Introduction Intermetallic compounds based on Ni3Si have been considered as the basis of high-temperature structural materials and chemical parts because Ni3Si displays an increasing strength with temperature increasing and also shows excellent oxidation resistance and corrosion resistance over a wide range of temperature[1,2].
Experimental Procedures Ni-based superalloy plates, 20 mm × 15 mm × 10 mm in size, were selected as the substrate material for laser cladding treatment.

At present, the research about Lake wetland aquatic vegetation remote sensing image classification is less, in this paper I use two spectral images the Moderate Resolution in August 2001 of Landsat the ETM + and Landsat TM in August 2010 over, based on the spectral information of base material, establish classification decision tree adopting single-band, the band difference, owned by one of the vegetation index (DNVI) and water body index (NDWI) and other auxiliary information, extract the vegetation information of very water and submerged in the lakes wetlands, research aquatic vegetation evolutionary trend in Wuliangsuhai lake in the past 10 years, and provide some theoretical basis and technical reference for the evaluation of lake the effect of environmental evolution and the ecological environment project.
