In this paper, the approximation of order parabolic equation is studied with the anisotropic biquadratic element.

The global topological structure of the biquadratic systems is discussed and their coefficient conditions are given.

讨论了一类齐四次系统的全局结构,并给出了它们的系数条件.

That leads to biquadratic equations for solution.

它们又引出待解的双二次方程.
