查询词典 spheroid

Instead, he suggested it was an oblate spheroid—a sphere that is squashed at its poles and swollen at the equator.

相反，他提出地球是一个扁球面——两极稍扁、中间略鼓的扁球面。

So while gleeful anarchists like Oklahoma Senator James Inhofe go to Copenhagen to try to sabotage the proceedings, the worldwide array of newspapers attempts to remind the conference participants and the people they represent to keep their eye on the ball—the ball in this case being an oblate spheroid with almost seven billion human inhabitants and a fever that desperately needs to be treated.

因此，尽管有俄克拉荷马州参议员詹姆斯·英霍夫这样盲目乐观的无政府主义者到哥本哈根气候变化大会上大放厥词，全球的报业同仁们还是用这一联合社论的方式提醒了与会者和他们背后的民众，人类必须对全球变暖保持警惕，因为地球的高烧不退已然威胁到了70亿人的安危。

The results show that the penetrability of powder loads can be improved when suitably reducing bulk density and grain size of gun propellant, increasing nitrogen content of NC and choosing oblate spheroid explosive respectively under the constant test con

结果表明，在其它试验条件不变的条件下，适当降低发射药堆积密度、适当提高发射药中硝化棉含氮量、选用恒面燃烧的扁型药、降低发射药粒度均有利于提高射钉的穿透能力。

Axis of maximum moment of inertia = the axis of figure: because the Earth is not a perfect sphere, but is physically an oblate spheroid, the position of the axis of figure is not a precise constant, but is affected by the constant change in the earth's distribution of total mass:(ie, by ocean tides, atmospheric cond- itions, plate tectonic movements, etc.).

轴最大转动惯量=形状轴：因为地球不是完全的球形，而是一个扁球体，形状轴的位置不是精确的常量，而是受地球总质量的分配持续变化作用：（也就是，受海洋潮汐、大气环流、地质板快运动等等）。

Second, the morphology of martensitic variant of each orientation turns from thin to thick oblate spheroid, which corresponds to the parallel motion of the yield surfaces for different orientations in subsequent yielding. But when grains of each orientation have turned into martensitic phase, the corresponding forward transformation plastic yield surfaces vanish and vice versa.

二是每个取向的马氏体变体形貌从薄的扁旋转椭球体到厚旋转椭球体的长厚过程，对应于每个取向的相变塑性屈服面在后继屈服中平行移动，但当该取向的晶粒全部转变为马氏体后，所对应的正向相变塑性屈服面消失，反之亦然。

The earth is modeled as an oblate and rotating spheroid, and higher order terms in the multiple expansion of gravitational fields are considered. To avoid singularities in computations, the quaternion representation of the spacecraft attitude is used in the angular kinetic model equations.

其中地球被描述为绕短轴自转的椭球体，重力场梯度由四阶Jeffery常数描述，航天飞机的姿态运动用四元素法描述，以避免模型方程中的数值奇异点。

So while gleeful anarchists like Oklahoma Senator James Inhofe go to Copenhagen to try to sabotage the proceedings, the worldwide array of newspapers attempts to remind the conference participants and the people they represent to keep their eye on the ball-the ball in this case being an oblate spheroid with almost seven billion human inhabitants and a fever that desperately needs to be treated.

所以当兴致昂扬的无政府主义者像奥克拉荷马州参议员詹姆士英赫夫去哥本哈根，试图破坏程序，世界上大量的报纸企图提醒会议的参加者和他们所代表的人民，要紧盯著那球，那是个有七十亿人口定居，还有著迫切需要治疗的高烧的扁圆。

The flow fields around a prolate spheroid were investigated by numerical simulation and experiments when the flow is both in laminar state and in turbulent state.

本文利用数值模拟和实验方法研究了层流和湍流状态下绕椭球的流场，主要目的是探索复杂流动情况下的湍流计算方法。

In experimental research, structures of the skin friction lines appearing on a prolate spheroid in laminar and turbulent flows were investigated and compared by using an improved oil-flow visualisation technique.

在实验研究中，用改进的油流显示法研究和对比了层流和湍流状态下绕椭球流动的表面摩擦力线结构。

Thus the distribution of surface field and near field can be obtained..Numerical results for sphere and prolate spheroid are in excellent agreement with thos...

本文给出的球体及长椭球体的数值计算结果表明，这种方法可获得与本征函数级数解相当吻合的结果，优于OSRC方法的结果，说明这种方法可能成为一种对现有解析或数值方法的有效替代方法。

Cable dampener cannot be rolled up but must be hung over the cable.

缆帆不能被卷起，必须保证处于展开状态

"This skylark is a present from my master," he says.

"这只云雀是我主人献上的礼物。"他说。
