本文介绍一种利用柴油机高压泵喷油管壁上的压力波脉冲信号，来测量柴油机转速的新方法。
The paper introduces a new rotating speed measuring method for diesel engine utilizing pressure pulse signal on the tube wall of high pressure fuel injection system of diesel engine.
最近，在对526名男女的调查中，研究人员发现，在坐地前伸测试中最灵活的人也有最柔软的动脉，这个结果和脉冲波压力测试一样。
In a recent study of 526 women and men, researchers found that those who were the most flexible on a sit-and-reach test also had the most supple arteries, as measured by a pulse-wave pressure test.
根据激波理论，爆炸产生压力脉冲并以压力波的形式传播，既有压缩波也有膨胀波。
According to the shock theory, the ejecta produced by explosion form the pressure pulse, and it spreads in forms of either compression waves or expansion waves.
脉冲的大小又取决于冲击波的延续时间及其压力。
The impulse is dependent upon the duration of the shock wave as well as its pressure.
在隧道出口处，产生一种叫做微气压波的压力脉冲，并造成环境问题。
The micro-pressure wave is similar to the aeronautical sonic boom and caused serious environmental damages.
