| 摘 要： | We have obtained two types of two-dimensional similarity reductions for the (2 1)-dimensional Klain-Gordon system using the standard classical Lie group approach with computer algebra.The well-known one-dimension al reductions,radial and travelling reductions are equivalent to the two special cases of our general two-dimensional reductions.
