外形

Rail grinding has become increasingly popular as a means of correcting surface damage to rails,and also controlling wheel contact position and railhead profile.

钢轨打磨作为解决钢轨表面缺陷、控制轮轨接触位置和控制钢轨外形的手段，应用越来越广泛。

The contours of the leg suggest this creature to be human, an athlete, a dancer, or maybe even a tribal rainmaker deep in ritual motion.

从那腿的外形来看，这显然是个人，是个运动员，或是舞者，或甚至是沉醉在仪式舞蹈中的求雨巫师。

Then shape optimization under the rarefied flow conditions becomes very important in order to improve the vehicle's performance.

因此高速飞行器在稀薄条件下的外形优化对于提高飞行器的性能尤其重要。

But now, when I design the production I don't care the unmeaningful shape,this is the reading lamp.

但是我在做这个作品的时候我就不去设计没有意思的外形，这是一盏台灯。

The smooth sculpture-like exterior of the Pavilion is an image of the arc-shaped rocks rolling endless in Australia's countryside; its exterior wall uses special weather-resistant steel cladding materials the color of the curtain wall will deepen over time until it turns the color of reddle much like the red earth in Australian inland.

澳大利亚馆流畅的雕塑式外形好似澳洲旷野上绵延起伏的弧形岩石，外墙采用特殊的耐风化钢覆层材料，幕墙的颜色将随时间的推移日渐加深，最终形成浓重的红赭石色，宛如澳大利亚内陆的红土。

The primary reasons for a tracked vehicle's compactness are reduced suspension clearance, wheel turning clearance, and the absence of multiple transfer cases and drive shafts that are integral to the design of multiwheeled vehicles.

首先，履带车辆的因为减小了悬挂机构、转向机构并取消了多轮驱动轮式车辆所必不可少的并联的变速箱和驱动轴，因此其外形要比轮式车辆更紧凑。

In the Ti film and the TiZr alloy film annealed at 800 ℃, there are a lot of regular hexahedron or octahedron bubbles, which are the same as the projections of equilibrium shape of their matrix crystal. With annealing temperature of 720 ℃, the bubbles in TiZr alloy annealed for 40 min are more round than those annealed for 130 min.

在800 ℃热处理后的Ti和TiZr合金中均观察到规则的六边形和八边形氦泡，对应基体材料单晶平衡外形多面体的投影。720 ℃热处理40 min后，TiZr合金膜中的氦泡比同样温度热处理130 min后的接近球形。

Analyse the mechanism that revulsive orientaton arranges electric field, and fall in electric field action, the athletic mechanism of the particle of different figure.

分析电场诱导取向排列的机理，以及在电场功能下，不同外形的粒子的运动机理。

The paper introduces aerodynamic configuration optimization design of lower Reynold number aeroplane using genetic algorithm,and makes prototypes to test feasibility and correctness of design.

试验结果表明该优化设计方法是十分有效的，可以用来对具有正常布局形式的飞机进行气动外形的优化设计。

I only lengthened the cannon barrel and relocated it on the right shoulder and modified the riffle.

这个模型我没有作出很多修改，只加长了大炮管和把大炮放在右肩上，以及修改了枪的外形。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
