1. Based on theoretical analysis of stepped bending vibration boring bars, the frequency equation of a stepped bending vibration boring bar with circular and square sections is established. 通过对阶梯式弯曲振动镗刀杆的理论分析，推导出了圆形截面和矩形截面组合的阶梯弯曲振动镗刀杆的频率方程，并对阶梯弯曲振动镗刀杆进行了试验研究。
2. Boring force wave and boring specific power are measured separately through the test that shaft bit and ball hammer impact(bore) the rock directly. 通过钎杆和球锤直接冲击（凿入）岩石的试验，测定出凿入力波形及凿碎比功。
3. The boring, cutting and insertingbamboopin in top ofanthuriumstemare able to accelerate its side bud bourgeoning, and the boring is best in effect. 作者通过试验表明，对盆栽红掌植株茎上部刺眼、摘心、插竹签都可促进其侧芽萌发，其中以刺眼效果最好；
4. Anchorage drill pipe is widely used in boring of rock and hill anchorage and other worksite with hole boring on straight line. 锚固类钻杆广泛应用在岩石钻孔，山体锚固等直线成孔的工作场所。
5. For improving the boring stability a boring bar with intelligence capacity has been designed, which contains an electrorheological(ER) fluid and is with on-line controllable dynamics. 为保证镗削加工切削稳定性，基于电流变材料设计一种智能型镗杆。
