Effects of spectral linewidth of ultrashort pulses on the spa-tiotemporal distribution of diffraction fields被引量：1: 《Chinese Science Bulletin》2001年第11期901-904,共4页Jingzhou Xu Li Wang Guozhen Yang; the National NaturalScience Foundation of China (Grant No. 39890390) and the State Key Basic Research and Development Program (Grant No. G1998010102).; The spatiotemporal characteristics of electromagnetic pulses with ultrabroad spectral bandwidth in the far field are analyzed by using classical scalar diffraction theory. The effects of the ratio of the frequency wid...; 关键词：PULSE PROPAGATION DIFFRACTION ultrabroad frequency BANDWIDTH THZ radiation.

ON ERDS'S PROBLEM OF BANDWIDTH OF GRAPH ADDING EDGE: 《Chinese Science Bulletin》1990年第17期1492-1493,共2页王建方姚兵郭锡伯; G+e denotes the graph obtained from the graph G by adding the edge e, the comple- ment graph of G, B(G) the bandwidth of G. In 1971, Erds asked whether B(G+e)≤B(G)+1 for any graph G and any edge e.In this letter, the...; 关键词：asked LETTER adding BANDWIDTH 酥子幼少
