The old choppy and clunky pre-swing rhythmic feel is still there in the pulse and banjo sound, but this was a new notion of how jazz composition might evolve.

在这首曲子的弦乐的跳跃中，虽然我们仍能感受到摇摆音乐前期爵士乐在节奏上的生涩滞落，但此时其作曲的新走向已略显初端。

In this paper, the interaction between a cw plane wave and a plane pulse travelling with sound speed is considered. Both of them satisfy the homogeneous wave equation.

本文讨论一列平面波与一列平面行波脉冲的声相互作用，显然这两个波不仅都满足波动方程，而且可以用来讨论公共区之外的声散射声问题。

This paper develops a theoretical formula for calculating interfacial noise of vibrating point from its vibratory quantity with pulse semisphere sound source as basic physical model.

本文以脉动半球声源为基本物理模型，推导了由振动量计算振动点的界面噪声的理论公式。

The machine that Dr O'Brien and Dr Frazier have designed to get round these constraints consists of a transmitter that sends out a pulse of sound at a frequency of 6 kilohertz, and an array of 52 receivers that collect the reflections from anything buried beneath the surface.

The continuous pumping means the patient's pulse is replaced by a constant whir - similar to the sound of a washing machine.
