Wiping her eyes, Doa thought a moment." They go to heaven," she said, and then she smiled. 搽着眼角泪水的多阿想了一会儿说:"他们会升入天堂。"然后她又笑了。
In the near future, after the prototype program has been tested successfully, the crops Specific FREX will be developed in cooperation with DOA major crops soil-scientists. 不久的将来,一旦标准程序试用成功,就将与农业部从事主要作物研究的土壤学家共同开发作物专用“肥料推荐专家系统”软件。
This paper presents a method of DOA estimation performance and efficiency analysis for coherent signals by using spatial smoothing technical, it gives the simulation results of processing no coherent and coherent signal source 介绍了相干信号DOA空间平滑技术处理的方法及其效果分析,并给出了处理非相干和相干信号源的仿真结果,实验结果证明了空间平滑技术能够去相干性,达到了对相干信号源的方向进行识别的目的。
