In this paper, a dynamic calibration method using a finite duration impulse excitation source is presented, which can be used to calibrate the frequency response of high-pressure transducers (HPT).

本文提出了用任意时限脉冲作激励源的一种动态校准方法，用于校准动压传感器的频响特性。

Realistic signals are made by summing sine waves of lots of frequencies, so that after some finite number of wavelengths they interfere destructively and you get a signal of finite width and duration.

现实中的信号由各种频率的正弦波组成，因此，在有限的波长数后，它们会干涉相消，你就得到一个有限宽度和有限延续的信号。

In every case, however, the duration of a project is finite. Projects are not ongoing efforts.

然而，在任何情况下项目的期限都是有限的，项目不是持续不断的努力。

Moreover, CBT intentionally is finite in duration.
