基于RA准则的多用户OFDM自适应资源分配算法改进，速率自适应算法的分析，对于自适应算法研究的朋友很有帮助(RA-based criteria for adaptive multi-user OFDM resource allocation algorithm for improved analysis of the rate adaptive algorithm, adaptive algorithm for friends helpful)

关于TCR+FC型SVC的研究文献，这篇文章考查了晶闸管控制的并联补偿器的理论基础。不平衡负荷补偿和电压稳定的条件是建立在对称分量的应用上的。适用于前馈控制（电脑的）的数学关系是根据。这里对前馈和反馈的实用方法进行了讨论。(This paper examines the theoretical foundations of thyristorcontrolled shunt compensation. Conditions for unbalanced load compensation and voltage stabilization are established with the use of symmetrical components. Mathematical relationships applicable to feedforward (computational) type controls are derived. Practical approaches to both feedforward and feedback type controls are discussed.)
