10MW风力机叶片设计及其在随机风载荷下的响应分析
说明： 对大型风力机柔性叶片的设计方法及其在随机风载荷作用下的动态响应与载荷特性进行了研究。根据风力
机叶片空气动力学和结构设计理论，将柔性叶片离散为多个刚体，形成一个多体系统。根据多体动力学的建模方法
和叶片气动模型，考虑两者的相互作用，建立了柔性叶片的非线性耦合动力学方程并开发了相应的仿真程序。算例
分析了叶片在随机风载荷作用下的气弹载荷与随机振动响应，并对稳定风速和紊流风速下的响应结果作了对比分析(This paper presented a design method of the flexible blade and its dynamic response under random wind. The
flexible blade was discretized into multiple rigid bodies, and the multi-body system was established according to the theory
of aerodynamics and the structural design of the blade. The nonlinear aeroelastic coupling equations of a constrained
flexible blade are derived by the dynamics of multi-body system theory and the blade aerodynamics model, and the
simulation program was developed. The examples analyzed time-domain responses of the blade under stable and turbulent
wind speed, and the results were compared under these two kinds of wind speed.)

基于改进斜投影算子的极化域通信抗干扰技术
说明： 针对无线通信中的抗干扰和干扰抑制问题， 提出一种极化域通信抗干扰方法。在信号极化域利用斜投影极化滤波器， 以克服传统的频域抗干扰技术的缺点。通过对斜投影滤波器的特点进行研究， 在信号极化域设计多种干扰抑制和抗干扰技术， 包括优化极化发射信号、非线性矢量变换的增广斜投影滤波器以及接收信号的统计特性， 以改进斜投影滤波器的设计。(Aiming at the problem of anti-jamming and interference suppression in wireless communication, a method of anti-jamming in polarization domain is proposed. The oblique projection polarization filter is used in the signal polarization domain to overcome the shortcomings of the traditional frequency domain anti-jamming technology. By studying the characteristics of oblique projection filter, we design a variety of interference suppression and anti-interference technologies in signal polarization domain, including optimizing the statistical characteristics of polarized emission signal, augmented oblique projection filter based on non-linear vector transformation and received signal, in order to improve the design of oblique projection filter.)
