1·The relation between channel spacing and effect of XPM and FWM in DWDM system was analyzed, and a new solution for simulation of high speed and long haul DWDM system was derived.

本文分析了DWDM系统中xpm和FWM效应随信道间距变化的关系，并提出了大容量长距离DWDM系统仿真的解决方案。

2·A novel scheme is proposed, in which the aberrations in the off-axis holographic lenses used as demultiplexers are reduced to a low enough level for relatively small channel spacing.

本文提出了一种能够将解复用器用离轴全息透镜的像差减小到足以适用于相对较小的信道间隔的新方案。

3·The results also show that the channel capacity decreasinglyincreases with the antenna spacing and decreases with the coefficient K.

增大天线间距能够提高信道容量，但并不能一直提高信道容量。 K系数的增大，信道容量将会降低。

4·It is found that the blade Angle of the gas dispersion channel, the type of the lower impeller and the impeller spacing have significant influence on the macro-flow field in the tank.

研究发现：气体分散通道叶片角度、下层桨类型、桨叶间距对搅拌槽内宏观流动场有显著的影响。
