The tomographic approach which basic unit is rectangular block can model and inverse the complexvelocity structure.
这种层析反演方法以块体为基本单元，可以模拟和反演复杂速度结构。

Finally, we give as an example the calculation of complexvelocity potential for a twisted duct with square cross-section.
最后给出了一个方形扭曲管的复速度势计算实例。

The formulae of the complex potential, the complexvelocity, and the pressure coefficient in the triangular flow are derived, and some typical expamples have also been given.
