It is found that the sensor tip with a 90 ° conical tip has the maximum optical modulation depth. 理论和实验的结果表明,顶角处于90°左右的光纤尖具有最大的光调制深度。
And the truncated conical tip projectile with large length-diameter ratio is suitable for Penetration. 高长径比的截锥型相切尖拱弹丸有利于穿甲。
To provide a theoretical basis for the conical stylus cone angle selection. ( 2) Analysis of the stylus tip radius and the stylus static pressure causing timber roughness parameter measurement error, calculation of the roughness measurement error value caused by the different tip radius. 分析触针针尖圆角半径和触针静压力引起的木材粗糙度测量误差,计算不同针尖半径造成的粗糙度测量误差值。
