In this paper we describe the isomorphism classes of finite-dimensional complex Leibniz algebras whose quotient algebra with respect to the ideal generated by squares is isomorphic to the direct sum of three-dimensional simple Lie algebra sl2 and a three-dimensional solvable ideal. We choose a basis of the isomorphism classes’ representatives and give explicit multiplication tables. 相似文献

To understand and reveal the basic physical factors providing the possibility of scaling of a discharged singlet oxygen generator (DSOG) in an oxygen-iodine laser, the production, and transport kinetics of metastable O2(a 1δg) and O2(b 1σ g + ) molecules, as well as O(3 P) atoms, were investigated in Ar:O2 and He:O2 gas flows excited by a 13.56-MHz discharge in a wide range of pressures (4–40 Torr) and oxygen percentages. It is shown that the densities and transport kinetics of O2(a 1δg), O2(b 1σ g + ), and O(3 P) appear similar for oxygen mixtures with argon and helium in the same conditions independent of discharge mode. Compared to pure O2, the dilution of oxygen with an inert gas allows higher energy inputs per an oxygen molecule to achieved, especially under conditions of the homogeneous discharge mode (α-mode), which gives a higher efficiency of O2(a 1δg) excitation in Ar:O2 and He:O2 mixtures. But the maximum attainable yield of singlet oxygen in Ar:O2 and He:O2 at fixed partial O2 pressure is found to be comparable with the O2(a 1δg) yield in pure oxygen at the same pressure. The reason for this is the increased three-body deactivation of O2(a 1δg) by atomic oxygen in the mixtures because of the greater total pressure. The estimation of the rate constant of O2(a 1δg) three-body quenching by O(3 P) in Ar:O2 and He:O2 mixtures as (1.5 ± 0.5) × 10?32 cm6/s was carried out from the analysis of transport kinetics of singlet and atomic oxygen in the discharge afterglow at high pressures exceeding ~10 Torr. A similar analysis for the lower pressures has revealed that losses both of metastable O2(a 1δg) and O2(b 1σ g + ) molecules, and of O(3 P) atoms on the surface of the discharge tube, are determined by the density of each of the components. The obtained loss probabilities of O2(a 1δg), O2(b 1σ g + ), and O(3 P) on the silica surface show that the surface loss probabilities of all the species can increase noticeably under the discharge exposure. Thus, the key parameters determining the maximal O2(a 1δg) yield in the DSOG are a homogeneous volumetric mode of the discharge, energy input per oxygen molecule in this mode, and a low rate of O2(a 1δg) quenching. Just three-body quenching of O2(a 1δg) by O(3 P) limits the singlet oxygen yield with increasing pressure. The fast removal of atomic oxygen both in discharge and in the earlier afterglow could provide DSOG scaling with pressure. 相似文献

The study evaluates compatibility of stabilizers with dye doped liquid crystal (LC) scaffolds that are used in electronically dimmable materials. The photodegradation of the materials was investigated and suitable stabilizers were evaluated to slow the degradation process. Various types of benzotriazole-based stabilizers were evaluated for stabilizing the liquid crystals. Based on spin trapping experiments, radicals generated upon UV exposure is likely responsible for the degradation of the system. The radical generation is competitively inhibited by the addition of stabilizers. 相似文献
