摘要：
We discuss a series of models introduced by Barashenkov, Oxtoby, and Pelinovsky to describe some discrete approximations of the phi(4) theory that preserve traveling kink solutions. Using the multiple scale test, we show that they have some integrability properties because they pass the A(1) and A(2) conditions, but they are nonintegrable because they fail the A(3) conditions.
