The inner structure of the cast depends on the sand core and the eternal structure depends on the crystallizer ,it's a new production method including continuous casting and traditional casting .

连铸过程中铸件的内部形状由砂芯来实现，外部形状由结晶器来实现，是集传统铸造和连续铸造于一身的新方法。

Advantages of traditional crank press technology include low production cost and high speed production rate (30~1200 pieces per minute). Requirements of complicated die and limited product forming are the shortcomings. Additionally, the advantages of traditional hydro-forming technology are good product quality, complicated geometric shape and easy-made die. However the disadvantages are expensive cost of equipment, low production speed (less than 5 pieces per minute), and is not applicable to multi-station progressive process and high pressure working environment that has the concern of industrial safety.

传统曲轴冲压技术之优点是生产成本低廉及生产速度快(每分钟30~1200件)，缺点是模具复杂及成品形状成形性受限制；传统液压成形技术之优点是成品品质佳、几何形状容许大变形及模具简易，缺点是设备成本高、生产速度很慢(每分钟5件以下)、不适合多工程连续加工且具有高压之工安问题。

计算结果表明：采用解析法、有限元法计算出的轧件断面形状与现场实测出的轧件断面形状及板带凸度数值相近，这说明研究方法和模型的有效性。

Analysis is made on block effect to cutters of PDC bit with 3 factors: different top shape,cutter-distributing and wearing degree.By the interaction(radial range and altitude difference of each cutter) of three adjacent cutters,the cutter block is further analyzed with these factors,but wearing degree is simplified to be considered as the cutters vertical to the assembling plane.

中文摘要：对PDC钻头冠部形状及不同的布齿密度和切削齿在不同的磨损状态下对PDC钻头切削齿受力的影响进行了分析；用相邻的3个切削齿之间的关系（不同的切削齿与切削齿之间的径向距离和切削齿之间的高度差）来分析PDC钻头冠部形状和切削齿布齿密度对切削齿受力的影响，以及将切削齿的磨损状态简化成与切削齿在钻头上装配方向垂直的平面来分析切削齿磨损状态对切削齿受力的影响。

The results indicate that the interface curve in width varies along the flow direction. The flow rate ratio controls the coextrusion interface location. The interface deviate value increases with the increasing of the flow rate ratio. The difference viscosity of two layers polymer leads to the interface deflecting towards the lower viscosity side.

结果表明：宽度方向共挤出界面的形状和位置沿聚合物流动的方向不断变化；界面偏移量的大小随着流量差异的增加而增大；聚合物入口流量的变化是导致共挤出界面位置变化的决定性因素，流量比的变化对出口处界面形状的影响不大；两种聚合物粘度的不同会导致界面偏向粘度较低的熔体一侧。

Such facemasks have several designs. One type is affixed to the head with two ties, conforms to the face with the aid of a flexible adjustment for the nose bridge, and may be flat/pleated or duck-billed in shape. Another type of facemask is pre-molded, adheres to the head with a single elastic band, and has a flexible adjustment for the nose bridge. A third type is flat/pleated and affixes to the head with ear loops.

这类口罩有几种设计，其中一类靠两根带子固定在头部，在鼻梁处的调节可以弯曲，帮助口罩贴近脸部，形状是平面/平面打褶或鸭嘴状；另一类是模压成杯罩状的口罩，靠一根松紧带固定在头部，鼻梁处的调节也可以弯曲；第三类也是平面/平面打褶的形状，用耳带固定在头部。
