角板

The expressions of dihedral angle and cutting angle of the intersecting groove are deduced by way of space analytical geometry.

利用空间解析几何原理推导了多管、板相贯坡口的两面角和实际切割角的表达式，建立了切割多管、板相贯坡口的数学模型。

We have in-house rolling, forging and machining capability to manufacture all types of fishplates including plain, joggled, angle, and combination fishplate to various drawings for various rails.

我们有内部的轧辊，锻造和机床加工这样的技术，有能力去生产所有类型的鱼尾板包括普通鱼尾板，啮合型鱼尾板，角形鱼尾板和组合型鱼尾板根据各种各样的图纸为各种各样的铁路。

Are covered by a theca, or armour, composed of many textured plates that form one horn in the front

壳由许多具花纹的板片组成，这些纹板组成一个前角和通常两个后角

Ceratium species are covered by a theca, or armour, composed of many textured plates that form one horn in the front and usually two in the back;

The main components of the lathe are the headstock and tailstock at the oppoaite ends of a bed,and a tool-post between them which holds the cutting tool.the tool-post stands on a cross-side which enblesit to move sidewards across the saddle or carriage as well as along it,depending on the kind of job it is doing.the ordinary centre lathe can accommodat only one tool at at time on tool-post,but a turret lathe is capable of holding five or more tools on the revolving tueeet.

刀架位于一个纵面板上，小拖板使刀架能够根据加工操作的不同作纵向移动；同时又随大拖板作横向移动。普通顶尖车床只能在刀架上夹持一件刃具，但六角车床可以在其旋转的六角刀架上夹持五件或更多的刃具。车床的床身必须很牢固结实以避免在受力的时候弯曲和变形。请提问的同学最好参观一下工厂的金属切削/机加工车间。那里有车床，还有其他种类的金属切削机床。

Methods:keep supraspinous ligament,interspinous ligament ,thoracolumbar and the periosteum of lamina.The supraspinous ligament and interspinous ligament was cut off below affected spinal canal.The lamina was cut off longitudinally with a chisel along the outside of lamina,detach ligament flavum bilaterally,and reverse upward lamina and the compound structure of back to open spinal canal.

将部分腰背筋膜、棘上韧带、棘间韧带及椎板上骨膜保留，于病变节段下一椎间隙切断棘上棘间韧带，用骨刀（骨刀宽面与矢状面成角10~15度）在上下关节内侧2mm处自下而上并保持骨刀宽面进入椎板深度与椎板厚度相一致切断两侧椎板，牵开椎板及棘上棘间韧带，常规进行椎管减压，椎板及棘上棘间韧带回植。

The results show that the ultimate stability bearing load by nonlinear analysis is close to the test load, they only have 10% deviation. For steel bridge towers, the correlation of the panels in the section of rectangle with chamfers is more obvious than that in the section of rectangle. If the four angles of the rectangle section were cut off, a panel with the smaller ratio of width to thickness forms, which can supply effective constraint to other weak panels with the larger ratio of width to thickness.

结果表明：第2类稳定计算得到的失稳极限荷载与实测荷载较为接近，两者相差10%；带切角矩形截面钢桥塔较矩形截面钢桥塔板件间的相关作用更加明显，对矩形截面钢桥塔进行切角，形成宽厚比较小的壁板，可以对宽厚比较大的弱板提供有效约束。

BW-WJ universal angular corrugated compensator is made up of structures such as one (or more the two namely composite universal angular type) bellows, forelock, axis, hinge plate, universal loop and standing board etc. It can absorb angular displacement in any plane and bear the pressure or thrust of the bellows. When large compens-ation is required, two or more compensator can be assembled and utilized in series. Besides, the product can also be pre-pressed, pulled or reversed when installed.

BW-WJ型万向角向型波纹补偿器由一个（或二个及以上，即复式万向角向型）波纹管、销、轴、铰链板、万向环和立板等结构件组成，能吸收任意一平面内的角位移并能承受波纹管压力推力的膨胀节，当需要大补偿量时，可采用两个或以上组合分段串联使用，并对产品预压缩、拉伸或扭转安装。
