So the heroic lamb flies from the atmosphere Antarctic at a supersonic speed, who then corrects them with a photoelectric tactic synthetically.

故此，英勇的小羊从南极的大气层以超声速飞来，并用一个综合的光电策略观纠正了他们。

If we sit still and talk we are, from the physical point of view, creating sound waves, which spread from their resting source with the velocity of sound in air.

如果我们静坐着说起话来，从物理学的观点来说，我们在创造声波，这种波从静止的声源以空气中的声速传播。

Meanwhile, the ultrasonic velocity shows a dramatical softening around 70K, while a pronounced upturn in resistivity was observed .

随着氧含量的增加，样品的电荷有序态被破坏，声速在低温下没有发生明显的异常。

For a gas medium, the levitation force is determined not only by the ratio of its density to sound speed, but also by the ratios of its wavelength to the geometric parameters of the levitator.

发现不同媒质中产生的最大悬浮力不仅取决于媒质密度与声速之比，还取决于该媒质的波长与悬浮器几何参数的相对大小。

Part three: numerical simulation on the supersonic chemically reacting flow field in the combustors.

主要工作包括三部分：第一，雾化后的燃料液滴和气态燃料在燃烧室的超声速气流中混合问题的数值模拟。

This is impractical for engineering problem. It is necessary to break the shear layer in order to enchance mixing. It is very useful for combustor design with cavity or dual-cavity. In such combustor the fuel jet can break the

要使超声速混合增强，必须打破稳定的剪切层，燃烧室采用凹槽或双凹槽设计是一种行之有效的方法，它产生的燃料射流就能打破剪切层，从而使混合和燃烧效率进一步提高。

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。
