1) third order resonance
三阶共振
1.

根据国际放射疗法的现状和发展,为了进一步提升国内的肿瘤放射疗法,研究设计了1台由两个完全相同的超周期组成的治癌专用离子同步加速器,包括LATTICE、多圈注入系统、RF加速及三阶共振慢引出系统。
2) nonresonant third order nonlinearity
非共振三阶非线性
1.
The experimental results for the nonresonant third order nonlinearity of the polymer films doped with acceptor donor azobenzene derivatives are reported.
研究了施受体型偶氮苯衍生物掺杂聚甲基丙烯酸甲酯（ＰＭＭＡ）薄膜的非共振三阶非线性，比较分子结构与材料的三阶非线性关系，得知越大的三阶非线性对应分子内越强的给受电子能力，在苯环上接上一个侧链基团可以增加分子的偶极矩，即增加了材料的三阶非线性。
3) second-order resonance
二阶共振
1.
