凹板

Solid carbide tungsten fishtail drill is suitable for pcb flexible foil clad laminate,used for target machine drilling,the features of pcb fishtail drill are thin and flexible plate,it's structure and cutting methods are different with normal pcb drill bits.its two main cutting edge is concave and formed 100degree angle,in order to distinguish with PCB drill,named fishtail drill.fishtail drill cuts beginning of circular drill.concave along the main cutting edge to cut,chip is just two much fine filament.cuttingis falling off naturally,in order to be processed without burrformation by pcb surface.

整体硬质合金鱼尾钻适合印制电路板行业加工挠性覆箔板，为打靶机钻孔用。鱼尾钻所加工的印制电路板特性是薄板、带柔性、这样就决定了它的结构和切削方式与一般PCB钻不一样，它的两主切削刃是内凹的，两主切削刃形成100度的夹角，为了与PCB钻区别，就叫它鱼尾名。鱼尾钻切削时从我圆处钻尖开始，沿着内凹的主切削刃切削，切屑只是两条极细丝状切削，整个切削自然剥落，从而被加工印制板表面平整无毛刺。

The heat transfer plates in the assemblies have spaced apart dimples for maintaining plate spacing and oblique undulations with the undulations on adjacent plates preferably extending at opposite oblique angles.

在组件(40)中的传热板(44，48)具有用以保持板的间距的相分隔开的凹坑(54，56)，该传热板还具有斜向的波纹，在相邻板上的波纹(52)优选地按相反的斜角延伸。

On the scale of punch and die with punching and bending die punch; Die positioning pulled positioning and bending Die top two pieces of equipment; 6 punch with epoxy fixed on the next model, since blanking punch and bending die role.

上模为凸凹模起冲裁凹模和弯曲凸模作用；模具中定位板起定位和弯曲凹模顶件装置两种作用；六个凸模用环氧树脂浇注固定在下模上，起冲裁凸模和弯曲凹模作用。

Punch and Die blanking punch were different plate fixed to facilitate adjustment gap; Punch and Die blanking die is used overall fixed plate.

模具的冲孔和落料凸模分别用不同的固定板固定，便于调整间隙；冲孔凹模和落料凹模则采用整体固定板固定。

Closed has carried on the reasonable determination highly to the mold, but also designs the mold the major parts to fall the material concave mold, the convex-concave mold, the counter- drawing raised mold, the counter- drawing concave mold, the concave mold dead plate and so on.

对模具的闭合高度进行了合理的确定，还设计出模具的主要零件落料凹模、凸凹模、反拉深凸模、反拉深凹模、凹模固定板等。

This paper presents the present development of rape combine home and abroad and the running principle of typical threshing and separating system. And comparative experimental investigations are done between different threshing and separating systems, such as rasp-bar-plate-tooth drum with grid concave, axial-flow -short-rasp-bar drum with grid concave and spike-tooth drum with grid concave.

本文详细介绍了国内、外油菜联合收割机研究现状及典型的物料脱粒分离系统的工作原理，对油菜联合收割机不同的脱粒分离部件组合的脱粒分离系统——纹杆—板齿-栅格凹板、短纹杆—栅格凹板、钉齿—栅格凹板脱粒分离系统进行了对比试验与研究。

Due to the inherent calcined soil, which makes the solid-ink printing with fast can reduce toner consumption, accelerate the printing speed, Also calcined kaolin-thickness and in a flexible and more suitable for printed, in gravure printing easily slipping through the net and dot defects. 1250 Head of the calcined kaolin paper filler can replace the titanium dioxide to reduce production costs.

由于煅烧土的固有特性，使得在印刷中油墨固着快，可减少油墨用量，加快印刷速度，另外煅烧高岭土松厚度好、有弹性、更适于凹版印刷，在凹板印刷中不易产生漏网和斑点等缺陷。1250目煅烧高岭土在造纸填料中可以代替钛白粉，以降低生产成本。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
