At first an analysis of the basic principles of the vertical - axis variable - pitch turbine is given including two methods to calculate the induced velocity. one is the three different streamtube - methods which are single - disk single - streamtube ( sdst ), double - disk single - streamtube ( ddst ) and multi - streamtube ( mtt ) method based on the momentum theory, the other is the vortex method ( vtth ) based on the potential eddy theory
一是根據動量定理的流管模型得到的求解誘導速度的單盤面?單流管方法（ sdst ） 、雙盤面?單流管（ ddst ）方法、多流管（ mtt ）方法；二是根據勢渦理論得到的求解誘導速度的的渦方法（ vtth ） 。 -
In this subject, a new method and technique that applied the error separation theory to test of the surface flaw of axis - like parts using eddy current is proposed for the first time. based on this method, a mathematical model of extracting the surface flaw of axis - like parts is established. then " an automation system for the eddy current examination of the surface flaw of axletree " is designed
本課題首次應用誤差分離理論提出了對軸（孔）類工件表面缺陷進行渦流無損檢測的新方法和新技術，建立了基於該方法的提取軸（孔）類工件表面缺陷的數學模型，並設計了「軸承滾子表面缺陷渦流自動化檢測系統」 。
