effective surface
2.Reveals the data structure of NURBS trimmed curved surface in IGES files. In accordance with the entity type of MicroStation, the interface program used to read out and identify the IGES files is developed. Based on the MicroStation system, an effective method of measured surface reconstruction is proposed.
3.The system operates on pulse limited mode, transmitting pulses are FM Chirp pulses, the returned signal is processed in receiver in frequency domain instead of time domain by adopting “Full De ramp” technique and frequency spectrum analysis method. Adaptive tracker can remove about 75% of the noise power. High pulse repetition rate results in maximum effective number of independent pulses and are best effective in eliminating ocean surface backscatter speckle noise.
8.It is high-enriched cleaner uscd in hard surface ornamental materials such as marble granite glass wall it is effective in decontamination which no harm to thc surface of exteral wall fast and save troible it is suitable for high altitude which has an obvious effect it can be dilutcd3-50times according to different surface.
