圆柱形

The letters were often protected by an envelope of clay on which the recipient's name was written and sealed with a cylinder seal.

文字通常有泥做的封套作为保护，封套上面写着的是容纳者的名字，还盖上了圆柱形印章的封印。

Their first products were rolled steel for saw blades and clock springs, as well as cylindrical steel rods.

他们起初生产用来做锯条和钟表弹簧的轧钢以及圆柱形的钢棒。

The Portable Lightweight Ubiquitous Gasket is a sausage-shaped balloon made of polyester and PVC, and fitted with motorised pumps.

这种装置叫做&便携式通用轻型堵漏包&（其英文缩略语为PLUG，正好有塞子的意思）。它是由聚酯纤维和聚氯乙烯制作的圆柱形气球，并安装了发动机带动的水泵。

When the flowing mass reaches the drain at the foot of the bank it spreads out flatter into strands, the separate streams losing their semi-cylindrical form and gradually becoming more flat and broad,running together as they are more moist, till they form an almost flat sand, still variously and beautifully shaded, but in which you can trace the original forms of vegetation; till at length, in the water itself, they are converted into banks, like those formed off the mouths of rivers, and the forms of vegetation are lost in the ripple marks on the bottom.

当那流质到了路基脚下的排水沟里，它就平摊开来而成为浅滩，各种溪流已失去了它们的半圆柱形，越来越平坦而广阔了，如果更湿润一点，它们就更加混和在一起，直到它们形成了一个几乎完全平坦的沙地，却依旧有千变万化的、美丽的色调，其中你还能看出原来的植物形态；直到后来，到了水里，变成了沙岸，像一些河口上所见的那样，这时才失去植物的形态，而变为沟底的粼粼波纹。

Results of both experiments and simulations show that the detection efficiency of the optimum shape for saddle-like sample box is twice higher than that of cylinder sample.

模拟和实验结果表明，最佳马鞍形样品与目前常用的圆柱形样品相比，其探测效率可提高1倍以上。

Through the calculation of surface area of dome roof for a series of dome tanks, which have different volume, in our company, and after corresponding techno economic analysis, this paper gives calculation basis for the above mentioned estimation procedure.

文章针对镇海炼化公司圆柱形拱顶储罐检修过程中，其拱顶油漆防腐工程量核算中存在的问题，通过对公司内部不同容积拱顶罐的拱顶面积的计算，并进行了相应的技术经济分析，从而得出了拱顶储罐拱顶油漆防腐工程量的计算依据。

The model of an inductive current-limiting device consists of a primary high-Tc superconducting coil, a high-Tc superconducting cylinder ring as the secondary winding, an iron core and a sub-cooled nitrogen cryostat with a cryocooler.

另外，还提出了一种新型磁屏蔽感应型HTSCFCL，它由一次超导绕组、二次超导圆柱形屏蔽筒、铁芯和液氮冷冻箱组成，利用超导绕组和超导筒，从超导态转变到正常态时，其阻抗的快速上升而限流。

The double cylinder rim lock can be divided into two types, jimmy proof rim lock and the non-jimmy proof rim lock.

但遗憾的是在紧急操作时（如发生火警时逃生就比较困难）没有单锁头方便，容易忙中出错导致延误时机；在双扣锁中，由于锁舌运动时呈垂直方向，所以锁舌一般为圆柱形，锁舌伸出或缩进一般使用钥匙或旋钮进行，故锁舌结构中形成了有自碰及非自碰功能。

From dead-end to open-end, surface velocity increases gradually if the filter passage is shorter and surface velocity of both ends is large than that of middle section if the filter passage is longer. Compared with cylindrical filter, the distribution of surface velocity of conical filter is more uniform.

当过滤通道较短时，过滤元件表面速度沿过滤元件轴向逐渐增大；当过滤通道较长时，过滤元件两端的过滤速度比过滤元件中部的大；同圆柱形过滤元件相比，锥形过滤元件过滤速度的分布更为均匀。

A backing bar assembly (20) has a plurality of positively positionable backing bar units (40) which are retained within an inverted U-shaped housing by semi-cylindrical lifters (68) which are adjusted by adjustment screws (60) connected to the housing.

一种靠背梁组件(20)，具有多个通过半圆柱形的提升机构(68)保持在一个倒置U形的腔室内的可适当定位的靠背梁单元(40)，提升机构通过与腔室相连的调节螺丝(60)进行调节。
