The authors have developed a vertical lumbar traction apparatus and treated 180 patients with prolapse of lumbar intervertebral disc with the apparatus. The effective rate is 83.3% and the ineffective rate is 16.7%. 笔者应用自行研制的立式腰椎牵引治疗机,对180例以腰椎间盘突出症为主的腰部疾患患者进行牵引治疗,有效率达83.3%,无效率为16.7%。
By using the theoretical study results, the modification of the developed vertical disc brush wheel type seeding apparatus was curried up and the results were proved well. 应用理论研究成果对研制的垂直圆盘刷种轮式排种器的参数进行了改进,收到了较好效果。
The general differential equations of vertical vibration of disc cutter suitable for breaking hard rock, soft rock and soil were respectively established by adopting displacement constraint and force constraint as the lower boundary condition. 本文分别采用位移约束及力约束作为滚刀的下端边界条件,建立了适用于滚刀滚压硬、软岩和土壤的一般垂直振动微分方程,并对实验用滚刀进行了算例分析。
The study is divided into two parts: 1 Effects of different posterior internal fixation on vertical compression stiffness of lumbar vertebra and pressure distribution of intervertebral disc cartilage end-plate. First, pre-experiments are done with calf specimens, and skills in experiment are exercised. 整个研究从下面两个部分进行:第一部分:不同脊柱后路内固定对腰椎压缩刚度及椎间盘软骨终板压力分布的影响。首先利用小牛标本作预实验,熟悉实验操作及技巧。
At present, the vertical bearing capacity of the disc pile has been increasingly recognized by people, and much research about it has been done in the world. 目前,支盘桩的的竖向承载力已逐渐被人们认可,国内外对此的研究也比较多,而支盘桩的水平承载力研究依然处于相对落后的状态。
