本文对已有的“协因子”算法进行了改进，并构造了二阶有限元双正交多尺度函数。

So, this method is modified in the article, and the finite element biorthogonal multiwavelets are constructed.

结果表明，如果我们想从多尺度分析出发构造正交小波，那么该多尺度分析必须有正交尺度函数。

This result shows that if we want to construct orthonormal wavelets from a multireso- lotion, then that multiresolution must have an orthonormal scaling function.
