通过广义条件对称方法得到了其对称约化和精确解。
Its symmetry reduction and exact solutions are obtained through the generalized conditional symmetry approach.
也就是说，一般多线性变量分离可解性在对称约化下从高维系统到低维系统得到了保持。
Namely, the applicability of the method is retained from high dimensional systems to low dimensional systems in the symmetry reduction sense.
在每次约化后，余下的方程是保持对称和带状的。
After each reduction, the remaining equations remain symmetric and banded.
