最后，本文以实例分析讨论了横向剪切变形、开孔大小、线布载荷位置和几何参数对临界载荷的影响。
Finally, some examples are given to show the effect of shearing deformation, the hole size, the position of linear load and the geometrical parameter on the critical load.
本发明的有益效果：刮种过程中没有剪切作用，消除了伤种问题，降低了吸种孔堵塞的可能性。
The seed pushing device has the advantages of avoiding damages to seeds due to no shearing effect generated in a seed pushing process and reducing the possibility of blockage of the seed suction hole.
结果表明：随着多孔二氧化硅孔面积的增加，层合玻璃中无机玻璃/聚氨酯界面的剪切强度先迅速增大后缓慢降低；
The results indicate that with the increasing of pore area, the shear strength between inorganic glass and polyurethane in laminated glass first increases rapidly, and then decreases slowly.
