本文介绍了连铸结晶器的振动装置的发展，并以各铰链点位置坐标为优化变量，针对板簧受力和整体结构，给出相应的约束条件，对四连杆振动装置和半板簧振动装置进行了优化分析。

Reducing gear drives cam rotate to top half-turn and link gear of upper gate move, top disc opens and discharges. Spring device makes disc close and replace with displacement of cam. When cam rotates to bottom half-turn link, gear of sub-layer gate moves, below disc opens and discharges. The disc closes little by little with the displacement of cam. These two actions maintain a closed state of either disc on the pipe. So it can discharges and lock air at the same time.?

减速装置带动凸轮旋转至上半圈时，上层阀门的连杆机构互动，阀板逐渐打开卸灰，随着凸轮的旋转，弹簧机构使阀板逐渐关闭复位；凸轮旋转至下半圈时，下层阀门的连杆机构互动，阀板逐渐打开卸灰，随着凸轮的旋转又使阀板逐渐关闭，这样两个动作使管道上阀板始终有一个是关闭状态，因而，可使卸灰与锁气同时达到目的。

Many types of steering linkage have been made to connect between the steering knuckles of the front wheels and the pitman arm of the steering gear.

很多类型的转向连杆装置都是用来连接前轮转向节和转向器的转向摇臂的。

Thirdly , a conclusion has been settled down in this dissertation: Because the shaft inertial force vector do not pass the center of the rotating center of the system, there is a moment generated by the shaft inertial force and the counterforce of the cylinder wall to counterbalance the pressure which is imposed by the piston, so, it is important to consider the tortile effect on the flexible supporting component of the balancing machine dedicated to motorcycle crank set, which is originated by the moment.

第三：得到了一个结论：在设计制作曲柄连杆机构动平衡测试装置时，必须考虑这一受力情况，即连杆在作平面运动时，其自身的惯性力与汽缸对活塞的反作用力二者之间形成的力偶将会对弹性支承元件产生扭矩的作用。

Generally we used traditional analogism and the improvising method to design them. In this paper, the finite element analysis method is applied. Firstly, the static analysis of the device is carried out and the reaction forces at the joints are calculated.

本文基于有限元分析理论，首先研究装载机的工作装置的静力分析问题，根据装载机工作装置受力最大时铲斗所受的外力，以及装载机工作装置的位置分析，求得装载机工作装置中摇臂和连杆零件各铰接点处所受的力。

The pseudo-static test which subjects to horizontal load on the A-type autoclaved aerated concrete block wall was adopted. Reinforced concrete beams were set up at the upper and lower ends of the test block, and the four-bar linkage device was provided to ensure that the top of the wall was only in translatory motion, not in rotation at the level force. Hydraulic synchronous loading device was adopted to simulate the vertical load which was produced by the wall of the housing interlayer.

对A类蒸压加气混凝土砌块墙体采用水平荷载作用下的伪静力试验，试件的上下两端设置了钢筋混凝土梁，通过四连杆装置保证墙体顶部在水平力作用下只有平动而无转动，并采用同步液压加载装置模拟房屋层间墙体作用的竖向荷载。

The specific method is: first host of the brake rod to remove the trailer brakes to adjust the various parts, when the trailer brakes until the wheels with the ground so far appeared prints hysteresis drag, and then host the brake rod lever arm with pedal connections, and adjust the brake connecting rod connecting the host length, until the brake unit, all wheels have friction with the ground traces of the adjustment shall be qualified.

具体方法是：先把主机的制动连杆摘掉，对挂车制动装置的各个部位进行调整，直至刹车时挂车的车轮与地面出现拖滞印痕为止，然后再把主机的制动连杆与踏板的杠杆臂连接好，调整主机制动连杆的连接长度，直到机组刹车时，所有的车轮与地面有摩擦痕迹，即为调整合格。

This movement is produced by gearing and linkage between the steering wheel in front of the driver and the steering knuckle.

这一运动是由装在驾驶员前面的转向盘与转向节之间的转向器和连杆装置来共同完成的。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
