结论：以牙槽孔至颧下嵴起始部的弧长和弦长为标准弯制注射针头，采用口内注射法进行上牙槽后神经阻滞麻醉，成功率为98％。
Conclusion: We use L as arch length and H as chord length to bend syringe needle that is used to posterior superior alveolar nerve block anesthesia by intraoral injection. The success rate is 98%.
针对国内尚无有关蜂窝构件的规范或标准可以执行的实际情况，进行了蜂窝梁腹板在纯弯状态下的稳定问题研究。
As there is no criterion or standard about castellated member at home, study of the web stability of castellated beams under pure bending condition is carried out.
