爆震波

In considering the destructive effect of a blast wave, one of its important characteristics is the overpressure.

在研究爆震波的破坏作用时，其中一个重要的特性便是超压力。

The shock wave is similar in general form to the blast wave in air, although it differs in detail.

这种冲击波的一般形式与空中爆震波相似，然而在细节方面却又不相同。

There may also be an increase in the velocity of air particles in the blast wave due to precursor action.

由于前驱波的作用，爆震波中的空气粒子速度可能增加。

These have been developed by the numerical integration of the differential equations of gas motion for a spherical blast wave in air.

这些都是根据空中球形爆震波气体运动的微分方程的数值积分得到的。

As the depth of burst increases, the amount of energy going into the air blast wave decreases.

随着爆炸深度的增加，转化为空中爆震波的能量便减少。

The blast wind has then effectively ceased and the direct destructive action of the air blast is over.

爆震风已有效地停止了，于是空中爆震波的直接破坏作用就完结了。

It also indicates that the model of pulse detonation engine is right and the data acquiring system is reliable.

结果表明该实验原型可以产生脉冲爆震波，自主研制的数据采集系统满足脉冲爆震发动机测试系统的要求。

For multicycle detonation, if the length of cooling tube is short enough, the detonation pressure can be measured.

当通过冷却套管来测量多循环PDE爆震室压力时，采用较短长度的套管，可以得到爆震波压力。

Pulse detonation engine is a new concept of propulsive engine which uses high temperature and pressure gas produced by intermittent or pulsant detonation wave to generate thrust. PDE has many desirable advantages, including high thermal dynamic cycle efficiency, low specific fuel consumption, high thrust/weight and specific impulse, simple configuration, and will become propulsive device of aviation and spaceflight aerocraft in 21st century.

脉冲爆震发动机是一种利用间歇式或脉冲式爆震波产生的高温、高压燃气来产生推力的新概念发动机，这种发动机具有循环热效率高、燃料消耗率低、推重比高、比冲大、结构简单等优点，将成为21世纪新型的航空航天飞行器的动力装置。

It's found that successful two-phase pulse detonations can be achieved in tubes with diameters less than cell size of mixtures.

研究发现，在内径小于混合物胞格尺寸的爆震管内，可以形成充分发展的两相脉冲爆震波。

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。
