平整度

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。

Smoothness is the evaluation of the degree of surface concavo-convex an indicator used to represent the paper surface smooth.

平滑度是评价纸张表面凹凸程度的一项指标，用于表示纸张表面平整光滑的程度。

The GPR image is easily disturbed by the level degree of ground, porosity, water content and silt in the riprap layer.

雷达反射波形易受地面平整程度、抛石层孔隙度、含水量及含泥量等因素的影响。

Drawbench plastic production process, because of plastic material contained in the composition of drawing complex, such as PP + renewable PP; PP + inorganic filler; renewable PP + renewable PE and so on; these materials more or less entrainment of water and impurities will directly affect the silk-smooth surface film formation and the tensile toughness of noodle degrees, resulting in mechanical properties of products and sensory quality by a greater impact, broken wires, the membrane surface uneven, dull and so on.

塑料拉丝制品生产过程中，由于塑料拉丝材料所含的成份复杂，如PP＋再生PP；PP＋无机填料；再生PP＋再生PE等等；这些材料多多少少夹带水份和杂质，将直接影响丝面的光滑平整及膜面的韧性拉伸度，从而导致产品的机械性能和感观质量受到较大影响，断丝、膜面凸凹不平、无光泽等现象。

The bare cells with smooth surface presented transverse outspreading effect at mica surface. Great changes took place in surface roughness for those bacterial cells after metallization. A large number of nickel nanoparticles were observed to be equably distributed at bacterial surface after activation and subsequent metallization.

结果显示，空白对照菌表面平整光滑并在云母基底表面表现出较显著的铺展效应；经过活化和化学镀镍后的菌细胞表面粗糙度明显增大，并在基本保持原有菌模板外形的基础上，其高宽比有所增大。

The permeability of the surface smoothing resinified needled filter felt we developed is 50% higher than that of ordinary filter felt.

我们开发研制的表面树脂化光滑整理针刺过滤毡，其透气度比普通压光整理滤料高出 50%以上，而表面的光滑程度比经压光整理更加平整光滑。

For the powder having burn out process, the densification of the films is higher under carrier gases Ar,O2,N2. The surface roughness also increases with increasing gas flux.

初始粉末经烧除后镀制之厚膜结构，以Ar，O2或N2携带气体下最为致密，且膜厚及表面形态差异并不大，可发现较为平整之膜面，但随著流量的提升，表面的粗糙度则会增大。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
