At the end of the thesis , the basic physical characteristics of axially - emitted and radially - emitted electron beam are summed up , and the design methods of sws ( slow wave structure ) for high - efficiency beam - wave interaction according to the motion characteristics of e - beam are brought forward , these helpful discussions for design of microwave source are going to be validated by pic method 最后,本文在总结电子轴向、径向和角向运动基本规律的基础上,从电子运动的角度提出了高效率束波相互作用慢波结构的设计思路,为微波源的设计提供了一些有益的参考。
The motion characteristics of the suspended particles were obtained by statistical analysis , including vertical concentration distribution , mean velocity profile , turbulent intensity , velocity correlation , and the probability density distribution of the velocity fluctuations . attempt has also been made to interpret the turbulent characteristics in terms of particle properties and turbulence structure 对不同容重、不同粒径的颗粒在不同水流条件下的垂线浓度分布、平均速度和脉动强度分布、相关函数及脉动速度的概率密度分布等进行了全面系统的统计分析,得到的中文摘要主要成果如下:
