韩廷武, 韩莹洁 · 微分方程年刊：英文版 · 2003
This article begins with the calculating of the conservative density of Kdv equations. By an easy method of calculating the conservative density of a class of nonlinear evolutionary equations is then derived. The calculating of a lot of undetermined coefficients can be dealt with in batches, and it will enable us to operate by hand.
