摘要
在这份报纸，基于分离零个弯曲代表， isospectral 和 nonisospectral 格子层次被建议。借助于解决相应分离光谱方程，我们表明存在无穷地为这的许多能量守恒定律二个层次并且获得相应保存密度和联系流动的公式。
In this paper, based on the discrete zero curvature representation, isospectrai and nonisospectrai lattice hierarchies are proposed. By means of solving corresponding discrete spectral equations, we demonstrate the existence of infinitely many conservation laws for this two hierarchies and obtain the formulae of the corresponding conserved densities and associated fluxes.
