摘要：

Expressions are given for the lengthening of shock waveforms that is caused by their travel upwards to high altitudes. Numerical values are computed for specific examples and pronounced lengthening of the waveform is found to occur. In particular, the N wave from a supersonic transport (SST) is lengthened to a point where it may be a source of interference to geophysicists observing infrasound of natural origin. © 1969, Acoustical Society of America.
