By means of test bed designed previously, several practical experiments are carried out to study IEEE802.1P for real-time be-havior of switched industrial Ethernet. Compared the experimental results with theoretical analysis, we can find their deficiency and perfect them. The experiments have shown the potential problems due to interference between priority levels. The experiments would direct the theoretical analysis and practical improvement in industrial Ethernet for process control.

作者：郭本瑜 shanghai university of science and technology

In this paper, we consider the discrete approximation of abstract operator equation. We proposethe definition of generalized stability of discrete problem, which is equivalent to usual stabilityas long as the operator is linear. Under some conditions, such stability gives the unique existenceof approximate solution and the convergence. In this paper, we deal with the relation between suchstability and the stability of practical computation and the uniform boundness of approximatesolution. We also give a new critique of optical approximation. Finally, we take Burger’s equationas an example to show how to use the idea here.

作者：黄宏嘉 shanghai university of science and technology

It is rediscovered that some early works on conventional waveguides, including several published papers by the author, are applicable to optical fiber and film waveguides. This paper shows that the coupling coefficients for ideal modes, for local modes and for superlocal modes are all related by similar matrices in the sense of Lowey, and as far as discrete modes are concerned, the 'equivalence' expressions derived by Marcuse are special cases of our general results. Physical arguments will illustrate the reasonableness, under certain restrictions, of extending the applicability of the said relations to eases which also include a continutun of modes.

Proceeding from two-dimensional equation of motion of circular piezoelectric ceramic disks,withthe variables separated we can obtain a set of equations which depends only on the axial variable *** solving them with adjoint method according to the boundary conditions,the thickness vibrationalfrequency spectrum obtained is relative to the radial expansive ***,from thefundamental frequency of thickness vibrations we can calculate the spectrum of radial expansive *** the result of calculations by this method,we can see that the radial and the axial vibrationspectra of circular piezoelectric disks are not only mutually influenced,but as well as dependent ontheir dielectric,piezoelectic,and elastic constants,that is to say'coupling'relations exist.
