the purpose of applications, three simple examples are given, namely: (1) The bending of beam with circular hole, ( 2 ) circular hole in a plate under simple tension, ( 3 ) elliptic hole in an infinite plane with uniformly distributed p...
A β″ superlattice structure, with the ideal stoichiometrical formula AgAuZn2 and isoinorphous with that of Heusler alloys, has been found existing over a quite wide range of composition. It is, in fact, a superstructure of the β′ ordered structure. Its formation is accompanied by a sudden lattice contraction. The effect of gradual substitution of Ag by An on the atomic distribution has been stndie...
The effect of the anomalous magnetic moment of the nucleon on the value of the internal conversion coefficient is investigated.The parts played by the sealer and tho longitudinal photons in the process of the internal conversion are first discussed. The retarded interaction between the charged particles with anomalous magnetic moment is derived by the correspondence method. The results obtained is...
The triggering processes of some types of Schmitt circuit, have been investigated. Their switching speeds have been calculated and checked by experiments. The main results are as following:(l)The switching speed of an ordinary d. e. coupled Schmitt circuit is rather slow.(2)The use of break-away diode in the Schrnitt circuit) shortens the triggering process considerably.(8)With other conditions un...
This paper applies Kirkwood's method for calculating the configurational free energy E of a solid solution to a solid solution AB3 inhabiting a face-centred cubic lattice. In this method, the free energy F is expressed as a series in (kT)A-1, and our calculation goes as far as the coefficient of (kT)-4. If the order of the solid solution is denoted by S and the free energy on neglecting 0(kT)-n by...
The present paper continues an earlier investigation of the application of Meyer's theory of a gas mixture of two components to a solid solution AB inhabiting a lattice of the type AB by considering the A. atoms inhabiting the two different sublattices as forming two different components. It is proved that the different irreducible cluster integrals are linear functions (and hence the free energy ...
For the investigation of the reflection on transparent photocathodes we worked out a comparative method. By this method the absolute values of the common reflection coefficient of photocathode and glass envelope could be determined. Investigating a generally used type of photomultiplier (type RCA-5819) we found it to show a comparatively high reflection-50 per cent-in the maximum of sensitivity.
