1) waveguide with small diameter
小孔径波导
2) Waveguide aperture coupling
波导小孔耦合
5) oriented diameter
引导孔孔径
1.
Oriented diameter is a important factor that affects the connect strength of wood and wood-based panel,and by testing WPC screw-holding and its L-type structure,this paper educes the optimization of oriented diameter.
而引导孔孔径是影响木材和人造板材螺钉连接强度的重要因素,本文通过对塑木复合材料的握钉力和L型构件结构强度的测试,得出塑木构件螺钉连接强度的最佳引导孔孔径。
6) small hole and shallow blasting
小孔径浅孔
1.
For the reason of small amount of detonating powder, the small hole and shallow blasting brings about small vibration and impact to the side slope, favouring to the stability and safety of the side slope and imposing slight influence on the surface of foundation rock.
小孔径浅孔爆破的起爆药量小 ,爆破对周边的振动与冲击较小 ,有利于边坡的稳定与安全 ,对建基面的爆破影响很小 ,且容易控制超、欠开挖量 ,保证开挖精度 ,在永久船闸二期工程的高直立边坡的成形开挖、底部保护层开挖中得到很好的运用。
