The application of plasma spray is the most popular method by which a metal-bioceramic surface composite can be prepared for the repair of biological hard-tissue, but this method has disadvantages. These disadvantages include poor coating-to-substrate adhesion, low mechanical strength, and brittleness of the coating. In the investigation described in this(More)
This paper used PS-InSAR method to monitor the landslide along Qing river. Several typical landslides area were selected as the experimental areas. 61 ASAR data have been processed, which were acquired from 2003 to 2010. The obtained preliminary deformation rate map not only included the experimental areas, but also showed several new landslides areas. The(More)
in the paper, the influence of different inflow water rate and temperature on heat exchange performance of underground heat pump were discussed by experiment, two vital parameters was defined to measure the properties of ground heat exchanger: Energy Efficiency Coefficient and Heat Exchange Utility Time. The experimental results showed that whether in the(More)
