之后，通过求解一个关键性算子方程，得到此类孤子方程族的换位表。

Then through resolving a key operator equation, we obtain the commutator representation of this hierarchy of the soliton equations.

对在对数型非线性介质中空间灰孤子的存在性进行了研究，认为对数型非线性介质中可以同时支持暗和灰空间孤子态。

The existence of dark and gray spatial solitons in logarithmically nonlinear media is investigated. It is shown that both dark and gray solitons are possible in corresponding nonlinear media.
