The united states tries its best to push the eastward expansion of nato in an attempt to maintain its hegemonic position and the unilateralization of the pattern of international relations 美国为维持其霸主地位和促进世界格局的单极化,竭力推动北约东扩。
In the development course of informal employment in china , there are such problems as dynamic instability , uni - polarization , sub - standard operational mechanism and forms in labor relations , and low level of union organization 中国非正规就业发展过程中存在着劳动关系动态入稳定、劳动关系单极化、劳动关系运行机制和形式不规范、工会组织化程度低等问题。
Modem international system is in progress of complicated changes , in which peace and development are the obvious features of globalization and the whole international setup presents the trend of compound development of both unipolarization and multipolarization 摘要当代国际关系处于复杂的变化进程中,其中和平、发展与全球化特征比较明显,整个国际格局表现为单极化与多极化的复合发展趋势。
Because of the full target texture and the acute speckle of the microwave - imaging machine , especially for the single frequency , single look and single polarization sar images , it is very difficult to extract image characteristics in the image pixel level Sar图像地物分类技术的困难性主要源于微波成像的特殊机理和严重的相干斑干扰,使得基于图像象素层的特征提取非常困难。对单视单极化sar图像而言,这个问题更为突出。
Theoretical analyze and computer simulation prove that the side lobe canceller system using polarization radar can depress jammer while not damaging the signal , the overall performance is better than that of the system using polarization radar only in the auxiliary antenna 理论分析和仿真实验表明使用全极化雷达的旁瓣对消系统,可以在抑制干扰的同时尽量不损失目标信号,系统整体性能优于主天线为单极化时系统的性能。
