In chapter 3 we first show some important distributional characteristics of weak derivatives of bvh and sbvh functions as radon measures and we also give some sufficient and necessary conditions that a bvh function becomes a sbvh function 第三章我们先讨论heisenberg群h ~ n上有界变差函数和特殊有界变差函数的弱导数作为radon测度的若干重要分布特征。
