The horizontal low velocitylayer, the vertical low velocity zone and the highvelocitylayer in the basement of the lower crust are related to the ore_forming processes.
The geothermal anomaly, low velocity zone and high conductivity layer in crust, and frequent occurrence of strong earthquakes show that the study area is an active area of modern tectonization.
地热异常、地壳内存在低速层和高导层、强烈地震频繁发生等现象说明,这一地区是现代构造运动的活动区。

Under highvelocity flow conditions, cascade losses are mainly caused by radial drift of the boundary layer along the suction surface and by blade wakes.
