在简要分析多小波的逼近性与平衡性的基础上
通过简短的证明得出了具有一定平衡阶的多小波系统
其相应的多尺度函数必具有相同阶逼近的结论.在引入了多小波不同于单小波的插值条件后
得到具有一定逼近阶的多尺度函数
如果同时满足插值条件
则相应系统必然具有相同的平衡阶的结论.
On the basis of a simple analysis of approximation and balance of multiwavelet
a simple proof is given to deduce that a multiwavelet system with given balancing order must have a multiscaling function with the same approximation order.After introducing the special interpolating condition of multiwavelet
the conclusion is that if a multiscaling function has a given approximation order and satisfies the interpolating condition simultaneously
the corresponding system consequentially has the same balancing order.
