Atom, molecule or radical can be excited to a specific intermediate state by absorbing m laser photons, then the parent ion can be produced by absorption of another n laser photons. The ion yield can be increased drastically due to resonant absorption, comparing with the ion yield in non-resonant absorption. This multiphoton process is usully called Resonance Enhanced Multiphoton Ionization. REMPI technique plays an important role in detecting the high electronic excited states of atoms, molecules and radicals.

原子、分子、离子或自由基在同时吸收m个光子从下态共振跃迁到中间态后再吸收n个光子使其电离的过程中,下态和中间态的多光子共振吸收使得产生的离子信号强度比相应的非共振多光子电离得到的离子信号强度有很大的增强,该过程称为共振增强多光子电离REMPI。

The definition and stability criterion of resonant operating points in a CPT system have been described. A Poincarémapping model has been built up and its Jacobian matrix has been derived with the implicit function derivative rule and chain rule. Then the stability of the fixed points can be determined according to the eigenvalues of the the Jacobian matrix. It has been used to study an example push-pull CPT system with three resonant operating points.

Due to the high reliability, high stability and low EMI criterions in auxiliary power supply systems, the half-bridge LLC resonant converter is selected for the front-end converter, the AC bus architecture and full-wave rectifier are as well utilized. The turns-ratio between the AC bus and load converter is 1:1. The effect of beads which are used in the load converters to the resonant circuit is analyzed.

根据辅助电源高可靠性、高稳定性、低电磁干扰、良好的高频隔离的要求,通过对不同拓扑类型的分析比较,选择半桥LLC谐振变换器作为前级变换器,交流母线和零式全波整流结构作为后级变换器,在母线和后级变换器的连接上采用1∶1的隔离变压器连接。

Some circuits use resonant, quasi-resonant, and/or multi-resonant techniques. However, voltage or current stresses in these converters are higher and require the devices of higher VA rating. Some circuits use passive snubbers or active clamp techniques. However these converters become more complicate. Phase-shift ZVS technique has been used in bidirectional DC/DC converters since it can realize ZVS for all switches without auxiliary switches.

谐振、准谐振或多谐振技术方案,变换器的电压电流应力较高,变频控制增加了滤波器设计的难度;能量缓冲吸收电路或有源钳位电路方案,由于需要增加多个额外辅助元件,增加了变换器的复杂性;全桥相移技术方案,由于主电路无需增加额外元件,只需利用相移控制,即可实现软开关,因此引起关注。

In order to support a preselected resonant mode, a series of concentric rings (18) is formed in the blocking layer (16, 19), surrounding the resonant cavity (2) so as to provide a Bragg structure which reflects light from the cavity with a phase characteristic that supports the preselected transverse resonant mode.

The analytical expresses of scattering field are obtained based on the boundary condition of a sheath helix model. The effects of the pitch angle and the electrical size of the helix on the resonant behavior are also investigated. It is shown that the resonant behavior of the forward/back scattering far field only depends on the pitch electrical size and the radial electrical size, and that the turn of the helix has no effect on the resonant behavior.
