It is widely used to develop complex functions into Laurentseries at the neighborhood of a pole.
在数学中经常要用到复变函数在极点邻域内展开的罗朗级数。

It is assumed that the plate is in close contact with the ring without initial stresses. Stress functions of the plate and the ring are formed by a complex Laurentseries.
假设板与环间处于无初应力的紧密接触状态,弹性板和弹性环的应力函数都可按复劳伦级数展开。

The complex potentials were expanded into LaurentSeries whose coefficients could be expressed by recurrent relations. The stresses and displacements were then be determined by complex potentials.
