An optical cross connection network which adopts coarse wavelength division multiplexing (CWDM) and data packet is introduced. It can be used to realize communication between multi-CPU and multi-MEM in parallel computing system. It provides an effective way to upgrade the capability of parallel computer by combining optical wavelength division multiplexing (WDM) and data packet switching technology. CWDM used in network construction, optical cross connection (OXC) based on optical switch arrays, and data packet format used in network construction were analyzed. We have also done the optimizing analysis of the number of optical switches needed in different scales of network in this paper. The architecture of the optical interconnection for 8 wavelength channels and 128 bits parallel transmission has been researched. Finally, a parallel transmission system with 4 nodes, 8 channels per node, has been designed.

为解释天王星窄环的长期存在现象 ,研究了天王星ε环在其两颗牧羊犬卫星作用下的动力演化 .采用平面椭圆型限制性三体问题模型 ,其中三体分别为天王星、卫星及环粒子 .基于描述环粒子演化的常微分方程 ,得到了一个映射系统 .对该映射系统的数值研究表明 ,只有那些初始位于卫星共振有序平动区的环颗粒才能被卫星控制 ,从而得以长期存在 .而有序平动区的大小主要取决于卫星的质量和其运动轨道的偏心率 .对于ε环的
