为了调整输出电压及解决纹波问题，本文从能量守衡的角度设计串联谐振变换器的无源性状态反馈控制器。

The vibration velocity and sound radiation power curves of submerged cylindrical shell, has strong resonant characteristics. It can be described by resonance radiation formulas, which include superposition of inherence vibration modes, by using resonance radiation theory .

本文为验证共振辐射理论，对无限长和有限长圆柱壳体，首先计算了复共振频率并分析其固有振动特性，然后结合共振辐射理论讨论壳体振动和声辐射中各振动模式的贡献及其作用特性。

The experimental results show that under the present experimenal condition and in the cases without and with applied field, collisions are the reason leading to plane wave attenuation in the plasma. Plasma resonance absorption and upper hybrid resonant absorption mechanisms can not be found.

实验结果表明在非磁和本实验条件下，平面电磁波在等离子体中的衰减机理为碰撞吸收；在有磁和本实验条件下，平面电磁波在磁等离子体中的衰减机理同样为碰撞吸收，但是外加磁场的存在有限地改善了等离子体的吸波效应。

In addition, basing on the tight-binding model of the single electron and transfer matrix method, we study the charge transfer properties of Fibonacci sequence and discuss specially the dependent of electronic transmission on energy and the length of the sequence. We find some resonant peaks can survive in relatively longer Fibonacci sequences than random sequences, which also implies there are long-range correlations in Fibonacci sequences.

从Anderson紧束缚模型出发，采用传输矩阵方法研究了Fibonacci序列的电子输运特性，讨论了输运系数对能量及其序列长度的依赖关系，发现随着序列的长度增加，具有好的透射性的电子态数量有所减少，但相对于随机序列而言，共振能态可以在更长的序列中存在，进一步证明了Fibonacci序列中存在有较强的长程关联行为。
