Ecause of stronger resonance enhancement to incident pump beam given by the Bragg microcavity, the enhancement effect of the phase conjugation wave produced by Bragg microcavity was more outstanding than that caused by naked third order NLM.

ragg微腔中的三阶NLM产生的相位共轭波相对于该介质裸露时产生的相位共轭波具有明显增强，这主要是Bragg微腔对入射泵浦光产生了较大的共轭增强作用。

Therefore, the covering-domain method can be adopted to calculate the radiated sound field from the complex-shaped multilayer elastic/nonelastic closed cavity.

从而可应用覆盖域的思想和方法计算复杂形状双层弹性/粘弹性封闭腔体或内层填有吸声材料的双层封闭腔体在外力作用下的辐射声场。

Methods We adopted four methods that single cpidural block anesthesia or narcotics analgesies were injected into subarachnoid space and epidural space or single narcotics was injected into subarachnoid space (group C fentanly 25μg;group D fentanly 20μg) to study analgesia birth for 130 nullipara women. The analgesia efficacy, side effect, birth time md mode,postpartum haemorrhage and the condition of the fetus and the newborn were compared.
