增加狭窄腰椎管的硬膜囊矢状径，②使凸入椎管内的肥厚黄韧带拉长受薄，减轻对硬膜囊和神经根的压迫，③增大椎间盘后缘高度。

The pelvic nerve of inferior hypogastric plexus originated from the most caudal root of the pelvic splanchnic nerve, running along the surface of the levator ani and passing laterally around the vagina and rectum to enter the sphincter musculature at the 5-o'clock and 7-o'clock positions. 7l.4% of specimens were found intrapelvic branches which were given by pudendal nerve. Before leaving the pudendal canal, pudendal nerve gave an intrapelvic branch that passed the levator ani and accompanied with pelvic nerve to innervate the sphincter when it approached the sphincter. The distance between these intrapelvic branches and the level of the bladder neck was about (12.6±1.6)mm.

结果：控尿神经是由下腹下丛和阴部神经盆内盆外分支组成，其中盆神经是下腹下丛远端盆内脏神经分支，沿肛提肌表面到达尿道5点和7点位。71.4%的标本中发现阴部神经存在盆内分支，此分支自阴部管内的阴部神经主干穿肛提肌进入盆内，大约在接近尿道括约肌时汇入盆神经共同进入尿道括约肌，其进入尿道的位置距离膀胱颈平面(12.6±1.6)mm。

According to the experiment results,the author analyses the combustion propagation mechanism of detonator delay composition and believes that the combustion in the lead tube is impulsive combustion,which is the key factor of influencing the delay precision of the detonator;secondarily,the effect of the igniting power terminal is also very obvious.

本文实验测试了硼系延期药和硅系延期药燃烧传播过程，根据实验结果分析了延期药燃烧传播机理，认为延期药在铅管内的燃烧是脉动燃烧，是影响雷管延期精度的主要因素，其次点火药头的影响作用也十分明显。
