Chemical Research in Chinese Universities 1997年第1期13卷 79-84页

作者： LANG Mei dong, ZHANG guo, feng Na , and CHEN Xin fang (Institute of Materials Science, Jilin University, Changchun 130023  Chemical Engineering Department, Dalian Institute of Light Industry, Dalian 116036)

Poly(ethylene oxide) containing azogroups(pre PEO) was prepared by reacting azoisobutyronitrile (AIBN) with poly( ethylene glycol ) (PEG). The molecular weight of pre PEO was depended on the reaction time, the ratio of PEG to AIBN and the molecular weight of PEG. Pre PEO decomposed in the presence of butylacrylate (BA) monomer to form poly ethylene oxide block butylacrylate copolymers(PEO b PBA). The molecular weights of PEO b PBA and the homopolymer of PBA were proportional to the ratio of BA to pre PEO. The purified block copolymers were charactherized using IR, 1H NMR and GPC.

在自动目标识别系统中,目标探测起着重要作用.文中利用美国陆军实验室提出的特征级融合方法,应用于相干激光雷达强度像中目标中心点位置的确定.即通过局部最大灰度特征、对比度特征、平均梯度值特征和局部变化特征,最终确定激光雷达目标中心位置.经实验仿真结果表明,相对形心跟踪器确定中心点,该方法不易受到环境的影响而且发现目标中心位置准确性更高,提高相干激光雷达发现目标的准确性.
