Chirped fibre Bragg gratings (CFBGs) are required to be concatenated to compensate the fibre dispersion in the dense wavelength-division multiplexing (DWDM) systems. When the channel spacing is small, the performance of CFBGs is degraded, which restricts the usage of fibre gratings. The origin of the interactions between the gratings is analysed and methods of suppressing the interactions are also proposed.

不同施氮时期对小麦籽粒品质性状空间分布的影响及调控
为了明确小麦籽粒不同部位品质性状的分布特征,探讨氮肥运筹对籽粒各层品质性状的影响,于2009-2011年在江苏省徐州农科院进行试验,叶面喷氮试验选用四个中强筋小麦品种：矮抗58、09-82、济麦22和徐麦30；不同叶龄期追氮试验选用强筋小麦品种徐麦7086,研究了花后叶面喷施氮肥和不同叶龄期追施氮肥(春2叶、春4叶、春5叶、孕穗期和开花期)对小麦籽粒品质性状空间分布特征的影响。主要研究结果如下：1
