The absolute velocity was decomposed based on the law ofvelocitytriangle, the absolute tangential velocity, the relative velocity and the relative tangential velocity were presented in this paper.
The efficiency distribution along blade span and the inlet and outlet velocitytriangle measurement of rotor blades were made around the designing point.
在设计点附近作了沿叶高效率分布及动叶进、出口速度三角形的测定。

A robust correcting method for discrete spectrum in CW radar velocity measuring is proposed in this paper, t is named the method oftriangle.
