5,6-Benzoquinaldine and 8-hydroxyquinaldine have been used as organic bases for the quantitative precipitation of silica as silicomolybdic salts of the bases under suitable conditions of acidity. The salts, being stable and non-hygroscopic, may be directly weighed after drying at 110–150° C or alternatively may be ignited at 550° C with free access of air to silicomolybdic anhydride. 相似文献

A proper incorporation of boundary effects, in terms of a surface term contribution to the one-loop soliton mass in (1+1)-dimensional supersymmetric theories, is shown to resolve the problem of renormalizability in the soliton sector, which otherwise arises in a finite space calculation of the soliton mass using a modified version of a set of boundary conditions proposed by Rouhani. The saturation of the Witten-Olive bound for such boundary conditions follows immediately. 相似文献

The supercurrent anomalies of the supercurrent μ of the supersymmetric Yang-Mills theory in Wess-Zumino gauge are computed using the supersymmetric dimensional regulator of Siegel. It is shown that and in agreement with an earlier calculation based on the Adler-Rosenberg method. The problem of exhibiting the chiral anomaly and a regulator for local supersymmetry suggests that the interpretation of dimensional reduction in component language is incomplete. 相似文献

The nonlinear distribution function of Allis, generalised to include the transverse electromagnetic waves in a plasma, is
used to set up the coupled wave equations for the longitudinal and the transverse modes. These are solved, keeping terms up
to the cubic order of nonlinearity, by using the method of multiple scales. The equations of wave modulation are derived,
which are solved to discuss the nature of the modulational instability and solitary wave propagation. It is found that the
solutions so obtained satisfy conditions which are very similar to the well known Lighthill criterion for stability, appropriately
modified due to the coupling of the two modes. The role of the average constant current due to any flow of the resonant and
trapped electrons in determining the stability, is also discussed. 相似文献
