研究了有界变分函数对称重排的作用。特别地，建立了逐点正则化效应。证明了Polya-Szego型不等式，并给出了相等情况的刻画。
The action of the symmetric rearrangement of functions of bounded variation is investigated. In particular, pointwise regularizing effects are established. Polya-Szego type inequalities, with a characterization of equality cases, are also proved.
