The Coupled resonator model and the distribution of the electric Field on the axisin the singly periodic cavity chain and biperiodic chain with full-cavity terminationsare analysed by Helmholtz Equation using the symmetry properties of the structure.It is another method to check coupled circuit theory. The results given in this paper forthe singly periodic cavity chain with full- cavity terminations was verified by a 600MHZ linac model of IHEP. 本文从场的对称特性来解析整腔结束的单周期和双周期谐振腔链的振荡模式,并给出它们的场分布,作为对用等效电路理论研究谐振腔链的振荡模式和场分布的另一校核方法.其中整腔结束的单周期谐振腔链的振荡模式、色散关系以及它们的场分布,经高能所600兆赫模型腔链实验证明结论正确。 In this paper, the stability of Periodic resonators is analysed.It is found that them- rod N- Period resonator has m stable zones and in each stable zone there are N- 1 sinsularpoints in which the resonators is critical stable and sensitive to the deviations.The thermostable conditions of Periodic resonators is also discussed. 详细分析了一般周期性谐振腔的稳定性，发现对一每周期合ｍ根激光棒的Ｎ周期谐振腔，共存在ｍ个稳定区，并在每一稳定区内存在（Ｎ—１）个奇异点，在这些奇异点处，谐振腔处于介稳状态，对失周期性很敏感；另外，还讨论了周期性谐振腔的热稳条件问题。 This paper presents a new group of quasi-resonant converters:constant frequency cyclic quasi-resonant converters (CF-CQRC), which is yielded by the replacement of the switch cell in PWM converters with a novel constant frequency cyclic resonant switch(CF-CRS).Their simple operating procedures ease the analysis and design.

This paper presents a new group of quasi-resonant converters:constant frequency cyclic quasi-resonant converters (CF-CQRC), which is yielded by the replacement of the switch cell in PWM converters with a novel constant frequency cyclic resonant switch(CF-CRS).Their simple operating procedures ease the analysis and design. They show better performance of loading and control range than the conventional QRC. As compared with the cyclic quasi-resonant converters (CQRC), CF-CQRC operate at constant frequency which benefits the optimization of the filter elements and the design of control circuits. 用一种新的恒频周期谐振开关代替脉宽调制（ＰＷＭ）开关变换器中的开关单元可得到一类新的准谐振变换器：恒频工作的周期准谐振变换器（Ｃｏｎｓｔａｎｔ－ＦｒｅｑｕｅｎｃｙＣｙｃｌｉｃＱｕａｓｉ－ＲｅｓｏｎａｎｔＣｏｎｖｅｒｔｅｒｓ，简称为ＣＦ－ＣＱＲＣ）。该类变换器工作过程简单，分析设计容易，负载特性良好，并且克服了传统ＱＲＣ可控范围极有限的缺点（因频率可调范围大的ＶＣＯ难以设计）。与调频工作的周期准谐振变换器（ＣＱＲＣ）相比，新的ＣＦ－ＣＱＲＣ因恒频工作而具有更好的控制性能，使优化设计成为可能。
