尖顶

Downstream axially from nose apex to afterbody,a local sectional-side-force extremum always presents itself behind the forming of the corresponding shed vortex and new lee-side vortex.

沿轴向从头部尖顶往后体，截面侧向力局部极值的形成总是滞后于相应脱落涡、新生背涡的形成，截面侧向力局部极值的大小同时取决于相应脱落涡、新生背涡的形成方式和相应背涡的强度。

1The axial evolution law on the structure and the aerodynamic characteristics of the asymmetric flows around slender bodies of revolution at incidences is summarized:whether the flow asymmetry is powerless or powerful,the flow always appears in the structure that lee-side vortices rise,and shed vortices form,and new lee-side vortices come into being alternately on opposite sides of a slender body of revolution axially from nose apex downstream to afterbody,and always induces the sectional side force of waving quasi-sinusoidally downstream axially.

1总结出细长旋成体有攻角非对称绕流流场结构和气动力特性的轴向演化规律：无论非对称性强弱，沿轴向从头部尖顶往后体，非对称绕流总是呈现为左、右两侧背涡交替从物面向上飘起、形成脱落涡、再衍生出新生背涡的流场结构，并诱导出沿轴向呈类似正弦曲线形式振荡分布的截面侧向力。

The air wedge angle can be computed with application of the unitary linearity regress method in fitting the relation between the serial number of the CCD pixels and the serial number of the intensity maximum of interference fringes.

该方法利用待测试件受力产生的形变改变空气劈尖顶角，并用一元线性回归方法对CCD的像元序号与所接收到的干涉条纹光强极大值序号之间线性关系进行拟合，进而确定出空气劈尖顶角大小。

Some of these faubourgs were important: there were,first, starting from la Tournelle, the Bourg Saint-Victor, with its one arch bridge over the Bi鑦re, its abbey where one could read the epitaph of Louis le Gros,~epitaphium Ludovici Grossi~,and its church with an octagonal spire, flanked with four little bell towers of the eleventh century a similar one can be seen at Etampes; it is not yet destroyed

这些关厢村镇有些还是很大的。首先是从小塔作为起点的圣维克多镇，那里有一座在比埃弗尔河上的单拱桥，一座可以看到胖子路易墓志铭(épitaphiumludivicigrossi)的修道院，还有一座有着八角尖顶、尖顶旁有四个十一世纪小钟楼的教堂这样的教堂现在在埃唐普还有一座，还没有拆毁

This paper analyses that tip angle of drill bit influences on cutting capability and life of twist drill, when the material and shape of work piece is different.

分析了工件材料、形状不同时，钻尖顶角的大小对麻花钻切削性能及寿命的影响，介绍了麻花钻的钻尖顶角的选择。

A crowning spire was a key feature of the design from the beginning, including a topmast and a ring of spikes.

从一开始，最高的尖顶就是设计的关键特点，其中还包括了一座中桅和一圈小尖顶。

The point of intersection of two ornamental arcs or curves,such as the inner points of a trefoil.

尖顶两条装饰性弧线或曲线的交叉点，如三叶饰的内尖顶

There are two large pinnacles, or points, on the corners of the tower and a much smaller one in the center.

在塔楼的拐角有两个巨大的小尖塔，或说尖顶，它们中间有一个小得多的尖顶。

St. Petersburg is home to the highest cathedral in Russia, a building that is in fact the highest in the historic center of the city – the Peter and Paul Cathedral, which contains the burial vault of the Romanovs. The height of its bell tower with its gilded spire, topped with the figure of a flying angel, is 122.5 meters.

圣彼得堡拥有俄罗斯最高的教堂，高达122.5米的&圣彼得和圣保罗&大教堂，彼得大帝的葬礼，曾经在此举行，也是这座城市有史以来最高的建筑，由罗马墓葬型的拱顶、钟楼最高点的镏金尖顶、以及尖顶处展翅的飞鹰组成。

The pin top for pre-selecting is welded on the bottom part of the bracket of core drill, the pin top is in favor of the localization of drilling hole, at the same time, it can overcome the reversal angular force acted on the core device, it enhances the rigidity of the whole mechanism.

起预定位作用的尖顶焊接于取芯钻机的机架底部，尖顶有利于钻进初始阶段时钻孔的定位，同时还能够克服作用于取芯器的反转矩，提高了整个机构的刚度。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
