The device comprises retaining means for keeping the lid (2, 3) in place in a sealing manner during treatment, and the retaining means comprise a bounding frame (10) that is circumferentially closed, with two interconnected end pieces (11, 12) situated at a distance from each other, which end pieces in a closed position can be slid over the pressure vessel (1) and thereby retain the end faces of the pressure vessel (1) in the axial direction.

所述装置包括用于在处理期间以密封方式将盖子(2、3)保持在适当的位置中的保持装置，并且所述保持装置包括沿圆周方向密封的围绕框架(10)，具有两个布置在相隔一定距离的位置处的互连端部件(11、12)，其中所述端部件在关闭位置中可滑到压力容器(1)上，从而沿轴向方向保持压力容器(1)的端面。

Over the years, when we discussed thixotropism, than indirect cause of thixoforming, the simplest method is: earthquake activity ink system is in the outside world rhythmic Sesmic into a gel, its rhythm vibrations can be gently tapping regular circumrotation or tilting agitation, and so on, that is, if you are not without effect could cause-and-ink, when the formation of condensation solids reach 1%-2%, and particle not òao radiofrequent symmetry form a gel is entirely the result of the particle moves towards the arrangement.

多年来，在我们辩论触变性时，不常遗漏了不直接的触变来因，最简单的辨别办法是：震凝性的火不朱编制是在边界有节拍的波动下变不败凝胶，其节拍波动可以是不沉不沉敲打，有法规的圆周活动或摆式搅动等，即若无边界功用不离不克不及造不败火不朱形不败固结，当那不流体含量到达1％－2％把握，而且粒子不呈不不差称性时，其形不败凝胶合座是粒子走向摆列的甘休。

Using two-flank-staining method, inspect the tooth flanks of the driven bevel gear, 3 to 4 equispaced spots along the circumference, at each spot apply color to 2 to 3 teeth, the correct meshing print requirements are: print width in the direction of face width not less than 50% to 60% of the facewidth , and that in the direction of tooth depth not less than 40% to 50% of the tooth depth.

用两面着色法，在从动锥齿轮的齿面检查，沿圆周均布3-4处，每处2-3齿涂色，正确啮合印迹要求为：在齿宽方向的印痕宽度不小于齿宽的50%---60%，在齿高方向的印痕宽度不小于齿高的40%---50%。

The cylinder of 280mm in circumference applicable for decorative seaming on the collar and the sleeve of children's wear and for cylindrical seaming on knitted wear as well.

机筒的圆周长只有280毫米，特别适用于儿童服饰的领口，袖口等的装饰缝，且对针织品的筒状缝纫机有适当的辅助功能。

The results indicate: diversion shell can transform the kinetic energy of fluid into pressure energy well, and eliminate the circumferential component of fluid; the inlet incidence angle of vaned diffuser increases at the condition of O.8Q, and it results in flow separation very likely and the hydraulic loss increases; it is nearly non-impact inflow at the condition of 1.2Q, and the velocity distribution is uniform at the inlet of vaned diffuser and flow separation dose not appear.

结果表明：导流壳能很好地将叶轮中流出的流体的动能转化为压能，并消除速度的圆周分量；在0.8Q工况下，空间导叶的进口冲角增大，容易在空间导叶背面产生流动分离，造成水力损失增加；在1.2Q工况下，空间导叶的进口接近无冲击入流，在进口处流速分布较均匀，其内部未发生流动分离现象。

Image reconstruction from the projections of fan-beam: The CT equipment is broadly adopted on the world that its detectors are arranged on the concentric circle at same angle interval. This equipment rebates the complex machinery movements like parallel-beam geometry, makes the sampling time shorter, that is rebating the whole CT testing time.

扇形束图象重建：将探测器等角间隔排列于同心圆周上采集射线投影数据，然后进行图象重建的CT装置是目前世界上广为使用的，它减少了平行射束采样方式的繁杂的机械运动，可有效地缩短数据采集时间，也就是减少了CT检测的总的花费时间。

Suppose you are running a car at a constant speed with a constant curvature, if you then keep the steering wheel in the same position and increase the car speed gradually, then if the car wants to run on a circle with a smaller radius the car is said to be oversteering, if it remains on the same radius it is neutral and if the car goes to a wider circle it is understeering (for that speed and curvature!).

假设你以固定的速度沿固定曲率的圆周驾驶车辆，然后你保持方向盘角度不变，逐渐增加车辆的速度，此时车辆行使的半径如果变小，称为转向过度（在这个特定的速度和曲率下！）。这个测试还有不同的做法。

Meanwhile, the line divides into two cores----"symbol"and"culture", namely human is the living thing employing symbol to create culture; Through the function of symbol to interpret human nature, he gests his original view of humanity---"human is animal of symbol"; Through cultural pattern to interpret human, he gets"culture----cycle of humanity".

而这条主线又围绕着两个核心概念展开：一个是&符号&，另一个是&文化&。即人是运用符号去创造文化的生命物。从符号功能去诠释人的本质，得出了他独特的人性观：&人是符号的动物&。从文化形式去诠释人，他得出了&文化——人性的圆周&。

When cutting tool roaled of spindle's hole by manipulator or other ways,the pull nail behind of knife hilts is sent to ahead of tension bar of spindle. When receives the clamps signal, the pressure oil is passed over the oil cylinder left cavity of the spindle rear part, the piston to the right migration ,tension bar also to right migration by small dish shape spring function, the stell ball of ahead circumference of the tension bar shrink the distribution diameter by spindle's cone hole's force, holds on the knife hilts and pull nail colsely.

当刀具由机械手或用其他方法装到主轴孔后，其刀柄后部的拉钉便被送到主轴内拉杆的前端，当接到夹紧信号时，将压力油通入主轴尾部的油缸左腔，活塞向右移动，拉杆在碟形弹簧的作用下也向右移动，其前端圆周上的钢球在主轴锥孔的逼迫下收缩分布直径，将刀柄拉钉紧紧拉住。
