验证算例包括超声速、亚声速以及极低速情形的化学反应流场，计算结果表明基于预处理AUSM+格式发展的算法能够有效地用于全速域范围内化学反应流动问题的模拟。

Unlike in subsonic and transonic speed regimes, the interference resulting from the finite size of the test region is seldom present.

不像在亚、跨音速区域，这里因试验段尺寸有限造成的干扰是难得存在的。

Unlike in subsonic and transonic speed regimes, the in terference result in g from the f in ite size of the test region is seldom present

不像在亚、跨音速区域，这里因试验段尺寸有限造成的干扰是难得存在的。

When the spaceship returned to start procedures to return module down to 15 km away from the ground, it was the pneumatic resistance attack it suffered gravity, a drop from supersonic speed reduced to subsonic and stability in the 200 米/秒 about time to slow down on the parachute on.

当飞船启动返回程序，返回舱下降到距地面15公里时，它所受到的气动阻力近似于它所受的重力，下降速度由超音速减到亚音速，并稳定在200米／秒左右，这时再减速就要靠降落伞了。

Thirdly, the subsonic, transonic and supersonic flutter critical speed of wings and aircraft is numerically simulated. Some numerical results are in good agreement with experimental data.

分别以某后掠机翼和超临界机翼为算例，对机翼的静气动弹性问题以及基于静气动弹性的型架外形优化设计和飞行姿态确定进行研究，计算结果和有关文献的结果进行了比较，吻合很好。

The objectives are the subsonic and supersonic zero-lift drag coefficients, the maximum lift-drag ratio, the maximum lift coefficient at low speed, the average and maximum value of forward and sideway RCS.

目标函数取为亚音速及超音速时的零升阻力系数、最大升阻比，低速时的最大升力系数，以及飞机前向、侧向的RCS平均值、最大值。

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。
