The third chapter contains my research work, which mainly focuses on Planar Photonic Bandgap. The idea of how to miniaturize Planar Photonic Bandgap by using spiral structures is proposed. Finally, by using ununiform method, the bandwidth, which is decreased due to miniaturization, are enlarged obviously.

首先介绍了平面光子晶体在微带线结构中的几种应用；然后阐述了我们在平面光子晶体小型化设计中所做的一些工作，包括仿真方案的选择，设计方案的制定与比较，以及与传统结构的比较；最后介绍了采用渐变周期结构对小型化所带来的带宽减少问题所做的改善工作。

Both the proteins components contained in haemolymph, fat body and ovary and the kenetics of the vitellogenin in haemolymph and ovary were analyzed by SDS—polyacrylamid electrophoresis, Ouchterlony plate tests and Rocket—immuno—electrophoresis. The results showed that the vitellogenesis initiated in adult stage and the Vg in haemolymph was detected firstly at 48h after eclosion. The titer of Vg in haemolymph raised rapidly in following 3 days and almost at the same time the vitellin appeared in oocytes. It was taken about 4—7 days after eclosion for the first eggs to grow up to the matured statics and to be laid out.

SDS-PAGE，双向免疫扩散和RIE分析粘虫生殖周期中血淋巴，脂肪体和卵巢中蛋白质谱带以及Vg滴度的变化，结果表明，Vg发生始于成虫期，Vg在血淋巴中的首现时间在羽化的24小时以后，以后连续三天血淋巴中的Vg滴度迅速上升，与此同时，开始沉积卵黄，卵母细胞逐渐发育长大，到成熟排出体外时大约历时4-7天。
