成锥形的

The profile of the sleeve trim shall be that of a cone, reducing conically from a full pipe diameter at the inlet, to reduced diameter at the mid-point of the sleeve, and retaining the reduced diameter through to the outlet of the sleeve.

套管的外形应该是一个锥形，从进口端与管道直径完全一样的截面成圆锥形逐步缩小，缩小到套管的中点，然后保持相同的直径和截面直到套管的出口端。

The fore equipment of Chemical fiber two-for-one twister,fancy twisting machne and cover Yarn Machine make different types material into double cone shape or parallel bobbims for those machines using,and suppoying the yarn merhing function for reguar materials.

化纤倍捻机、花式捻线机、包覆纱机的前道设备，把不同规格的原料筒子络绕成可在化张倍捻机、花式捻线机、包覆纱机上加工的双锥形、平行筒子，可提供一般原料的并丝功能。

Therefore this imaging system can realize two kinds of X-ray radiology: reverse geometry X-ray and X-Scan imaging, and several CT scanning methods, such as equiangular fan-beam CT, equispatial fan-beam CT, helical/spiral CT, cone-beam CT with circle orbit, cone-beam CT with circle-plus-line orbit.

这样就可以实现倒置结构的X射线成像方法、等角扇束的扫描方法，以及本文所提出的凹面源加点探测器的锥形束扫描方法，而且还避免了使用成组点探测器带来的性能不一致性。

Aiming at solving the difficulties of prototype manufacturing of conical ring for the steam generator shell of 600MW Nuclear Reactor,this paper developed a new techniques for the prototype manu-facturing of the great conical ring utilizing ring rolling technology based on RAW200/160-5 ring rolling.

1引言600MW蒸汽发生器壳体是核电站的关键设备，由封头、锥形环件和筒体组焊而成。以往制造这种锥形环件所采用的办法是，先锻制环形筒件再采用机械加工方法成形或者采用自由锻造方法直接在水压机上锻制出大型锥形环件，但这些工艺既费工时又大量浪费材料，而且产品精度不高[1]。

SJSZ Series Conical Double-Screw Plastic Extruder, with relevant screw and auxiliary machine, can directly extrude all kinds of thermoplasticity plastic especially the hard PVC powder into pipes, plate, sheet, film, profiles and so on, can also finish process of reshaping of all kinds of plastics and pelleting of the powder.

今天来说说锥形双螺杆挤出机。SJSZ 系列锥形双螺杆挤出机，配以相应的螺杆和辅机。可将各种热塑性塑料特别是硬聚氯乙烯粉料直接挤出成管。

For each subject, the buccolingual bone thickness was measured by postulating that the miniscrews would be inserted at 16 positions (10, 12, 14 and 16 mm above the median sagittal planes of the interradicular spaces between the first molars and the second premolars in the maxilla, and 30°, 45°, 60°, 90° from the cortical bone surface).

在重建后的锥形线束CT影像上测量上颌第二前磨牙与第一磨牙牙根间矢状面上距离参考平面10，12，14，16 mm的4个植入高度上，以与骨皮质表面成30°，45°，60°，90°的4个方向共16个部位的颊舌侧骨质厚度，计算各植入部位触及上颌窦的危险率，在骨厚度大于6 mm的植入部位模拟植入微螺钉种植体并测量其周围骨质密度。

Each half has a coned section defined by an inner tapered surface (18) and an outer tapered surface (20) such that the halves convert a portion of the first and second axial acoustic energy into radial acoustic energy.

每个半部分具有由内锥形表面(18)和外锥形表面(20)确定的锥形部分，使得半部分将一部分第一和第二轴向声能转换成径向声能。

The cone-shaped spouts above have formed over the years as emitted minerals solidify, and they are still growing.

上图中高高的锥形喷泉口是由于泉水喷出时所携带的矿物质硬化累积而成，现在仍继续累积升高。

In the process of heating, reversing optical panel, the length of fiber almost proportional increased with distance from fiber to center of the plate; at the same time, the shape of fiber changed from cylindrical fibers to cone-shaped fiber that the diameter is change with the length.

光纤倒像器毛坯在这一加热、扭转过程中，纤维长度随着纤维到面板中心的距离近乎成比例增加；同时纤维的形状也由原来的柱形纤维变成直径随长度变化的锥形纤维。

When she lit up her lamp to get up in the morning she found that the snow had blown through a chink in the basement, forming a white cone of the finest powder against the inside, and had also come down the chimney, so that it lay sole-deep upon the floor, on which her shoes left tracks when she moved about.

清晨，当她点亮灯笼起床时，她发现雪已经透过地下室的裂口吹入，堆积成一个细致粉末状的白色锥形，与屋内形成鲜明对比。沿着烟囱飘下的雪花铺在地板上厚厚一层，当她来回走动时，留下一排排的脚印。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
