Through image analysis captured from video,effects of contact materials,seed charge height and inclined plane obliquity on all motion parameters of the collision were detected and analyzed.

利用高速摄影仪和高分辨率摄像头分别从竖直和水平两个方向对水稻种子与斜面发生碰撞后的运动轨迹进行了在线跟踪,通过摄像图片的再现,检测与分析了接触面材料、投种高度和斜面倾角对种子碰撞后各运动参数的影响。

On the basis of detailed study on Hoek-Brown criterion,the definition of intact rock pieces for layered rock mass is evolved and an important parameter in Hoek-Brown criterion,the uniaxial compressive strength of intact rock pieces\' is proposed to be used for characterizing the variation of slates strength with schistosity orientation.

基于对Hoek-Brown经验破坏准则的深入研究,通过对层状岩体完整岩石试件定义的改进,提出用Hoek-Brown准则的一个很重要的参数,即完整岩石试件的单轴抗压强度σci来表征层状岩体强度随层面倾角的变化规律以及应用Hoek-Brown准则来分析层状岩体强度的方法。
