第五章对现有超短波单工电台的天线转换开关、锁相环、调频等电路进行了改造以使得改造后的电台配接TMS32010、8031组成的硬件系统成为数字时分同频双工电台。

Benzoyl chloride was treated with potassium selenocyanate in dichioromethane by using polyethylene glycal-400 as the solid-liquid phase transfer catalyst to yield the corresponding benzoyl isoselenocyanate. This intermediate did not need to be isolated and directly reacted with arylamines, affording the N-benzoyl-N'-arylselenoureas 2a~2p. These compounds were characterized by IR, 1H NMR spectra and elemental analysis and the single crystal structure of 2k has been confirmed by X-ray crystallographic analysis.

The proposed method is performed in abc phase-coordination,so it can be applied to transposition or untransposition lines(single-or double-cir cuit lines)and the non-diagonalizable situation of produce matrix ZY .

本文方法在abc相分量上进行计算，所以适用于均匀换位或不换位的单回线、双回线和线路传播常数矩阵ZY不能对角化的情况。

Further picosecond PL studies on dendronized PFs show that the fluorene-based emission in dilute solution follows a single exponential decay, whereas those in thin film decayed in a multi-phase manner and the lifetime prolongs with the generation of dendronization. These observations are discussed in terms of dispersive transport happening between adjacent chains in film. The dispersive relaxation can be controlled by site isolation of bulky dendrons. Our results prove that dendronization is highly effective in controlling the inter-chain interactions of fluorene-based polymers.

不同代数树枝化聚芴的时间分辨荧光动力学研究结果表明，溶液状态下的发光为单指数衰减行为，而薄膜状态下的发光为多指数衰减行为，且其发光寿命随树枝化代数增加而增长，表明树枝化基团抑制了邻近的聚芴分子之间能量传递所致的激发态能量耗散。
