The dialogue in translation is classified into synchronic dialogue and diachronic dialogue whose functions in the production and evolution of varied versions of the same source text are exemplified.

According to the principle of the method of pseudorange and SLR time comparison,the computation model of the method of pseudorange and SLR time comparison in the non-rotating geocentric system has been derived in the angle of mathematics and geometry,so it is very important for achieving satellite-ground time synchronization in high precision.

Time transfer by laser is the most precise one in several time comparison methods.

Relativistic Theory of Time Transfer and Techniques of Clock Synchronization;

This experiment will enhance the performances of time transfer by 1—2 orders of magnitude compared to existing microwave techniques like GPS and TWSTFT(Two-way satellite time and frequency transfer).

The time transfer method between the land and the ship is a method that guarantees the same time standard in a special area.

Based on the famous phenomenon of simultaneous contrast in biological vision,a new model of anisotropic receptive field used in edges detection is proposed.

Based on the comparison between the mechanism of the simultaneous contrast in biological vision and the anisotropic high-pass filtering and the analysis of the relation between the filtering performance and the angle of the edges and the orientation of the filter s long axes,an anisotropic high-pass filtering scheme on the basis of angle searching is proposed in this paper.
