_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)

usermat_CDM
说明： These composite materials generally exhibit brittle damage behavior. The anisotropy in the
material and different kinds of failure mechanisms make it difficult to accurately
characterize the behavior of composite materials. The present work aims to verify and
apply the Puck Failure Criteria using the commercially available finite element package
ANSYS by writing a user-material subroutine in FORTRAN. The model is implemented
with different post failure degradation schemes EWM/CSE.

说明： 对于非线性模型的跟踪预估问题，摒弃额对非线性函数进行线性化的做法，采用无迹变换处理均值和方差的非线性传递问题。(For the tracking and prediction problem of the nonlinear model, the linearization of the non-linear function is abandoned, and the traceless transformation is used to deal with the non-linear transfer of mean and variance.)
