This paper studied the bifurcation and chaos phenomenon in a multi-parallel-connected current-mode controlled boost DC-DC
converter system with the use of nonlinear mapping bifurcation theory of two dimensions, and the changing rules of the bifurcation
charts with the increase of the control parallels and control parameters were concluded. The method of discrete mapping modeling
was utilized to construct the difference equations of the system operating in continuous conduction mode (CCM). Analyses and
computer emulations were made.

Graduate education in optical fiber communication technology in China is described. A detailed account of the experience accumulated by Shanghai Jiao Tong University is provided as a typical example. There are three areas of graduate programs in this university: guided-wave fiber optics, optical-fiber transmission systems, and optical-fiber local area networks (LAN). The textbooks used in one of the courses conducted by the author are examined. The subjects of some of the M.Sc and Ph.D dissertations are listed. Graduate students who have received degrees are encouraged to submit papers to Chinese and foreign technical journals for publication. Appendices listing Chinese universities which offer such graduate education is included, along with a list of language reference books used in China 相似文献

In this paper, the near-field vector components were used to combine the FEM method and the uniform-geometrical theory of
diffraction (UTD) method for analyzing phased array antenna mounted on an airborne platform. First, HFSS, a set of software
based on finite element method (FEM), was utilized to find the near-field vector components of the phased array antennas,
and then these vector components were used as the source of the UTD method to get the disturbed radiation pattern. Numerical
results show that the hybrid of the two methods not only extends the use of the UTD program, but also effectively solves this
type of challenging problems.
