point reflection
1.According to their space position, the seismic features of shallow gas in this region can be divided into three groups: (1) features in the stratum: acoustic blanket, acoustic curtains, acoustic turbidity, irregular strong top reflection boundary, and phase pull-down in both flanks; (2)features of the seabed: seabed pockmark and giant sunken pit; (3)features in the seawater column: acoustic plumes, cloudy turbidity and point-line-type reflection.
3.Price dispersion, defined as the distribution of prices of an item across sellers in one market at a given point time, is the comprehensive reflection of market structure and the information flows state.
4.From a point of view of self-reflection, Habermas has revealed the relation of knowledge to interest, criticized the positivist epistemology and its view of science and paved the road to the construction of basis of social critical theory.
6.In the counting system, a semiconductor laser emitter is used as the light source, point laser beam produced by optic system, reflection of part transferred into electric signal by photoelectric triode, and SCM system as the counter.
7.It is also point out that, as a theoretical concept, AFA is both a reflection of administrative relation in practice and aresult of conflicting theories.
8.As the common mid-point (CMP) stacking is hard to get a good effect in the complicated geological structure in seismic data processing, the common reflection point(CRP) stacking is used.
9.A numerical method for the point defect impact in transmission fibers on back-pumped fiber Raman amplifiers (B-DFRAs) is derived, accounting to both loss and reflection effects. Characteristics of gain, amplified spontaneous Raman scattering and double Rayleigh backscattering in a B-DFRA with point defect are studied separately, and the comprehensive effect of the point defect is discussed by equivalent receiver sensitivity.
10.Abstract: In this paper the characteristics of reflection waveform of embedded rock piles are studied from the point of theory and practice.
