1、The amplitude spectrum line and the amplitude spectrum function are proposed for the airborne particle scattering light signal, and their properties are studied in probability space.
2、Effect of striking point and striking dynamics on the amplitude spectrum of piano signals;
3、It is obvious that the asperity size effects on the amplitude spectrum.
4、Finally, the effect of striking force and striking point at string on the amplitude spectrum are discussed.
5、The radially averaged log amplitude spectrum of potential field can be modeled by lines with different slopes, which are the depths of the corresponding equivalent source layers.
6、The paper expounds a way to get stress amplitude spectrum of main girders of overhead traveling crane through computer simulation combining virtual prototype technology and computer random simulation.
7、Phase-matched filter is applied to extract phase of fundamental surface wave, and then time-variable filter is used to correct amplitude spectrum in order to isolate fundamental mode signs.
8、The main contributions of this thesis are summarized as follows: 1 Proposed a method using amplitude spectrum and reflective symmetry of key frames as gait features to recognize test sequence.
