Methods : One hundred and twelve patients ( 142 teeth ) were selected and divided into two groups . They were randomly applied by submucous infiltration anesthesia or nerve block anesthesia by using articaine or procaine in extraction of teeth .

方法：112例患者的142 颗 患 牙随机分为两组，分别进行粘膜下浸润麻醉和神经 阻滞麻醉，对其麻醉注射时及拔牙时疼痛程度、麻醉持续时间进行分析。

The contact force between the steel pile and pressing block teeth in underwater skirt pile gripper was simulated with ANSYS software based on augmented Lagrange method . The contact force and extruding deformation of pressing block tooth under the practical condition were obtained and compared with theoretical results .

基于扩展的拉格朗日算法，使用ANSYS软件对钢桩和夹桩器压块 齿的接触问题进行了数值模拟受力分析，获得压 块齿实际工况下的接触压力及其挤压变形等结果。
