_基于射线跟踪模型的3.5 GHz无线传播特性研究
说明： 3.5 GHz 是 5G 网络部署的重要频段，本文结合射线跟踪模型，对 3.5 GHz 的无线传播特性进行了研究，并于 1.8 GHz 进行了对比，提出 5G 网络初期部署的建议(3.5GHz is an important frequency band for 5g network deployment. In this paper, the radio propagation characteristics of 3.5GHz are studied in combination with ray tracing model, and compared with 1.8GHz. Suggestions for initial deployment of 5g network are proposed)

ABAQUS技巧积累
abaqus 使用技巧-Inp文件中单元类型改变时，一定要注意，划分网格的时候是否，选用了一种望各类型，比如4变形和3变形的区别，如果用注意将所有的单元类型都做相应的修改。这说明单元类型由2个因素决定，1网格形状，2计算任务.(Abaqus tips-When changing the unit type in the Inp file, be sure to pay attention to whether or not to select a type, such as 4 deformation and 3 deformation, if you use the attention, all the unit types should be modified accordingly. This shows that the unit type is determined by two factors, 1 grid shape, 2 calculation tasks.)
