As an application of gauge transformation, we construct Darboux transformation (DT) of this new equation through DT of Ragnisco-Tu equation. An explicit exact solution is presented as an example. %K Ragnisco-Tu Hierarchy %K Gauge Transformation %K Transfer Operator %K Darboux Transformation %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=60687
