The vibratory forming theory is introduced as follows. The vibration, which is obtained through shock excitation electric engines driving tow symmetric wobbler shafts, makes the compacted stuff generate vibratory shock.

其振动成型原理是通过激振电机驱动对称安装在振动台上的偏心块轴，产生激振力使振动台产生所需的振动，由于振动使被压实材料内产生振动冲击。

When the breaker works, the electric motor revolves passes the blet pulley or the shaft coupling, the drive shaft and the cricular cone department in the heart set comples moves cricles one fixedly does turnd on lathe suspends the movement, thus enable the cricular cone the wall to approach from time to time Leavel the solid attire to put on in the adjustment rolls over the white wall surface, causes the ore to be under the impact unceasingly in the cavity, the extrusion sum the curving functing but realize ore.

破碎机工作时，电动机的旋转通过皮带轮或联轴器、传动轴和圆锥部在偏心套的迫动下绕一固定作旋摆运动，从而使破碎圆锥的破碎壁时而靠近又时而离开固装在调整套上是轧白壁表面，使矿石在破碎腔内不断受到冲击，挤压和弯曲作用而实现矿石的破碎。

In this paper ,move ment pri nci ple of rocket i n direction pi pe was got by dy— namic si mulation ,and effect characteristic consideri ng contact stiffness ,detent force and nozzle thrust misalignment a— bout pitchi ng angle velocity was analysis .All the study set foundationfor further study of high—lowpressure launch sys— te m.

通 过发射仿真分析，获得了火箭弹在高低压发射系统中的内弹道变化规律，分析了火箭弹与定向器的接触刚度、耳轴扭转刚度、尾喷管推力偏心等因素对俯仰角速度的影响特性，所得结论为火箭武器高低压发射系统的进一步相关研究奠定了基础。

When an axle journal is at a certain position in a bearing, the pad tilting angle is related to initial eccentricity and clearance ratio, but unrelated to speed, viscosity, etc.

当轴颈在轴承中位置一定时，可倾瓦块摆角只与原始偏心和间隙比有关，与转速、粘度等无关

Optimum position of a bottom tuyere and amount of gas blowing in a combined blowing converter were determined by measurement on perfect mixing time of metal bath via water model experiments.

采用水力学模型试验，通过测定熔池均匀混合时间长短，确定复吹转炉底部供气元件最佳位置和供气量。结果是单支底部供气元件偏心布置在炉底耳轴方向0.4D位置，供气量在0.557～0.928m3／h的复吹熔池均匀混合时间最
