The 3D elastic mechanics and finite-element structure analysis priniple were provided.The mechanics characteristics of the three-faced aluminous rotating mirror were analyzed,and the finite-element model was established.

给出了3维弹性力学空间问题基本方程和有限元结构强度分析原理，分析了三面体铝合金转镜空间结构强度的力学特征，建立了有限元模型，分析了其在轴孔与轴的3种配合关系下的应力分布。

In addition, the apparatus includes a motor for rotating the shaft to move the dressing stone held by the fixture along an arc centered on the longitudinal axis of the shaft into engagement with the cutting surfaces of the saw when the saw is rotating thereby to remove deposits from the cutting surfaces of the saw.

另外，该设备包括一个马达（18），在锯旋转时，该马达（18）使轴（14）旋转，并沿着一圆弧将由固定器（16）支撑的清理石移动到与锯的切割面接触的位置，上述圆弧以轴（14）的纵向轴线为中心，这样去除在锯切割面上的沉积物。

The faults include the fracture of saddle support mat , the breakdowns of saddle support bolt and pin spindle.

其中，鞍座底板断裂、鞍座连接螺栓和销轴断裂，通过断口形貌和受力分析，判断故障原因为典型的疲劳断裂；大小齿面磨损变形严重是齿轮硬度不足、齿面接触应力超过材料抗剪屈服极限及润滑方法不当造成。

The faults include the fracture of saddle support mat, the breakdowns of saddle support bolt and pin spindle. Based on the analysis on the fracture and surface, the fault causes are analyzed, for the conclusions of the normal fatigue fracture, as well as the deficient gear hardness, higher contact stress of tooth face than the yield limit under shear of material and improper lubrication method, which bring serious abrasion deformation of tooth face.

其中，鞍座底板断裂，鞍座连接螺栓和销轴断裂，通过断口形貌和受力分析，判断故障原因为典型的疲劳断裂；大小齿面磨损变形严重是齿轮硬度不足，齿面接触应力超过材料抗剪屈服极限及润滑方法不当造成。

When a plane wave illuminates the bottom of axicon with ring obstacle, a bottle beam is generated within the maximum non-diffractional distance, and the beam keeps non-diffractional Bessel beam in front and at the back of the Bottle beam.

平面波入射到带有环形障碍物的轴棱锥底面时，将在轴棱锥产生的最大无衍射距离内形成Bottle beam，而在Bottle beam的前后仍然保持无衍射贝塞尔光。
