Then, summing up experience in engineering practice, the author studies the basic characteristics and reason of transverse reflection wave appearing on the top of pile, as well as indicates the method for elimination of transverse wave interference on the top of pile.

Because of some people\'s traffic awareness is relatively weak, pedestrian and non-motorized horizontal interference greatly reduces the efficiency of trunk line intersection signal-controlled system.

The study of wavelet transform on harmonic interference of the power system;

This paper introduces the effect of conduction interference,radiation interference and harmonic interference for electronic ballast inverter.

Improvement of method eliminating single-frequency interference wave in time domain;

Based on the principle of two dimension filtering and on the distribution difference of f-k spectra between interference signals and usable signals, it is shown that two dimension filtering can effectively remove interference waves (such as diffracted waves from air or side whose apparent velocities are different from those of usable reflections) from the image of GPR profile.

Combined with the practice of seismic prospecting of stake base,this paper has discussed the characteristics of different interference waves and the application of anti jamming measures.

Theoretical research of noise waves resulting from dynamite point source.;
