头部形成

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。

A vertical board or panel forming the head of a bedstead.

形成床架头部的一个直立的板或嵌板。

They communicate the laity everywhere not only under the form of bread but also under that of wine, and they stubbornly assert that they should communicate even after a meal, or else without the need of a fast, contrary to the church's custom which has been laudably and sensibly approved, from the church's head downwards, but which they damnably try to repudiate as sacrilegious.

他们沟通俗人无处不在，不仅下形成的面包，而且根据酒的，他们顽固地认为他们应沟通后，即使是吃一顿饭，否则，如果没有需要的是一个快速，违背了教会的习俗已laudably理智批准，由教会的头部向下，但它们damnably试图推翻，因为亵渎。

The constant search for a more effective infantry weapon led in the 1990s to the concept of small-calibre high-explosive fragmentation grenade shells designed to burst over the heads of their targets, thereby permitting the attack of troops in defilade, ie hiding behind cover.

源于上世纪八十年代的对更加有效的步兵武器的不断研究得出了小口径高爆破片手榴弹的外壳设计用于杀伤目标头部的概念，从而形成了对隐藏于工事及掩体的部队进行攻击的手段。

The observation results show that vulture has huge body, black woolfleece, circle nares, epicranium quill - coverts. There is white skin fold ruff at cervix near head.

结果表明：秃鹫体形庞大，被毛黑色，鼻孔圆形，头被绒羽，颈部靠近头部的部分为污白色皮褶形成的皱领。

However, by taking advantage of the steric restriction offered by the three ethoxyl groups on the heads of the C8TES molecules, as well as the difference of the chemical activities between the OTS and C8TES molecules, it was possible to construct both the homogeneously and phase-separated mixed C8TES/OTS SAMs by means of the stepwise method.

但是利用C8TES分子头部三个乙氧基所形成的空间位阻以及C8TES和OTS分子之间反应活性的差异，采用分步法可以制备出混合均匀的均相和相分离(Phase-separated)的C8TES／OTS混合自组装单分子膜。

Tie down the foam and form the head of the cricket...

把泡沫绑起形成蟋蟀的头部。。。

The exhibition hall for culture, art and education forms a 'tail' and 'body' to the dragons, while the convention centre rises up to form the head of the complex.

展馆文化，艺术和教育形成了一个'尾巴'和'机关'的巨龙，而会展中心升起，形成头部的复杂。

He keeps his head and body stable... and in a very horizontal line in the water.

他的头部和身体保持稳定，在水中形成一条水平线。

The research indicated that, the structure inside the pure C8TES SAM was indeed loose and unassembled completely, the molecule density inside the SAM was very low, which would result in an ultra-low surface contact angle, only 20～21°, on the C8TES SAM surface.

我们的研究表明，由于C8TES分子头部三个乙氧基形成的空间(来源：b5e5ABe3C论文网www.abclunwen.com)位阻的影响，C8TESSAM的内部处于一种不完全组装的松散状态，所形成的自组装单分子膜内分子密度偏低，造成C8TES SAM的表面接触角偏低，只有20～21°。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
