To overcome the difficulty caused by the fact that the Lax pair depends on thesolution of the equation as |k|→∞,we write the Darboux matrix with N-poles inthe form:〓,where factor 〓 is a gauge transformation which isindepent from k and 〓 tends to the unit-matrix I as |k|→∞.

为了克服当|k|→∞时，Lax对仍依赖于方程的解所引起的困难，我们把含N对极点的Darboux矩阵〓分解为两部分：〓，其中〓为与参数k无关的2×2矩阵，它相当于一个规范变换。而〓当|k|→∞时趋于单位矩阵I。
