Core saturation and the rotor bar skin effects were directly taken into account in the field calculation. The adopted circuit equations are suitable for describing the stator windings and the special rotor-bar connections of BDFM. The waveform of supplied voltage source may be an arbitrary. Three-dimensional end effects were considered in the circuit parameter corrected by classical formulas. In addition, the coupling and constraint equations were used to handle rotor rotation without any process of remeshing.

While the standard Airy function, used frequently in the uniform asymptotic formulas for classical orthogonal polynomials, behaves like the exponential function on one side and the trigonometric functions on the other side of an extreme zero,the q-Airy polynomial behaves like the q-Airy function on one side and the q-Theta function on the other side.

在经典正交多项式的一致渐近公式中我们通常要用到Airy函数，这个Airy函数在一个极端零点的一边表现为指数函数，另一边又表现为三角函数。同样地，q-Airy多项式在一边表现为q-Airy函数，另一边又表现为q-Theta函数。
