The effect of pressure-holding time and pulse amplitude on the gas nitrocarburizing layer depth under the given temperature and time condition was investigated.

DC-voltage comparative method and high sampling digital multimeter method can measure the pulse amplitude accurately,but their application is relatively limited.

Time of flight and pulse amplitude are measured from the time of flight counters,when the particle hits on the TOF.

In this paper, three types of typical digital sound sources, pseudonoise, linear sweep, and impulse-shaped signals, are analyzed.

This paper aims to determine the relationship between pulsed amplitude and the area of the instantaneous pressure drop within one-period through five standard spray-sieve-plates pulsed extraction columns by air purge method.
