The new three-dimensional k·p model for the electronic structure of A-15 compounds gives satisfactory results for the magnetic susceptibility; shear modulus; tetragonal strain at the transition temperature Tm; and the magnetic field effect on Tm and shear mode sound velocity. 相似文献

Laser Stark measurements have been made on the 02000000 and 03100110 vibrational transitions of 16O12C32S, 16O12C34S, and 18O12C32S, and on the 03100110 transition of 16O13C32S, using a CO2 laser. In addition to providing dipole moment information for excited vibrational states, these measurements give vibrational band centers accurate to several megahertz. To aid in optical pumping experiments, several near coincidences between CO2 laser transitions and OCS absorption lines are discussed. Electric-field-allowed ΔJ = 0 transitions are observed for the 2ν2 band of 16O12C32S and 16O12C34S, as well as ΔJ = 2 transitions for the same band of 18O12C32S. 相似文献

Various ellipsometric analyses have been derived to characterize the optical properties of a single-layer or a double-layer surface film overlaid on a substrate material. The general numerical technique is independent of the method (or methods) used in the series of ellipsometric measurements which provide the raw data. The convergence to unambiguously determined values of the unknown parameters is systematically carried out in the numerical search procedure. Selected examples are presented to illustrate the validity of various analyses and the possible usage of these analyses to optimize the experimental conditions and measurement methods. 相似文献

Most problems in management involve multiple goals and two approaches to solving managerial problems have been suggested: optimizing and satisficing. The first covers methods of trade-offs, optimizing in tandem, conversion of goals into constraints and goal programming. The second mainly centres on norm setting and on interval programming. It is argued that cost-benefit analysis essentially belongs to the first group and that, contrary to some suggestions, the differences between the industrial and public sectors (as far as O.R. is concerned) are not related to differences between the optimizing and satisficing philosophies. 相似文献
