圆柱

Replacing the total reflecting mirror in the plane-parallel resonator by a compound TIR prism (so-called a plane-compound TIR prism resonator or a TIR prism resonator for short), the offset of output faculae was resolved satisfactorily.

根据泵浦光在聚光腔中的传播规律，提出了一种适合于小型化器件的相交圆柱聚光腔的设计方法。本文通过大量的实验和理论研究，完成了工程化的小型Cr〓：YAG被动调Q重频热传导自然冷却：YAG激光器的结构和参数设计，并确定了器件的最佳工作点，最后完成了样品机的生产。

Our first products on the market were cylindrical gages, or ring and plug gages as they are more commonly called.

我们的第一种产品是圆柱规类，也就是通常所使用的环规和塞规。

One of the goofs in this film: When Mike is outside the library, there are no columns outside, but when he enters, the shot from inside the library shows one.

电影中有一个这样的穿帮镜头：当迈克在图书馆外的时候，外面并没有圆柱。可当他走进图书馆，从里面望出去时，却有根柱子立在那里。

Material removal characteristics of ultrasonic gritting are discussed in this paper by ultrasonic gritting Al_2O_3 ceramic cylindrical workpieces.

通过对Al2 O3陶瓷圆柱零件的超声研磨试验，探讨了超声研磨时材料的去除特性。分析了研磨参数、油石粒度对材料去除率的影响，给出了超声研磨加工比普通研磨加工效率高的主要原因。

Spikelets with 1 floret (to 3 in Duthiea ), terete or laterally compressed, disarticulating above glumes; rachilla extension usually absent (present in Stephanachne , Sinochasea , and Duthiea ); glumes equaling or longer than floret, persistent, hyaline to membranous, 1–7-veined; floret callus obtuse to pungent; lemma rounded on back, membranous to leathery, firmer than glumes, often indurated at maturity, 3–9-veined, often enclosing palea, apex entire or 2-toothed, awned from apex or between teeth; awn straight or geniculate, glabrous, pubescent or plumose; palea subequal to lemma, hyaline to membranous, usually 2-veined (5–7-veined in Psammochloa ) but not keeled, apex usually acute.

小穗具1小花(对3在Duthiea里)，圆柱状的或侧面压扁，高于颖片脱节；小穗轴扩展通常无(在Stephanachne，Sinochasea 和Duthiea里提出)；颖片等长或更长于小花，宿存，到膜质，1-7脉；对刺激愚蠢的小花结茧；外稃在后面上绕行，膜质到革质，比颖片坚定，芒直或者膝曲，无毛，青春期或者羽状；内稃近等长于外稃，透明的到膜质，通常2脉的(在Psammochloa里的5-7脉)但不是翻转，先端通常厉害。

You may have to make them the real shape of logs.

你可以把它们弄成真正的圆柱状。

Furthermore, as the oscillating frequency of the cylinder approach the natural vortex shedding frequency, because of the phenomenon of resonance in the channel flow, and the heat transfer rate is enhanced more remarkably.

此外，当圆柱振动的频率接近流场的自然振动频率时，会与管道内的流体产生共振的现象，此现象能够大幅的增加流体的扰动，并且扰乱管道内的流场以及温度场，产生较佳的热传增益。

"In 17th-18th-century Britain, long covered walks or galleries with roofs supported by columns were called piazzas; in the U.S. in the 19th century, piazza was another name for a veranda formed by projecting eaves."

在17至18世纪的英国，长而有屋顶的人行道，或长廊设有由圆柱支撑的屋顶，也称为柱廊；在19世纪的美国，这个字则是，突出的屋檐所形成的阳台的另一名称。

These porticoes are arranged in semicircles along the short sides of the square and consist of four parallel rows of Tuscan-Doric columns which provide a choice of three paths.

这些柱廊都被排列在半圆沿短期双方的广场和包括四个平行排托斯卡纳，陶立克式圆柱，提供一个选择的三条道路。

To satisfy the requirements of fast producing,low cost manufacture and large thickness preforming in the field of non-resin winding cylinder composite,the equation of retracing cosine curve was deduced based on the section principle.

为使复合材料圆柱壳体预制件适应短周期快速生产、低成本、壳体厚壁成型的要求，基于缠绕区段划分原理推导出端部余弦折回曲线方程，并结合传统纺织理论，推导了余弦折回曲线模型下端部特征参数计算公式。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
